This study suggested that for obtaining the optimum yield of principal crops, the use crucial inputs like manures and N, P and K fertilizers could be increased and use of bullock labour and human labour could be decreased by use of mechanical means such as tractor, sprayers, dusters and harvester in order to reduce the cost of cultivation and increase efficiency of resources. The input costs were substantially increased by four to five times over output prices because of inflationary pressure on input costs. Therefore, the support price policy for food-grains should help the farmers in...
