EFFECT OF ORGANIC AND INORGANIC SOURCES OF NUTRIENT IN COMBINATION WITH SOIL AND FOLIAR APPLICATION OF ZINC IN RICE (Oryza sativa L.)

Abstract

The experiment consisted of ten treatments laid out in Randomised Block Design and replicated thrice with two factors viz Factor A: ZnSO₄ at 15kg/ha, 25kg/ha and 0.5% foliar application at 30 and 60 DAT and Factor B: Organic manure at FYM 6t/ha, Vermicompost 2t/ha and Poultry manure 1980 kg/h. The significant and maximum value in growth parameters like number of tiller/hill (11.46), Plant dry weight (60.68 g), as well as yield attributes character like Number of grain/panicle (252.00), Test weight (33.03 g), and Grain yield (7.94 t/ha) was recorded maximum in Treatment 5 (90 kg N/ha + 2000 kg /ha VC + 25 kg/ ha ZnSO₄ at Transplanting). the maximum B:C i.e.  2.72 was found treatment 5 i.e. 90 kg N/ha + 2000 kg /ha VC + 25 kg/ ha ZnSO₄ at Transplanting which is followed by Treatment 3 (2.62) i.e.90 kg N/ha + 6 t/ha FYM + 15 kg/ha ZnSO₄ at Transplanting).
