Abstract:
Requirement of micronutrients i.e., ammonium molybdate, boric acid, copper sulphate, ferrous sulphate and zinc sulphate for amelioration of growth, yield and quality parameters of broccoli (Brassica oleracea var. italica) cv. Pusa KTS-1 was studied under field condition. Each micronutrient consisted of three different concentrations (C) 0.20%, 0.40% and 0.60% and applied as foliar feeding to broccoli crop along with control. First spraying of broccoli plants was done on 25th day of planting and subsequently 2nd and 3rd at 45th day and 65th days after transplanting. The result clearly indicated the positive influence of applying micronutrients on yielding maximum plant spread, stalk length, root length, curd yield, ascorbic acid %, reducing sugar %, TSS %, carbohydrate % and minimum days to 50% days to maturity with respect to control. The treatment (T15) zinc sulphate @ 0.60% exhibited highest value of plant spread, stalk length, root length and ascorbic acid content. Foliar application of (T7) copper sulphate @ 0.40% resulted in minimum number of days to 50% maturity (72.36). However, treatment (T5) boric acid @ 0.40% resulted in maximum pooled value of curd yield (135.05 q/ha), TSS% and carbohydrate %. Foliar application of (T2) ammonium molybdate @ 0.40% recorded the maximum pooled value of reducing sugar content (0.81%). Thus, foliar application can be promising approach to maximise broccoli growth and productivity.
