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 residues + Trichoderma viride and Glyricidia leaf incorporation. The protein and oil yield, significantly improved with application of RDF through chemical fertilizers. Significantly highest uptake of nitrogen (134.36 kgha^-1), phosphorus (22.10 kg ha^-1) and potassium (92.28 kg ha^-1) was recorded with treatment RDF alone, which was statistically at par with treatment of application of 50% RDN + 50% RDN through Vermicomposting (130.46, 21.23, 88.01 NPK kg ha^-1 respectively).
