Effect of integrated nutrient management on yield and uptake of nutrients by mothbean (Vigna acontifolia) in northern dry zone of Karnataka

Field experiment was conducted during kharif season 2018 at Regional Agricultural Research Station, Dry Land Agriculture, College of Agriculture, Vijayapur to study the effect of integrated nutrient management on yield and uptake of nutrients by mothbean in shallow black soils. The results revealed that highest yield and nutrient uptake by mothbean was recorded by application of 100% RDF of green gram (12.5:25:0 N: P2O5: K2O kg ha-1) + vermicompost at 1.0 t ha-1. The conjunctive use of vermicompost with 100% RDF significantly improved the status of primary and secondary nutrient content over the inorganic fertilizer alone. The combined use of inorganic and organic sources of nutrients improves soil fertility and productivity.
