During the period of 2000 and 2001, field trials were established with the aim to evaluate the productivity and forage quality of lucerne. The most productive lucerne varieties were 'Birute', 'Radius' and 'Belorusskaya' yielding 13.5-14.6 t ha*[-1) DM, during the years of sward use. The most content of crude protein 170-175 g kg*[-1) have been obtains from 'Karly', 'Radius' and 'ABT-205'. The highest digestibility was observed in the developing line No 60. Acclimatization of rhizobia within lucerne roots has been determined applying streptomycin resistant forms. In field conditions acclimatization within lucerne was more successful by strains 05 (40-100%).
