< p>Knowledge management and benefiting from the experiences and knowledge experts in Iranian Pistachio farming will be a method in order to achieve the development of Agriculture and Pistachio gardening in Iran. The present study is based on a qualitative approach and grounded method theory. The research tool was based on interview with 22 members of the Rafsanjan Pistachio Producers Cooperative, and was conducted in three criteria of open (initial), core and selective. Open code includes 34 concepts and core code includes 4 major categories, including cost reduction, product quality enhancement, innovation and continuous improvement. Agricultural development was identified as the central criterion of the present study. In order to understand the experiences of growers in their own language, semi-structured interviews were conducted to provide solutions to develop pistachio agriculture and create a competitive situation. Thus, the interviews begin with general questions and are followed by the solutions of each grower. The interview questions are designed to transfer technical knowledge of the interviewees and achieve solutions in order to benefit from knowledge management in the development of pistachio agriculture in Iran. The findings of this study helps the presentation of strategies to develop agriculture and maintain the position of Iranian pistachio growers in competitive markets that will lead to greater profits. According to our research, establishing a powerful cooperative system could satisfy growers’ requirements and will lead to an expansion of agriculture in Iran. Additionally, our system could result into establish a more proactive farming society using knowledge management. Manuscript profile

The purpose of this study is to develop a model for knowledge management of Iranian pistachios based on the Knowledge Management for Development (KM4D) model. The knowledge of farmers and new scientific knowledge are complementary in terms of strengths and weaknesses. By combining the two, one can achieve the success that would not be achievable by using them on an individual basis of two. The present study is an exploratory mixed study. A study was designed based on the combination of library studies, documentation, and exploratory mixed studies to form a cross-sectional study in terms of data analysis and processing method, and correlational research. The statistical population of the research is divided into two parts: the qualitative section which includes 7 people and the quantitative part which includes 149 farmers, experts, specialists and experts in pistachio agriculture, and horticulture. Simple random selections are selected. To analyze the data in the qualitative part, the grounded theory method based on the KM4D model has been used. The quantitative part based on descriptive statistical analysis using SPSS software version 23 to generate relevant graphs, mean, median, and frequency table. Implementing knowledge management in agricultural organizations has a significant role in improving pistachio agriculture and horticulture development. It will result in reducing costs, increasing quality, innovation, and continuous improvement. The current study has presented a new model in knowledge management of Iranian pistachios agriculture, which will benefit from the quantitative and qualitative development of this agricultural product. The main application of this study is to increase added value of farmer's products. Manuscript profile
