Résumé
An experiment was conducted in the highlands of Hararghe in eastern Ethiopia with the aim of characterizing the hydrophysical properties of the soil in the area and to determine the field water balance and water use efficiency of six haricot bean cultivars. Analyses of texture, bulk density, water retention curve and hydraulic conductivity for samples across the experimental site showed non-significant differences (p = 0.05) indicating uniformity in the conditions of the soil. Randomized complete block design RCBD with three replications was used. Data of the water balance were collected from two of the three replications for part of the crop growth cycle. Although the amounts of drainage and crop evapotranspiration obtained were significantly different (p = 0.05), the six varieties showed non-significant differences (p = 0.05) in their yield and water use efficiency.
