A field experiment was  carried out at Gemmeiza Research station during the two successive seasons; 2005 and 2006 to evaluate ten maize hybrids for silage yield, quality, and nutrient contents. The experiment included three single cross (SC10, SC123, SC155) and seven three-way cross hybrids TWC310, TWC311 TWC320 TWC321, TWC322, TWC323,and TWC324 . Significant differences (P0.05) were found among the tested hybrids; The highest fresh silage yield was recorded for hybrid SC10 in both seasons, (23.94 and 25.31 tons / faddan, respectively). Hybrids TWC320 and TWC324 possessed the highest dry matter (DM) yield in the two seasons (6.65 and 7.51 t fad^-1), respectively. It was evident that the number of days to 50% tasseling, combined  over the two seasons, ranged between 59 and 66 for SC155 and SC123 hybrids  respectively . Respecting to 50% sillking, the combined analysis showed 8.25 days difference between the earliest ( SC155) and the lastest hybrid (SC10). Results at silage maturity stage, which was assessed on the DM basis ranged between 283 (SC123) and 340 (TWC324) g Kg^-1 . Data showed that crude protein % ranged between 5.9% (TWC323) to 8.2% (TWC310), CF between 22.4 (TWC320) to 29.5 (TWC), EE between 1.32 (TWC310) to 2.97 (SC10), NFE between 55.1 (TWC324) to 60.1 (TWC320), Ash between 6.3 (TWC322) to 8.5 (TWC311), DCP between 2.03 (TWC323) to 4.15 (TWC310), and TDN between 62.1 (TWC323) to 63.9 (TWC311). For silage quality, pH ranged from 3.6 (TWC311) to 4.05 (SC155), VFAs from 1.46 (TWC311) to 2.44 (SC155), Lactic acid from 3.78 (SC155) to 5.25 (SC10), and NH₃N % from 4.08 (SC123) to 6.88 (SC155). These data indicate that all hybrids are suitable for silage production.
