Influence of integrated nutrient management on growth dynamics and developmental stages of barley (Hordeum vulgare L.)

Abstract

The present investigation was conducted during 2024-25 at the Agronomy Research Farm, School of Agricultural Sciences, Jaipur National University, Jaipur, Rajasthan, with the objective of evaluating Integrated Nutrient Management (INM) practices in barley (Hordeum vulgare L.). The experiment was laid out in Randomized Block Design with three replications. The experiment consists of nine treatments as follows, T1: Control (no treatment applied); T2: 100% RDF (60 N + 30 P₂O₅ kg/ha); T3: Vermicompost at 5 t/ha; T4: Azotobacter (seed treatment) + Vermicompost @ 5 t/ha; T5: 50% RDF + Vermicompost @ 2.5 t/ha; T6: 75% RDF + Vermicompost @ 2.5 t/ha; T7: 50% RDF + Azotobacter (Seed treatment)) + Vermicompost @ 2.5 t/ha; T8: 75% RDF + Azotobacter (Seed treatment) + Vermicompost @ 2.5 t/ha; T9: 100% RDF + Azotobacter (Seed treatment) + Vermicompost @ 2.5 t/ha. The present study revealed that significantly higher plant height, number of tillers per metre row length and dry matter accumulation (g/m2) with the soil application of 100% RDF + Azotobacter (Seed treatment) + Vermicompost @ 2.5 t/ha (T9) and it was at par with 75% RDF + Azotobacter (Seed treatment) + Vermicompost @ 2.5 t/ha (T8) and 100% RDF-60 N + 30 P₂O₅ kg/ha (T2) compared to rest of the treatment. Whereas, Integrated Nutrient Management practices did not exhibit a significant influence on plant stand, days required to 50% flowering and maturity.
