Abstract:
The experiment was conducted in the Rabi season of 2022-2023 to ascertain the effect of integrated nutrient management on yield and uptake of mustard. The experiment was employed in Randomized Block Design with three replications. There were a total of twelve treatments viz., control (T₁), 100% RDF (80:60:40 kg NPK/ha) (T₂), 100% RDF + biofertilizers (Azotobacter + PSB) @ 7.5 kg/ha (T₃), 100% RDF + FYM @ 2 t/ha + S @ 25 mg/kg (T₄), 100% RDF + FYM @ 2 t/ha + ZnSO₄ @ 10 kg/ha (T₅), 100% RDF + FYM @ 2 t/ha + S @ 25 mg/kg + ZnSO₄ @ 10 kg/ha + Azotobacter (Seed treatment) (T₆), 100% RDF + FYM @ 2 t/ha + S @ 25 mg/kg + Zn S04 @ 10 kg/ha + Azotobacter (Seed treatment) (T₇), 75% RDF (T₈), 75% RDF + biofertilizers (Azotobacter + PSB) @ 7.5 kg/ha (T₉), 75% RDF + FYM @ 2 t/ha + S @ 25 mg/kg (T₁₀), 75% RDF + VC @ 2 t/ha + S @ 25 mg/kg + ZnSO₄ @ 10 kg/ha (T₁₁) and 75% RDF + FYM @ 2 t/ha + S @ 25 mg/kg + Zn S04 @ 10 kg/ha (T₁₂). The results revealed that integrated nutrient management enhanced the yield attributes, yield and uptake of N, P, K, S, and Zn. Application of T₆ (100% RDF + FYM @ 2 t/ha + S @ 25 mg/kg + ZnSO₄ @ 10 kg/ha + Seed treatment with Azotobacter) resulted in a higher number of siliquae per plant, number of seeds per siliqua, 1000 seed weight and seed yield of mustard. Furthermore, treatment T₆ also led to higher uptake of N, P, K, S and Zn by seed and straw of mustard.
