Tomato (Solanum lycopersicum L.)is one of the world's most prolific vegetables . Researchers are still looking for solutions to improve crop technology using plant protection and stimulation products that are neither harmful to the environment or the plants they treat. Many technologies for cultivating and treating plants with Bacillus spp. have been developed. For this reason, we analyzed the influence of PGPR on two tomato hybrids Cocete F1 and Nissos F1 in the greenhouse. The results showed that there weren’t considerable differences in the quantitative characteristics of plant studied. Regarding stem thickness, the variants had values between 0.5 cm and 0.7 cm. The number of leaves was 16.8 = F1 Cocete 15.9 = F1 Cocete+PGPR, 16.6 = Nissos F1, 16.5 = Nissos F1 + PGPR). The plants height for Cocete F1 was 193.1 cm and 188.1 cm for Cocete F1 + PGPR, while for Nissos F1, the plants had 218.9 cm and 211.3 for Nissos F1 + PGPR. In terms of inflorescences number, Cocete F1 recorded 6.4 and 5.7 for Cocete F1 + PGPR whereas Nissos F1 had 5.1 and Nissos F1 + PGPR 4.9. Referring to the flowers number, the hybrid Cocete F1 in both variants registered similar values (30 flowers/plant) but Nissos F1, Nissos F1 + PGPR had 24.8 and 26.7, respectively. The number of fruits per plant was 14.8 for Cocete F1 while other variants produced 16 fruits/plant.
