According to the results, the highest maturity index 21.46 with 1\/9 CTR application; the highest grape juice yields 736.67 ml with 1\/3 CTR + BA application; the highest L* color value 32.07 with 1\/9 CTR application; the highest a* color value 1.74 with 1\/9 CTR application; the highest b* color value 3.72 with 1\/9 CTR application were obtained. The effects of applications on grape fresh yield, cluster weight and berry weight were not found statistically significant.<\/p>\r\n","references":"[1]\thttp:\/\/faostat.fao.org.
