Influence of nutrient management practices on microbial activity, fertility and yield of paddy

Abstract

A field study was conducted during kharif 2019-20 to understand the effect of different paddy growing practices on microbial activity, fertility and yield of paddy. The soil samples were collected from certified organic farmer’s lowland, conventional lowland and upland, INM lowland and upland fields in Kamthi and Mouda tehsil of Nagpur district to assess the soil properties like chemical, biological properties and yield under paddy cultivation on farmers field. The results showed that the highest N, P content recorded in organic lowland practice whereas, available K was higher in INM lowland. The DTPA extractable Fe, Zn, Cu and Mn status were highest observed in organic lowland and lowest occurred in conventional practices. SMBC and DHA highly occurred in organic lowland and INM upland practice and yield is also higher in INM lowland farmers field followed by organic lowland practice.
