Abstract:
A field experiment was conducted during Rabi season of 2019-20 and 2020-21 at the Agricultural research farm of Rama University, Mandhana, Kanpur (U.P), to assess the response of integrated nutrient management on yield and economics of wheat. The soil of the experimental field was sandy loam with pH 7.5, 0.41% organic carbon, 0.13 dSm^-1 electrical conductivity, having available nitrogen 227.6 kg ha^-1, available phosphorous 13.9 kg ha^-1 and available potassium 173.9 kg ha^-1. The experiment comprised 11 treatments, viz., T₁-Control, T₂-100% NPK (120:60:40 kg ha^-1), T₃-100% NPK+ Zn (5 kg ha^-1), T₄-100% NPK + Zn + S (25 kg ha^-1), T₅-100% NPK + Zn + S + Azotobactor + PSB, T₆-100% NPK + Zn + S + Vermicompost (5.0 t ha^-1), T₇-100% NPK + Zn + S + FYM (5.0 t ha^-1), T₈-100% NPK + Zn + S + Vermicompost (5.0 t ha^-1) + Azotobactor + PSB, T₉-100% NPK + Zn + S + FYM (5.0 t ha^-1) + Azotobactor + PSB, T₁₀-75% NPK + Zn + S + Vermicompost (10.0 t ha^-1) + Azotobactor + PSB, T₁₁-75% NPK + Zn + S + FYM (10.0 t ha^-1) + Azotobactor + PSB. The experiment was laid out in randomized block design, replicated thrice. The maximum grain yield (4.72 and 4.95 t ha^-1) were recorded in application of 75% NPK + Zn + S + Vermicompost (10.0 t ha^-1) + Azotobactor + PSB (T₁₀) was statistically superior over all the treatments except T₁₁ and T₈ during both the year. Application of 75% NPK + Zn + S + Vermicompost (10.0 t ha^-1) + Azotobactor + PSB (T₁₀) recorded higher net return (Rs 57,690 ha^-1 and Rs 58,170 ha^-1) and maximum B:C ratio (1.61:1, 1.58:1) were recorded under 100% NPK + Zn + S + Azotobactor + PSB (T₅) during both the years.
