Abstract
Seeing the sustainability of rice-wheat cropping system (RWCS) of the Indo-Gangetic Plain, adequate crop
nutrition in general and nitrogen (N) in particular holds the key to sound crop management. The excessive
application or insufficient management of N means an economic loss to the farmer and may lead to yield penalties
and environmental problems. Improving N management in consonance with other nutrients is much important to
break yield plateaus as breeding for high yielding is not happening in recent years. Findings from farm survey
are used to evaluate the on-farm N management practices in rice crop of the study area. The crop management
practices (especially time of sowing/transplanting and irrigation requirement) and resource base of the farmers
decided the N use pattern of the farmers. The N Physical optimum and N economic optimum exceeding the recommended
levels revealed the apparent need for the revalidation of the existing recommendations. Paddy yield increased
significantly within different rice types. This study generated comprehensive data on N use pattern in rice in the
study area.
