Increasing the production potential and quality of soybean through integrated nutrient management practices in vertisols

Abstract

A field experiment was conducted in 2016-17 and 2017-18 at the Research Farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra) to evaluate the yield response of soybean to various integrated nutrient management treatments. The treatments consisted of integrated nutrient management viz., S1 - RDF (30:75:30 NPK kg ha-1), S2 - 50% RDN + 50% RDN through vermicompost, S3 - 50% RDN + 50% RDN through FYM, S4 - 50% RDN + 50% RDN through compost and S5 - 50% RDN + 50% RDN through soybean straw + Trichoderma viride @ 1 kg ha-1 to soybean and replicated four times in randomized block design. The study revealed that, soybean seed yield, straw yield, oil yield, protein yield, GMR, NMR and B:C ratio were significantly enhanced with application of RDF (30:75:30 NPK kg ha-1) through chemical fertilizers. However, the application of 50% RDN + 50% RDN through vermicompost also improved all parameters equally. So, it could be concluded that application of 50% RDN + 50% RDN through vermicompost have feasibility of replacing at least 50% nitrogen through field application of vermicompost.
