Over 1995-1998 field experiments were carried out in the central-eastern Poland to define a Goat’s rue (Galega orientalis Lam.) yielding potential with and without Rhizobium infection. Over a single vegetation year two cuts were harvested and the dry matter yields (t·ha^-1) in respective experimental years from the non-infected and infected objects were as follows: in 1995 – 1.9-3.4; 1996 – 4.8-15.4; 1997 – 6.4-10.2; 1998 – 8.3- 11.8. The highest dry matter yield of 15.4 t·ha^-1 was recorded in the second Galega cultivation year with the Rhizobium infection. Considering the Goat’s rue dry matter yield and its calorific value of 17.8 MJ·kg^-1 of air-dried matter, the plant can constitute a source of energy.
