A research on the effect of different mixture rotios in borley + hairy vetch mixtures which were growned as winter inter crops in Diyarbakır conditions

This resarch was caried out in 1996-1997 cropping season in Dicle University Faculty of Agriculture Crop Science Research Area according to Randomized Block Design as 3 replicates In the research effect of different mixture rates ( % 100 Barley, % 100 Hairy Vetch, % 80 Hairy Vetch + % 20 Barley, % 75 Hairy Vetch + % 25 Barley, %66.6 Hairy Vetch + % 33.3 Barley, % 50 Barley + % 50 Hairy Vetch ) on yield and yield compenents were investigated; the highest fresh crop and dryed crop yields were obtained from % 100 barley, the least fresh crop and dryed cfep were optained from % 100 Hairy Vetch. In barley + hairy vetch groups, fresh and dryed yields were higher than control group ( % 100 hairy vetch ). In the ligh of this result, to increase hairy vetch yields, it should be planted with barley. Heights of hairy vetch and barley were not effected from different mixture ratios.
