of genetic variation and multiple accurate selection criteria for discriminating their salt tolerance. A combination of morpho-physiological and biochemical parameters and multivariate analysis was used to detect salt tolerance variation in 15 wheat lines developed by doubled haploid (DHL) technique. They were then compared with the salt-tolerant check cultivar Sakha 93. Salinity stress was investigated at three salinity levels (0, 100, and 200 mM NaCl) for 25 days. Considerable genetic variation was observed for all traits, as was high heritability (>60%) and genetic gain (>20%). Principal component analysis indicated the ability of nine traits (root number, root length, root dry weight, shoot length, shoot dry weight, specific root length, relative water content, membrane stability index, and catalase) to identify differences in salinity tolerance among lines. Three traits (shoot length, shoot dry weight, and catalase) were indicative of salt-tolerance, indicating their importance in improving and evaluating salt tolerant genotypes for breeding programs. The salinity tolerance membership index based on these three traits classified one new line (DHL21) and the check cultivar (Sakha 93) as highly salt-tolerant, DHL25, DHL26, DHL2, DHL11, and DHL5 as tolerant, and DHL23 and DHL12 as intermediate. Discriminant function analysis and MANOVA suggested differences among the five groups of tolerance. Among the donor genotypes, Sakha 93 remained the donor of choice for improving salinity tolerance during the seedling stage. The tolerated lines (DHL21, DHL25, DHL26, DHL2, DHL11, and DHL5) could be also recommended as useful and novel genetic resources for improving salinity tolerance of wheat in breeding programs.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="126cb4f2cd05ce533d63bb620d01af13" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":59312624,"asset_id":39185526,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/59312624/download_file?st=MTczMjc5MjEzNSw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="39185526"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="39185526"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 39185526; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=39185526]").text(description); $(".js-view-count[data-work-id=39185526]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 39185526; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='39185526']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 39185526, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "126cb4f2cd05ce533d63bb620d01af13" } } $('.js-work-strip[data-work-id=39185526]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":39185526,"title":"Detecting Salt Tolerance in Doubled Haploid Wheat Lines","translated_title":"","metadata":{"issue":"4","volume":"9","abstract":"Improving salt tolerance of genotypes requires a source of genetic variation and multiple accurate selection criteria for discriminating their salt tolerance.

Sewage sludge application resulted in greater biomass accumulation in ryegrass than comparable single applications of either synthetic fertilizer or digested sludge. Sewage sludge application resulted in more numerous mycorrhizal spores in soil and increased root colonization in comparison to synthetic fertilizer. All plants studied had mycorrhizal colonized roots, with the highest colonization rate in maize, followed by hemp. Sewage sludge application resulted in the highest P uptake in all soil-grown plants. In conclusion, sewage sludge application increased feedstock yield, provided beneficial use for organic wastes, and contributed to the sustainability of bioenergy feedstock production systems.

Results showed that relative water content, leaf area, chlorophyll and yield as well as technological properties of barley were improved with chemical inducers application under water surplus and water-stress conditions. Antioxidant enzymes activity (i.e. catalase and peroxidase) were significantly increased in barley grown under water-stress and treated with chemical inducers. Yield and related parameters of barley presented also significant decrease under water-stress treatment, while chemical inducers application enhanced the yield-related traits. Starch and protein contents were higher in plants treated with salicylic acid than in untreated plants when waterstress was applied. In conclusion, results show that chemical inducers application have a positive interaction and synergetic influence and should be suggested to improve plant growth, yield and technological properties of water stressed barley.

Page 215. <br /> <br />Abstract: Digested sludge contains high amounts of phosphorus (P) and nitrogen (N) besides other macro and micronutrients. This study investigated the feasibility of recycling P from sludges originating from three Finnish water purification plants (Viikki, Vaasa, Jyväskylä) and from one dairy farm (Kalmari) into agricultural land by incubating sludges mixed with soil for 90 days. The digestates originating from water purification plants contained different types of waste water precipitation chemicals, whereas that from a dairy farm (Kalmari) contained none. The pH in all soil-sludge mixes decreased during the incubation compared with unfertilized and NPK treated soil. At 0, 30 and 90 days after incubation, the highest concentration of water-extractable or Mehlich-1 soluble P was in soil-Kalmari mix (untreated sludge) followed by the soil-NPK mix, while the lowest soluble P was in unfertilized soil and/or soil-sludge mixes containing precipitation chemicals. The concentration of Al-bound P and the sum of inorganic P fractions were highest in soil-Kalmari mixture. As for the other soil-sludge mixtures, the highest concentration of Al-bound P in soil was found in a mixture containing either Vaasa or Jyväskylä sludge with the highest concentration of Al-Pin the sludge. In addition, the activities of acid- & alkali-phosphatase enzymes increased during the incubation in sludge treated soils relative to unfertilized or NPK treated soil. The increase of P availability in sludge treated soils with time could be attributed to the increasing in the activity of acid-phosphatase, since this enzyme enhances P mineralization by attacking the phosphomonoester bonds of soil organic matter, and thus increasing the P availability for the micro-organisms and plants. The higher amounts of soluble P in soil with Kalmari sludge are more prone to leaching than the less soluble P forms in other sludges containing higher levels of Al or Fe bounded P.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5820f2bf7fff93c6867b425aacafba1b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":38123034,"asset_id":13765748,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/38123034/download_file?st=MTczMjc5MjEzNSw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13765748"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13765748"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13765748; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13765748]").text(description); $(".js-view-count[data-work-id=13765748]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13765748; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13765748']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13765748, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "5820f2bf7fff93c6867b425aacafba1b" } } $('.js-work-strip[data-work-id=13765748]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13765748,"title":"DIGESTED SLUDGES AS A SOURCE OF PHOSPHORUS, AND ENVIRONMENTAL RISK","translated_title":"","metadata":{"abstract":"To cite: SELEIMAN M.F., SIMOJOKI A., SOINNE H., SANTANEN H., MÄKELÄ P.S.A. 2015.

Page 215.\r\n\r\nAbstract: Digested sludge contains high amounts of phosphorus (P) and nitrogen (N) besides other macro and micronutrients. This study investigated the feasibility of recycling P from sludges originating from three Finnish water purification plants (Viikki, Vaasa, Jyväskylä) and from one dairy farm (Kalmari) into agricultural land by incubating sludges mixed with soil for 90 days. The digestates originating from water purification plants contained different types of waste water precipitation chemicals, whereas that from a dairy farm (Kalmari) contained none. The pH in all soil-sludge mixes decreased during the incubation compared with unfertilized and NPK treated soil. At 0, 30 and 90 days after incubation, the highest concentration of water-extractable or Mehlich-1 soluble P was in soil-Kalmari mix (untreated sludge) followed by the soil-NPK mix, while the lowest soluble P was in unfertilized soil and/or soil-sludge mixes containing precipitation chemicals. The concentration of Al-bound P and the sum of inorganic P fractions were highest in soil-Kalmari mixture.

In addition, the activities of acid- \u0026 alkali-phosphatase enzymes increased during the incubation in sludge treated soils relative to unfertilized or NPK treated soil.

