Title

ASSESSMENT OF CROP LAND IN TEHRAN AND ALBORZ PROVINCES FOR RAPESEED CULTIVATION USING GEOGRAPHIC INFORMATION SYSTEM (GIS)

Pages

  27-41

Abstract

 Determination of land suitability for cropping purposes through evaluation of climatic, soil and topographic factors is of great importance for developing a sustainable agricultural system. In this research the land suitability of Tehran and Alborz Provinces for RAPESEED cultivation was evaluated using the Geographical Information System (GIS). The results of overlaid maps with application of the maximum limitation method based on climatic variables which are necessary for winter RAPESEED (active growth degree days from planting until frost period, active growth degree days from planting to flowering, active growth degree days from planting to harvesting of canola, average maximum and minimum temperatures during growing and number of frosted days in the study area) indicated that the most of the land in the study area (34.85%) in terms of CLIMATE is moderately suitable (S2) for RAPESEED cultivation. Approximately 30.17% of the land in the North and the Southeast of the study area is unsuitable (N) for RAPESEED growth and development. This occurs because the temperature reaches as low as -26oC in the Shemiranat and Damavand regions and -32oC in the Firouzkooh region during the rosette growth stage of RAPESEED and, therefore, not enough growth degree days in the rosette, flowering and harvesting stages are available. In the Southeast of the study area, with temperatures of 27, 30 and 35oC occurring at the flowering, packing pod and maturity stages, respectively, are harmful and, therefore, RAPESEED cultivation is not suitable. The results indicated that 18.51% of the land in terms of CLIMATE is suitable (S1) for growing RAPESEED. The results of overlaid maps with application of the maximum limitation method for CLIMATE, LAND USE, TOPOGRAPHY and soil variables also showed that approximately 83.12% of the land is not suitable (N) for cultivation of RAPESEED. However, climatic and soil constraints are important limiting factors for cultivation of RAPESEED in these areas. Thus, for RAPESEED cultivation, only 7.9% of the land in the study area is suitable (S1).
