Effect of different levels of NPK and vermicompost on chemical properties of maize [Zea Mays (L.)] Cv. MM2255

Abstract

Field experiments was conducted during 2015-2016 on clay loam, sandy loam soil evaluate “to study the Effect of different levels of NPK and Vermicompost on physico- chemical properties of soil” comparison to inorganic fertilizers nitrogen, phosphorous, potassium. Vermicompost had increased the pore space, reduced particle and bulk density, increased water holding capacity, cation exchange capacity, reduced pH and electrical conductivity, increased organic carbon content, available nitrogen, phosphorous, potassium and microbial population and activity in all the soil types, particularly clay loam soil. On the contrary, the application of inorganic fertilizers has resulted in reduced porosity, compaction of soil, reduced organic carbon and reduced microbial activity. For as soil amendment and soil quality improvement. Observed that, the application of NPK with Vermicompost were excellent source to fertilization than fertilizers only in soil.
