Understanding potential and capabilities in desert areas and Identification and introduction of plants compatible with those conditions, it is very important to modify hard and brittle conditions and forage production. In this study, to identify and introduce suitable pasture species for planting and establishment with the aim of restoring vegetation in Bushehr Province, the species of Cenchrus cilliaris, Cymbopogon oliveri, Panicum turgidum and Sporobolus arabicus were used. For this purpose, during the spring of 1394, the seeds of the studied species were collected and cultivated in the second half of 1395. The traits included altitude, percentage of viability, canopy percentage and forage production in year and plant deployment rate. Data collected in a randomized complete block design were analyzed by SAS software and the means of the collected samples were compared with Duncan multi-domain test. Results showed that there was a significant difference between the species in the measured factors. The species P. turgidum, C. oliveri and C. cilliaris were respectively identified as the best species in the climate conditions of the Dashti district in Kaki. S. arabicus specie in some traits, it could have a significant statistical significance but was not meaningful in terms of deployment and compatibility.

Different plants have different effects on the characteristics of their surroundings, especially on the soil. Soil properties also have the different effects of these plants on them. In this research, the effect of capparis spinosa on the soil characteristics of three areas with different soil characteristics was evaluated. The under-floor soils of the capper plant in three depths of 0-30, 60-30 and 60-90 cm, compared to the non-vegetation soils, were taken in three different geographic regions with six replicates and a total of 108 depth samples, and in The laboratory measured some of their physical and chemical properties. SPSS software was used to analyze the data and to compare the measured characteristics with non-pairs F and T tests. The results showed that the effect of capper plant on the characteristics of saline soils is a significant reduction of salinity and soil salts, reducing SAR and simultaneously improving some of the characteristics of fertility, such as increasing the potassium available in these areas. Also, in soils with light and medium non-saline texture, significant increase in available potassium levels and SAR reduction were observed in the lagging soil.
