The second group, who responded to the questionnaire population of binary comparisons and importance of questionnaire, is the experts Yazd Agricultural Insurance Fund. In the end the results showed that option, observance of justice by the insurance fund, the priority is superior to other options.

In this study, 2013-14 cross sectional data were collected through questionnaires from 201 irrigated wheat producers in Fasa applying multistage random cluster sampling to investigate the relationship between inputs and determine the returns to scale. The results translog cost function indicated that own-price elasticities of demand are negative for all inputs.Also based on the absolute values of the own-price elasticities and cross elasticities demand coefficients revealed by implementing the policy on input prices the producers do not have the ability to reaction against these policies Therefore, it is suggested to accomplish implementing the policies with more cautious and exact planning. Finally, with increasing returns to scale characteristics of wheat production in Fars province, in the present circumstances it is possible the average cost of production is reduced by increasing the scale of production and farmers to improve profitability will contribute to more economical the production process. Therefore, in such circumstances, it seems necessary government support for producers.

Due to the importance of agricultural processing industries as one the engine of agricultural development in particular, economic and industrial development in general, it is important to identify sources of agricultural processing industries growth from policy planning view. Foreign Direct Investment (FDI) is one of the things that, must study its impact on agricultural processing industries properly. To address this problem, the holistic approach (system thinking) used to study the impact of existence of infrastructure on investment growth, in this article. System Dynamics (SD) method used in this article as a tool for the implementation of system thinking approach to use its capabilities in complex systems modeling and for achieving suitable results from simulation model. The population under study is Fars province's agricultural processing industries. Period of study is 1360-1410. Vensim software used for modeling and simulating in this article. The results from the simulation of designed model showed, there is direct and interactive relationship between FDI and amount of investment in the agricultural processing industries. Although the delay affects this relationship.

In this study in order to compiling the management strategies of the Iranian Fisheries Organization, a series of interviews were conducted with a team of experts. Then, for determining the criteria and sub-criteria of the strategy evaluation, nine sub-criteria were selected in the form of three economic, environmental and management criteria. To evaluate these strategies, a questionnaire was developed to determine the weight of the criteria and sub-criteria and to determine the rating of each of the strategies. The results showed that the most effective criterion in the evaluation of strategies is the management criteria with a relative weight of 0.410. Economic and environmental criteria with weights of 0.300 and 0.290 are in the next category. The results also showed that the international marketing strategy for reaching the regional and global markets and Investments for using untapped and undeveloped aquatic resources respectively with the score of 0.761 and 0.324 have the highest and lowest rank among the strategies.

Increasing energy consumption in agriculture sector, causes emission of greenhouse gases that destroy environment and incur many costs on the society which is called destruction cost. Increasing the price of energy carriers, is one way to decrease the emission of air pollutants and destruction cost of them. Since this policy also has a economic effects, So the aim of this paper is to investigate this effects on the agriculture sector of Iran using a CGE model. Database for the CGE model, is social accounting matrix of the year (2004) for Iran. Results show that after shock, consumption of energy carriers, production level, domestic demand, employment and export falls and price of agriculture activities and import of them raises. On the other hand, emissions of air pollutants decreases and therefor destruction cost of Other Agriculture activity and Cultivation and Horticulture activity decreases about 251.9 and 748.5 billion rials (fix price of the year 2000). In total, destruction cost of agriculture sector falls from about 5% to almost 3.2% of the value added of agriculture sector.

The current study attemptted to investigate energy efficiency and analyze the relationship of potato production in of Hamadan provinces. The data were collected by using a proportional stratified random sampling method through interview and questionnaire. The sample size is about 139 farms. The total energy used and energy returns was calculated to analyze energy efficiencies such as energy ratio, energy efficiency and net energy use.the Data Envelopment Analysis(DEA) was applied to calculate technical, pure technical and scale technical efficiencies through BCC and CCR models. The results showed that, the total energy input for potato production in Hamedan and as follows: 66295.13 MJ. The first rank of energy used sources respect to inputs goes to fertilizers with 38.78 in Hamedan plain. The energy ratio, energy efficiency and net energy of potato farmer in Bahar were 2. 224, 0. 671 kg/MJ and 84751.885 MJ/ha respectively. The average of technical, pure technical and scale technical efficiencies was estimated as follows 0.748, 0.941, 0.80 respectively. In Hamedan Province the highest misuse consumption belongs to chemical fertilizer and seed.

The aim of this study was to determine the effect of prices of agricultural land in the city of Saveh Nobaran District Diem, the method is Hedonic.in order To estimate the equation, the data from the city of Saveh Agriculture and Water and Soil Lab barking Darwin city of Saveh, Agricultural Jihad Organization of the city Nobararan in crops 2014-15 extracted Diem. The number of agricultural land in the city of Saveh 614 pieces an area of approximately 20000 hectares is Nobaran. In the estimation model based on Cochran formula, 302 have been used. The effect of variables Land area, distance to the center of the village, away from the city center, distance from the nearest paved road, slope, soil texture and soil carbon content, the value of the land intended. According to results of the model, variables silty-sandy texture and increase soil carbon content, the positive impact of prices of agricultural land. Land Agricultural land slope and distance to the village, the negative impact of prices of agricultural land.

In this study, using annual data over the period 1992-2014, asymmetry of sugar market with Johansen co-integration technique and estimation of error correction model were investigated. The application of collective method in import market indicates at least one long-term relationship between the variables of domestic and import prices. Granger causality test showed that there was a one-way Granger causality relationship of import prices to domestic ones not a two-way causality relationship. The estimation of price transmission from imported to domestic price indicates asymmetry in price transmission mechanism of the market of sugar imports in Iran. The study of the main reason for this asymmetry is to use the concentration ratio indexes and Herfindahl- Hirschman indicating high concentration and the dominance of two countries of UAE and Brazil in the market of imports of sugar in Iran.

Poultry Meat is known as a basic commodity widely used by Iranian people. Investigating previous researches regarding analysis of poultry-meat prices, it is obtained that the presented models only predict and determine the prices based on independent variables and they had ignored the existing feedbacks affecting the price fluctuations. Previous researches are only able to predict the general trend with annual time units, while the most important factors that cause the fluctuations are the basic feedbacks especially supply and demand feedbacks. Furthermore, short term fluctuations such as monthly intervals are very important which are ignored. In this paper, by applying system dynamic methodology, the structure of poultry market and fluctuations mechanism in the prices are identified. In the presented model, the interaction between feedbacks of demand, domestic supply, import and production costs are considered. The results indicate that the main fluctuation is related to the approach to Nowruz holidays, which is Caused a significant price increase. According to the findings of the study, the increase in imports does not have much effect on pricing.

In the last decade the use of chemical fertilizers have been followed environmental consequences adverse such as water and soil pollution and health problems for humans and other living things. As the use of chemical fertilizers could create serious risks for the environment and public health, the aim of this study is to determine the optimal combination of fertilizers for crops in the Goharbaran region of Sari using Goal Programming model and the Game Theory, and finally, cropping pattern in the current and optimal fertilizer consumption for crops is discussed using Positive Mathematical Programming. Required data for this study has collected with interview of 250 farmers during the years 2014-2015. The results of this study showed that the consumption of fertilizers for all crops have not been optimal by representative farmers. Therefore, current fertilizer consumption for all crops is more than optimal value. Based on results of positive mathematical programming, despite of constantan the total cultivation level, profits increased 3% in optimum fertilizer consumption rather than current fertilizer consumption.
