بررسی تعیین نسبت مطلوب آمیختگی بذر در کشت توام لگوم و گراس

There are low fertility reglands with Mediteranian Climat at the south of area of Mazandaran provience. More grazing of local animal and also enterance of animals from winter quarters regions cause to desteraction of these rangelands. This project had done to improve ultilization of ranzgelands. This plan carried out in split plot design at four replicaition in four years .Main treatment were two species of grass ( Lolium perrenne and dactylic glomerata)and one species of Legum (Onobrechia radiate). Secondry tereatment were different ratio of legume and grass seed including 20, 30 and 40 percentages of legume and pure seed planting of legume and pure grass. Comparison factors were included species density, vegetation cover, basal diameter and dry forage prodaction. These factors were comprised every year. Results showed that twin planting of legume and grass is influenced increasing forage prodaction. Twin planting of dactylic and 40 percentages Onobrichis had the greatest forage yeild. Forage average was 3300 kg Per hectar Key words; twin planting of legume and grass, forage, yield
