Economics of Nitrogen Fertiliser Application in Rice, Wheat and Maize Grown in the Indo-Gangetic Plains

Nitrogen (N) is a key factor for cereal production in India. N is predominantly supplied to the plants through fertiliser application. The average response to applied fertiliser N has been declining steadily over the past decades. As a result, farmers are compelled to apply higher doses of fertiliser N to maintain the yields of the preceding years. Considering the increasing demand of N fertilizer 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). The objective was to estimate response of cereals (rice, wheat and maize) to N application, the economics and profitability of N application with changing fertiliser price scenario.
