Radish and leaf vegetables contain a lot of vitamins and nutrients. Consumers increasingly think about a healthy and balanced diet. Experiments were carried out to clarify the effect of irrigation on the yield and the quality of lettuce, leaf mustard and radish. The experiments were arranged in high tunnels of the Pure Horticultural Research Centre during spring and autumn months of 2013. Leaf lettuce cv.‘Grand Rapids’; leaf mustard cv. ‘Scala’; and radish cv ‘Rudolf’ were grown in 3 replicas; the total area of each experimental plot was 1 square meter. The necessity of irrigation was determined by tensionmeters. The control variant had optimal soil moisture, the experimental plot had moisture deficit. The yield and its quality were determined at the end of the experiment. The results revealed the tendency that the higher yield of leaf vegetables was obtained at an optimal moisture variant. Radish was less sensitive to soil moisture deficit in comparison with lettuce and mustard. Irrigated vegetables had the tendency of having preference in organoleptic testing of vegetables. A higher content of chlorophylls was obtained at the optimal moisture variant.
