EFFECT OF DIFFERENT MICRONUTRIENTS ON CANE YIELD AND JUICE QUALITY OF SUGARCANE

摘要

An experiment was conducted during the years 1999 to 2001 on effect of micronutrients application on cane yield and juice quality of sugarcane plant crop with an early variety 91 V 83 in clay loam soil. In this study, application of recommended dose of 168 kg N - 75 Kg P_2O_5 -100 kg K_2O/ha along with foliar spray of 0.5% FeSO_4 twice at 45 and 90 days after planting sugarcane (T_3) recorded higher cane yield of 118.9 t/ha and juice sucrose of 19,93% which was on par with addition of recommended dose of NPK along with foliar spray of 0.2% ZnSO_4 twice at 45 and 90 days after planting (T_4 -118.2 t/ ha & 19.63%) and both were significantly higher over application of recommended dose of NPK alone (T_1 -111.4 t/ha) in cane yield while T_3 alone showed significantly higher juice sucrose over T1 (19.40%). While significantly lower cane yield of 69.3 t/ha and juice sucrose of 17.99% were obtained by absolute control (T_9) where no fertilizers were applied.
