Determining the Allowable Use for Dactylis glomerata in Semi-Steppe Rangelands of Iran

Current research was performed in selected sites of semi-steppe vegetative region including Alamot (Gazvin), Saral (Kurdistan). Dactylis glomerata is a key and palatable species, having a considerable portion in rangelands production of the mentioned flora. For this purpose, 40 similar D. glomerata were selected in each site. Selected species were exposed to different harvesting intensities of 25, 50 and 75 percent and zero as control group. Data were analyzed by SPSS and MSTATC and Duncan’s Multiple Range Test was used for mean comparisons. Results clearly showed that a harvesting intensity of 25-50% could be recommended as the best allowable use for D. glomeratain this vegetative region and other similar areas.
