The average response to applied fertiliser N has been declining steadily over the past decades.

Considering the increasing demand of N fertiliser in the coming years, wide variability in soil N supplying capacity and wide production gaps in the predominant cereals, the present on-farm study was undertaken in the Indo-Gangetic Plains (IGP).
