Abstract: The present study was conducted in experimental field of Department of Plant protection, Aligarh Muslim University, Aligarh to know the effect of different bio-control agents and fungicides on growth, biomass and yield of lentil crop. It is clear from the results that seed treatment with different bio-control agents (Trichoderma viride, Pseudomonas fluorescence and combination of T. viride + P. fluorescence) and fungicides (Carbendazim, Thiram, and combination of Carbendazim + Thiram) significantly enhanced the growth (plant shoot and root length), biomass (fresh and dry weight of shoot and root) and yield of crop (pod number, pod fresh weight and weight of 100 grain without and with shell). Among the different bio-control agents used, combination of T. viride + P. fluorescence proved best in enhancing growth i.e. plant height (47.66 cm shoot and 12.8 cm root), biomass i.e. fresh weight (shoot 15.66g and root 0.74g) and dry weight (shoot 2.41g and root 0.16g) and yield i.e. number of pods/plant was 30, pod fresh weight was 3.06g and weight of 100 grains with shell (10.7g) and without shell (7.03g). This was followed by Trichoderma viride and Pseudomonas fluorescence. This combination increased nodules number too. Among the fungicides used, Combination of Carbendazim + Thiram was proved best in increasing growth i.e. plant height (40.16 cm shoot and 8.83 cm root), biomass i.e. fresh weight (shoot 6.34g and root 0.37g) and dry weight (shoot 1.24g and root 0.07g) and yield i.e. number of pods/plant i.e. 24 and pod fresh weight i.e. 1.4g. This combination of fungicides also enhanced the weight of 100 grains and number of nodules. This was followed by Carbendazim and Thiram.
