The present study was aimed to verify the medicinal value of and traditionally used to treat human and animal ailments in Ethiopia. Fresh leaves of these species were collected, dried under shade, and ground into fine powder. The extraction was carried out by the maceration method using methanol as a solvent.

- Maize productivity has risen thanks to inorganic fertilizers, but their cost and environmental impact have made farmers wary, prompting this study to explore the use of cattle urine as a fertilizer alternative.
- The experiment compared different treatments: control, 100% cattle urine, 50% cattle urine, and standard inorganic fertilizer, and found that 100% cattle urine and inorganic fertilizers produced similar growth and grain yields.
- Results showed significant increases in grain yield and biomass with cattle urine treatments, particularly 100% and 50%, and 50% cattle urine had the highest nitrogen use efficiency, suggesting cattle urine could be a viable option for maize production, though more research is needed on its application rates.
Sesame ( L.) is an important cash crop cultivated under rain-fed conditions where it contributes a significant proportion of Ethiopia's foreign exchange earnings. However, its productivity is constrained by drought stress.

The study was carried out in the north-eastern highlands of Ethiopia to (1) analyze the effect of LULC changes between 1984 and 2021 and (2) assess the spatiotemporal variations in ecosystem service values (ESVs) and elasticity in response to LULC changes. Using Landsat imageries from 1984 to 2021, the spatiotemporal changes in LULC were evaluated with supervised image classification using maximum likelihood algorithm in ArcGIS software.
