“…Compared with intensively cultivated land, the area planted with eucalyptus species can improve the physical and chemical properties of the soil by recycling nutrients through waste decomposition (Cuer et al, 2018; Liang et al, 2016; Mengistu et al, 2020). The soil nutrient status of the planting site is intermediate between degraded soil and native forest (Liang et al, 2016; Boulmane et al, 2017).…”

Plantation of Eucalyptus and Acacia species emerges as a promising alternative in the tropics in a scenario of high demand for provisional and regulating ecosystem services. The research aimed to characterize the spatiotemporal dynamics of ecosystem service values in response to planting practices of Eucalyptus and Acacia species in the Gilgel Abay watershed, Northwest Ethiopia. The threshold values of NDVI were employed to classify land-use/covers using cloud-free satellite imagery data in 1984, 1998, 2013, and 2021. The benefit transfer method of modified value coefficient was used to estimate ecosystem service values (ESVs) of the study watershed. Total ESV decreased from 1984 to 1998 due to the expansion of cultivated land at the expense of natural forests, shrubs, and grasslands. As food production increased, performance levels of climate regulation, erosion control, and nutrient cycle declined. In contrast, the service values of erosion control, climate regulation, and nutrient cycles were the major contributors to the overall increase in ESV from 1998 to 2021. This was caused by expanding Acacia and Eucalyptus species plantation at the expense of cultivated land in the watershed. The research revealed a trade-off relationship between provisional and other ecosystem services, such as regulating and supporting ecosystem service values in response to land-use system transformation. As a result, it is suggested that synergistic interactions between regulating, provisional, and supporting ecosystem service values be developed by merging plantation and cultivated land. Maintaining the right proportions of degraded plantations, protected natural forests, farmlands, and wetland ecosystems can be the most effective way to provide optimal multiple ecosystem services.

Moringa is a tree with medicinal, nutritional, industrial, and socio-economic values. Moringa leaf extracts have potential antihypertensive, antispasmodic, antiulcer, diuretic, hepato-protective and cholesterol-lowering activities. The study was conducted to analyze the nutritional quality of different moringa provenances and to promote the best provenances for the end users. Field experiments were conducted in Goro and Dallo Mena districts of Bale located in Oromia regional state of Ethiopia. Collected samples were air-dried at room temperature and milled for laboratory analysis. According to this study growing environment did not bring significant variation (P>0.05) in average mineral contents like Mg, Zn, P and CP content of the provenances. But significantly higher (P<0.05) Na, K, and Ca were recorded for the samples collected from Dallo Mena district, whereas higher Ash and Fe content was recorded in Goro district. On the other hand, provenance from Dallo Mena and Bako is superior to most of the quality characters analyzed. However, the one from Arbaminch is higher in Na and Zn contents. Provenance from Abay Filiklik is higher in Ash, K and P content. Moringa leaf is rich in Ash, Zn, Cp, and Mg to the sufficient level, while Fe, Ca and P are to the level of high or double to triple to the optimum level when compared to the optimum nutrient content of plant material. Generally, higher mean and individual chemical quality values were recorded from provenances grown in Dallo Mena district except for K, Fe, Zn, and CP, which are higher in Goro. Int. J. Agril. Res.

“…With compare to other tree species farmers give high priority to Eucalyptus tree species especially for poles, farm implementation, construction and fences [25]. Eucalyptus is properly planted with its recommended space and well managed; it can supports and improves and produce highly biomass or yield and soil nutrients status [17,19]. Since most farmers plant Eucalyptus globules for fuel wood production therefore, Yield is very important parameter that used to Eucalyptus globulus plantation [22].…”

This study was conducted in the Eucalyptus globulus tree growing area of Wogera district, North Gondar, Ethiopia. The results showed that there was a significant difference in the mean yield/volume of Eucalyptus globulus, ranging from 78.9 ± 51.3 m3 ha-1 (mean ± SD) to 148.6 ± 54.7 m3 ha-1. Coppicing levels, interaction of season and coppicing levels were statistically significant at p < 0.001 and p < 0.05, respectively. We also found that there was a significant difference in the mean basal area of Eucalyptus globulus, ranging from 15.5 ± 7.7 m2 ha-1 (mean ± SD) to 21.3 ± 6.7 m2 ha-1. Coppicing levels, interaction of season and coppicing levels were statistically significant at p < 0.009 and p < 0.006, respectively. The number of trees per hectare varied from 10682 to 15135 trees ha-1. First coppicing had the highest number of trees per hectare with 18400 trees ha-1, followed by second coppicing level 15135 trees ha-1 and third coppicing level 11546 trees ha-1. The number of trees trend showed a decreasing pattern with increasing the level of coppicing. The lowest numbers of trees were found in not coppiced trees. The mean diameter varied from 3.5 ± 0.3 (mean ± SD) to 4.1 ± 0.5 with the first coppicing level and third coppicing levels, respectively. The results indicated that the mean number of re-sprouts/shoots of the study area varied with different coppicing levels. The number of re-sprouts/shoots increased with the increasing of coppicing level. The highest and the lowest number of sprouts/shoots were Mean 309 ± 87.5 trees ha-1 and 223 ± 28.1 in third and the first coppicing levels, respectively.
