تاثير ميزان بذر و فاصله رديف كاشت بر عملكرد يونجه يكساله M.SCUTELATA در شرايط ديم

The effect of the seed rate and row distance on the yield of annual scutetlata under the dry farming condition

M. scutellata is one of Ihe most important annual fodder botans of leguminous plants which because of its large grains capable of a high fodder potentially. It is of a special importance in nutrition of live stock. The alfalfa can be tilled periodically along with other cereals in the fallow lands in addition to producing a considerable amount of fodder it may prevent soil erosion and cause and increase in nitrogen and organic material of soil and improve its physico chemical properties. In different laboratory trial was made in station of agronomy research center of Khorramabad in split split plot formats on the basis of RCBD with Breplication during two years of farming in 1994 and 1995. in this trial treatment row spacing of 30, 40, 50 cm in main plots, and seed amount 5, 10-15 and 20 kg/ha in sub-plot. The test showed row spacing of 30cm over row proportion of 40 and 50 cm and seed amount of 20 and 15 kg/ha over 5 and 10kg/ha. The greatest efficiency of grain and pod was preserved in row spacing of 30 cm and seed amount of 10kg/ha with yield of 503 and 1336 kg/ha seed and pod.
