Influence of Integrated Nutrient Management with Foliar Application of Mono Potassium Phosphate on Soil Health in Cultivation of Cowpea (Vigna unguiculata L.) Var. Mohini 34

Abstract

The study was conducted during the Kharif season of 2023-24 at the Soil Science Crop Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was arranged in a Randomized Block Design with three replications. The investigation focused on the impact of various treatments on soil health. The findings revealed several significant outcomes: Regarding soil health parameters, the application of integrated nutrient management (INM) and foliar application of Mono Potassium Phosphate (MKP) influenced bulk density, particle density, pore space, water retaining capacity, pH, electrical conductivity (EC), organic carbon content, as well as nitrogen, phosphorus, and potassium levels in the soil. Notably, certain treatments led to a decrease in bulk density and EC, while enhancing organic carbon content and nutrient availability in the soil. In conclusion, the study underscores the importance of integrated nutrient management practices, including foliar application of MKP, in enhancing soil health parameters. These findings provide valuable insights for sustainable agricultural practices aimed at optimizing crop productivity while preserving soil health.