أتخيل يوما ما أننى سأكون باحثا متعمقا فى موضوع مثل هذا نظرا لأن رسالة الماجستير الخاصة بى كانت عن موضوع مختلف تماما، ولكن عن مشكلة تعانى منها مصر كدولة وشعبها الأصيل وهى كيفية زيادة إنتاج القمح وتحسين جودة الدقيق والخبز. حيث تعلمون أن إنتاج مصر من القمح لا يتجاوز 7 ملايين طن قمح سنويا فى حين تحتاج مصر سنويا الـ نحو 13 مليون طن قمح لسد احتياجات الشعب المصرى من الخبز وعليه فمصر تستورد نحو 45% من إجمالى ما يحتاجه الشعب المصرى. وفى رسالة الماجستير التى تمت فى الفترة من يناير 2004 وحتى يناير 2007 وفيها تم الحصول على نتائج رائعة فى إنتاج القمح باستخدام أصناف عالية الإنتاج مثل جميزة 9 وجميزة 10 وسخا 93 إضافة إلى زيادة جودة الدقيق وبالتالى الخبز عن طريق زيادة نسبه الجلوتين بالدقيق من خلال تقليل عدد مرات الرى أو زيادة نسبة التسميد النتروجينى. وكانت انتاج الفدان ما يقرب من 25 أردب قمح وقد تم نشر نتائج رسالة الماجستير فى العديد من المجلات الدولية التى لها صدى دولى. وقد حظيتُ بإشراف كل من أستاتذى الأفاضل: الأستاذ الدكتور سيد محمود عبد العال أستاذ المحاصيل ورئيس القسم ووكيل كلية الزراعة بشبين الكوم والأستاذ الدكتور محمود الدسوقى أستاذ المحاصيل ورئيس القسم السابق ورئيس وحدة تسويق البحوث العلمية بالجامعة والأستاذ الدكتور جمال زهران أستاذ الخبز والعجائن بمركز البحوث الزراعية بالقاهرة. وبعد سفرى لفنلندا لتجميع المادة العلمية اللازمة للدكتوراه من جامعة هلسنكى والتى تتربع فى المرتبة رقم 54 عالميا والرابعة أوروبيا. سافرت بالتحديد فى 4 ستمبر 2008 ولمدة تسعة أشهر كانت بداية الطريق للتعمق فى عنوان هذا المقال بعد أن كنت بين خيارين هما: إما أن أكمل موضوع رسالة الدكتوراه التى بدأتها بمصر وهى عن السمسم وفى هذه الحالة سأجلس فى فنلندا تسعة أشهر دون أن أستفيد شيئا، ففنلندا لا تزرع السمسم بحكم بروده طقسها. والخيار الثانى أن أنسى أو أتناسى موضوع السمسم وأن أبدأ فى موضوع جديد يكون له أهمية دولية أكثر. بالفعل اخترت أن أبدأ موضوعا جديدا له أهمية دولية يخدم البشرية بمن فيهم الشعب المصرى وكان عنوان رسالة الدكتوراه عن الاستخدام الآمن لمخلفات الإنسان والحيوان كغذاء لمحاصيل الطاقة الحيوية بدلا من استخدامها كسماد لمحاصيل يتم استخدامها فى غذاء الإنسان أو الحيوان. فمن المعروف أن مخلفات الإنسان والحيوان غنية جدا بأهم العناصر الغذائية كالنتروجين والفسفور والبوتاسيوم إلاّ أنها تحتوى على عناصر ثقيلة كالنحاس والرصاص والزرنيخ والنيكل التى تسبب الفشل الكلوى والسرطان وغيرها من أمراض انتشرت فى مصر نظرا لاستخدام المزارع المصرى هذه المخلفات فى رى الخضروات كالخس والكرنب والمحاصيل الحقليه كقصب السكر والبنجر والقمح والأرز..إلخ. وعليه فإن أفضل استخدام لهذه المخلفات هو استخدامها كغذاء لأى محصول صالح فى إنتاج الطاقة الحيوية. كإنتاج الكهرباء وغاز البيوجاز والبيو ديزل لتشغيل جميع وسائل النقل على أن يتم زراعة مثل هذه المحاصيل فى صحراء مصر التى تقدر بأكثر من 90% من مساحة مصر دون الحاجة إلى ماء أو سماد لنمو هذه المحاصيل. فهذه المحاصيل يمكنها الاعتماد على مياه الصرف الصحى بدلا من صرف هذه المياه فى نهر النيل أو البحر كما يحدث الآن فى مصر. ضف إلى ذلك تعمير الصحراء بمثل هذه المحاصيل وإنتاج كساء خضرى يمنعها من التعرض للتدهور علاوة على ذلك زيادة إنتاج الطاقة الحيوية لتساعد فى سد الفجوة من نقص للكهرباء والبنزين والسولار. والأكثر من هذا فإن هذه المحاصيل ستعمل على زيادة نسبة الأكسجين فى الهواء الذى يتنفسه الإنسان وستقوم بامتصاص غاز ثانى أكسيد الكربون السام من الهواء لاستخدامه فى عملية البناء الضوئى. بل والأهم من هذا كله أنه يمكن إقامة مصانع فى الصحراء كمشاريع استثمارية لاستخلاص الوقود الحيوى من هذه المحاصيل وجزء من هذه الطاقة سيتخدم فى إنارة وتشغيل وسائل النقل فى هذه المناطق وتصدير الباقى إلى محافظات مصر المختلفة. لقد قمت بفضل الله وتوفيقه بنشر العديد من الأبحاث العلمية فى هذا المجال فى مجلات دولية محترمة يصعب النشر فيها وآخر هذه الأبحاث تم نشره أون لاين يوم 5 مارس 2013 بأحد المجلات الدولية التى تنشر بواسطة دار النشر العالمية ).Chemosphere -Impact factor 3.6 (Elsevier <br /> <br />وشاركت بفضل الله فى سبعة مؤتمرات دولية بأبحاث ومحاضرات فى هذه التخصص من بين هذه الدول فرنسا وفنلندا والسويد واليونان ومصر والدنمارك. وقد حصلت على الجائزة الأولى لأفضل بحث فى هذا المجال فى أحد المؤتمرات الدولية بالعاصمة الفنلندية هلسنكى فى عام 2012 بين أكثر من 500 باحث كانوا ينافسون على تلك الجائزة وقد تم تكريمى من إدارة المؤتمر ومن سفير مصر بفنلندا السفير محمد قاسم ومن المستشار الثقافى بألمانيا الأستاذ الدكتور ممدوح الدماطى. وسيكون لنا لقاء عن فكرة كل بحث من هذه الأبحاث فى مقالات أخرى إن شاء الله. <br /> <br />بقلم د محمود فتحى سليمان <br /> <br />العلوم الزراعية – جامعه هلسنكى –

