Abstract :

Background and Objective: Sugar beet, as one of the important sources of energy supply, plays an important role in food security of society. Therefore, the optimal use of agricultural inputs in the production of this product, in addition to increasing productivity and reducing production costs, leads to reducing greenhouse gas emissions and reducing the negative impact of improper consumption of agricultural inputs on the environment. Finds. In this regard, the purpose of this study was to determine the efficiency range of farmers based on the use of agricultural inputs in an optimistic-pessimistic framework, and analyze the environmental effects of input consumption. Material and Methodology: Information needed to conduct research was collected through interviews and completing 48 questionnaires among sample beet growers in Ghaen city in the 99-98 crop year. Findings: The average efficiency of farmers in the output-input mode was equal (0.7011, 1.7606) and the average efficiency of farmers (0.427, 0.0352) was calculated. The results show that 42.7% of the product is produced per unit consumption. Also, the average amount of inputs such as: seed consumption, phosphate fertilizer, nitrogen and toxins in the production of sugar beet, respectively, is estimated at 3.370, 54.2, 139.70 and 2.523 kg / ha. The amount of carbon dioxide emitted due to the production of sugar beet and the consumption of essential inputs such as: nitrogen fertilizer, and seed consumption, the toxin is 1480.73, 984.65, 1.53, 11.49 kg / ha, respectively. According to the results, nitrogen fertilizer has the greatest environmental impact. Discussion and conclusion: In the production of sugar beet, different types of inputs are used, which in addition to increasing the yield, also have an environmental effect. Therefore, by informing farmers through their presence and participation in extension classes and also by educating farmers about the proper management and consumption of chemical inputs, the harmful effects of their overuse in the production process can be prevented. Brought. In order to reduce the biological and protective effects, reduce the use of chemical fertilizers and replace livestock and organic fertilizers by producers and policy makers should be considered. Also, review the implementation of subsidy reduction policies and the realization of the price of chemical fertilizers and consumer inputs.
