Morphological Characteristics and Growth Performance of Bambusa vulgaris Schrad. Ex J. C. Wendl in Selected Agro-Ecologies of Uganda

Abstract

Bamboo is a versatile and valuable resource that has been shown to have social, ecological, and economic benefits in many countries worldwide. Even though Uganda has a suitable environment for bamboo growth, it remains underutilized. One of the key challenges in promoting bamboo farming is the need for more information about the growth performance of different bamboo species in various site conditions. Therefore, this study determined the morphological characteristics and growth performance of Bambusa vulgaris in Uganda. A total of 24 bamboo farms were selected from a list of bamboo farmers provided by key informants using stratified sampling. These farms had relatively uniform B. vulgaris stands and were drawn from Uganda's three agro-ecological zones (AEZs): the Southwestern, West Nile, and Lake Victoria crescent agro-ecological zones. Eight temporary sample plots were established in each zone, and various growth parameters were measured. One-way Analysis of Variance (ANOVA) followed by Sidak post-hoc test was used to compare the performance of B. vulgaris across the different agro- ecological zones based on growth parameters. The results of the study showed that the total above-ground biomass was highest in the Lake Victoria crescent (24.773 kg/ha), followed by the West Nile (17.141 kg/ha) and the Southwestern (15.125 kg/ha) agro-ecological zones. The growth rate of B. vulgaris after three years was found to be similar to the outstanding growth rate mentioned in the literature. The growth performance of B. vulgaris was notably better in the L. Victoria crescent compared to the West Nile and Southwestern highlands – suggesting that efforts to promote the growing of B. vulgaris should prioritize the L. Victoria crescent agro-ecological zone. Overall, this study provides valuable information on the growth performance of B. vulgaris in different agro-ecological zones in Uganda. This information can be used to guide the promotion and development of bamboo farming in the country, which has the potential to improve livelihoods and contribute to sustainable development.
