Abstract:
A field experiment entitled “Studies on nitrogen source diversification in vertisols and its effect on soybean productivity” was conducted during the year 2017-18 at the Research Farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment was laid out in randomized block design with three replications. The treatments were comprised of seven nutrient management practices viz., RDF (30:75:30 NPK kg ha-1) and in remaining six treatments, 50% RDN was given through urea and 50% RDN through different organic sources viz. Vermicompost, FYM + Jivamrut, FYM, Compost, soybean crop residue + Trichoderma viride and Gliricidia leaf incorporation. It was found that highest values of growth parameters and yield parameters was noticed with treatment RDF alone (35.88 g) being at par with treatment 50%RDN + 50% N through vermicompost.
