Two field experiments were conducted at the Experimental Station, Faculty of Agriculture, Mansoura University during the two successive seasons of 2000/2001 and 2001/2002. A split-plot design in four replications was used. This investigation aimed to study the effect of seeding rates and cutting schedules parameters on chemical dry matter analysis of Egyptian clover variety Miskawi Giza 6. Crude protein and fiber, ash content, ether extract and nitrogen free-extract percentages in blades and stems and its yields/fed were significantly affected due to cuttings. Highest percentages of CP and ash in blades and stems were produced from the second cut. While highest percentages of CF and EE in blades and stems were produced from the third cut. The fifth cut achieved the highest percentages of NFE in both blades and stems. Moreover, highest crude protein and ash yields per feddan were produced at the second cut. The third cut produced highest averages of CF, EE and NFE yields per feddan. Seeding rates caused significant differences on Crude protein (CP), Crude fiber (CF), ash content, EE and NFE percentages in blades and stems and its yields/fed were significantly affected due to seeding rates. Highest percentages of CP and EE in stems were resulted from sown with 30 kg seed/fed. While, using 45 kg seed/fed was accompanied with the highest percentages of CF and ash content in both blades and stems as well as NFE % in blades only. Moreover, the highest yields of CP, CF, ash, EE and NFE yields per feddan were produced from the medium seeding rate of 30 kg seed/fed. Percentages of CP, CF, ash content, EE and NFE in blades and stems as well as CP, CF, ash content, EE and NFE yields/fed significantly responded as a result of cutting schedules under study. Highest CP % produced from cutting plants at 30 cm height and after 25 days intervals in both blades and stems, respectively. While, highest percentages of CF, ash content and EE in both blades and stems were produced from cutting at 50 cm height. Cutting Egyptian clover plants at 55 days intervals produced highest NFE %. Moreover, highest of CP, CF, ash content, EE and NFE yields/fed were produced from cutting at 30 cm height. There was non significant interactions between seeding rates and cutting schedules treatments on chemical dry matter analysis, this mean that each factor acted separately. It could be summarized that for maximizing forage quality of Egyptian clover Giza 6 cultivar with sowing at seeding rate of 30 kg seed/fed and cutting plants at 30 cm height under the environmental conditions of Dakahlia Governorate.
