<jats:title>Abstract</jats:title><jats:p>Effects of exogenous applied lipids being of microbial origin on the water use efficiency (WUE) and the biomass production have been studied in pot and field experiments using crop plants.</jats:p><jats:p>Lipid mixtures extracted from the cells of <jats:italic>Candida maltosa</jats:italic> EH 15 increased the WUE (9…16%) and the grain yield (÷x = 10%) of the wheat and barley plants under dry conditions. The fatty acid fraction separated from the lipid mixtures also improved the WUE especially under stress (20…100%) and the biomass production. The phosphatide fraction emulsified with sulfonate containing solvents was not physiologically active.</jats:p>
