Although there is a tendency worldwide towards alternative methods in effectively managing weeds, use of herbicides to control weeds in conventional agriculture is still inevitable. With regard to externalities (through unsystematic use of herbicides) imposed upon environment, in the present paper it has been tried to study the willingness to pay of wheat farmers to plan for reducing the side effects of herbicides (in the form of different measures) and by use of a cross sectional data set related to wheat farmers in 2008 in Khorasan Razavi Province. A contingent valuation method was employed in the course of implementation of the study. To achieve the purpose, 180 farmers from different cities of the province were selected through random sampling method. Data were collected through questionnaire. Results showed that average willingness to pay of farmers to reduce externalities of herbicides is about 238733.3 Rials ha-1 which is higher than the cost of herbicides (150833.3 Rials ha-1). Also, by change in the choices of reducing externalities of herbicides on different environmental components, the level of willingness to pay of farmers increased. In addition, age, knowledge of farmer and ownership exert positive effects on willingness of farmers to pay to reduce the externalities of herbicides. Also, there is a significant positive correlation between education level along with type of ownership and average willingness to pay to reduce the environmental externalities of herbicides. Results indicate that the efforts of experts to produce herbicides with minimum negative side effects, taking into consideration the rate of willingness to pay in the system of pricing and in herbicide provision effective mechanisms for informing farmers are in the meantime strongly recommended.

Environmental effects associated with pesticide application have motivated the development of integrated pest management programs throughout the world. Advantages of the implementation of such a program like food security, biodiversity, consumer and producer security can be stated as economic value. Estimating the economic value of such programs can be helpful in identifying the benefits as well as their extensive applications. This study employs contingent Valuation survey to estimate farmers’ willingness to reduce three risk levels (high, moderate, low) in five environmental categories (human health, birds, aquatic species, beneficial insects and livestock). Using the environmental/risk criteria, pesticide active ingredients are divided by the environmental classes in conditions of application and non-application of Integrated Pest Management (IPM). To estimate the economic benefits, the physical risk assessment approach was combined with the contingent valuation survey results. Data were collected from 180 Farmers in Khuzestan province in 2009 using two step Random Sampling Method. IPM practices reduced the Agrochemicals’ hazards in all the environmental classes. The values of change in the environmental risks varied from 5 percent (human/low) to 57 percent (livestock/high). The economical benefits for 15 environmental classes varied from 315364 Rials (human/high) to 9596 Rials (human/low) per capita in a cropping season. The aggregate value of environmental benefits of IPM in Khuzestan within 2009 is estimated as 1140740 Rials per household. Relevant education in the context of awareness of farmers as well as adoption of standards along with relevant regulations for a limitation of toxic substances’ usage are recommended.

Producers and consumers’ price behavior were analyzed in chicken meat market in Fars Province. Monthly average producers and consumers prices from June 1997 to July 2008 were taken into account. Changes in the producer and consumer prices indicated that the prices follow an increasing trend with much fluctuations. Marketing margin has an increasing trend of violent fluctuations. The result of Granger causality test is indicative of bilateral relationship between producer and consumer prices. Generalized Autoregressive Conditional Hetroscedasticity (GARCH) was selected and estimated for an investigation of producer and consumer price behaviors. The results indicate a bilateral transition relationship between producer and consumer prices. Marketing margin isn't constant and market structure is uncompetitive, thus retailers as well as slaughterhouses asked additional profit in addition to the constant margin. This profit, is related to market power and incidental shocks, and is varied. During the study period, an asymmetric price transmission was confirmed on both the long and short runs.

On Farm Development Program is a strategy adopted for the development of Iran rice growing fields in the agricultural sector. SWOT method was employed for studying opportunities, threats, strengths and weaknesses of On Farm Development Program. Necessary data for the research was collected, through two sets of questionnaires, from 34 experts of On Farm Development Program in Guilan Province. Results indicated that opportunity for using suitable machines in carrying out agricultural activities (economical dimensions) is a most important factor. On the other hand the most important created threat is a redivision of farmland and creation of excessive boundaries in between (social dimensions). According to the experts, strength point of the plan is the most economical and environmental, its weakness points and the most environmental and institutional, and created opportunities are in economical and environmental dimensions, while created threats are in social and environmental dimensions. According to experts, views, the strengest point of this plan is the creation of independent pieces of other pieces for use of drainage canals and accessible roads (social dimensions) while the most important weakness point of the plan is a lack of instruction and advancement protection for informing agriculturalists (social dimensions). The most settlement situation of On Farm Development Strategy in Gilan province is in WT district namely in withdrawal or decrease strategy. In other words, activity levels in rice fields for On Farm Development Program must be a decrease, if not defeat of revenue methods that will happen in the future and then in the second stage, its settlement is WO district meaning that it is in change direction strategy showing that according to presented weak revenue and exciting opportunities, activity direction must be changed. The result of this research showed that according to experts’ views, in assessment of inner and outer agents of SWOT matrix, On Farm Development Program of rice fields have strong inner points and outer created opportunities. The results of this research indicated that a deletion of impermanent agents brings more sustainability than a creation of permanent agents and as a whole, one can coclude that, the project is comparatively sustainable.

