Abstract :

Considering the importance of mineral elements in nutrition of grazing livestock in the range and changes in the amount elements phenological stages of in the plants, awareness ranchers and range managers of these changes for planned correct entry and exit livestock and meet the needs nutritional of grazing livestock range at different times grazing season  is essential. In this study amount  six macro elements Ca, Mg, P, Cl, Na and K, and five micro elements Fe, Cu, Zn, Co and Mn, in eight range forb species Prangus uloptera, Medicago sativa, Lotus goeblia, Trifolium montanum, Sanguisorba minor, Stachys inflate, Melilotus officinalis and Ferula ovina used for sheepat vegetative, flowering and seeding stages were measured. To determine effect reciprocal of  species and phonologic stage, two – way variance analysis were used, and where the species and phonological stage interaction was significant, the Duncan test was used. The results showed; with advancing stages of plant growth, amount macro and micro elements were decreased, and between amount of Zn, Cu, Mn, P, Cl, K and Na eight species studied in different phenological stages was not significant difference,            but between amount of Mg, Ca, Fe and Co eight species in different phenological stages there was significant difference in the level of 99%.
