E.C. and pH of irrigation water was fluctuating much (Fig. 6). The E.C. of applied water ranged most of the time between 1,2-2,0 and the pH between 4,0-7,0. The E.C. of runoff stayed most of the time between 0,8-2,4 and the pH between 5,5-8,5.

At the beginning of the growing period was the irrigation adjusted to no runoff due to the rooting down of the roots. After that was the amount of runoff increased. The amount of runoff from applied irrigation fluctuated very much and varied most of the time between 10-50 % runoff. In average had Sonata a higher runoff than Magnum (Fig. 7).
