Assessment of Variation in Physico-Chemical Properties of soil of Maize as Influenced by Levels of NPK, and Vermicompost at Eastern Uttar Pradesh, India

A field experiment was carried out throughout Zaid season 2022 on the research farm of Department Soil Science and Agricultural Chemistry, SHUATS, Prayagraj, to examine variations in physicochemical properties soil yield maize, as affected by levels NPK vermicompost eastern part Uttar Pradesh. The at test site sandy loam texture is located 25024’30’’ North latitude, 81051’10” East longitude, about 98 meters above sea level. designed a block-based design that randomly randomized with nine different treatments T1@0%NPK ha-1 + @0%Vermicompost ha-1, T2@0%NPK @50% Vermicompost T3 @ 0% @100% T4 50% +@ T5 , T6 @50%NPK +@100%Vermicompost T7 100% T8 T9 100%NPK ha-1+ ha-1. which were replicated thrice. soil's physico-chemical characteristics before sowing following crop harvest assessed using standard procedures. Bulk density, Particle percent pore space water holding capacity Was determined (Muthuval et al) pH, Ec organic carbon Digital pH meter, EC meter Walkley Black method respectively. Available N, P, K Kjeldhal Method, Colorimetric Flame photometric experimental findings showed space, for water, Ec, available found be significant various quantities included Vermicompost. Post-harvest (Water capacity, Electrical conductivity, carbon, nitrogen, phosphorus potassium) maximum underT9(100%NPK ha-1) followed T8(100%NPK ha-1). It also observed particle density improved under T9(100%NPK when compared other control combinations. gradually decreased an increased dose vermicompost. So, integrating inorganic fertilizers has resulted sole use RDF.
