In 2013 a field experiment was carried out to figure out the effects of three different irrigation frequencies (twice a week, daily, several time a day) with manual or automatic irrigation systems on yield and fruit quality (fruit size, acidity, sugar, firmness) of strawberries cv. 'Clery' (Fragaria x ananassa Duch), as weel as on water use. The results showed that with frequent irrigation the amount of water could be reduced by 35 % compared to the treatment 'irrigation twice a week' without influencing yield and fruit quality. Consequences of the three irrigation treatment on the water content at different soil layers, as well as on economic outcomes are discussed.
