Crop production under optimal resource use and weather scenario in deep tubewell irrigated area in bangladesh

Abstract

Abstract : This study was undertaken in Bogra district of Bangladesh to assess the impact of farm resource optimization and uncertain weather situations on optimal crop production, farm income and employment in deep tubewell areas. Survey data were used to develop linear programming representative farm models. Optimal plans showed a mis-allocation of existing resources and there is considerable scope for increasing farm production, income and employment by reallocation of existing resources. The mis-allocation of resources on large farms was greater than that of on small farms. Farm households ware also modeled to simulate the impact of alternative weather scenario on resource use, crop production and net farm income. This analysis provided insights into how different types of farms could make trade-off among the production of competing crops. The analysis suggested that, a good year (favourable weather) increased cropped area and input use on large and small farms, which increased both crop production and net farm income. On the other hand, a poor (unfavourable weather) sharply reduced land and inputs use on farms, which drastically decreased crop production and net farm income. Thus, the government should take the necessary arrangements to forecast agro-climatic conditions well ahead so that farmer can take internal management decision to reduce losses and extension workers may direct farmers to better allocate of resources
