Abstrakt: | Inoculation with Bacillus subtilis is a promising approach to increase plant yield and nutrient acquisition. In this context, this study aimed to estimate the B. subtilis concentration that increases yield, gas exchange, and nutrition of lettuce plants in a hydroponic system. The research was carried out in a greenhouse in Ilha Solteira, Brazil. A randomized block design with five replications was adopted. The treatments consisted of B. subtilis concentrations in nutrient solution [0 mL "non-inoculated", 7.8 × 10 3 , 15.6 × 10 3 , 31.2 × 10 3 , and 62.4 × 10 3 colony forming units (CFU) mL -1 of nutrient solution]. There was an increase of 20% and 19% in number of leaves and 22% and 25% in shoot fresh mass with B. subtilis concentrations of 15.6 × 10 3 and 31.2 × 10 3 CFU mL -1 as compared to the non-inoculated plants, respectively. Also, B. subtilis concentration at 31.2 × 10 3 CFU mL -1 increased net photosynthesis rate by 95%, intercellular CO Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
