Miah M.G. Aragon M.L. Garrity D.P. 1997. Growth biomass production and distribution of three multipurpose tree species in an agroforestry system as affected by prunning. This paper presents the results of an experiment to assess the growth biomass production and distribution pattern of three multipurpose tree species (Acacia mangium A. auriculiformis and Gliricidia sepium) grown alone and in association with rice and mungbean under pruned and unpruned conditions. The experiment was laid out in July 1990 and concluded in August 1992. The two-year comparative study of tree species showed that Acacia mangium attained the highest height (7.6 m) diameter (12.1 cm) and stem dry biomass (17 141 kg per ha) while A. culiformis produced the highest leaf (12 465 kg per ha) branch (16 368 kg per ha) and total biomass (43 935 kg per ha) among the unpruned treatments. Intercropping annual crops with the trees had no significant effects on the performance of any of the tree species but tree branch pruning had a significantly negative in all the tree parameters studied. The total biomass in pruned trees was 27 - 39 percent lower than that in unpruned trees at the age of two years. Tree species differed substantially in biomass distribution pattern among their constituent parts which might be due mainly to species differences.

Abstract

Miah M.G. Aragon M.L. Garrity D.P. 1997. Growth biomass production and distribution of three multipurpose tree species in an agroforestry system as affected by prunning. This paper presents the results of an experiment to assess the growth biomass production and distribution pattern of three multipurpose tree species (Acacia mangium A. auriculiformis and Gliricidia sepium) grown alone and in association with rice and mungbean under pruned and unpruned conditions. The experiment was laid out in July 1990 and concluded in August 1992. The two-year comparative study of tree species showed that Acacia mangium attained the highest height (7.6 m) diameter (12.1 cm) and stem dry biomass (17 141 kg per ha) while A. culiformis produced the highest leaf (12 465 kg per ha) branch (16 368 kg per ha) and total biomass (43 935 kg per ha) among the unpruned treatments. Intercropping annual crops with the trees had no significant effects on the performance of any of the tree species but tree branch pruning had a significantly negative in all the tree parameters studied. The total biomass in pruned trees was 27 - 39 percent lower than that in unpruned trees at the age of two years. Tree species differed substantially in biomass distribution pattern among their constituent parts which might be due mainly to species differences.
