Effect of integrated nutrient management on soil properties, growth, yield and quality parameters of Indian mustard (Brassica juncea (L.) Czern)

Abstract:

A field experiment was conducted during 2025-26 at the Student Instruction Farm, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur, to evaluate the effect of integrated nutrient management (INM) on soil fertility, growth, yield, and quality of Indian mustard (Brassica juncea (L.) Czern), cv. Varuna. The experiment was laid out in a Randomized Block Design with eight treatments and three replications. Soil organic carbon, available N, P, and K were significantly maximum under T₈ (100% RDF + 25% N through FYM + Azotobacter + PSB). T₈ recorded the highest seed yield (27.73 q ha^-1), representing a 143% increase over control. T₈ was statistically at par with T₆ (75% RDF + 25% N through FYM + Azotobacter + PSB) for most yield parameters. Maximum test weight (5.47 g) was recorded under T₄ (75% RDF + 25% N through vermicompost). Seed protein content was highest under T₈ (23.08%). Based on one-year experimental results, T₈ appeared most promising for sustainable mustard productivity; however, multi-season evaluation is required before wider recommendation.
