The main objective of this research is to evaluate and compare land suitability for different irrigation methods based upon a parametric evaluation system in an area of 49 622 ha in the Shoibieh Plain, SW Iran. The obtained results showed that for 18 804.64 ha (37.9%) of the study area surface irrigation method was highly recommended; whereas for 36 046.49 ha (72.6%) of the study area a sprinkler irrigation method would provide to be extremely efficient and suitable. The results demonstrated that by applying sprinkler irrigation instead of surface and drip irrigation methods, the arability of 48 805.43 ha (98.3%) in the Shoibieh Plain will improve. The comparison of the different types of irrigation revealed that sprinkler irrigation was more effective and efficient then the drip and surface irrigation methods for improving land productivity. It is of note however that the main limiting factor in using sprinkler irrigation methods in this area was calcium carbonate content.
