The present study was conducted with the aim of designing a sustainable marketing model for the development of sustainable agriculture in the country using the data method of the foundation.

In this research, a qualitative research method has been used, which is a combination of the foundation data method and Delphi. . To investigate this goal, 15 people were selected by snowball sampling method for interviewing experts from the Ministry of Jihad-e-Agriculture in the export of agricultural products, and information was collected through in-depth interviews. Then, after identifying and categorizing the factors, the Delphi method was used to measure the validity of the model and variables.

Foundation data method was used for analysis. First, the initial coding was done and 84 codes were identified, and in the next stage, by applying changes (merging and deleting), then in the second stage, 32 concepts were categorized, and finally the known concepts were classified into five categories. Delphi results were examined in two stages and by removing and adding concepts, 32 were identified.

Therefore, the results show that the proposed model included economic factors, social factors, marketing factors, environmental factors and consumer-related factors and considered different aspects and in each of the identified components to the subcomponent. They also noted that in order to better implement sustainability in marketing, it is recommended to pay attention.

One of the most important economic indicators in the process of agricultural production is efficiency index. Due to the increasing competition and complexity of economic relations between production units, today measuring the efficiency of production, especially in livestock units to create the necessary planning and make optimal decisions in the management process of such units is of great importance. The aim of this study was to evaluate the technical, allocative and economic efficiencies and determine the factors affecting them in industrial farms in Kurdistan province.

The data of this research is related to the year 2019, in which statistics and information were collected through documentary study and face-to-face interviews. In this study, Deap 2.1 and Eviews 9 software were used to analyze the performance and determine the factors affecting them. To design the data envelopment analysis model, the main variables used in the study, including herd size, feed and concentrate, manpower, health, milk production and livestock manure production and the sum of different incomes were determined. The efficiency of industrial farms was evaluated in the framework of technical efficiency with constant return to scale, technical efficiency with variable return to scale, scale efficiency, allocation efficiency and economic efficiency. Performance calculations were performed assuming the minimization of production costs in the form of performance of industrial farms in Kurdistan province and the results were obtained annually. To determine the factors affecting the amount of performance obtained, Tobit regression analysis and parent statistics were used.

The results showed that technical efficiency with constant efficiency compared to the scale is 0.814 and with variable efficiency compared to the scale is 0.943. The scale efficiency of these livestock units was calculated to be 0.859 in which 22 dairy cattle breeding units with incremental returns to scale and 2 units with decreasing returns to scale were reported. The amount of technical efficiency in general was calculated as 0.824, allocation efficiency as 0.818 and economic efficiency as 0.680. In the general evaluation, milk production efficiency in Bijar city had the highest and in Qorveh city the lowest amount among other cities of this province. Decreasing the age of managers and increasing household manpower in technical efficiency as well as decreasing age and increasing fixed and current investments in economic efficiency had a positive and significant effect.

In general, in Kurdistan province, in terms of technical efficiency of 34%, allocation efficiency of 14% and economic efficiency of 24%, dairy cattle breeding units are operating at an efficient level and the rest of the units are inefficient. Given the conditions of farms and the current state of the Iranian economy in the short term, it is better for livestock units to reduce their herd size by selling older dairy cattle and native heifers and optimally reviewing the supply and allocation of production inputs. Do the necessary.

In order to optimally use the inputs, the efficiency of economic units is of great importance. The purpose of this study is to investigate the technical efficiency and economic value of some traits of production, reproduction, survival and growth of Holstein cows in Pars agro-industry. For this purpose, required information including: manpower, cattle population, feed consumption and milk production quantities were collected from Pars Livestock Unit by documentary study, observation and face-to-face interview and their efficiency was calculated based on production and economic performance. The variables used in the research include herd size in terms of head, feed and concentrate in terms of weight, manpower in terms of men per day, health in terms of number of days per day, milk production and production of manure in terms of kilograms and incomes in Rials, which include Income from milk sales, Rial value of livestock manure produced, income from sales of voluntary and forced elimination of livestock, income from sales of bulls and heifers in dairy farms were examined. Deap 2.1 software was used for performance calculations. Optimal decision was calculated numerically by a iterative method using compecon toolbox in MATLAB program. Probability of pregnancy in the first, second, third and higher lactation periods based on data analysis and using logistic regression and GenMod procedure of SAS software Obtained, the results showed that the average of technical efficiency with constant efficiency compared to the scale was 0.83; the average efficiency with variable efficiency compared to the scale was 0.86 The scale efficiency of this company was estimated to be 0.96. The amount of technical efficiency in general was 0.83, allocation efficiency was 0.87 and economic efficiency was 0.72. This unit was efficient in March in terms of types of efficiency, which means that during this month, in addition to consuming a certain amount of product produced with a minimum of inputs, the minimum costs are also considered in the composition of inputs, so the unit in this month was technically, allocative, economically and economically efficient and has a constant return on scale. Also, the highest economic value in non-optimal conditions in survival, reproductive, productive and growth traits, and also for survival rate after weaning, first calving age, milk fat and body weight of adult animals was equal to 234297.30, -41835.16, 128664.12 and 454227.93 Rials, respectively. In optimal conditions, the highest economic value for survival, reproduction, production and growth traits was related to the set of traits of production lifespan, and the calving interval, milk fatproduction and daily weight gain before weaning were estimated at 4594.88,9084.67, 1582264.09 and -1464.87 Rials, respectively. The reason for the difference in economic values of traits in optimal conditions compared to non-optimal conditions is due to the application of optimal livestock replacement strategy, so that the farmer's policy in eliminating and replacing, affect herd profit.

