الملخص EN

A field Crop experiment was executed at Al-Qurna site (75Km) north of Basrah city during winter season of 2012-2013 to study the effect of four levels of Nfertilizer on the yield of mixture of barley (Hordeum vulgare L.) with Egyptian berseem (Trifolium alexandrinum L.) which were (0,60,80,120)Kg/h and three seeding rates (40,80,120 Kg/h) from barley which mixtued with fixed rate of rate Egyptian berseem (40Kg/h) on by take three forage yield and quality by take three cutting and the results showed that: using high rate of N-fertilizer (120Kg/h) lead to significant increase of plant height of barley and number of tillers also number of berseem and green forage yield which reach 69.11t/h and increase of protein percentage while the dry forage yield did not differ with second level of N-fertilizer also using high rate of seeding (120Kg/h) of barley with 40Kg/h of berseem lead to barley and number of tillers also fresh and dry yield of forage which reached (73.45, 21.44 t/h) respectively and increase of protein percentage rate of seeding rate which were 18.16% by used 80Kg/h seeding rate of barley with 40Kg/h of berseem.
