Even though Ethiopia is one of the most endowed countries in having huge coverage of bamboo resource in Africa, the country has narrow genetic diversity only has two species; Yushania alpine (highland bamboo) and Oxytenanthera abyssinica (lowland bamboo). The adaptation of lowland bamboo was conducted at Haro Sabu Agriculture Research Center from 2016 to 2019 to evaluate the adaptability potential of different performance of lowland bamboo species and to identify the best performing of lowland bamboo species around Haro Sabu areas. Based on the objectives, four different lowland bamboo species were collected from Bako Agriculture Research Center. The species are: Oxythenantera abyssinica, Guadua amplexofolia, Dendrocalamus hamlitonii and Dendrocalamus memebranceous among those mentioned only Oxytenanthera abyssinica are indigenous the rest are exotics. The experiment was laid out in RCBD with three replications. The selected bamboo species has good survival and adaptability at Haro Sabu area except some growth variation. Despite this fact, Dendrocalamus asper species is show high difference in new emerging shoots, internodes length, culm height and culm diameter whereas, Oxythenantera abyssinica revealed low in all growth parameters. So, based on these results we recommend Dendrocalamusasper, Dendrocalamus hamlitonii and Dendrocalamus memebranceous for different production since they have a good internodes length, ability to emerge new shoots, culm height and diameter while the growth of Oxythenantera abyssinica is quite different when compare with others. Therefore, the adaptation of lowland bamboo under Haro Sabu and related agro ecologies is reliable so, we recommend for further economic and livelihood benefits for different stakeholders through expanding the plantation.

The objective of this study was to evaluate the growth performance of some selected multipurpose tree species at termite affected area. A termite-affected area of 128m x 48m was purposefully chosen for this study, and seedlings of G. robusta, C. macrostachyus, J. mimosifolia, M. azedarach, and O. africana were randomly assigned to an area and out planted on a 20m*40m treatment plot. The space between plots of each species was 4m and, 2m Spacing between rows and within row was used for each species. In each treatment plot, B. humidicola grass was sown with no tillage. On the space between plots, a physical soil and water conservation structure (soil bund) was built. In order to fit the given objectives the tag was given with its corresponding numerical code to seedlings within plots of each tree species and; data on height, root collar diameter, survival percentage was collected on 11.1, 23.4, 34.6 and 45.3 months from each tree within plots except the border. Data on tree survival percentages were separately subjected to ANOVA and Tukey's HSD tests were used to examine the results at p=0.05 to discover differences among tree species in their survivals. The relative growth rate in height of tree species was plotted using data collected on seedling height (RGR). The results showed that the overall survival rate of the tree species was high, ranging from 65.97 percent (C. macrostachyus) to 76.03 percent (G. robusta) at a given location. G. robusta and J. mimosifolia, on the other hand, grew faster in height than the other species.

The objective of this study were to evaluate adaptability and growth performance of different multipurpose tree species and to select or screen those best performed and adapted to the area. Seedlings were out planted on a plot of 12mx12m for each species, spacing between row and within row were based on recommendation of each species. In order to fit the given objectives data were collected on the following parameters:- Date of sowing, date of emergence, date of planting, growth parameters: diameter (RCD and DBH), height and survival rate were recorded and measured. Diameter(RCD and DBH),height and survival rate were collected by an interval of 3 months.As a result, Height growth response were shown significance difference (p<0.000) for Grevillea robusta , Casuarina equisetifolia and M. stenopetala .

Similarly, the growth response in root collar diameter data also reviled that there were highly significant differences (p<0.000) among the species. High mean value of root collar diameter was recorded for Grevillea robusta ,Casuarina equisetifolia while it was low in Cordia africana and Mellitia ferrugenia respectively. The basal area of the species shows high mean value on Grevillea robusta followed by Casuarina equisetifolia while had low mean value on Cordia africana.The survival result also showed, Moringa stenopetala were higher (84.72%) followed by Grevillea robusta (81.81%), Casuarina equisetifolia (73.86%) ,and Mellitia ferrugenia (73.33%), while survival of Cordia africana were the lowest(40%). Thus, poor survival and growth response were observed on Cordia africana that might be explained as a response to the specific site condition of the study area. Generally, these findings may help forest managers (stakeholder)to properly allocate species into the site that grow and adapt well. Further testing of provenances of the best performing species is recommended to select the most adaptable ones for such areas for future forest plantation establishment at wider scale; on which success of forest plantations depend.

The objective of this study was to evaluate the adaptability and growth performance of different multipurpose trees/shrubs species and select or screen those best performed and adapted to the area. For this seedling of: Acacia senegal, Pinus patula, Callistemon citrinus, Olea africana and Spathodea nilotica were out planted on a plot of 14m*14m. The space between block of each species was 3m and Spacing between rows and within row was based on the recommendations of each species. In order to fit the given objectives growth parameter data of trees/shrubs (height, root collar diameter (only for trees< 1.3m in height), diameter at breast height (for trees ≥1.3m height) and survival rate) were collected by an interval of 6 months and Analyses of variance and LSD tests were employed to assess the results at p=0.05 using Minitab 17. As a result, the higher mean height growth was observed on Callistemon citrinus (2.59 m), Spathoda nilotica (2.48 m) and Pinus patula (2.34 m). Again Gains in root collar diameter (RCD) was significantly highest on Pinus patula (37.75cm, 2.81cm) and Spathodea nilotica (32.08cm, 3.52cm).The Mean survivals of all trees grown at site were good ranging from 85.36% (Pinus patula) to 100% (Spathodea nilotica (100%). Generally this finding may help forest managers (stakeholder) to allocate species into the site that grow and adapt well. To select the most adaptable ones for such areas , use them at wider scale and increase their importance in the overall agricultural productivity (soil conservation, timber production, shading purpose, etc) and in general multifunction purposes in the area, further testing of provenances of the best performing species is recommended.
