Abstract

In Urmia county, irrigated wheat yield varies in different regions. The highest and lowest yields are attributed to Nazloo region (6.58 tons per hectare) and the lowest yield was for Silvana region ( 2.77 tons per hectare) respectively. So, the purpose of this study is analysis of management factors impact on irrigated wheat yield in Nazloo and Silvana regions of Urmia county. To this end, by questionnaire for 159 formers using proportionate (number of farmers) classified random sampling method, statistical tests have been done and flexible yield functions have been estimated. The results of the yield functions showed that the highest elasticity related to educational skills index and planning skills index belonged to Nazloo region and the highest soil conservation index and technical skills index belonged to Silvana sector. So it is suggested that the farmers increase the yield in the region by learning the new method, increasing the levels of literacy and participating in extension classes.
