| Abstract | Planting of forage after rice was tested in a small-scale
integrated farm on acid sulphate soils to determine the
possibility of improving feed supply in the dry season using
residual moisture and fertility after rice cultivation. Four
forage legume species, Mungbean (Vigna radiata), Lablab (Lablab
purpureus), Verano stylo CStylosanthes hamata) and Graham stylo
CStylosanthe sguianensis), were grown under four methods of
establishment; broadcasting before rice harvest, broadcasting at
rice harvest, broadcasting at rice harvest + harrow and furrow
and drilling. Five - month qualitative observations were also ma de
on nine forage legume species to determine the potential of these
species for forage production under the farm condition.
Only Verano and Graham stylo survived through the dry season
but they did not produce substantial dry matter until the early
wet season. Verano stylo being fast growing produced 340% more
dry matter than Graham stylo during the seven-month experimental
period. The increase in dry matter production was however not
significant to the farm since native forages in the fallow field
were already abundant during the period. Nevertheless a
significant increase of about 76% in crude protein content of the
feed was achieved. Producing crude protein from Verano style is
cheaper than buying supplementary feeds such as soybean or fi s h
meal. Although crude protein from urea is cheaper than Verano
stylo, it may not be appropriate for a small - scale farm. The
method of establishment did not affect the dry matter production
of the forages but did affect the initial plant population.
Other forage species which showed appreciable growth during
the dry condition and early wet season were Centrosema, Siratro
and Calopo. |
