Feasibility of using different modern irrigation systems for wheat cultivation land (case study of Nahavand city)

This research was conducted to study suitable agricultural lands in Nahavand region that have the ability to implement pressurized irrigation systems. Questionnaire was the main tool for collecting information required for this research. Cronbach's alpha coefficient of the questionnaire was 0.65, which indicates its acceptable reliability. The statistical population is the owner of favorable agricultural lands (wheat) in the villages of Hamadan province. By random sampling, Nahavand city was selected from nine cities of Hamadan province and thirty villages were selected. Among the wheat farmers in these villages, the farmers who used the pressurized irrigation system to irrigate their wheat fields, the sample size was 379 using the Cochran method. Selected farmers were also randomly selected. In this research, in the first stage, a library study was conducted by referring to the documents available in the relevant departments, published articles, and review of relevant scientific findings. In the second stage, a hypothesis test and a method for selecting an irrigation system were performed. It was presented under appropriate pressure taking into account physical, socio-economic, and environmental criteria. The results of testing the research hypotheses showed that from the perspective of the respondents, the cost of consumption inputs in creating and using the type of pressurized irrigation system and the economic situation of wheat farmers, climatic conditions (climate, land topography, soil , quantity and quality of water in the study area) and study of individual and professional characteristics (age, level of education, land ownership, amount of land under irrigated wheat cultivation, and annual income) in selecting a pressurized irrigation system at a probability level of 1% was meaningful and positive. In the second part of the study, it was found that the highest score was obtained by the solid set sprinkle irrigation system and the portable sprinkler irrigation system.