مختلف تماما، ولكن عن مشكلة تعانى منها مصر كدولة وشعبها الأصيل وهى كيفية زيادة إنتاج القمح وتحسين جودة الدقيق والخبز. حيث تعلمون أن إنتاج مصر من القمح لا يتجاوز 7 ملايين طن قمح سنويا فى حين تحتاج مصر سنويا الـ نحو 13 مليون طن قمح لسد احتياجات الشعب المصرى من الخبز وعليه فمصر تستورد نحو 45% من إجمالى ما يحتاجه الشعب المصرى. وفى رسالة الماجستير التى تمت فى الفترة من يناير 2004 وحتى يناير 2007 وفيها تم الحصول على نتائج رائعة فى إنتاج القمح باستخدام أصناف عالية الإنتاج مثل جميزة 9 وجميزة 10 وسخا 93 إضافة إلى زيادة جودة الدقيق وبالتالى الخبز عن طريق زيادة نسبه الجلوتين بالدقيق من خلال تقليل عدد مرات الرى أو زيادة نسبة التسميد النتروجينى. وكانت انتاج الفدان ما يقرب من 25 أردب قمح وقد تم نشر نتائج رسالة الماجستير فى العديد من المجلات الدولية التى لها صدى دولى. وقد حظيتُ بإشراف كل من أستاتذى الأفاضل: الأستاذ الدكتور سيد محمود عبد العال أستاذ المحاصيل ورئيس القسم ووكيل كلية الزراعة بشبين الكوم والأستاذ الدكتور محمود الدسوقى أستاذ المحاصيل ورئيس القسم السابق ورئيس وحدة تسويق البحوث العلمية بالجامعة والأستاذ الدكتور جمال زهران أستاذ الخبز والعجائن بمركز البحوث الزراعية بالقاهرة. وبعد سفرى لفنلندا لتجميع المادة العلمية اللازمة للدكتوراه من جامعة هلسنكى والتى تتربع فى المرتبة رقم 54 عالميا والرابعة أوروبيا. سافرت بالتحديد فى 4 ستمبر 2008 ولمدة تسعة أشهر كانت بداية الطريق للتعمق فى عنوان هذا المقال بعد أن كنت بين خيارين هما: إما أن أكمل موضوع رسالة الدكتوراه التى بدأتها بمصر وهى عن السمسم وفى هذه الحالة سأجلس فى فنلندا تسعة أشهر دون أن أستفيد شيئا، ففنلندا لا تزرع السمسم بحكم بروده طقسها. والخيار الثانى أن أنسى أو أتناسى موضوع السمسم وأن أبدأ فى موضوع جديد يكون له أهمية دولية أكثر. بالفعل اخترت أن أبدأ موضوعا جديدا له أهمية دولية يخدم البشرية بمن فيهم الشعب المصرى وكان عنوان رسالة الدكتوراه عن الاستخدام الآمن لمخلفات الإنسان والحيوان كغذاء لمحاصيل الطاقة الحيوية بدلا من استخدامها كسماد لمحاصيل يتم استخدامها فى غذاء الإنسان أو الحيوان. فمن المعروف أن مخلفات الإنسان والحيوان غنية جدا بأهم العناصر الغذائية كالنتروجين والفسفور والبوتاسيوم إلاّ أنها تحتوى على عناصر ثقيلة كالنحاس والرصاص والزرنيخ والنيكل التى تسبب الفشل الكلوى والسرطان وغيرها من أمراض انتشرت فى مصر نظرا لاستخدام المزارع المصرى هذه المخلفات فى رى الخضروات كالخس والكرنب والمحاصيل الحقليه كقصب السكر والبنجر والقمح والأرز..إلخ. وعليه فإن أفضل استخدام لهذه المخلفات هو استخدامها كغذاء لأى محصول صالح فى إنتاج الطاقة الحيوية. كإنتاج الكهرباء وغاز البيوجاز والبيو ديزل لتشغيل جميع وسائل النقل على أن يتم زراعة مثل هذه المحاصيل فى صحراء مصر التى تقدر بأكثر من 90% من مساحة مصر دون الحاجة إلى ماء أو سماد لنمو هذه المحاصيل. فهذه المحاصيل يمكنها الاعتماد على مياه الصرف الصحى بدلا من صرف هذه المياه فى نهر

والبنزين والسولار. والأكثر من هذا فإن هذه المحاصيل ستعمل على زيادة نسبة الأكسجين فى الهواء الذى يتنفسه الإنسان وستقوم بامتصاص غاز ثانى أكسيد الكربون السام من الهواء لاستخدامه فى عملية البناء الضوئى. بل والأهم من هذا كله أنه يمكن إقامة مصانع فى الصحراء كمشاريع استثمارية لاستخلاص الوقود الحيوى من هذه المحاصيل وجزء من هذه الطاقة سيتخدم فى إنارة وتشغيل وسائل النقل فى هذه المناطق وتصدير الباقى إلى محافظات مصر المختلفة. لقد قمت بفضل الله وتوفيقه بنشر العديد من الأبحاث العلمية فى هذا المجال فى مجلات دولية محترمة يصعب النشر فيها وآخر هذه الأبحاث تم نشره أون لاين يوم 5 مارس 2013 بأحد المجلات

The sludge–peat mix increased significantly leaf area and biomass accumulation of maize and hemp. High sludge and sludge–peat mix applications increased significantly the leaf area and biomass accumulation as well as the net photosynthesis of oilseed rape. High sludge application resulted in the highest heavy metal and metalloid accumulation in maize and hemp. Sludge–peat mix resulted in the highest heavy metal and metalloid accumulation in oilseed rape. However, the sludge–peat mix application provided the best feedstock quality in all three crops, since chloride, silicon and sulfur concentrations and ash content in plant material were the lowest of the three sludge treatments.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="de7a99b5798152360aff342eb68613cc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":36367279,"asset_id":4352709,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/36367279/download_file?st=MTczMjc5MjEzNSw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="4352709"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="4352709"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 4352709; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=4352709]").text(description); $(".js-view-count[data-work-id=4352709]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 4352709; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='4352709']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 4352709, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "de7a99b5798152360aff342eb68613cc" } } $('.js-work-strip[data-work-id=4352709]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":4352709,"title":"Feedstock quality and growth of bioenergy crops fertilized with sewage sludge- Chemosphere Journal, Volume 89, Issue 10, November 2012, Pages 1211–1217","translated_title":"","metadata":{"abstract":"\r\nSewage sludge is rich in essential plant nutrients, but its use is restricted for crop production due to the pollutants it contains, such as metalloids and heavy metals.

