Analysis of study results revealed that the highest water level was recorded at the end of March, the lowest – in the middle of June. In the analyze study result, the depth level of water in points 1 – 5 standard exceedance drainage. Negative water relations affected the hay yield that was from 25 up to 60 dt.ha-1.
