In Ethiopia, peanut is a food, feed and cash crop. The national mean yield is 1.75 tons/ ha, and the total area under peanut production is 81,848 ha (FAOSTAT, 2019). Babile and Fedis districts, in the Eastern region of Ethiopia are popular for peanut production. Recurrent drought is one of the major production constraints in the region. The water-deficit stress pattern (duration, time and extent) at Babile and Fedis districts was determined using the 31-years historical graded weather data of target environments of Ethiopia. Based on this the planting window at Patancheru and water deficit stress were decided to mimic pattern of the target environments using lysimeters.
