Seed yield of lentil (Lens culinaris Medik.) was investigated in relation to Rhizobium leguminosarum inoculation under dry and irrigated conditions during 1988-93 seasons in Erzurum, Turkey. Under dry conditions, seed yield of cv. Kislik Kirmizi-51 after inoculation, 20 kg N/ha application and inoculation + 20 kg N/ha was increased by 6, 12 and 4, respectively, compared with the control. Application of P2O5 up to 80 kg/ha increased yield by only 4, but the combination of 20 kg N/ha with 80 kg P2O5/ha increased yield by 16 compared with the control. Inoculation + 20 kg N/ha produced the highest protein content. P application enhanced this effect. Under irrigated conditions, among eight pre-selected R. leguminosarum strains, F15 produced higher seed yields and strains M90, M9, M11 and M13 gave higher protein content in cv. Erzurum-89 than the control in the presence of indigenous bacteria. In conclusion, because of the presence of indigenous bacteria, Rhizobium inoculation may not necessarily give higher yields unless effective local strains are used
