Abstract
The purpose of this study was to determine the Evaluation of different cutting intensity on some attributes of Teucrium polium and Helichrysum globiferum Gharebagh key species. In this first region and two key area of half hectare in area Gharebagh and in the first year and was grazed, and fencing. Selected and removed from any of 0, 25, 50, 75% and control is exercised (a basic 10 treatments). Monthly by the clipper and the area is grazing season. Effective utilization of changes in the phenological characteristics, forage and seed production, vitality, mortality and other characteristics of selected plants species were studied. Finally, the combined analysis of data from yield and vigority with a split plot design in SAS software was analyzed. Results of studies of the effects on forage production and harvest of T. polium and H. globiferum Gharebagh species studied showed that effects of different levels, different years, and their interactions on the production level is a significant percentage (p<0.01). This shows that in different years with different weather conditions of production are different. The research findings can be taken as authorized by the 50% cutting intensity for the T. polium and 25% for H. globiferum are suitable.