It also improves the soil conditions and plant nutrition through colonization by mycorrhizal fungi as well as reducing leaching and need of synthetic fertilizers.\r\n","internal_url":"https://www.academia.edu/4352638/Improved_sustainability_of_feedstock_production_with_sludge_and_interacting_mycorrhiza_Chemosphere_Journal_Volume_91_Issue_9_May_2013_Pages_1236_1242","translated_internal_url":"","created_at":"2013-08-28T09:17:28.104-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":167466,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":36367294,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/36367294/thumbnails/1.jpg","file_name":"2_Improved_sustainability_of_feedstock_production_with_sludge.pdf","download_url":"https://www.academia.edu/attachments/36367294/download_file?st=MTczMjc5MjEzNSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Improved_sustainability_of_feedstock_pro.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/36367294/2_Improved_sustainability_of_feedstock_production_with_sludge-libre.pdf?1421970645=\u0026response-content-disposition=attachment%3B+filename%3DImproved_sustainability_of_feedstock_pro.pdf\u0026Expires=1732726388\u0026Signature=QTcystP1HAarjbHfj5eK9mG~RRJledt2pSIloD6~YTGWzwTvXaRQnn-l9WuL6BePtX3B8xVtPDDj3Fg-vCGWM5g6zXp5tZguAa6-EI2i9pLD~avM-eHsfDQ4gushaXK65b-~B-wXq~pOq~q7U88UosNB9Y3lRLN2~VK1TT-Nz8Bn2-GHhX59Svg18GPO2gbYeKRj4otHXqpdFmDc-ioejGcgOn1zWvCosp1o0PKZD5xWajdTwZT-tDjrgw7~lSZhqnM3LCh~Sj~pwm3WplrZlmMjiKMGmlTeTeFMM1clESTH5-Btyb3k~aj97DxDYY5EpJaW2xZ~AY9hXDeCXl~TQg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Improved_sustainability_of_feedstock_production_with_sludge_and_interacting_mycorrhiza_Chemosphere_Journal_Volume_91_Issue_9_May_2013_Pages_1236_1242","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":167466,"first_name":"Dr. Mahmoud Fathy","middle_initials":"","last_name":"Seleiman","page_name":"MahmoudFathySeleiman","domain_name":"helsinki","created_at":"2010-04-10T20:50:16.866-07:00","display_name":"Dr. Mahmoud Fathy Seleiman","url":"https://helsinki.academia.edu/MahmoudFathySeleiman"},"attachments":[{"id":36367294,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/36367294/thumbnails/1.jpg","file_name":"2_Improved_sustainability_of_feedstock_production_with_sludge.pdf","download_url":"https://www.academia.edu/attachments/36367294/download_file?st=MTczMjc5MjEzNSw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Improved_sustainability_of_feedstock_pro.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/36367294/2_Improved_sustainability_of_feedstock_production_with_sludge-libre.pdf?1421970645=\u0026response-content-disposition=attachment%3B+filename%3DImproved_sustainability_of_feedstock_pro.pdf\u0026Expires=1732726388\u0026Signature=QTcystP1HAarjbHfj5eK9mG~RRJledt2pSIloD6~YTGWzwTvXaRQnn-l9WuL6BePtX3B8xVtPDDj3Fg-vCGWM5g6zXp5tZguAa6-EI2i9pLD~avM-eHsfDQ4gushaXK65b-~B-wXq~pOq~q7U88UosNB9Y3lRLN2~VK1TT-Nz8Bn2-GHhX59Svg18GPO2gbYeKRj4otHXqpdFmDc-ioejGcgOn1zWvCosp1o0PKZD5xWajdTwZT-tDjrgw7~lSZhqnM3LCh~Sj~pwm3WplrZlmMjiKMGmlTeTeFMM1clESTH5-Btyb3k~aj97DxDYY5EpJaW2xZ~AY9hXDeCXl~TQg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":57697,"name":"Heavy metals","url":"https://www.academia.edu/Documents/in/Heavy_metals"},{"id":67661,"name":"Sewage sludge","url":"https://www.academia.edu/Documents/in/Sewage_sludge"},{"id":592629,"name":"Mycorrhizae","url":"https://www.academia.edu/Documents/in/Mycorrhizae"},{"id":820159,"name":"Bioenergy Crops","url":"https://www.academia.edu/Documents/in/Bioenergy_Crops"}],"urls":[{"id":1518619,"url":"http://www.sciencedirect.com/science/article/pii/S0045653513002725"}]}, dispatcherData: dispatcherData });

Therefore, a three-year field experiment was conducted to investigate the suitability of sewage and digested sludge in comparison to synthetic fertilizer on biomass production and its quality in three crop species, with specific attention to the relationship between N availability and biomass accumulation. Fertilizer treatments for each crop species were standardized on the basis of total Nitrogen as follows: maize 120 kg ha−1, fibre hemp 60 kg ha−1 and oilseed rape 90 kg ha−1 Nitrogen. The highest biomass yield of maize (30 Mg ha−1 Dry Mass) and hemp (15 Mg ha−1 Dry Mass) was obtained from the sewage sludge treatment. The sludge treatment also gave the highest leaf Nitrogen mass in biomass of both maize (14 g kg−1) and hemp (18 g kg−1) at 60 DAS (flowering stage). Sewage sludge increased slightly gross energy yield of maize (438 GJ ha−1) and hemp (272 GJ ha−1) in comparison to other treatments. The mass fraction of ash and the combustion-relevant elements such as Chlorine, Potassium, Sodium and Calcium were lower in crops fertilized with sewage sludge than in those fertilized with synthetic fertilizer.

A combination of morpho-physiological and biochemical parameters and multivariate analysis was used to detect salt tolerance variation in 15 wheat lines developed by doubled haploid (DHL) technique. They were then compared with the salt-tolerant check cultivar Sakha 93. Salinity stress was investigated at three salinity levels (0, 100, and 200 mM NaCl) for 25 days. Considerable genetic variation was observed for all traits, as was high heritability (>60%) and genetic gain (>20%). Principal component analysis indicated the ability of nine traits (root number, root length, root dry weight, shoot length, shoot dry weight, specific root length, relative water content, membrane stability index, and catalase) to identify differences in salinity tolerance among lines. Three traits (shoot length, shoot dry weight, and catalase) were indicative of salt-tolerance, indicating their importance in improving and evaluating salt tolerant genotypes for breeding programs. The salinity tolerance membership index based on these three traits classified one new line (DHL21) and the check cultivar (Sakha 93) as highly salt-tolerant, DHL25, DHL26, DHL2, DHL11, and DHL5 as tolerant, and DHL23 and DHL12 as intermediate.

Thus, it is important to\r\nrecognize that weed control is complex, and that basic\r\nprinciples should be utilized for maximum effectiveness in\r\ncombating weeds.","internal_url":"https://www.academia.edu/323466/Basic_guide_to_weeds_and_herbicides","translated_internal_url":"","created_at":"2010-09-10T21:19:01.416-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":167466,"coauthors_can_edit":true,"document_type":"book","co_author_tags":[],"downloadable_attachments":[{"id":1604765,"title":"Basic guide to weeds and herbicides","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/1604765/thumbnails/1.jpg","file_name":"basic_guide_to_weeds_and_herbicides.pdf","download_url":"https://www.academia.edu/attachments/1604765/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Basic_guide_to_weeds_and_herbicides.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/1604765/basic_guide_to_weeds_and_herbicides-libre.pdf?1390821462=\u0026response-content-disposition=attachment%3B+filename%3DBasic_guide_to_weeds_and_herbicides.pdf\u0026Expires=1732726387\u0026Signature=c9c2hwsoY8tVmW87e5RjJcaVi4WIoZmUXZTy6F39PskkHh8pKH6Iye7j4Vd3QvijyKmwsnA09qkbepI9PD~X98zm-jE9KUZW20Gjz4DDpBxCQXl00cwVAhB1EBOzb3~JaX5T2uuVRqzghQFLHs7NBGuI9foEeMGjLcH4te5Wgf9Qnf5D-OMttRse3tlZVei7s6eJtBiVD4H7~iMeEGPwNtCSICW4h-u~hy01lY-Rv6m3giTo0CJDOvEkwQofGn2dGCzWnPN093K7ONUQdcTbmwVfg-oSqd9JAnzcZrZFrNob9m0PqTRzJqx9sxtyGH5M3SXVqFDbRftsiTdrkPYC3w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Basic_guide_to_weeds_and_herbicides","translated_slug":"","page_count":25,"language":"en","content_type":"Work","owner":{"id":167466,"first_name":"Dr. Mahmoud Fathy","middle_initials":"","last_name":"Seleiman","page_name":"MahmoudFathySeleiman","domain_name":"helsinki","created_at":"2010-04-10T20:50:16.866-07:00","display_name":"Dr. Mahmoud Fathy Seleiman","url":"https://helsinki.academia.edu/MahmoudFathySeleiman"},"attachments":[{"id":1604765,"title":"Basic guide to weeds and herbicides","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/1604765/thumbnails/1.jpg","file_name":"basic_guide_to_weeds_and_herbicides.pdf","download_url":"https://www.academia.edu/attachments/1604765/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Basic_guide_to_weeds_and_herbicides.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/1604765/basic_guide_to_weeds_and_herbicides-libre.pdf?1390821462=\u0026response-content-disposition=attachment%3B+filename%3DBasic_guide_to_weeds_and_herbicides.pdf\u0026Expires=1732726387\u0026Signature=c9c2hwsoY8tVmW87e5RjJcaVi4WIoZmUXZTy6F39PskkHh8pKH6Iye7j4Vd3QvijyKmwsnA09qkbepI9PD~X98zm-jE9KUZW20Gjz4DDpBxCQXl00cwVAhB1EBOzb3~JaX5T2uuVRqzghQFLHs7NBGuI9foEeMGjLcH4te5Wgf9Qnf5D-OMttRse3tlZVei7s6eJtBiVD4H7~iMeEGPwNtCSICW4h-u~hy01lY-Rv6m3giTo0CJDOvEkwQofGn2dGCzWnPN093K7ONUQdcTbmwVfg-oSqd9JAnzcZrZFrNob9m0PqTRzJqx9sxtyGH5M3SXVqFDbRftsiTdrkPYC3w__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[],"urls":[]}, dispatcherData: dispatcherData }); $(this).data('initialized', true); } }); $a.trackClickSource(".js-work-strip-work-link", "profile_work_strip") }); </script> </div><div class="profile--tab_content_container js-tab-pane tab-pane" data-section-id="16687" id="papers"><div class="js-work-strip profile--work_container" data-work-id="43019986"><div class="profile--work_thumbnail hidden-xs"><a class="js-work-strip-work-link" data-click-track="profile-work-strip-thumbnail" href="https://www.academia.edu/43019986/WILL_NOVEL_CORONAVIRUS_COVID_19_PANDEMIC_IMPACT_AGRICULTURE_FOOD_SECURITY_AND_ANIMAL_SECTORS_QUAL_SER%C3%81_O_IMPACTO_DA_PANDEMIA_DO_NOVO_CORONAVIRUS_COVID_19_NA_AGRICULTURA_SEGURAN%C3%87A_ALIMENTAR_E_SETORES_DE_PRODU%C3%87%C3%83O_ANIMAL"><img alt="Research paper thumbnail of WILL NOVEL CORONAVIRUS (COVID-19) PANDEMIC IMPACT AGRICULTURE, FOOD SECURITY AND ANIMAL SECTORS?

