Cattle production in humid lowland tropics has been criticised for its extensive management. Dual-purpose cattle production system has been preferred by small and medium sized farms in such regions due to low capital and technical demands with low risk for fanners. In order to quantify the effects on production of silvopastoral areas in the dual-purpose cattle production system, relations between land use patterns and seasonal production and herd data were examined for 7 4 farms in semi-humid regions of central Nicaragua. The results showed that grazing lands were largely covered by tree cover (23 % on average), and land use were largely composed of degraded pastures (32%) and pasture with low and moderate tree densities (45%). The results of regression analysis demonstrated the positive effects of degraded pastures (DGPS) (p<0.001), natural and cultivated pastures with moderate tree density (MTNP and MTCP) (p<0.05), and cultivated pastures with low tree density (LTCP) (p<0.05) on milk production. However, the negative effects of land use types under natural pasture with low tree density on milk production (LTNP) (p<0.01) was also observed, which may suggest overgrazing with higher stocking rates (p<0.01) on this land use type by smaller farms. The results of herd survey showed that although cattle were frequently moved from and to the fanns, stocking rates did not differ by season (p<0.05), and that calving rates were significantly high in the dry season (p<0.05), resulting in significantly low milk production per cow (p<0.05) and tendency to have high adult mortality rates. The study concluded that silvopastoral areas are largely utilized for cattle production with positive effects on milk production. Further studies are recommended on stocking rates and change of sward composition, feasibility study on pasture improvement with use of fertilization and/or silvopastoral techniques, and availability and nutritional values of broadleaved plants in dry season.
