IMPACT OF VERMICOMPOST AND ZINC IMPLEMENTATION ON SOIL PHYSICO-CHEMICAL PROPERTIES AFTER HARVEST OF MUNG BEAN

Abstract

At Research Farm, Department of Soil Science and Agricultural Chemistry, SHUATS, Prayagraj a field experiment was undertaken in the kharif season 2021-2022, with 9 treatments and 3 replications, the experiment was set up in a Randomized Block Design (RBD) includes Particle density ranged from 2.09 Mg m-3 to 2.26 Mg m-3 in 0-15 cm soil depth and 2.30 Mg m-3 to 2.37 Mg m-3 in 15-30 cm soil depth, bulk density ranging from 1.193 Mg m-3 to 1.290 Mg m-3 at 0-15 cm soil depth and 1.247 Mg m-3 to 1.365 Mg m-3 in 15-30 cm soil depth, Porosity ranged from 44.71 percent to 46.18 percent in the 0-15 cm of soil, but as depth increased, porosity declined, with the depth at 15-30 cm Porosity ranged from 40.39 percent to 43.93 percent. At 0-15 cm and 15-30 cm soil depths as due to the implementation of vermicompost and zinc a considerable impact on soil pH, EC, and Organic Carbon. At 0-15 cm soil level, available nitrogen content ranged from 177.00 kg ha-1 to 227.17 kg ha-1, while at 15-30 cm soil depth, available nitrogen content ranged from 184.60 kg ha-1 to 192.12 kg ha-1. In the 0-15 cm and 15-30 cm soil depths founded maximum available Phosphorus and available Potassium. The available zinc concentration in soil varies from 0.360 ppm to 0.570 ppm at 0-15 cm depth and 0.290 ppm to 0.530 ppm at 15-30 cm depth.