Results showed that relative water content, leaf area, chlorophyll and yield as well as technological properties of barley were improved with chemical inducers application under water surplus and water-stress conditions. Antioxidant enzymes activity (i.e. catalase and peroxidase) were significantly increased in barley grown under water-stress and treated with chemical inducers. Yield and related parameters of barley presented also significant decrease under water-stress treatment, while chemical inducers application enhanced the yield-related traits. Starch and protein contents were higher in plants treated with salicylic acid than in untreated plants when waterstress was applied. In conclusion, results show that chemical inducers application have a positive interaction and synergetic influence and should be suggested to improve plant growth, yield and technological properties of water stressed barley.

Page 215. <br /> <br />Abstract: Digested sludge contains high amounts of phosphorus (P) and nitrogen (N) besides other macro and micronutrients. This study investigated the feasibility of recycling P from sludges originating from three Finnish water purification plants (Viikki, Vaasa, Jyväskylä) and from one dairy farm (Kalmari) into agricultural land by incubating sludges mixed with soil for 90 days. The digestates originating from water purification plants contained different types of waste water precipitation chemicals, whereas that from a dairy farm (Kalmari) contained none. The pH in all soil-sludge mixes decreased during the incubation compared with unfertilized and NPK treated soil. At 0, 30 and 90 days after incubation, the highest concentration of water-extractable or Mehlich-1 soluble P was in soil-Kalmari mix (untreated sludge) followed by the soil-NPK mix, while the lowest soluble P was in unfertilized soil and/or soil-sludge mixes containing precipitation chemicals. The concentration of Al-bound P and the sum of inorganic P fractions were highest in soil-Kalmari mixture. As for the other soil-sludge mixtures, the highest concentration of Al-bound P in soil was found in a mixture containing either Vaasa or Jyväskylä sludge with the highest concentration of Al-Pin the sludge. In addition, the activities of acid- & alkali-phosphatase enzymes increased during the incubation in sludge treated soils relative to unfertilized or NPK treated soil. The increase of P availability in sludge treated soils with time could be attributed to the increasing in the activity of acid-phosphatase, since this enzyme enhances P mineralization by attacking the phosphomonoester bonds of soil organic matter, and thus increasing the P availability for the micro-organisms and plants. The higher amounts of soluble P in soil with Kalmari sludge are more prone to leaching than the less soluble P forms in other sludges containing higher levels of Al or Fe bounded P.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="5820f2bf7fff93c6867b425aacafba1b" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":38123034,"asset_id":13765748,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/38123034/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="13765748"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="13765748"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 13765748; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=13765748]").text(description); $(".js-view-count[data-work-id=13765748]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 13765748; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='13765748']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 13765748, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "5820f2bf7fff93c6867b425aacafba1b" } } $('.js-work-strip[data-work-id=13765748]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":13765748,"title":"DIGESTED SLUDGES AS A SOURCE OF PHOSPHORUS, AND ENVIRONMENTAL RISK","translated_title":"","metadata":{"abstract":"To cite: SELEIMAN M.F., SIMOJOKI A., SOINNE H., SANTANEN H., MÄKELÄ P.S.A. 2015.

Page 215.\r\n\r\nAbstract: Digested sludge contains high amounts of phosphorus (P) and nitrogen (N) besides other macro and micronutrients. This study investigated the feasibility of recycling P from sludges originating from three Finnish water purification plants (Viikki, Vaasa, Jyväskylä) and from one dairy farm (Kalmari) into agricultural land by incubating sludges mixed with soil for 90 days. The digestates originating from water purification plants contained different types of waste water precipitation chemicals, whereas that from a dairy farm (Kalmari) contained none. The pH in all soil-sludge mixes decreased during the incubation compared with unfertilized and NPK treated soil. At 0, 30 and 90 days after incubation, the highest concentration of water-extractable or Mehlich-1 soluble P was in soil-Kalmari mix (untreated sludge) followed by the soil-NPK mix, while the lowest soluble P was in unfertilized soil and/or soil-sludge mixes containing precipitation chemicals. The concentration of Al-bound P and the sum of inorganic P fractions were highest in soil-Kalmari mixture.

In addition, the activities of acid- \u0026 alkali-phosphatase enzymes increased during the incubation in sludge treated soils relative to unfertilized or NPK treated soil.

