Assessing rice residue and nitrogen management strategies on productivity and nitrogen use efficiency of wheat in rice-wheat cropping system in Indo-Gangetic Plains

Abstract

Rice-wheat cropping system produces ample scattered rice residue in the field after mechanical harvesting which holds no economic value for the farmers in the Indo-Gangetic Plains (IGP) of South Asia. Several options are available for managing rice residue, enabling wheat seeding in the succeeding season to avoid its burning. However, limited information is available on the efficient nitrogen management practices under different rice residue management options to achieve higher wheat productivity and N use efficiency (NUE).
