摘要

Effect of seeding rate mixture from Egyptian clover (Trifolium alexandrinum L.) E.C. and barley (Hordum vulgare L.) B, N-fertilization levels and their interaction on quantity and quality of forage yield. Two field experiments were conducted during winter season of 2012/2013 and 2013/2014 in sandy soil at research and production station of National Research Centre, Al Nubaria district, Al Behaira Governorate, Egypt. The experiment included two factors first was five mixtures from seeding rates (24 kg EC/fed. – 50 kg B/fed. – 18 kg EC + 12.5 kg B/fed. – 12kg EC + 25 kg B/fed. – 6 kg EC + 37.5 kg B/fed.) and second factor was three N levels (30-45-60 kg N/fed.). Two cuts were obtained at 60 and 100 DAS. Results indicated significant differences between mixture rates for all studied characters in both cuts 60 and 100 DAS. Significant differences between N levels for all studied characters at 60 DAS, also, forage yield /fed. and DM% at 100 DAS. It can be introducing forage mixture of 18 kg EC + 12.5 B had balanced character in forage yield/fed., DM%, carbohydrate % and protein % at both cuts 60 and 100 DAS.
