Main target of this study was to classify land suitability for efficient use of agricultural land and achieve sustainable cotton production using Geographic Information System. The study carried out based on interpretation of aerial photographs with geological, topographical and land use maps. Soil map of the region were prepared using Geopedologic method. After preparing the soil map as a base map, land suitability classification for cotton determined using simple and parametric limitation method. Climate and soil requirements tables for cotton were been set. Results of the soil study indicated that the soils categories were Entisols and Inceptisols in the region. The study area was divided in 7 landforms. Soil horizons characteristic of profiles includes Ocric, calcic and cambic. Calculations showed that growth period is 170 days from 5th May till 25th October. The precipitation period is 90 days. The results also showed that the economic production of cotton is not possible in the whole area. On the other hand, due to unfavorable weather conditions, if land limitations be improved, a limited part of the study area will be relatively suitable for cotton. So the final class of climate limitation for cotton due to the temperature factor in the flowering and also relative humidity maturation stage will be class S2. Limitations of the topography factor that is exclusively distributed in the hilly areas can be seen in the small parts. Because of the soil texture and access to water and thus the possibility of further leaching of salts, the possibility of the cotton cultivation will be high.