أتخيل يوما ما أننى سأكون باحثا متعمقا فى موضوع مثل هذا نظرا لأن رسالة الماجستير الخاصة بى كانت عن موضوع مختلف تماما، ولكن عن مشكلة تعانى منها مصر كدولة وشعبها الأصيل وهى كيفية زيادة إنتاج القمح وتحسين جودة الدقيق والخبز. حيث تعلمون أن إنتاج مصر من القمح لا يتجاوز 7 ملايين طن قمح سنويا فى حين تحتاج مصر سنويا الـ نحو 13 مليون طن قمح لسد احتياجات الشعب المصرى من الخبز وعليه فمصر تستورد نحو 45% من إجمالى ما يحتاجه الشعب المصرى. وفى رسالة الماجستير التى تمت فى الفترة من يناير 2004 وحتى يناير 2007 وفيها تم الحصول على نتائج رائعة فى إنتاج القمح باستخدام أصناف عالية الإنتاج مثل جميزة 9 وجميزة 10 وسخا 93 إضافة إلى زيادة جودة الدقيق وبالتالى الخبز عن طريق زيادة نسبه الجلوتين بالدقيق من خلال تقليل عدد مرات الرى أو زيادة نسبة التسميد النتروجينى. وكانت انتاج الفدان ما يقرب من 25 أردب قمح وقد تم نشر نتائج رسالة الماجستير فى العديد من المجلات الدولية التى لها صدى دولى. وقد حظيتُ بإشراف كل من أستاتذى الأفاضل: الأستاذ الدكتور سيد محمود عبد العال أستاذ المحاصيل ورئيس القسم ووكيل كلية الزراعة بشبين الكوم والأستاذ الدكتور محمود الدسوقى أستاذ المحاصيل ورئيس القسم السابق ورئيس وحدة تسويق البحوث العلمية بالجامعة والأستاذ الدكتور جمال زهران أستاذ الخبز والعجائن بمركز البحوث الزراعية بالقاهرة. وبعد سفرى لفنلندا لتجميع المادة العلمية اللازمة للدكتوراه من جامعة هلسنكى والتى تتربع فى المرتبة رقم 54 عالميا والرابعة أوروبيا. سافرت بالتحديد فى 4 ستمبر 2008 ولمدة تسعة أشهر كانت بداية الطريق للتعمق فى عنوان هذا المقال بعد أن كنت بين خيارين هما: إما أن أكمل موضوع رسالة الدكتوراه التى بدأتها بمصر وهى عن السمسم وفى هذه الحالة سأجلس فى فنلندا تسعة أشهر دون أن أستفيد شيئا، ففنلندا لا تزرع السمسم بحكم بروده طقسها. والخيار الثانى أن أنسى أو أتناسى موضوع السمسم وأن أبدأ فى موضوع جديد يكون له أهمية دولية أكثر. بالفعل اخترت أن أبدأ موضوعا جديدا له أهمية دولية يخدم البشرية بمن فيهم الشعب المصرى وكان عنوان رسالة الدكتوراه عن الاستخدام الآمن لمخلفات الإنسان والحيوان كغذاء لمحاصيل الطاقة الحيوية بدلا من استخدامها كسماد لمحاصيل يتم استخدامها فى غذاء الإنسان أو الحيوان. فمن المعروف أن مخلفات الإنسان والحيوان غنية جدا بأهم العناصر الغذائية كالنتروجين والفسفور والبوتاسيوم إلاّ أنها تحتوى على عناصر ثقيلة كالنحاس والرصاص والزرنيخ والنيكل التى تسبب الفشل الكلوى والسرطان وغيرها من أمراض انتشرت فى مصر نظرا لاستخدام المزارع المصرى هذه المخلفات فى رى الخضروات كالخس والكرنب والمحاصيل الحقليه كقصب السكر والبنجر والقمح والأرز..إلخ. وعليه فإن أفضل استخدام لهذه المخلفات هو استخدامها كغذاء لأى محصول صالح فى إنتاج الطاقة الحيوية. كإنتاج الكهرباء وغاز البيوجاز والبيو ديزل لتشغيل جميع وسائل النقل على أن يتم زراعة مثل هذه المحاصيل فى صحراء مصر التى تقدر بأكثر من 90% من مساحة مصر دون الحاجة إلى ماء أو سماد لنمو هذه المحاصيل. فهذه المحاصيل يمكنها الاعتماد على مياه الصرف الصحى بدلا من صرف هذه المياه فى نهر النيل أو البحر كما يحدث الآن فى مصر. ضف إلى ذلك تعمير الصحراء بمثل هذه المحاصيل وإنتاج كساء خضرى يمنعها من التعرض للتدهور علاوة على ذلك زيادة إنتاج الطاقة الحيوية لتساعد فى سد الفجوة من نقص للكهرباء والبنزين والسولار. والأكثر من هذا فإن هذه المحاصيل ستعمل على زيادة نسبة الأكسجين فى الهواء الذى يتنفسه الإنسان وستقوم بامتصاص غاز ثانى أكسيد الكربون السام من الهواء لاستخدامه فى عملية البناء الضوئى. بل والأهم من هذا كله أنه يمكن إقامة مصانع فى الصحراء كمشاريع استثمارية لاستخلاص الوقود الحيوى من هذه المحاصيل وجزء من هذه الطاقة سيتخدم فى إنارة وتشغيل وسائل النقل فى هذه المناطق وتصدير الباقى إلى محافظات مصر المختلفة. لقد قمت بفضل الله وتوفيقه بنشر العديد من الأبحاث العلمية فى هذا المجال فى مجلات دولية محترمة يصعب النشر فيها وآخر هذه الأبحاث تم نشره أون لاين يوم 5 مارس 2013 بأحد المجلات الدولية التى تنشر بواسطة دار النشر العالمية ).Chemosphere -Impact factor 3.6 (Elsevier <br /> <br />وشاركت بفضل الله فى سبعة مؤتمرات دولية بأبحاث ومحاضرات فى هذه التخصص من بين هذه الدول فرنسا وفنلندا والسويد واليونان ومصر والدنمارك. وقد حصلت على الجائزة الأولى لأفضل بحث فى هذا المجال فى أحد المؤتمرات الدولية بالعاصمة الفنلندية هلسنكى فى عام 2012 بين أكثر من 500 باحث كانوا ينافسون على تلك الجائزة وقد تم تكريمى من إدارة المؤتمر ومن سفير مصر بفنلندا السفير محمد قاسم ومن المستشار الثقافى بألمانيا الأستاذ الدكتور ممدوح الدماطى. وسيكون لنا لقاء عن فكرة كل بحث من هذه الأبحاث فى مقالات أخرى إن شاء الله. <br /> <br />بقلم د محمود فتحى سليمان <br /> <br />العلوم الزراعية – جامعه هلسنكى –

