Nitrogen Mineralization, Forms of Acidity and Fertility Status of a Paddy Soil as Influenced by Rice Stubble Management

Abstract

The productivity of winter rice in Assam has remained static during last decade (Anonymous, 2019) contrast to increase in high yielding variety acreage and total fertilizer consumption. Application of mineral fertilizer without organic manure or recycling of crop residues strongly affects soil productivity (Singh et al., 2001). The stubble management, which is left in the field till the next crop, in rice sole crop areas of the state deserves relook mainly for two reasons. First, simple and feasible rice stubble management
