Abstract: | Effects of pruning on biomass growth in Prosopis juliflora were examined under dryland conditions in the Sudan. Growth parameters were followed for a total period of 32 months and water content, and gas exchange measurements were carried out. Heavily pruned trees yielded more than six times larger usable wood volume and produced 60% more leaf biomass than the control. The water status in pruned trees was improved which also had a more efficient CO2 assimilation rate, associated with higher stomatal conductance. The results and their implications for the management of sparsely spaced P. juliflora are discussed in relation to agroforestry. |
