Use of indigenous forage species,
such as Eleusine indica could be
one of the alternatives to solve the problem of scarcity of feeding
materials in
Nepal.
Re-growth potentials of Eleusine
indica was studied in dry season at
Rampur, Chitwan during December 2002 to May 2003.
Split
plot design was used for the field trial. Different rates of nitrogen
fertilizer (0 kg ha-1, 50 kg ha-1, and 100 kg ha-1)
were the main plot treatments, while the sub plots were different
defoliation regimes (2, 4, and 6 cm cutting height above the ground).
Re-growth estimation of fresh biomass was carried out. Similarly, chemical
constituents of the Eleusine indica
were also analyzed. The study revealed that nitrogen fertilizer
application (100 kg ha-1) resulted in increased re-growth yield
of Eleusine indica. The
cumulative re-growth of four harvests during January 2002 to May 2003 was
10.9 mt fresh biomass ha-1 with the use of 100 kg N ha-1
fertilizer and harvested at 2 cm defoliation height. However, defoliation
height had no significant effect on plant re-growth (P>0.05). This indicated
that Eleusine indica could be
defoliated / grazed as low as up to 2 cm height from the ground without
hampering its persistency. On the other hand, the CP content of
E. indica was 12.37 % during
winter. CP content was comparatively higher with the increased in nitrogen
fertilizer application (P<0.05). The findings revealed that there is very
good potentiality of E. indica as
a native forage species, particularly during dry season, to fulfill the dry
matter shortage.
