Combination of Rhizobium and Trichoderma species were studied to document their compatibility their synergism, antagonism under in vitro condition and their effects on the growth of lentil in vivo condition. In respect this, few strains of Trichoderma were isolated from the rhizosphere soil of Pulse crop from different locations of West Bengal and they were tested in vitro and in vivo along with Rhizobium to know the interaction between them and the growth behaviour on lentil. The results indicated that Rhizobium and Trichoderma isolates showed compatibility in between them in their growth. The cultural filtrate of different isolates of Trichoderma were also used to find out the antagonistic potentiality or compatibility against Rhizobium and found that some strains showed compatibility for their growth and some cause inhibition on the growth of Rhizobium. The pot culture experiment was done through seed treatment of different Trichoderma isolates and Rhizobium individually and in combination, showed differential growth characteristics of Lentil. The numbers of root nodules, weight of fresh and dry nodule were significantly increased when Trichoderma isolate of Shekhampur and Market sample were mixed with Rhizobium in comparison to sole application of these two organisms. Whereas, shoot length, fresh shoot weight, root length and dry root weight were increased though their differences were statistically insignificant. The result therefore suggested that combined application of native Trichoderma isolate and Rhizobium can increase the growth and total biomass of lentil which play an important role in organic agriculture.
