Impact of Organic and Inorganic Fertilizers on Yield and Yield Contributing Characters of Mustard (Brassica napus L.)

Bangladesh is a densely populated country where the oil crisis one of major issues. On other hand, balanced fertilizer used lacking until now. The purpose study to investigate yield Mustard (Brassica napus L.) Binasarisha-9 influenced by different applications organic fertilizers. experiment was conducted at Institute Nuclear Agriculture (BINA), substation, Satkhira during rabi season 2020-2021 observe effect and inorganic fertilizers on mustard viz determine best dose combined application for optimum Binasarisha-9. laid out in randomized complete block design (RCBD) comprising five treatments (T1= Absolute control, T2=recommended chemical (RDCF), T3=50% RDCF+ 5t/ha vermicompost, T4= 50% poultry manure, T5= 5 ton/ha cow dung) with three replications were executed conduct study. responded significantly T3 treatment (50% vermicompost). highest recorded (2.14 tons/ha) from whereas lowest (0.81 ton/ha) obtained T1= (absolute control) treatment. Balanced nutrient management increased compared imbalanced Organic (vermicompost, cow-dung) showed better uptake However, vermicompost tends be most suitable source higher thus proper substitute commonly sources production mustard.
