Agroecological Zoning of Sugar Beet Cultivation Based on Soil Nutrients and Climatic Conditions (Case Study: East Azarbayjan Province)

At present, agriculture is one of the most important economic sectors of the country and that it can be said that economic growth is not possible without agricultural growth. Each agricultural product requires specific climatic and environmental conditions. This study was conducted to evaluate the environmental capabilities of East Azarbaijan province for growing sugar beet (ArcGis).

The data have been studied in consist of annual precipitation and raining of growth duration, temperature, evaporation, relative humidity, sunny hours, number days without freezing and hence height, slope, direction and depth of soil. The used of suitable ecological condition of sugar beet cultivation, production information layers and each series of data were valued and classificated that combined by GIS area and analysed with using Multi Criteria Decision Analysis (ranking, rating and analytic hierarchy process).

The results showed that the environmental capability of sugar beet cultivation plays an important role in the province of East Azarbaijan, and the factors affecting the climatic factors play an important role. It should be noted that in the overlapping method, temperature and precipitation factors play the most important role. Particularly, the role of precipitation is the highest.

The final results show the fact that climatic elements and factors
 Together, they play an effective role in the process of assessing the environmental capabilities of sugar beet cultivation. The share of each of the climatic elements and factors during the growing period of the studied crop is not the same. By adapting the effective layers in the sugar beet planting process in GIS environment, it is possible to identify suitable areas for planting this crop.
