Abstract

A study was conducted to evaluate the effect of tillage method and depth on furrow irrigation hydraulics and soil water storage during the dry season at Dire Dawa, Eastern Ethiopia. Treatments in the study included were chisel, moldboard and disk ploughing; and "Maresha" (local plough). Data obtained through field measurement and/or observations and laboratory analysis included soil data, irrigation water, advance and recession times, inflow-outflow volumes, available soil moisture, and infiltration rate at each irrigation event. Extending tillage depth significantly increased irrigation infiltration, increased irrigation water advance time, increased application efficiency, and increased saturated hydraulic conductivity; and significantly decreased tail water ratio and distribution uniformity in the first two irrigations, but had little effect during the successive irrigations.
