Zusammenfassung:The purpose of this study was to analyze the trend and variability of rainfall and temperature parameters in the teff growing belts of Ethiopia. The data were obtained from weather stations and covered 1981–2018. Data analyses were carried out with descriptive statistics and time trend regression model. The results showed that short-season rainfall declined by 0.474 mm, while long-season rainfall increased by 2.72 mm.
