Due to different management and climatic factors, a significant level of rangelands of the country is degraded quantitatively and qualitatively and an important part of its plants is in danger of extinction or their population has declined sharply. To create stability in these rangelands, range improvement and reclamation practices through selecting right species has a special priority. Therefore, regarding the results of research projects carried out in Booshehr province, this study was aimed to investigate the forage production of Helianthemum kahiricum accessions. The seeds of four accessions of the study species were collected from Chahake Ganaveh, Delaram, Mand and Naiband. The study was conducted in a randomized complete blocks with four treatments and three replications under field conditions in the Borazjan station. From the second year onwards, forage production was recorded each year. Data analysis was performed using SAS software and mean comparisons were done by Duncan’s test. Our results clearly showed that among the study accessions, Delaram could be used in range improvement and reclamation due to the forage production of 200 kg/ha and successful establishment.