One surefire way to increase income and profit is to pay attention to the viability of the dairy cow and increase the efficiency of each livestock unit. The purpose of this study was to determine the efficiency and effective factors on optimal herd life in dairy cows with dynamic data envelopment analysis and planning model in Ardabil city.

The data of this study were related to 1397 time series of dairy farms in Ardebil city which were analyzed by system analysis method, economic system of dairy herd and income and cost components, and each of these components was subdivided into other sections. Then, using mathematical models, we simulated a bioeconomic model and optimized it with the help of the Matlab software Compecon toolkit. The dairy cattle were described with state variables including lactation period, milk production capacity and different gestation states. In order to design data envelopment analysis model, several inputs and outputs in the production process were studied. The main variables used in the study included, herd size by apex, feed and concentrate in kg, manpower by day, health by Frequency of milk, milk production and livestock manure production per kg and total income were determined. And Deap 2.1 software based on minimizing the amount of input per unit of product was used for performance calculations.

Optimal herd life (from first calving to elimination) was 4.55 years under optimum conditions. The results also showed that the technical efficiency with constant return to scale is 0.719 and with variable return to scale equal to 0.899 and scale efficiency was calculated to be 0.888. The overall technical efficiency value was 0.99, allocative efficiency 0.583 and economic efficiency 0.579.

The effect of heifer price, milk price and discount rate on optimum lifespan showed that with increasing heifer price, milk price decrease and discount rate increase elimination percentage decreased and optimum lifespan increased. The results of data envelopment analysis showed that in terms of variability of efficiency relative to scale, increase in herd size and health costs and decrease in forage, concentrate and labor costs, respectively, 14.18, 0.83 , 2.8% and 5% result in inefficient herds being maintained by maintaining levels. Therefore, in order to make an inefficient unit effective, changes must be made to the inputs and outputs of that unit. By specifying the differences between the inefficient and inefficient units, appropriate strategies are designed to eliminate the gap between them.

Efficiency is one of the most important factors in productivity growth, especially in agriculture. The purpose of this study was to measure the technical, allocative  and economic efficiency and to identify the factors affecting them in dairy cattle stations of Moghan agro-industry company. The data of this research were gathered in 2017 by documentary study, observation and interview. In this research, Deap 2.1 and Eviews 10 software were used for analyzing performance calculations and determining effective factors, respectively. In order to design a data envelopment analysis model, the main variables used in the research included the herd size per head, feed and concentrate in kilograms, manpower in terms of man-days, hygiene per day, milk production and manure production in kilograms and total revenues were determined. Efficiency calculations were carried out with the assumption of the daily operation of milk production stations in the form of firm performance and the results were obtained daily, monthly and annual. Tobit regression analysis and parents' statistics were used to determine the effective factors on the amount of efficacy. The results showed that the technical efficiency with constant returns was 0.844 and with the return on the variable of 0.962. The company's scale efficiency was 0.918, in which 16 days performance of the company was recorded with a slower return to scale and 349 days with incremental returns to scale. The technical efficiency value in the general condition was 0.901, the allocation efficiency was 0.845 and the economic efficiency was 0.761. In general, milk production efficiency was the highest in January and the lowest in April. Factors affecting the amount of technical efficiencies of feed and concentrate and health variables. The effect of feed and concentrate in livestock diets and the level of health has been negatively affected by technical efficiency. Effect of feed and concentrate variables on negative economic efficiency and positive health variable. In terms of the effectiveness of different efficiencies on the income of milk production, technical efficiency and allocation had a negative effect and economic efficiency had a positive effect.

