Abstract
This investigation was conducted at two locations (Ismailia) representing East Delta and (Nubaria) representing North West Delta during 2003/2004 and 2004/2005 growing seasons to investigate the effect of seeding rates and nitrogen fertilization on forage yield and quality of berseem-ryegrass mixture. Results showed significant variation in the total fresh and dry forage yields due to ryegrass seeding rates and N fertilizer rates at Ismailia in the first and second seasons, respectively. No significant differences were recorded in the total fresh and total dry forage yields at Nubaria in the first and second seasons, respectively. The highest total fresh and dry yields were generally obtained with the seeding rate of 20 kg berseem/fed. and 12 kg ryegrass /fed. and adding 60 kg N/fed. The highest CP and ash % and the lowest CF% were generally obtained with the seeding rate of 20 kg berseem /fed. and 8 kg ryegrass /fed. and adding 60 kg N/fed., Meanwhile the highest Ca/P ratio was generally obtained from the pure berseem and the lowest Ca/P ratio obtained with the seeding rate of 20 kg berseem /fed. and 12 kg ryegrass /fed. and adding 60 kg N/fed., while the highest level of nitrate accumulation was generally obtained with the seeding rate of 20 kg berseem /fed. and 12kg ryegrass /fed. and adding 60 kg N/fed.
