This research is one of the projects of the national plan of land suitability evaluation for important agricultural and horticultural crops in the irrigated plains, which has been implemented in all provinces. These projects was aimed to determine the land suitability for cultivating field and orchard crops in the studied areas, which is an essential element in preparation of the country's cropping pattern. This research is also dedicated to two provinces of Hormozgan and Bushehr. In the two provinces, the first phenological information, meteorological data and soil and land data extracted from soil studies of the region and digitized soil maps were collected. Land suitability assessment was carried out for 9 field and 5 orchard crops of Hormozgan province, with an approximate area of 157,000 hectares. In Bushehr province, land suitability assessment was carried out for 10 crops and 3 garden plants in an area of 101000 hectares. According to the results of the land suitability classification in Hormozgan province, in the highly suitable class (S1), watermelon with an area of about 4893 hectares, in the moderately suitable class (S2), tomato with an area of 6296 hectares, canola in the marginally suitable class (S3), each with approximately 15674 hectares, in the currently unsuitable class (N1), onion with 19664 hectares and in permanently unsuitable class (N2), sesame with 17656 hectares contain the largest area in the studied land. In Bushehr province, barley and wheat in the highly suitable class (S1) each with about 1100 hectares, in the moderately suitable class (S2), barley with an area of approximately 33724 hectares, and cucumber in the marginally suitable class (S3) with approximately 33600 hectares, in the currently unsuitable class (N1), sesame with 47453 hectares and in permanently unsuitable class (N2), tobacco with 100000 hectares have the largest area in the studied land. The results of the land suitability classification for horticultural products in Hormozgan province showed that, in the moderately suitable class (S2), mango with an area of about 6430 hectares, lotus in the marginally suitable class (S3) with approximately 14619 hectares, in the currently unsuitable class (N1), date with 11377 hectares and in permanently unsuitable class (N2), citrus with 25550 hectares have the largest area in the studied land. For horticultural products in Bushehr Province, date in the highly suitable class with an area of about 807 hectares, in the moderately suitable class (S2), lotus with an area of about 851 hectares, date the marginally suitable class (S3) with approximately 22920 hectares, in currently unsuitable class (N1), lotus with 27627 hectares and in permanently unsuitable class (N2) citrus with about 91575 hectares have the largest area in the studied land. According to the results obtained from this investigation, the priority of cultivating crops in Hormozgan province is watermelon, tomatoe, wheat, potato, onion, canola, cotton, corn and sesame. In Bushehr province, the proposed priority for plant cultivation is barley, wheat, watermelon, alfalfa, tomatoes, onion, cucumber, eggplant, sesame and tobacco, respectively. Also, based on the obtained results in this research, the priority of cultivating garden products in the studied areas of Hormozgan province is mango, date, lotus, guava and citrus. In case of Bushehr province's garden products, the priority of plants is date, lotus and citrus, respectively.
