| Abstract | Two experiments were conducted over a period of eight months
in order to find a solution to t he problem of scarcity of feed
for t he buffalo component in the livestock sub - system at the
Crop/ Livestock / Fish Integra ted Farming System in Asian
Institute of Technology , Bangkok , Thailand .
The first experiment studied t h e effect of five rates of
Phosphorous fertilizer (Triple Super Phosphate ) namely 0,20,40,
60 & 80 Kg P/Ha on t h e establishment of Guinea / Style (Panicum
maximum I Stylosanthus hamata cv.verano ) mixed s ward in order to
provide feed during the times of scarcity , the dry and the early
wet season.
The second experiment studied the effect of two sources of
Nitrogen fertilizers, Urea and Calcium Ammonium Nitrate under
five rates of N namely 0, 100, 200, 300 , 400 Kg N/Ha in order to
supply the wet season feed from existing Paragrass (Brachiaria
mutica ) .
Phosphorous (P ) fertilizer increase d the Dry Matter Yield (
DMY) and Phosphorous concentration in Guinea grass but it was
still inadequate to meet the demand of the buffalo
component, during the dry and the early wet season. 40 kg PIha
was found as the optimal level of P for grass/legume mixed
pasture. When grown with grass the legume content was only 6%
at the optimal l e v e l of P application.
Application of Nitrogen to Paragrass significantly increase
t h e dry matter yield b u t variability of rainfall during the
experimental period led to fluctuations in the yield. Of the two
sources tested CAN showed better Nitrogen recovery than Urea upto
300 Kg N/ha . But the yield differences were not of, significant
proportions.
It was concluded that by fertilizing the 0 .58 ha of
Paragrass with Nitrogen and growing the grass/ legume mixed
pasture with Phosphorous in the one hectare of rice area during
off season that it is possible to meet the dry matter requirement
and Digestible Crude Protein requirement of the buffaloes during
the early wet season, together with other crop residues available
in the farm.
