Laboratory, pot and field experiments were carried out at the Vezaiciai Branch over the period 1995-1997. We investigated the efficiency and physiological properties of different strains of Rhisobium galegae. The occurence of these of these bacteria is very poor and uneven in the soils of Lithuania. Reguliarities between soil properties and Rhisobium galegae occurence were determined. Inoculation of the goat's-rue (Galega orientalis), cv. 'Gale' with local and imported R. galegae strains showed a high efficiency. Dry matter yield increase made up from 1.06 to 1.50 t/ha. Some strains increased the content of crude protein in the plant yield by on average 1.03-1.14 or 177-283 kg/ha. Our findings did not confirm the significance of R. galegae strains ecological adaptation for their symbiotic efficiency. Nitrogen fertilization (N90) did not produce any positive effect on both not inoculated and inoculated goat's rue
