This paper examines the changes in the agriculture of green revolution states. The results revealed that a decrease in the share of agriculture in state domestic product was not accompanied by appropriate fall in the workers in agriculture. Consequently, man-land ratio increased over time, markedly in West U.P. The share of purchased and energy based inputs has increased over the years and formed about 50 per cent of the operational cost. The share of capital in gross value added was substantially higher than that of human labour in the production of wheat, whereas the share of capital and human labour was almost equal in the case of paddy. A sharp decline in the returns to management in the production of wheat calls for developing cost saving technology and reappraisal of price policy.
