Effects of Integrated Nutrient Management on Soil Properties, Growth and Yield of Black Gram (Vigna mungo L.) var. Shekhar-2

Abstract

A field experiment was conducted at research farm of Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj, (U.P.) on sandy loam soil to Assess the “Effects of Integrated Nutrient Management on Soil Properties, Growth and Yield of Black gram (Vigna mungo L.) var. Shekhar-2” during Zaid season of 2022. The experiment consists of nine treatment combinations, comprised in randomized block design with three replications. To achieve higher growth and yield it was found application of T9 (RDF + 100% Rhizobium + 100% Biochar) has shown effective growth under Prayagraj climatic conditions. It was observed that for physical and chemical properties of soil in treatment T9 (RDF + 100% Rhizobium + 100% Biochar) were improved significantly due to the application of Nitrogen, Phosphorus, Potassium, Rhizobium and Biochar inputs. Bulk density (Mg m-3), Particle density (Mg m-3), Pore space (%), Water holding capacity (%), pH, Electrical conductivity (dS m-1), Organic carbon (%), Available Nitrogen (kg ha-1), Available Phosphorus (kg ha-1), Available Potassium (kg ha-1). The soil organic carbon content, Water holding capacity and available NPK significantly increased in most of the treatments after harvest of Black gram, it was observed that treatment T9 (RDF + 100% Rhizobium + 100% Biochar) was best in terms of growth, yield and economic parameters with maximum plant height, the number of branches plant-1, seeds pod-1, pod yield and maximum cost benefit ratio.
