Abstract

Effects of conservation agriculture (CA) on crop yield may be positive or negative (Pittelkow et al., 2015) depending upon the crop species, growing e nvironment, and the duration and extent of the CA system. CA involves use of minimum tillage, stubble retention and Minimum tillage can slow down the residue decomposition and reduce the release of mineral forms of nitrogen (N) (Hobbs et al., 2008). Hence, N in the system might be less available under minimum tillage, at least in the initial years. However, no data are yet available to assess the requirement of N fertilizer under CA in the rice-based cropping systems. Lundy et al. (2015) found in the tropical and subtropical regions that decreased yield with the implementation of minimum tillage was sensitive to the rate of N fertilization. Thus, the present study was undertaken to determine the effect of strip tillage with increased residue retention on system productivity, soil organic matter and N requirement in a rice-wheat-mungbean cropping system.
