Evaluation of Coffee Genotype for Drought Tolerance and Water Use Efficiency in Western Ethiopia at West Wollega

The growth and output of coffee are significantly hampered by drought. To lessen the effects of climate change on coffee production, it is crucial to choose genotypes of Arabica coffee that are resistant to drought. The goal of the study was to select genotypes of Wellega coffee that are drought-tolerant at the Haru Agricultural Research Sub-Center in the Oromia National Regional State, Western Ethiopia. The experiment was carried out in a controlled environment from 2017 to 2019 G. C., with three replications laid out in RCBD. For 28 days, two watering regimes—well-watered and water-stressed—were applied to fourteen genotypes of Wellega coffee. The mother trees of genotype were tested at field condition. The experiment's findings showed that the genotypes not differed significantly in terms of total dry matter, relative leaf water content, and leaf retention capacity as well as in terms of the degree of wilting and in all destructive parameters. So, to select the drought tolerance coffee genotypes the stress period should be minimized in to 15-21 days.
