Today, in order to provide food security and respond to the increasing demand due to population growth, most countries, including Iran, have paid special attention to wheat production. The adoption of incentive policies by governments to increase the production of this product has led to the widespread use of various production inputs, including chemical fertilizers, which have the possibility of soil and water pollution. The increase of these pollutions has caused a change of attitude in the field of food production. One of the most important of these attitudes is the sustainable production of sufficient food along with attention to social, economic and environmental dimensions. Therefore, in order to achieve this goal, it is necessary to optimize and increase the environmental efficiency and cost in the consumption of chemical fertilizer inputs. For this purpose, this study has investigated the cost and environmental efficiency of wheat farmers in Gachsaran using Data Envelopment Analysis (DEA) method. The required data were obtained using simple random sampling method and completing the questionnaire from the farmers of Lishter Plain in Gachsaran in 2018. The results showed that the average cost efficiency under the assumption of constant return to scale and variable return to scale is 0.536 and 0.662, respectively, and the average environmental efficiency is 0.569 and 0.691, respectively. Therefore, the improvement in technical efficiency can significantly reduce production costs and environmental inefficiencies for farmers. Therefore, it is recommended that the government, in addition to training farmers in the optimal use of chemical inputs, by applying support policies, encourages wheat farmers towards organic cultivation and production so that while providing their income, a healthier product reaches the hands of consumers and improves their environmental performance.

Analysis of technical efficiency of broiler production farms is necessary for optimal and economical use of available resources. The aim of this study was to measure and compare the technical efficiency of broiler production farms in Birjand and Darmian counties. The sample size was determined using Cochran's formula and the required data collected by completing a questionnaire from 201 active meat poultry units in Birjand and Darmian counties by random sampling method. Comprehensive Data Analysis (DEA) method used to analyze the data. The results showed that the average technical efficiency of poultry farmers in Birjand and Darmian counties was 93 and 88%, respectively, assuming a fixed return to the scale, and 95 and 93%, respectively, assuming variable returns to the scale, which is a statistically significant difference(p<0/05). Also, the capacity to improve production and efficiency in poultry farms in Darmian county is more than Birjand county and is estimated to be 11.7 and 7%, respectively. The average scale efficiency and technical efficiency (in both fixed and variable returns) of poultry units in Birjand county is more than Darmian county, which on the one hand indicates better management of resource use in poultry units of Birjand and on the other hand shows the potential to increase production and efficiency of poultry units in darmian. Therefore, without changing the production technology and by promoting technical and managerial factors from the most efficient poultry units to low efficiency poultry units, the gap between broiler poultry units in Darmian and Birjand can be reduced.
