Abstract :

Background and Objective: The challenge of costant development production in agriculture is the food security for growing population that increase the country food needs. The capability finding, lands regionalization and encouraging the producers for producting the strategic and high quality products with more add end- value result in optimum production according to offer and demand and decreasing the depandence. The edible oil have the most depandence amond basive materials so, cultivating the oily seeds with favorite quality and more efficiency that be compatible with climate conditions of country is as the most important effective factors for increasing the production operation. Method: In this research, first, the studied data of 7 meteorology station have been studied daily during the common years (1992-2010:1371- 1389) for 19 years statistic period. Then, the value information layers have been provided for Geographic Information System. The studied layers including the height, landuse, soil, frosty, effective and active growth term period. The present layers have been fuzzy by using fuzzy redundant, and then the weight of each layer have been calculated by AHP model.Then, the final regionalization of feasibility study for Canola cultivation have been provided. Findings: The results of study indicated that Kordeston province have fine cultivation capability for canola oily plant, so the 28% of lands in northeast and south east place in very fine limit. 38% of province lands place in fine limit and more of them observe in eastern half of province. 24% of province lands is in the medium limit and 10% of province lands place in weak limit, Generally, the eastern half of Kordestan province have more capability for Canola cultivation. Discussion & conclusion:  Based on the obtained results, the Kordestan province lands were divided in to four categories of highly suitable (7940.8 km2), suitable (10905.3 km2), moderate (6824 km2) and weak (2829.3 km2) lands on the basis of the environmental and climatologocal potentials for canola cultivation.
