Response of inorganic and organic sources of nutrients on growth, yield and quality of Mustard (Brassica juncea L.)

A field experiment was conducted during the Rabi season of 2022-2023 at Sardar Patel University, Balaghat (M.P.), to evaluate the effects of inorganic and organic nutrient sources on the growth, yield, and quality of mustard (Brassica juncea L.). The study aimed to assess individual and interactive effects of nutrient sources, and their economic viability. Results indicated that the application of 100:80:60 kg NPK/ha, particularly in combination with 5 t/ha of vermicompost, significantly enhanced growth parameters, yield attributes, and overall yield of mustard. This combination led to the highest seed yield (17.92 q/ha), oil content (386.7%), gross monetary returns (₹100841.56/ha), net monetary returns (₹68439.48/ha), and a favourable B:C ratio (2.11). The findings suggest that integrating inorganic fertilizers with organic sources like vermicompost can optimize mustard production and economic returns, though further validation from multi-year trials is recommended.
