The existence of irregularity in the ownership and pattern of agricultural land distribution is one of the most important challenges to sustainable agricultural development, which can lead to increase production costs, wasteful time for farmers, and reduce production efficiency. Therefore, the present research was carried out with the aim of analyzing the arable land fragmentation in East Azarbaijan Province so that by identifying these impacts, could be suitable solutions proposed for coping with arable land fragmentation. The statistical society of this research is the farmers of the agricultural sector located in East Azarbaijan province (N=212926). The sample size was estimated using Cochran's formula of 380 people. They selected by stratified sampling method. The research instrument was a questionnaire, that its validity confirmed by a group of faculty members at Tehran universities and Gorgan Agriculture University, and experts in agricultural lands working in Land Affairs Organization of Iran. The reliability of the questionnaire was measured by Cronbach's alpha coefficient: economic impacts=0. 81, social impacts=0. 91, technical impacts=0. 75 and management impacts=0. 86. The results of prioritization of impacts of arable land fragmentation showed that the most important effecs of arable land fragmentation were: increase of the problem of water division and its transfer to the other farm, increase of production costs, and decrease of productivity of production factors, increase in transportation costs, and the waste of time in the rebellion to various parts. Also, the results of structural equation modeling showed that economic impacts (with factor load of 0. 87) were the most effective outcomes among the impacts of arable land fragmentation.
