Two field trials were carried out in winter season of 1999/2000 and
200012001 to study the variation en quality and quantity among different varieties and
accessions of berseem (Trifolium a/ex'!Jndrinum L.).For quantity aspect. a significant
differences in total green and dry yields (ton/fed).were found among varieties and
accessions at both the first season, the second season and the combined analysis
ov"r lhe two winter seasons .Serw-1 variety surpassed slgnifiantly (p. varieties and accessions in Dry yield(6.064 Uf). protein y\eld(1.037 Vf.), Total
digestible nutrient (TON) yield(3.673 t.lf.}. Digestible crude protein (OCP) yield(0.722
tit.) and Gross Energy (GE) yield (225.209 MJI1.). Accession(1) and
8~ssion(4)were the lowest in total Dry yield (4.861.1f. and 4.89 !.If.), crude protein
(CP) yieICf(O.814 t.1f. and 0.832 t.1f.), TON yield (2.95 t.1t. and 2.96 Uf.), DCP (0.564
1.If, and 0.583 t.1f.) and GE (176.738 MJIf. and176.208 MJ/f.). For quality aspect, Giza-6 and Sakha-4 varieties had the best quality over all
entries, Chemical constitunte showed that Sakha-4 was the highest in CP% (17.54%)
and 1he lowest Crude Fiber (CF%) (25.02%) which prove that it is the best variety
compared with other varieties and accessions. Accession(2)was the lowest in CP%
(1(;.72%) and the highest in CF% (26.49%). Total digestible nutrient (TDN) for Glza-6 (61.S2%), Sakha-4 (61.05%) were
the highest over all the other varieties and accessions. Accession(4) was the lowest
In TDN (59.91%), Sakha-4 was the highest in DCP (12.32%), while aocession(2) was
the lowest in DCP (11.57%) . However, Helalie variety was higher In GE (3.78 MJ)
than accession (5) (3.56) and accession (4) (3.S7 MJ) . For quality aspect, cell wall content revealed that Giza-6 variety was the lowest
in N!tutral detergent Fiber (NDF) (38.98%), Acid detergent Fiber (ADF) (25.86%) and
Acid detergent Lignin (ADL) (5.18%), Sakha-4 ranked the second with NOF (39.76%),
AOF (27.21%) and ADl (5.33%) while accession(4) recorded the lowest value in
quaPty with NDF (41.48%), AOF (30.38%)and ADL (6.03%).
