Effect of different level of NPK, zinc and vermicompost on the soil health parameters and the yield of white maize (Zea mays L.) var. HM-12

Abstract

An experiment was conducted during in Kharif season (July 2023 - August 2023) to study the “Effect of different level of N, P, K, Zinc and Vermicompost on Soil Health Parameter and Yield of White Maize (Zea mays L.) Var. HM-12 in Prayagraj”. A randomized block design was used to set up the experiment, with three levels of NPK (0%, 50%, and 100% NPK), three levels of zinc (@ 0%, @ 50%, and @ 100% zinc) and three levels of Vermicompost (@ 0%, @ 50%, and @ 100% vermicompost). The results shows that inorganic fertilizer application had a non-significant effect on soil physical-chemical parameters (BD, PD, pH, EC and OC) and significant increase in pore space, water holding capacity, available nitrogen, phosphorus, potassium, zinc and vermicompost in treatment T9 - [NPK @ 100% + Zinc @ at 100% +Vermicompost @ 100%] that found to be best than any other treatments.
