Effect of organic and inorganic sources of nutrients on growth and yield attributing characters of mustard crop (Brassica juncea L.)

A field experiment was conducted to study the effect of organic and inorganic sources of nutrients on yield, quality and nutrients uptake by mustard (Brassica juncea L.) variety Pusa Mustard 30 (LES-43) at Crop Research Centre and Sardar Vallabhbhai Patel University of Agriculture Technology, Meerut during rabi season, 2016-17. The experimental results revealed that maximum growth parameters (plant height, branches plant-1, dry matter accumulation and leaf area index), yield attributes (siliqua length, siliqua plant-1, seeds siliqua-1 and test weight), yield (grain and stover), nutrient uptake (N,P, K and S) by grain and stover and available soil nutrient (N, P, K and S),were recorded with application of 50% RDF+ FYM 6 t/ha + Vermicompost 2 t/ha+ bio-fertilizer higher than the rest of the treatments. The increment in seed yield with application of 50% RDF+ FYM 6 t/ha + Vermicompost 2 t ha-1 + Bio-fertilizers was 168.35% over control. Maximum gross return, net return were recorded with the application of 50% RDF+ FYM 6 t ha-1 + Vermicompost 2 ha-1 + Bio-fertilizers, however B: C ratio was lower than the use of RDF only but in application of FYM and vermicompost improved the physio chemical properties of soil which may improved the sustainability of production system.
