The research work aimed to investigate the effect of various nutrient management modules on growth and yield of wheat crop. Was carried out during two consecutive rabi seasons of 2019-20 and 2020-21 The experiment was laid on randomized block design with 14 treatments, i.e., Control (T1)N, P₂O₅ and K₂O i.e., @ 150, 60 and 40 kg ha^-1, T₁: RDF (150:60:40 kg ha^-1 NPK), T₂: RDF + 20kg ZnSO₄ ha^-1, T₃: RDF + 5 t FYM ha^-1, T₄: RDF + 2.5 t VC ha^-1, T₅: RDF + 5 t FYM + 20 kg ZnSO₄ ha^-1, T₆: RDF +2.5 t VC + 20 kg ZnSO₄ ha^-1, T₇: 75% RDF(112.50:50:45 kg ha^-1), T₈: 75% RDF + 20 kg ZnSO₄ ha^-1, T₉: 75% RDF + 10 t FYM ha^-1, T₁₀: 75% RDF + 5 t VC ha^-1, T₁₁: 75% RDF +10 t FYM + 20 kg ZnSO₄ ha^-1, T₁₂: 75% RDF + 5 t VC + 20 kg ZnSO₄ ha^-1, T₁₃: 125% RDF (187.50:75:50 kg ha^-1), T₁₄: 125% RDF + 20 kg ZnSO₄ ha^-1. The treatments consisting different combinations of organic (vermicompost and FYM) and inorganic (RDF and ZnSO₄) fertilizers were being tested in Randomized Block Design with three replications to examine the impact of nutrient management modules having chemical fertilizers alone and their combination with organic sources on productivity, nutrient uptake and soil properties taking wheat as test crop. The maximum N, P, K, S and Zn uptake were noticed under the treatment T₆ (100% RDF + 2.5 t VC + 20 kg ZnSO₄ ha^-1) followed by treatment T₅ (100% RDF + 5 t FYM +20 kg ZnSO₄ ha^-1). Yield attributes and yield of wheat crop were recorded under the nutrient management module T₆ (100% RDF + 2.5 t VC + 20 kg ZnSO₄ ha^-1) closely followed by T₅ (100% RDF + 5 t FYM + 20 kg ZnSO₄ ha^-1). Significantly higher grain and straw yield were recorded under treatment having T₆ (100% RDF +2.5 t VC + 20 kg ZnSO₄ ha^-1) over T1 (100% RDF). The significant differences were found in case of protein content also. The highest value of pooled protein content was recorded in treatment T₆ (100% RDF + 2.5 t VC + 20 kg ZnSO₄ ha^-1). Most of the growth and yield related parameters of wheat crop was found significantly maximum in treatment T6. Nutrient analysis and its uptake in wheat under the effect of nutrient management module is also explored and presented in this research work.
