عنوان مقاله [English]
Hamedan province is one of the suitable areas for growing garlic, So that This product is considered as a source of income in this region. Due to traditional cultivation and And no use of new methods, productivity of production factors in producing this product are not acceptable. Since increased production by increasing the cultivated area is faced With limitations such as Water Resources limitation. Therefore, by increasing the productivity of inputs Particularly the water can be achieved by increasing production. In this regard, the study of the productivity of production factors is very important. Therefore, this study aimed to measure the productivity of production factors in two surface and sprinkler irrigation methods in garlic production in Hamedan province. The required data of this study were collected by a questionnaire from 145 of garlic farmers in Bahar and Hamedan city in 2017. In order to determine the proper yield function in both surface and sprinkler irrigation methods, the Transcendental and Translog function were used respectively. The results of this study showed that the productivity of all production factors, especially water in sprinkler irrigation system, is significantly higher than surface irrigation system. Farmers in sprinkler irrigation method are more logical in terms of water use. Physical and economic productivity of water in sprinkler and surface irrigation is 2.6, 1.76 kg per cubic meter of water and 128932 and 87146 rials per cubic meter of water, respectively. Thus, on average, the physical and economic productivity of garlic production in sprinkler irrigation is 48 percent higher than surface irrigation. Total stretch of production factors Showed that the sprinkler irrigation method has a high potential for increasing production compared to surface irrigation methods. garlic farmers use water, fertilizer and seeds optimally, but use chemical pesticides in both irrigation methods and Labor force in surface irrigation method More than the optimal amount of use. Farmers use water, fertilizer and seed optimally, but use chemical pesticides in both irrigation methods and the workforce in surface irrigation method More than the optimal amount of use. Therefore, in order to better utilize the factors of production and increase the profitability of the farm, it is necessary to reduce the use of chemical pesticides in both irrigation methods and to use less labor in surface irrigation method.
