Establishment of Helianthemum lippii and Taverniera cuneifolia in Hormozgan province

Helianthemum lippii and Tavernieracuneifoliais are the most important broadleaf  plants of Hormozgan province, Iran. To investigate the establishment of these species, this study was conducted at the Watershed Management and Natural Resources Station of Dehgin (Hormozgan province) from November 2014 for three years. The three methods of seeding in farrow, pitting, and crescent catchment were studied in a randomized complete block design with three replications in SAS software. The results showed that there was a statistically significant difference between experimental structures, plant species used, and also the interaction of structure and species. A statistically significant difference was recorded for Helianthemum lippii and Taverniera cuneifolia at the level of 5%, for the crescent catchment structures, pitting, and contour-furrow at the level of 1%, and also for the interaction of structure and species at the level of 1%.  The highest percentage of species establishment was in the crescent catchment structure with 27.1% and the lowest was related to the pitting structure with 3.2%. Investigation of the interaction of structure and species in the rate of species establishement in different structures showed that the highest percentage of establishement was related to Taverniera cuneifolia with 31.2% in the crescent-shaped structure, after that, the highest percentage of establishment was related to Helianthemum lippii with 22.9% in the same structure. The lowest establishment was related to the contour-furrow structure with 2.1% for Taverniera cuneifolia and pitting structure with 2.1% for Helianthemum lippii. Based on the results of the present study, it is suggested that to successfully implement rangeland cultivation projects with Lippii Helianthemum and Taverniera cuneifolia in similar climates of Hormozgan province, the mentioned species should be planted in crescent-shaped structures.
