摘要

Today's excessive use of croplands and the resulting damages alongwith the ever-increasing demand for further crop productions have necessitated the best land management practices more than ever. Due to the current lack of any proper land management practices for Baghe region in Khuzestan Province, south-west Iran, a land suitability evaluation study for key productions of the region, including wheat, alfalfa, maize and barley, covering an area of 7000 ha was carried out in the region. Using the findings of the semi-detailed soil studies for this area, three soil families and eight soil series in two physiographic units were identified. Physiologic requirements of each crop were also determined and rated based upon the proposed method of Sys et al. (1991). The tables were provided by the Iranian Soil and Water Research Institute. Qualitative evaluation was carried out by means of simple limitation and parametric methods (Storie and Root Square Method) and comparing land and climate characteristics with crop needs. The index obtained for barley was higher in comparison to that developed for wheat, alfalfa and maize. After that the land indexes for wheat and alfalfa were higher in comparison to maize. The limiting factors in different crop yield in the region alongwith climatic variables included soil salinity and alkalinity, drainage and carbonate contents. From the two methods used i. e. simple limitation and parametric methods (Storie and Square Root Methods), the latter (Square Root Method) produced more realistic results in respect to the existing conditions of the region.
