Data on area, production and yield of crops are provided by the Ministry of Agriculture. We are providing here district-level data taken from the Ministry. The files taken from the Ministry have been cleaned up only in respect of creating neatly defined columns of data corresponding to different variables.
Data on crop yields primarily come from crop-cutting surveys. See Section 4.3 of the report for a discussion of statistics on crop production.
Data on area under different crops come from plot-by-plot records maintained by village-level revenue official (patwari) in former temporary-settlement areas. In former permanent settlement areas (West Bengal, Orissa and Bihar), they are based on sample surveys since plot-by-plot records are not maintained. In north-eastern States, data on crop areas are based on ad-hoc estimates made by the village-level officials. See Section 4.2 of the Rangarajan Commission report for a discussion of statistics on crop areas.
