In the present study data for consumption of farm inputs and production value of various crops for 11 successive years were analysed to study the contribution of farm inputs on crop production. The compound annual growth rate for total value of production was 3 per cent and those for seed and fertilizer consumption were 4.2 and 1.59 per cent respectively. The compound annual growth rate of pesticide, farm implement, farm machinery and plant protection equipment were negative. Strong

Principal component analysis identified two, components contributing 97.8 per cent variation. Functional form of production with the extracted two principal components showed that though fertilizer and pesticide had significant contribution towards crop production at 0. 0 I level of significance other inputs have also substantial effect on crop output.
