In the past decades, several development schemes have been implemented in the country, one of the most important projects, the development plan of orchards and the network of pumping stations for water. Due to the fact that many of these schemes have failed, the present study was conducted with qualitative approach using a grounded theory to the pathology of the project of the water pumping station of Harsin Pasar village. Data were collected using a deep interview, focus group and direct observation of the researcher, which analyzed the data in two stages of open and axial coding. The study population comprised this research expert involved in the project and the exploitation of Pasar village. snowball in the second stage to achieve theoretical saturation and conceptual richness of interest. The failure of the project was the main issue and phenomenon that researchers had repeatedly dealt with in reviewing and refreshing their field notes. Also, in this study, using the Parpostpaid model of Ali conditions (poor and inefficient planning, organization and poor recruiter of the project, etc.) , The underlying conditions (low social capital of Pasar people, low human capital, pasar people, inappropriate infrastructures and natural capital in the village, the dependence of locals to the state, and...) , The intervention conditions (the benefit of local authorities and powerful, lack of attention to the diversity of income during the implementation of the project, the contractor's commitment to their obligations, the lack of attention to the needs, demands and values of the local population and the prolongation of the project), Strategies (changing the Advisory team, changing the executive team and using the experienced staff, The change of design pattern from gardening to horticulture and agriculture compilation pattern and the consequences were analyzed.

The goal of study was to evaluate promising alfalfa cultivars for drought stress and identify the most tolerant and superior cultivars for drought stress.  

The experiment was conducted as split plot based on randomized complete blocks design with three replications in the East Azarbaijan Agriculture and Natural Resources Research and Education Center during three cropping seasons (2016-19). In the main plots, the irrigation factor was applied at three levels - at the first irrigation level only to the end of the first harvest, at the second level irrigation until the end of the second harvest, and at the third level irrigation until the end of the third harvest (complete irrigation). The second factor was six cultivars and alfalfa ecotypes.  

The effect of irrigation levels was significant for all measured traits. The fresh and dry matter yields of the studied genotypes were affected by irrigation levels and decreased significantly. Water stress significantly reduced plant height at first and second levels of irrigation 23% and 17%, respectively. Water stress, also significantly reduced the number of stems at the first and second levels of irrigation 34% and 30%, respectively.  

The responses of genotypes for dry matter yield were similar as fresh forage yield. In conclusion, synthetic and Azar cultivars and Varzghan ecotype were the most suitable cultivars for deficit irrigation conditions and are suitable for cultivation in low irrigation conditions in Tabriz plain.
