ABSTRACT:
Two
field experiments were conducted during two successive winter seasons of
2008/2009 and 2009/2010 to investigate the potentialities of mixing Egyptian
clover with ryegrass under bio, organic and mineral fertilization treatments
and their combination to increase forage yield and quality grown under sandy
soil conditions. The experiment included the combination of five mixing ratios
(Egyptian clover alone, ryegrass alone, 75% Egyptian clover: 25% ryegrass, 50%
Egyptian clover: 50% ryegrass and 25% Egyptian clover: 75% ryegrass) and eight
fertilizer sources, which include control,
organic fertilization, bio fertilization, chemical fertilizer, organic + bio
fertilizer, organic + chemical fertilizer, bio + chemical fertilizer
and combination of organic and chemical and bio fertilizers. The obtained
results indicate the superiority of 75% E. clover: 25% ryegrass mixture fertilizedby Bio + O + N in fresh and dry forage production. On
the other hand, it reported the lowest dry weight of weeds g/m2. Chemical
analysis of forage plants showed that the mixture of 75% E. clover: 25% ryegrass surpassed that of
other treatments yield for crude protein, ether extract and ash. The results
also revealed that the highest record of DCP, crude fiber and TDNY was obtained
by forage mixture of 75% E. clover: 25% ryegrass fertilized with Bio + O + N.
Such higher yield of these characters hassecured
a balanced ratio which is really needed for ruminants ration.
