Blue panic (Panicum antidotale) is a warm – season grass native to south Iran and considered as a major species of the tall grass sandy rangelands. It is succulent and nutritious in the young stage , but becomes fibrous and woody at maturity. Blue panicgrass has a vigorous seedling and is relatively easy to establish . It is highly productive the first years , but loses vigor in subsequent years. To its forage value , Blue panicgrass is widely used in areas where soil conserving practices are needed . This investigation was designed to achive major objective , to establish the response in tiller production of Blue panicgrass to clipping frequency and clipping regimes suitable for sustained plant .This study was conducted on Blue panicgrass species at Khuzistan sand dune experimental station . Four replication were included in a splite plot design . Clipping frequency was main treatment and clipping quantity was secondary treatment . Comparison of the 3 years harvest frequency has shown that harvesting submain treatment number 3 (clipped each 18 days ) superior to the other treatments . Over 3-year period , tiller per clone were , averaging 36 for that submain treatment . Higher clonal survival and tillers per clone on that treatment clipped ( each 18 days ) may have been due to slightly longer period after the last clip , which enables the plant to resupply storage tissues.
