520 _aStudies on the effect of K fertilizers application in increasing water use efficiency (WUE) and decreasing ihe negative effect of water stress,are quite limited. especially under field conditions. A field experiment was conducted in silty clay loam in the Agricultural Research Station ofAbuGraib- Baghdad. Iraq to study the effect ofdifferent levels of K fertilizers application on potato (Solanum tuberosum L.) and their role in decreasing negative effect of water stress. Treatments include four levels of K fertilizer (0, 200, 400 and 600 kg K₂SO₄ ha⁻¹ ) and two levels of irrigation (after depletion of50 and 75 % of available water). Results revealed the following:- 1. The negative effects of water stress on potato growth and yield decreased by increased application of K fertilizers. 2. Negative effects of water stress on plant quality and WUE were decreased by increasing level of K fertilizer in depletion 75% of available water. and saving in irrigation water with irrigation scheduling by 9%.
