| Abstract | ||
| Studies on the effect of K fertilizers application in increasing water use efficiency and decreasing the negative effect of water stress, quite limited especially under field conditions. A field experiment was conducted in silty clay loam in Agricultural Research Station of Abu-Graib- Baghdad, Iraq to study the effect of different 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 irrigation (after depletion of 50 and 75 % of available water). Results revealed the following | ||
