Abstract
Two field experiments were carried out at the Experimental Farm, Sers- Elliyan Agricultural Research Station, Menoufia Governorate, during two successive seasons (1998/99 and 1999/2000) to study growth characters, fresh and dry forage yield and its components of ryegrass as influenced by different forms and time of nitrogen fertilizer application. The results could be summarized as follows:
Ammonium sulphate was more efficient in enhancing plant height, number of tillers/plant, leaf area/plant, stem diameter, fresh and dry forage yield, crude protein, crude fiber and ash yield of ryegrass than urea. The application of nitrogen fertilizer as four splits, '14 three weeks after sowing + ';' before the 2nd, 3'd and 4th cuts significantly increased growth characters, fresh and dry forage yield and forage quality [crude protein, crude fiber and ash yields 1 of ryegrass.
The interaction between nitrogen forms and time of nitrogen application had insignificant effect on growth characters (plant height, number of tillers/ plant, leaf area/plant, and stem diameter), fresh and dry forage yield, except the fresh yield at the 1 st cut of the 1 st season and dry forage yield at the 2nd cut of the first season and at 1 st cut of 2nd season were significant. Also, forage quality (crude protein, crude fiber and ash yield) was insignificant in both season.
