Influence of Different Levels of N, P, K and Organic Manures on Soil Health, Growth and Yield of Green Gram (Vigna radiata L.) cv. Samrat

An experiment was conducted on Influence of different level of N P K and organic manures on soil health, growth and yield of green gram (Vigna radiata L.) cv. Samrat at the research farm of soil Science and Agricultural Chemistry, design laid out in randomized block design (RBD) with three replications. Green gram was taken for study with recommended doses of fertilizers (N, P2O5 and K2O @ 20, 40 and 20 kg ha-1) was applied with organic manure (FYM, and Vermicompost). A variety of green gram Samrat was taken for a research trial. Bulk density (mg m-3) and Particle density (mg m-3) was maximum in T1 (NPK @ 0% + FYM @ 0% + VC @ 0%). Pore space (%), Water holding capacity (%), pH (1:2) w/v, EC (dS m-1), Organic carbon (%), Nitrogen (kg -1), Phosphorus (kg -1) and Potassium (kg -1) was maximum in T9 (NPK @ 100% + FYM @ 100% + VC @ 100%). In treatment T9 the highest grain yield (15.58 q ha-1) was obtained with C:B ratio of 1:3.26.
