The article gives a brief review of literature on the importance of Galega orientalis in fodder production and the
results of research on irrigation regimes in other countries. The results of own research on irrigation regimes of Galega orientalis on sod-podzolic soils in the north-eastern part of Belarus are pre-sented. It is established that the maximum biological potential of Galega orientalis is revealed at the regulation of the soil moisture content in the range of 70–100 %. It is possible to keep soil moisture reserves in the range of 70–100 % only applying the following irrigation norms: in a very dry year (P = 5 %) – 90–113 mm; in an average year (P = 50 %) – 32–37 mm; in a humid year (P = 90 %) no irrigation required.