The purpose of this paper is to investigate the factors improvement of sustainable livelihoods from the perspective of local people of Ardabil County. First, factors affecting effectiveness improvement of sustainable livelihoods in the study area were identified from the perspective of local elites using semi-structured interviews. To achieve this goal, 35 residents of studied region were interviewed individually with college education and at least a bachelor's degree. In the second step of study, in order to understand and analyze rural communities' perspective of and their theoretical agreement degree with the results of the first step, 39 identified causes were the questionnaire design basis by Likert method. It can be said that studied population in this study consists of all villagers living in rural areas of Ardabil County in 2016 (N= 85053), among which 383 persons were selected as statistical sample using Cochran formula. In order to analyze the data, factor analysis model was used and the results of this model showed the most important factor improvement of sustainable livelihoods from the perspective of local people in studied region includes four components (entrepreneurship and fortification of economical infrastructures, support of demand- side and governmental interventional action, fortification of social capital and social empowerment and environmental management and fortification of physical infrastructures) that explained variance and the cumulative variance by the five factors 60.66. And finally, practical suggestions have been presented according to the results of the study.

More than one decade has passed since the significant and extensive emergence of organic agricultural concepts on international level. Rapid and serious loss of vital agricultural resources due to erosion, salinization of land, desertification, extinction of species and environmental pollution is among the world's major concerns. The main cause of such a concern may include indiscriminate use of pesticides, chemical fertilizers and agricultural implements, and the expansion of mechanized cultivation. According to the philosophy of sustainable agriculture, farming systems should be established based on justice and protection of natural resources. Such systems reduce environmental pollution, maintain agricultural productivity, and improve short-term and long-term economic ability and their quality of life. Due to continuous cultivation of garlic and lack of attention to the protection of productive resources over the past decades, we have witnessed a number of problems regarding environmental degradation. The use of pesticides and fertilizers in Hamadan province has been manifold compared to other Iranian provinces. This has been partly due the lack of awareness of factors governing farmer's interest in accepting organic garlic cultivation and sustainable agriculture, and lack of understanding of the mentioned factors in organic agriculture on the part of agricultural experts. Thus, this research, first and foremost, aims at the identification of factors which may affect the willingness of farmers to adopt organic cultivation of garlic in the province, followed by the correct procedures of natural resource management.
THEORETICAL FRAMEWORK: Several schools of thought exist on how to interpret the concept of sustainable and organic agriculture. Although there are major differences between these schools, they all agree that the present condition of agriculture is not sustainable. There are major differences between current and sustainable systems of agriculture. So far, there have been various definitions for organic agriculture. Some think of it as one of the most important agricultural systems for the production of healthy food free of any chemicals. Simply put, organic farming is a kind of agriculture in which consumers may easily use their products and make sure they will have no health problems derived from hormones and pesticides in products. Generally speaking, organic agriculture is not only the exploitation of resources based on purely economic criteria, but it also encompasses emphasis on sustainable production which does not harm basic resources, guarantees the rights of future generations and considers other aspects such as balanced distribution of food, food security, lack of environmental degradation and the use of collective measures. It should be mentioned that Iranian agriculture sector has been affected by inappropriate overuse of external inputs and unsustainable use of agricultural productive resources. The analysis of the present condition of Iranian agricultural sector clearly shows that agricultural systems used in Iran and other Third World countries are based on western patterns of agriculture, which all put emphasis on the use of external inputs.
This is an applied, descriptive and non-experimental research. This field research was a cross-sectional survey conducted between 2012 and 2013 crop year. Regarding it paradigm, the research falls into the realm of quantitative research. The research population includes all the producers of garlic in three regions including Hamadan, Touiserkan and Bahar, all located in Hamadan province. Simple random sampling method was used, and the size of the samples included 163 famers. To collect the data, a questionnaire was used. The content reliability of the questionnaire was evaluated by the assistance of a number of professors of Agriculture College of Mohaghegh Ardabili University. A preliminary test was conducted to obtain reliability, and Cronbach's alpha for different sections of the questionnaire were calculated between 0.72 and 0.83.
The results of economic factors rating showed that three variables including contracts request, the availability of manure in production and demand for organic garlic were respectively the most significant factors affecting farmer's interest in initiating organic garlic cultivation in Hamadan province. Based on the results of ranking social factors, the availability of insurance in the production of organic garlic was the most important factor affecting farmer's interest in initiating organic garlic cultivation. Generally speaking, the results showed that several variables such as demand for organic garlic, the availability of seed for organic garlic production, production costs and organic garlic market had a significant relationship with farmer's tendency to accept organic garlic cultivation in Hamadan province. According to the findings, farmer's conservativeness negatively affected their willingness to cultivate organic garlic. It is proposed to hold exhibitions, make TV/radio programs and distribute brochures to inform people about the benefits of healthy products and the disadvantages of chemical products. Thus they will be more willing to buy organic products. The required inputs should be also provided by government in order to ease farmer's access to such inputs. It is also suggested that a few farms be established by Jahad Keshavarzi Organization in different regions in order to make farmers more familiar with this type of agriculture.
