520 _aTwo field experiments were conducted during the two winter seasons of 2000/2001 and 2001/2002 at Wadi Sudr Experimental Station. The aim of this study was to compare the effect of different carriers of slow release nitrogen fertilizer i.e Urea (46.5%), formaldehyde-coated urea (40%N), rock phosphate¬ coated urea (37o/oN), bentonite-coated urea (37%N), talic-powder coated urea (37%N) at the four following rates 0.0, 30. 50, 70 kg N/fed on some growth traits and forage yield of barley. The results obtained indicate that the use of bentonite and talic powder showed superiority over the other treatments in respect to plant height, number of tillers and leaves /plant, leaf area, leaf/stem ratio. Moreover, bentonite, talic powder and rock phosphate treatment gave the highest forage yield, that increase amounted32, 30, 26%for accumulated dry forage yield .On the contrary, urea formaldehyde depressed the accumulated dry forage yield by 25% of the normal urea. Raising nitrogen rates up to 70 kg N/fed significantly increased growth and yield of barley and the increases in the accumulated fresh and dry forage yield amounted 199, 211 % of the unfertilized treatment respectively The interaction effect between treatments was significant in fresh and dry accumulated yield and the highest were recorded with bentonite with 50 kg N/fed and talic powder with 70 kg N/fed.
