گزارش نهایی طرح بررسی اثرات میزان بذر بر عملکرد دانه و علوفه ارقام دومنظوره غلات در استان خراسان

The effects of different seed Rates on forage and grain Yield of barley cultivars and triticale as Dual purpose cereals was studied in a clipping condition. This Investigation conducted in Mashad Agricultural Research center in 1371- 72, 1372-73 and 1373- 74. This study was carried Ott in a splii plot design in base on R.C.B.D design Barley cultivars ( walfajre, Makuee and Rihane) and triticale ( Juanillo 92 ) as main plots and seed Rates (350, 400, 450,500 and 550 seed/ m2) as subplots were studied. the results Indicates that the effects of year over studied characteristics was significants. Becaus of good climatic conditions in the third Year of experiments the higest yield of grain, Harvest Index, no.of fertile ear per square meter and 1000 Kernel weight were obtained. There was no significant different between grain Yield of barley cultivars and triticale. Triticale had the higest hay and total dray matter. The upper harvest Index, No. of fertile ear per square meter and 1000 Kernel weight was belonged to Rihane. The effect of seed Rates on mentioned charactristics was no significant and so seed Rat of 350 seeds per square meter was a suitable density, and also favorable Tillering capacity of these cultivars, espicially after clipping componsate the reduction density. Therefore increase of seed Rate not only dident increase yield and other charaters it appears that it would not be economic.
