Effect of liming and pre-sowing seed inoculation of alfalfa and red clover dry matter yield and quality were studied during three year period. The seed of alfalfa (NS Mediana ZMS V and NS-Slavia) was inoculated with two pH resistant Rhizobium melliloti (R1, R2) strains, and that of red clover (the Kolubara cultivar) with one Rhizobium leguminosarum bv. trifolii (R) strain. The pre-sowing inoculation gave rise to a significant increase in dry matter yield of alfalfa and red clover in all three study years. This pointed to the stability of the Rhizobia used in the soils with a low pH value, which justified selection of these strains and their use in establishing crops of these species. The significant increase in dry matter yield in the treatments with CaO in the first year in both species provided a justification for using these measures on acid soils. However, in the second and third years, the rate applied did not bring about any significant yield increase indicating the need for standardization of lime material rates and its deeper inoculation, given the root traits of these species.
