Some trait such as plant height, leaf and stem weight in one sample of 50 g forage form each plot, ratio of leaf to stem and fresh and dry forage yield were recorded .Analysis of variance for collected data from forage yield (barley forage yield as well) and other traits were calculated. At the end of third year of study, combined analysis was done .Means comparison for planting dates proportion of alfalfa and barley and interaction and between planting date and proportions mixed by DMRT.
