AB  - In the present study, regions favorable for the cultivation of canola seeds were determined using the geographic information system. Initially, for each of climatic needs of canola, one separate layer was virtually prepared with the help of the geographic information system. These layers included the layer of rainfall throughout the growth period, layer of frost, the layers of mean minimum absolute temperature, mean maximum absolute temperature, mean maximum temperature and mean temperature of the growth period, the layer of sunshine hours and physiographical layers of the earth such as topography, slope, land use and soil depth. Finally using a combined weight factor model, the regions favorable to canola seed cultivation in Ardabil province were mapped. Based on the analysis of the final maps, the land area of the province suitable for cultivation was determined: 9.85% without any limitation, 18.36% with little restriction, 16.70% with moderate restriction, 30.66% with fairly severe restriction and 23.43% with very severe restriction.
