Range species forages have different quality and feeding value in different site and times. Therefore research carried out to Investigate of Plantago Coronopus Forage Quality at different phenological Growth Stages in Five Habitats of Golestan Province (Goomishan, soofikam, Sangar Tappeh, Inchehbroon and chaparghoymeh). Samples were collected  from two phonological stages (vegetative and seed ripening) and then  crude protein (CP), ether extraction (EE), organic mather (OM), acid detergent fiber (ADF) and lignin (ADL) were determined. Dry matter digestibility (DDM) and organic matter digestibility (DOM) of forages were determined using rumen fluid from buffalo by in vitro techniques. The results of chemical analysis indicated that CP, EE and ADF percent were significant differences in different sites (p<0.05). CP (%), DOD (%), DE and ME (mj/kg) in Chaparghoymeh was better than other site. In all sites, quality of P. coronopus were varied at two phonological stage and seed ripening (p<0.05). DM and ADF content were increased with phonological stages increasing, but CP, DDM, DOM, DE and ME of forage were decreased(p<0.05). CP percent at two growth stages are higher than its critical level (7%) for one animal unit maintenance. DE and ME amounts at vegetative growth stages are higher and at seeding stage are lower than its approximate amount of critical level for supply daily requirement of animal unit. In general, result shown that forage quality of rangelands were varied in different sites and this plant at vegetative stage can supply protein and a great part of energy requirement of different grazing ruminant groups (sheep and goat).
