The role of biological fertilizers is important in improvement of soil physical and chemical properties.This project was carried out as factorial in randomized complete block design with four replicates during 2006-2007 at Khomein national bean research station.Factor (A) included five different rhizobium strains(L-216, L-120 ,L-39, L-58 and L-109),with nitrogen fertilizer(100 kg N ha-1) and control(without inoculation and fertilizer) and Factor (B) included three red bean varieties(Akhtar , Goli and D81083 line).The analysis of variance showed that rhizobium treatments were significantly effective on plant height and pod per plant, varieties were significantly effective on number of days to maturity, number of days to flowering, plant height,100 grains weight,pod per plant, grains per pod, grains per plant,grain yield and N concentration.Interaction between rhizobium strains and varieties were significantly effective on pod per plant and green area percentage.The maximum yield obtained from L-120 rhizobium strain(2950 kg ha-1),but there was no significant difference between treatments. The maximum grain yield were obtained from interaction between L-39 rhizobium strain and Goli variety (3190 kg ha- 1),L-120 rhizobium strain and Akhtar variety (2692 kg ha-1) and L-58 rhizobium strain and D81083 line(2678 kg ha-1).
