Response of Bio-organics on Soil Fertility Status, Growth and Yield Parameters of Black Gram (Vigna mungo) var. Shekar 2

An experiment to study the response of bio-organics on soil fertility status, growth and yield parameters Black Gram (Vigna mungo) was conducted during Zaid (April- July) season in 2021-22 at central research farm department Soil Science Agricultural Chemistry, SHUATS, Prayagraj. The Experiment a randomized block design with having two factors three levels both vermicompost b Neemcake 0,50, 100% per ha resulting nine treatments Data collected included bulk density, particle pore space, water holding capacity, pH, EC, organic carbon, nitrogen, phosphorus potassium. On gram plant height, number leaves plant, pod length, pods test weight, dry weight grain were collected. Treatment 9 which comprised neem cake 5 t ha-1 had an effect physical chemical properties soil. Results significant maximum values space 48.20% 46.96%, capacity 43.22 41.98%, carbon (%) (0.181and 0.182%) , Nitrogen 264.45 265.50 kg ha-1) Phosphorus 24.82 24.15 Potassium 186.58 178.41 0-15 15-30 cm depths respectively. same treatment recorded height 34.6; branches 37.33; 31.66; 32.88; 21.65; (B:C) ratio 1:1.56; gross returns Rs/ha-1 129600 net profit 74720 highest 12.096 75 DAS Further experimentation will help better understand effects make desirable recommendations.
