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