Effect of NPK Levels and Bio-Organics on Growth, Yield and Economics of Basmati Rice (Oryza sativa L.) cv HUBR 10-9

摘要

A field experiment was conducted during kharif season of 2014 to evaluate the effect of different NPK levels and bio-organics on growth, yield and economics of basmati rice cv HUBR 10-9. Factorial experiment was laid out in randomized complete block design involving four NPK levels i.e. control, 50% RDF, 75% RDF and 100% RDF and three levels of bio-organics viz. FYM, FYM + BGA and FYM + BGA + PSB with twelve treatment combinations replicated thrice. Increasing NPK levels up to 100% RDF improved growth parameters, yield attributes, grain and straw yield. Combined application of FYM + BGA + PSB proved significantly superior over FYM + BGA and FYM alone. Economic analysis indicated that integration of 100% RDF in combination with FYM + BGA + PSB gave highest gross and net return. How-ever, maximum B:C ratio was registered with application of 75% RDF in combination with FYM + BGA + PSB.
