The production and harvest areas of tomatoes in West Kalimantan tend to decrease. One of the cultivation techniques that is expected to increase the yield and quality of the plant is by using organic fertilizers. The study objective was to determine the effects of interactions between cellulolytic fungi and biofertilizer doses on the growth and yield of tomato (Solanum lycopersicum L.) in alluvial soils. A completely randomized design (CRD) with factorial patterns was applied in the research. The first factor which was cellulolytic fungi in biofertilizers (J) included: J0 (organic fertilizer without decomposer), J1 (organic fertilizer with Aspergillus sp.), J2 (organic fertilizer with Trichoderma spp.), and J3 (organic fertilizer with Aspergillus sp. and Trichoderma spp.). The second factor that was of biofertilizer doses (D) consisted of: D1 (25 g / polybag), D2 (50 g / polybag), D3 (75 g / polybag), and D4 (100 g / polybag). The results showed no significant difference between the cellulolytic fungi and biofertilizer doses on all observation variables (p > 0.05). There was no significant main effect of cellulolytic fungus type on all observation variables, while the treatment of biofertilizer doses had a significant effect on plant height, total leaf number per plant, fruit number per plant, and fruit weight per plant. The J3D4 treatment gave the best results on the plant height (97.67 cm) and the leaf number (18.17 strands), while the J2D4 treatment gave the best results on the fruit number per plant (3.31 fruits), and the fruit weight per plant (13.32 g). The addition of cellulolytic fungi to biofertilizers at a dose of 100 g / polybag can increase growth and yield on tomatoes in alluvial soil.