مختلف تماما، ولكن عن مشكلة تعانى منها مصر كدولة وشعبها الأصيل وهى كيفية زيادة إنتاج القمح وتحسين جودة الدقيق والخبز. حيث تعلمون أن إنتاج مصر من القمح لا يتجاوز 7 ملايين طن قمح سنويا فى حين تحتاج مصر سنويا الـ نحو 13 مليون طن قمح لسد احتياجات الشعب المصرى من الخبز وعليه فمصر تستورد نحو 45% من إجمالى ما يحتاجه الشعب المصرى. وفى رسالة الماجستير التى تمت فى الفترة من يناير 2004 وحتى يناير 2007 وفيها تم الحصول على نتائج رائعة فى إنتاج القمح باستخدام أصناف عالية الإنتاج مثل جميزة 9 وجميزة 10 وسخا 93 إضافة إلى زيادة جودة الدقيق وبالتالى الخبز عن طريق زيادة نسبه الجلوتين بالدقيق من خلال تقليل عدد مرات الرى أو زيادة نسبة التسميد النتروجينى. وكانت انتاج الفدان ما يقرب من 25 أردب قمح وقد تم نشر نتائج رسالة الماجستير فى العديد من المجلات الدولية التى لها صدى دولى. وقد حظيتُ بإشراف كل من أستاتذى الأفاضل: الأستاذ الدكتور سيد محمود عبد العال أستاذ المحاصيل ورئيس القسم ووكيل كلية الزراعة بشبين الكوم والأستاذ الدكتور محمود الدسوقى أستاذ المحاصيل ورئيس القسم السابق ورئيس وحدة تسويق البحوث العلمية بالجامعة والأستاذ الدكتور جمال زهران أستاذ الخبز والعجائن بمركز البحوث الزراعية بالقاهرة. وبعد سفرى لفنلندا لتجميع المادة العلمية اللازمة للدكتوراه من جامعة هلسنكى والتى تتربع فى المرتبة رقم 54 عالميا والرابعة أوروبيا. سافرت بالتحديد فى 4 ستمبر 2008 ولمدة تسعة أشهر كانت بداية الطريق للتعمق فى عنوان هذا المقال بعد أن كنت بين خيارين هما: إما أن أكمل موضوع رسالة الدكتوراه التى بدأتها بمصر وهى عن السمسم وفى هذه الحالة سأجلس فى فنلندا تسعة أشهر دون أن أستفيد شيئا، ففنلندا لا تزرع السمسم بحكم بروده طقسها. والخيار الثانى أن أنسى أو أتناسى موضوع السمسم وأن أبدأ فى موضوع جديد يكون له أهمية دولية أكثر. بالفعل اخترت أن أبدأ موضوعا جديدا له أهمية دولية يخدم البشرية بمن فيهم الشعب المصرى وكان عنوان رسالة الدكتوراه عن الاستخدام الآمن لمخلفات الإنسان والحيوان كغذاء لمحاصيل الطاقة الحيوية بدلا من استخدامها كسماد لمحاصيل يتم استخدامها فى غذاء الإنسان أو الحيوان. فمن المعروف أن مخلفات الإنسان والحيوان غنية جدا بأهم العناصر الغذائية كالنتروجين والفسفور والبوتاسيوم إلاّ أنها تحتوى على عناصر ثقيلة كالنحاس والرصاص والزرنيخ والنيكل التى تسبب الفشل الكلوى والسرطان وغيرها من أمراض انتشرت فى مصر نظرا لاستخدام المزارع المصرى هذه المخلفات فى رى الخضروات كالخس والكرنب والمحاصيل الحقليه كقصب السكر والبنجر والقمح والأرز..إلخ. وعليه فإن أفضل استخدام لهذه المخلفات هو استخدامها كغذاء لأى محصول صالح فى إنتاج الطاقة الحيوية. كإنتاج الكهرباء وغاز البيوجاز والبيو ديزل لتشغيل جميع وسائل النقل على أن يتم زراعة مثل هذه المحاصيل فى صحراء مصر التى تقدر بأكثر من 90% من مساحة مصر دون الحاجة إلى ماء أو سماد لنمو هذه المحاصيل. فهذه المحاصيل يمكنها الاعتماد على مياه الصرف الصحى بدلا من صرف هذه المياه فى نهر

والبنزين والسولار. والأكثر من هذا فإن هذه المحاصيل ستعمل على زيادة نسبة الأكسجين فى الهواء الذى يتنفسه الإنسان وستقوم بامتصاص غاز ثانى أكسيد الكربون السام من الهواء لاستخدامه فى عملية البناء الضوئى. بل والأهم من هذا كله أنه يمكن إقامة مصانع فى الصحراء كمشاريع استثمارية لاستخلاص الوقود الحيوى من هذه المحاصيل وجزء من هذه الطاقة سيتخدم فى إنارة وتشغيل وسائل النقل فى هذه المناطق وتصدير الباقى إلى محافظات مصر المختلفة. لقد قمت بفضل الله وتوفيقه بنشر العديد من الأبحاث العلمية فى هذا المجال فى مجلات دولية محترمة يصعب النشر فيها وآخر هذه الأبحاث تم نشره أون لاين يوم 5 مارس 2013 بأحد المجلات

The sludge–peat mix increased significantly leaf area and biomass accumulation of maize and hemp. High sludge and sludge–peat mix applications increased significantly the leaf area and biomass accumulation as well as the net photosynthesis of oilseed rape. High sludge application resulted in the highest heavy metal and metalloid accumulation in maize and hemp. Sludge–peat mix resulted in the highest heavy metal and metalloid accumulation in oilseed rape. However, the sludge–peat mix application provided the best feedstock quality in all three crops, since chloride, silicon and sulfur concentrations and ash content in plant material were the lowest of the three sludge treatments.</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="de7a99b5798152360aff342eb68613cc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":36367279,"asset_id":4352709,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/36367279/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="4352709"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="4352709"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 4352709; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=4352709]").text(description); $(".js-view-count[data-work-id=4352709]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 4352709; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='4352709']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 4352709, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "de7a99b5798152360aff342eb68613cc" } } $('.js-work-strip[data-work-id=4352709]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":4352709,"title":"Feedstock quality and growth of bioenergy crops fertilized with sewage sludge- Chemosphere Journal, Volume 89, Issue 10, November 2012, Pages 1211–1217","translated_title":"","metadata":{"abstract":"\r\nSewage sludge is rich in essential plant nutrients, but its use is restricted for crop production due to the pollutants it contains, such as metalloids and heavy metals.

