Abstract: The experiment was carried out at Banana Research Station, Nanded to study the effect of micronutrients with chemicals on growth, maturity and yield of banana. The experiment was laid out in Randomized Block Design with three replications and thirteen treatments of different concentrations and combinations of micronutrient viz. ZnSO4 (0.5%), B2 (SO4)3 (0.1%), KH2PO4 (0.5 %), FeSO4(0.2%), CuSO4(0.2%), chemical (0.5%) plant growth regulators (GA3 80 ppm) were sprayed at 5th, 6th and 7th months after planting and at flag leaf stage. The observations on growth, maturity and yield attributes were recorded during investigation. The maximum growth parameters and the highest yield parameters such as height of plant (170.21 cm), girth of stem (66.29 cm), number of leaves per plant (14.15), weight of bunch (21.77 kg) and average yield (94.12 Mt/ha) were recorded in treatment T6 i.e ZnSO4 (0.5%) + B2 (SO4)3 (0.1%) + KH2PO4 (0.5 %) which were 13.44, 24.43, 16.94, 75.28, and 70.50 per cent, respectively and more as compared to control. Maturity parameters such as days require from flowering to maturity (120.15 days) and crop duration (351.40 days) was found minimum in treatment T6 i.e ZnSO4 (0.5%) + B2 (SO4)3 (0.1%) + KH2PO4 (0.5 %) which were 14.30 and 1.88 per cent, respectively less as compared to control. It is concluded that foliar application of T6 i.e ZnSO4 (0.5%) + B2 (SO4)3 (0.1%) + KH2PO4 (0.5 %) at 5th, 6th an 7th months after planting and sparaying of chemicals at flag leaf stage found to be better for early maturity and better yield in banana.
