Determination of land Production Potential for Wheat in Gotvand and Shoustar Areas, Khuzestan Province

Production potential of land for human food, especially wheat supply is limited and depends on environmental factors affecting production, such as climate, soil, landscape, and management. This paper examines these factors and provides guidelines for understanding the limitations of these factors and their role in the production were also investigated. The study area were in Aghili plain of Gotvand and Mianab plain of Shooshtar in Khuzestan. The result showed that land production potential for irrigated wheat in mian ab from 933 to 6023 kg/ha and for Gotvand is 2254 to 6687 kg/ha. The main soil limiting factors in both area were salinity, alkalinity, drainage and calcium carbonate limitations. predicted yield were compared with farmer wheat yield in both areas and showed coefficient factor equal 0.80 for Gotvand and 0.77 for Shoushtar. That means model can predict farmer yield with 80 percent in Gotvand and 77 percent of accuracy for Shoushtar.The reason of higher wheat yield in Gotvand to shoushtar is because of lower salinity limitations in Gotvand area.
