An experiment was conducted on cultivation of kharif maize with addition of different types of fertilizer and manure with different level. Vermicompost had increased the bulk and particle density, pore space, and water holding capacity, electrical conductivity and reduced pH and increased organic carbon content, available nitrogen, phosphorous and potassium activity in optimized treatment. Trial was conducted to obtain data the most acceptable level of Vermicompost (15 t ha-1) on the basis of physico-chemical properties of soil. Based on physico-chemical properties of soil the final optimized treatment was T6 contains Bulk density 1.65 Mg m-3, Particle density 2.65 Mgm-3, Pore spore44.56%, Water holding capacity 39.87% pH 6.72, EC 0.20dSm-1, Organic carbon 2.92 %, Available nitrogen 302.10 kg ha-1, Available phosphorus 27.53 kg ha-1 and Available Potassium 410.37 kg ha-1. Addition of vermicompost continuously increased the production of kharif maize.
