The experiment was laid out in a randomized complete plot design with three replications. Soil chemical properties, growth and fresh rhizome yield reduced with frequencyintensity of tillage imposed while application of OBAPM increased them. Among the tillage practices, the highest fresh rhizome yield (15.0t ha1) was produced by ZTM which was significantly different from other tillage practices. Among the tillage &amp;amp;ndash; OBAPM combinations, the most satisfactorily yield (20.1t ha1) was produced by ZTMOBAPM while the lowest yield (15.7t ha1) was in CTOBAPM. </abstract> <index>Open Science Index 79, 2013</index> </article>
