Abstract:
A field experiment was conducted during Rabi, 2019-20 entitled, “Effect of Integrated Nutrient Management on growth and yield of Lablab bean (Lablab purpureus) and soil properties in Alfisols” at Dapoli. The experiment was laid out in Randomized Block Design (RBD) comprising sixteen treatment combinations and replicated thrice. The effect of different inorganic fertilizers alone (Urea and SSP) or in combination with organic manures (Farm yard manure, vermicompost and poultry manure) and Biofertilizers (Rhizobium and PSB) on chemical properties of the soil, growth, yield, quality and nutrient content of lablab bean (var. Dapoli-2) were studied. The chemical properties viz., Soil reaction, Electrical conductivity and Organic carbon content of soil did not show a significant change in their status. However, available macronutrients (N, P, K,) and micronutrient (Fe, Mn, Zn, Cu) status showed significant improvement as a consequence of various treatment combinations. In general, chemical properties of experimental plot represented a typical lateritic soil of Konkan (M.S.). The application of equal integration of RDN through inorganics and through organics, either through poultry manure or vermicompost with or without bio-inoculations proved its significance and enhanced macro (N, P, K) as well as micro nutrients (Fe, Mn, Zn and Cu) status of soil.
