AbstractA field experiment has been conducted at the agricultural second research station affiliated to College of Agriculture / University of Al-Muthnna , located on Euphrates River in the Al-Bandar village southwestern province of Al-Muthana (800 m away from the city of Samawa/ Al-Muthana Province) during the winter season of 2015 to 2016 in order to study the effect of different amounts of seed oats Avena sativa L. (0, 40, 80, 120 and 160) kg. h-1 with a one amount of seed for Medicago sativa L. (40 kg. h-1)] and four levels of nitrogen fertilization (0, 40, 80 and 120) kg.h-1) on the growth traits and some vegetative traits (high plant and leaf area and weight of leaves and number of branches) and yield green forage for a mixture of forage alfalfa and oats, and three cutting. Applied experience manner split plot, according to randomized complete blocks design (RCBD) with three replications.
The results showed moral superiority the third for cutting recorded by using the seed mixture for (40 alfalfa :160 oats) kg. h-1 higher averages of plant height (55.22 cm) and the number of tillers (1058.65 tiller. m-2) and leaf area (98.37 cm) for oats compared to that obtained jet at the highest qualitative weight (509.74 g. cm-2) as recorded at the amount of alfalfa seed (40 kg. AH -1) the highest in the third cutting plant height (56.36 cm) and leaf area (207.50 cm 2. plant -1) and the number of branches (1477.84 branch. m -2) While recorded the amount of seed (40 Alfalfa: 80 Oats) kg. H-1 holds the highest green fodder when the third cutting has average of (58.21 tons). H-1 As for the effect of nitrogen fertilization level have won 80 kg. E -1 highest averages for all vegetative traits studied and yield green fooder to plant oats and alfalfa in the third cutting as well as the attainment of the highest averages in the leaf area of Chauvin specific weight of leaf alfalfa forage in the mixture when nitrogen fertilization is not added (control treatment) .).