The overuse of agricultural production inputs during recent decades with the aim of increasing crop yield the consequent deterioration of the environment are serious concerns that redouble the importance of more careful attention to the sustainability of farming systems and continuous production, accompanied by the conservation of natural resources. In this regard, family and rural production cooperative farming systems are considered as the most important and extensive agricultural farming systems. An identification of the type of more sustainable farming systems as well as factors affecting the sustainability of the system is a key to achieve rural sustainable development. This research was therefore conducted with the aim of examining and analyzing the sustainability of family and rural production cooperative farming systems in Agh-Ghala city. The research methodology employed in the study was a survey method and the required data collected and analyzed using questionnaire and cross-sectional/multi-stage stratified sampling during the 2008-2009 growing seasons from 190 farmers in the family group and from 150 farmers from the cooperative group in Agh-Ghala city. The research results revealed that 14.7 % of the farmers in the farming systems under study (whether family or cooperative group) were in a highly unsustainable state, 42.1% in unsustainable state, 22.1% in a partly sustainable state, 20.3% in a sustainable state and finally only 9% in a highly sustainable state. In addition, a comparison of the average sustainability of these two farming systems indicated that the sustainability level of the cooperative farming system in terms of different ecological, economic, and environmental dimensions is in a more appropriate standing than the family farming system. Also, the results of Path Analysis for causal explanation of factors affecting the farming system sustainability showed that the six variables "investment" "age of farmer" "level of participation" "size of farmland" "access to inputs" and "access to farm machinery" exert direct effects while the variables "access to agricultural information resources" and " farmers'' literacy level " indirect effects on sustainability.

Factors differentiating the successful and less competent dairy farms were identified, using data from 56 Shahriar dairy farms. Then, were determined the role and share of different factors, including management, efficiency and scale in the discrimination trend. In order to have the dairy farms classified into "successful" and "less competent" ones cluster analysis as based on different profitability indices was employed. Following a consistency test of the results of the indices, two logit models were estimated. The results indicated that production scale (herd size) is an important factor influencing the discrimination betweenthe two categories and shows a nonlinear relation with probability in success. Among the efficiency factors, feed efficiency and cow productivity are in positive and significant relation with profitability. Manager experience, education related to animal science, use of modern technologies and bank loan were among the most important managerial discriminating factors. Also, such variables as stability of herd combination, reproduction management and production diversification index are factors influencing dairy farm profitability.

Utilization of effective instruments in support of and to provide economic safety for active population in the agricultural sector and towards an increase in production is an indispensable necessity. Agricultural crop insurance is one of these instruments. The purpose of this paper is to investigate the factors affecting an adoption of agricultural crops’ insurance among apple growers in Semirom city and determine the most appropriate model. A survey was conducted using stratified random sampling. The mass of the sample was comprised of 205 apple growers. Data were collected through questionnaire from 166 adopters vs. 39 non – adopters. The results indicated that adopters of insurance in Semirom are of a more risk taking nature and have a better understanding and awareness of the advantages of insurance. Also the adopters have a more favorable worldview towards insurer’s apparent esteem. They are also in the possession of larger apple orchards. Multiplicity model was found as the best to make a distinction between adopters and non adopters of apple crop insurance. This model would be a better predictor of adopters vs. non–adopters.

The standing and importance of the subsector agronomy in regional economics as well as in strengthening of the social- economic processes in Zanjan province call for the means enabling one to make maximum use of the valuable capacities and potentials available in the above- mentioned subsector to enhance its development. One of those means to be strongly stressed upon is proper planning. Proper planning itself requires on identification and determination of the effective coefficients affecting the level of development in the subsector. Realizing the importance of the role of physical and developmental infrastructures in the development of the subsector agronomy, in the present study it is tried to make an evaluation of the effective factors as regards the credits allocated to water harness and transfer in the provinces,s rural areas. Other important affecting factors have also been taken into consideration and a final analysis of the obtained results made. Time series data released by Statistical Center of Iran Ministry of Agriculture, Agricultural Bank, Central Bank, Department of Energy, Meteorological Organization, as well as Budget and Planning Organization have been made use of in the ongoing research work. A combination of the methods of "Principal component Analysis" and "Numerical Taxonomy" was employed to find out the developmental level for any of the years within the time period of 1989-2008. The resulting figures as the dependent variable us. Factors effective in agricultural development as the independent variables were inserted in a regression model. This model came out to be indicative of the fact that the allocation of governments Developmental credits to "Water harness and transfer" in the rural areas of Zanjan Province has (with an exception of two time periods) positively and significantly affected the farming level of development. The result indicate that the combinatorial index of farming development has improved by 0.000717 units per 1000 billion Rials of increase in constructional credit investment in the field of "water harness and transfer". The closer the combinatorial index of farming development to Zero figure, the more developed the area is assumed to be.

The main objective followed in this study was to assess the rate of adoption of sustainable agricultural practices among extension volunteers in Qazvin Province. The study was a descriptive – correlational survey one. The population of the study was comprised of wheat farmers in province of Qazvin who acted as agricultural extension volunteers (N=365). From among these members, 185 were selected as sample of the study. Simple random sampling technique was employed to do the sampling. A questionnaire was designed for gathering the needed data. Content validity of the questionnaire was verified by a panel of experts in the fields of sustainable agriculture and agricultural extension affairs. A Cronbach’s Alfa reliability coefficient of 0.78 was obtained for the dependent variable of the study. A pilot test was conducted on a similar population from a different province to gather data for verification of the questionnaire reliability. Adoption behavior of the respondents was designated as the dependent variable of the study. The results indicated that a majority of the respondents were of either ''favorable'' or ''excellent'' adoption behavior. Muti-variant regression analysis indicated that about 68% of variability in the dependent variable could be explained by respondents’ education level, and as well, by the extent of their irrigated wheat farming land.
