Abstract:
A field experiment was carried out during the winter (Rabi) season of 2022-23, at the student’s Research farm, AKS University, Sherganj, Satna (M.P.) to ascertain the effect of integrated nutrient management on growth, yield and uptake of N, P, K and Zn in pea (Pisum sativum L.).The experiment consisted of ten treatments i.e. T₁-Control, T₂-100% RDF (N20: P60: K40), T₃-75% RDF + FYM, T₄- 75% RDF + Vermicompost, T₅-75% RDF + Azotobacter, T₆-75% RDF + Azotobacter + PSB, T₇- 75% RDF + Vermicompost + Azotobacter, T₈- 50% RDF + FYM + Vermicompost, T₉- 50% RDF + Vermicompost + Azotobacter + PSB and T₁₀- 50% RDF + Vermicompost + PSB. The experiment was laid out in randomized block design with three replications. Growth parameters like plant height were noted highest with treatment, T₂- 100% RDF (N20: P60: K40) followed by T₇- 75% RDF + Vermicompost + Azotobacter. Yield attributing characters such as pod length, no. of pods/plant, no. of seeds/pod, fresh pod weight, green pod yield and test weight were found maximum in T₂-100% RDF (N20: P60: K40) followed by T₇- 75% RDF + Vermicompost + Azotobacter. Nutrient uptake in seed and straw was noted highest in T₂-100% RDF (N20: P60: K40) followed by T₇- 75% RDF + Vermicompost + Azotobacter. Highest seed yield (5733 kg/ha) was obtained from application of 100% RDF (N20: P60: K40) which was followed by T₇- 75% RDF + Vermicompost + Azotobacter which was 5233 kg/ha. Growth, yield and uptake of N, P, K and Zn were increased with increasing levels of NPK. Finally concluded that higher nutrient uptake (N, P, K and Zn) was observed when 75% RDF + Vermicompost + Azotobacter was integrated with the inorganic fertilizer compared to the inorganic fertilizer applied alone. The combination of FYM and biofertilizer with inorganic fertilizers improved soil fertility compared to applying inorganic fertilizers alone.