It also improves the soil conditions and plant nutrition through colonization by mycorrhizal fungi as well as reducing leaching and need of synthetic fertilizers.\r\n","internal_url":"https://www.academia.edu/4352638/Improved_sustainability_of_feedstock_production_with_sludge_and_interacting_mycorrhiza_Chemosphere_Journal_Volume_91_Issue_9_May_2013_Pages_1236_1242","translated_internal_url":"","created_at":"2013-08-28T09:17:28.104-07:00","preview_url":null,"current_user_can_edit":null,"current_user_is_owner":null,"owner_id":167466,"coauthors_can_edit":true,"document_type":"paper","co_author_tags":[],"downloadable_attachments":[{"id":36367294,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/36367294/thumbnails/1.jpg","file_name":"2_Improved_sustainability_of_feedstock_production_with_sludge.pdf","download_url":"https://www.academia.edu/attachments/36367294/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Improved_sustainability_of_feedstock_pro.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/36367294/2_Improved_sustainability_of_feedstock_production_with_sludge-libre.pdf?1421970645=\u0026response-content-disposition=attachment%3B+filename%3DImproved_sustainability_of_feedstock_pro.pdf\u0026Expires=1732726388\u0026Signature=QTcystP1HAarjbHfj5eK9mG~RRJledt2pSIloD6~YTGWzwTvXaRQnn-l9WuL6BePtX3B8xVtPDDj3Fg-vCGWM5g6zXp5tZguAa6-EI2i9pLD~avM-eHsfDQ4gushaXK65b-~B-wXq~pOq~q7U88UosNB9Y3lRLN2~VK1TT-Nz8Bn2-GHhX59Svg18GPO2gbYeKRj4otHXqpdFmDc-ioejGcgOn1zWvCosp1o0PKZD5xWajdTwZT-tDjrgw7~lSZhqnM3LCh~Sj~pwm3WplrZlmMjiKMGmlTeTeFMM1clESTH5-Btyb3k~aj97DxDYY5EpJaW2xZ~AY9hXDeCXl~TQg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"slug":"Improved_sustainability_of_feedstock_production_with_sludge_and_interacting_mycorrhiza_Chemosphere_Journal_Volume_91_Issue_9_May_2013_Pages_1236_1242","translated_slug":"","page_count":8,"language":"en","content_type":"Work","owner":{"id":167466,"first_name":"Dr. Mahmoud Fathy","middle_initials":"","last_name":"Seleiman","page_name":"MahmoudFathySeleiman","domain_name":"helsinki","created_at":"2010-04-10T20:50:16.866-07:00","display_name":"Dr. Mahmoud Fathy Seleiman","url":"https://helsinki.academia.edu/MahmoudFathySeleiman"},"attachments":[{"id":36367294,"title":"","file_type":"pdf","scribd_thumbnail_url":"https://attachments.academia-assets.com/36367294/thumbnails/1.jpg","file_name":"2_Improved_sustainability_of_feedstock_production_with_sludge.pdf","download_url":"https://www.academia.edu/attachments/36367294/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&","bulk_download_file_name":"Improved_sustainability_of_feedstock_pro.pdf","bulk_download_url":"https://d1wqtxts1xzle7.cloudfront.net/36367294/2_Improved_sustainability_of_feedstock_production_with_sludge-libre.pdf?1421970645=\u0026response-content-disposition=attachment%3B+filename%3DImproved_sustainability_of_feedstock_pro.pdf\u0026Expires=1732726388\u0026Signature=QTcystP1HAarjbHfj5eK9mG~RRJledt2pSIloD6~YTGWzwTvXaRQnn-l9WuL6BePtX3B8xVtPDDj3Fg-vCGWM5g6zXp5tZguAa6-EI2i9pLD~avM-eHsfDQ4gushaXK65b-~B-wXq~pOq~q7U88UosNB9Y3lRLN2~VK1TT-Nz8Bn2-GHhX59Svg18GPO2gbYeKRj4otHXqpdFmDc-ioejGcgOn1zWvCosp1o0PKZD5xWajdTwZT-tDjrgw7~lSZhqnM3LCh~Sj~pwm3WplrZlmMjiKMGmlTeTeFMM1clESTH5-Btyb3k~aj97DxDYY5EpJaW2xZ~AY9hXDeCXl~TQg__\u0026Key-Pair-Id=APKAJLOHF5GGSLRBV4ZA"}],"research_interests":[{"id":57697,"name":"Heavy metals","url":"https://www.academia.edu/Documents/in/Heavy_metals"},{"id":67661,"name":"Sewage sludge","url":"https://www.academia.edu/Documents/in/Sewage_sludge"},{"id":592629,"name":"Mycorrhizae","url":"https://www.academia.edu/Documents/in/Mycorrhizae"},{"id":820159,"name":"Bioenergy Crops","url":"https://www.academia.edu/Documents/in/Bioenergy_Crops"}],"urls":[{"id":1518619,"url":"http://www.sciencedirect.com/science/article/pii/S0045653513002725"}]}, dispatcherData: dispatcherData });

Therefore, a three-year field experiment was conducted to investigate the suitability of sewage and digested sludge in comparison to synthetic fertilizer on biomass production and its quality in three crop species, with specific attention to the relationship between N availability and biomass accumulation. Fertilizer treatments for each crop species were standardized on the basis of total Nitrogen as follows: maize 120 kg ha−1, fibre hemp 60 kg ha−1 and oilseed rape 90 kg ha−1 Nitrogen. The highest biomass yield of maize (30 Mg ha−1 Dry Mass) and hemp (15 Mg ha−1 Dry Mass) was obtained from the sewage sludge treatment. The sludge treatment also gave the highest leaf Nitrogen mass in biomass of both maize (14 g kg−1) and hemp (18 g kg−1) at 60 DAS (flowering stage). Sewage sludge increased slightly gross energy yield of maize (438 GJ ha−1) and hemp (272 GJ ha−1) in comparison to other treatments. The mass fraction of ash and the combustion-relevant elements such as Chlorine, Potassium, Sodium and Calcium were lower in crops fertilized with sewage sludge than in those fertilized with synthetic fertilizer.

However, sowing date on 15th December caused an increase in most of technological properties (protein and wet and dry gluten percentages), milling characteristics (fine and coarse bran percentages) and rheological properties (water absorption percentage, dough stability time and resistance to extension).</span></div><div class="wp-workCard_item wp-workCard--actions"><span class="work-strip-bookmark-button-container"></span><a id="c6a85ef6230a52b7053366c8ee1735dc" class="wp-workCard--action" rel="nofollow" data-click-track="profile-work-strip-download" data-download="{"attachment_id":30286126,"asset_id":2232975,"asset_type":"Work","button_location":"profile"}" href="https://www.academia.edu/attachments/30286126/download_file?st=MTczMjc5MjEzNiw4LjIyMi4yMDguMTQ2&s=profile"><span><i class="fa fa-arrow-down"></i></span><span>Download</span></a><span class="wp-workCard--action visible-if-viewed-by-owner inline-block" style="display: none;"><span class="js-profile-work-strip-edit-button-wrapper profile-work-strip-edit-button-wrapper" data-work-id="2232975"><a class="js-profile-work-strip-edit-button" tabindex="0"><span><i class="fa fa-pencil"></i></span><span>Edit</span></a></span></span><span id="work-strip-rankings-button-container"></span></div><div class="wp-workCard_item wp-workCard--stats"><span><span><span class="js-view-count view-count u-mr2x" data-work-id="2232975"><i class="fa fa-spinner fa-spin"></i></span><script>$(function () { var workId = 2232975; window.Academia.workViewCountsFetcher.queue(workId, function (count) { var description = window.$h.commaizeInt(count) + " " + window.$h.pluralize(count, 'View'); $(".js-view-count[data-work-id=2232975]").text(description); $(".js-view-count[data-work-id=2232975]").attr('title', description).tooltip(); }); });</script></span></span><span><span class="percentile-widget hidden"><span class="u-mr2x work-percentile"></span></span><script>$(function () { var workId = 2232975; window.Academia.workPercentilesFetcher.queue(workId, function (percentileText) { var container = $(".js-work-strip[data-work-id='2232975']"); container.find('.work-percentile').text(percentileText.charAt(0).toUpperCase() + percentileText.slice(1)); container.find('.percentile-widget').show(); container.find('.percentile-widget').removeClass('hidden'); }); });</script></span><span><script>$(function() { new Works.PaperRankView({ workId: 2232975, container: "", }); });</script></span></div><div id="work-strip-premium-row-container"></div></div></div><script> require.config({ waitSeconds: 90 })(["https://a.academia-assets.com/assets/wow_profile-f77ea15d77ce96025a6048a514272ad8becbad23c641fc2b3bd6e24ca6ff1932.js","https://a.academia-assets.com/assets/work_edit-ad038b8c047c1a8d4fa01b402d530ff93c45fee2137a149a4a5398bc8ad67560.js"], function() { // from javascript_helper.rb var dispatcherData = {} if (true){ window.WowProfile.dispatcher = window.WowProfile.dispatcher || _.clone(Backbone.Events); dispatcherData = { dispatcher: window.WowProfile.dispatcher, downloadLinkId: "c6a85ef6230a52b7053366c8ee1735dc" } } $('.js-work-strip[data-work-id=2232975]').each(function() { if (!$(this).data('initialized')) { new WowProfile.WorkStripView({ el: this, workJSON: {"id":2232975,"title":"Effect of Sowing Dates on Productivity, Technological and Rheological Characteristics of Bread Wheat","translated_title":"","metadata":{"abstract":"The aim of this investigation was to determine the effect of different sowing dates (i.e., 1st November, 15th November, 1st December and 15th December) on growth, grain filling traits and yield and it components as well as grain quality and rheological properties of bread wheat (Triticum aestivum L.) cultivar Gemmeiza 9 during two growing seasons in Nile Delta region, Egypt.
