    This research was carried out at the Technical University of Cotopaxi- CEASA Campus with the objective of evaluating the effectiveness of the fertibacter biofertilizer based (Bacillus subtilis and Pseudomonas fluorescens) at four doses and two frequencies in the production of lettuce seedlings and its response in the field, this allowed the analysis and comparison of the variables evaluated; Eight fertibacter solutions were prepared as treatments, 0% solution 0ml in 1 liter of water, 2% with 2 ml in 1 liter of water, 4% with 4ml in 1 liter of water and 6% solution with 6ml in 1 liter of water, with two application frequencies, the first every 7 days and the second every 15 days in order to compare the yields in germination percentage, cotyledon height, plant height, number of leaves, root length, root volume and degree of chlorosis in the production of seedlings and in the field, plant height, percentage of head formation, degree of maturity, weight and equatorial diameter. A split block experimental design (DBD) was applied. A water volume of 250 ml of water was used for each of the treatments; variable 1, germination percentage (PG), variable 2 cotyledon height (AC), variable 3 plant height (AP), variable 4 number of leaves (NH), variable 5 root length (LR), variable 6 root volume (VR), variable 7 degree of chlorosis (GC), variable 8 plant height (AP), variable 9 head formation percentage (DC), variable 11 degree of maturity (GM), variable 11 cabbage weight (W), variable 12 cabbage weight (W), variable 12 cabbage weight (W), variable 13 head formation percentage (DC), variable 14 head weight (W), variable 14 head weight (W), variable 15 head weight (W), variable 9 head formation percentage (DC), variable 11 degree of maturity (GM), variable 12 cabbage weight (PR) and variable 13 equatorial diameter (ED), significance tests were performed for factor A frequencies, factor B dose and interaction of the two factors where there was a significant difference, the Tukey test was performed; In the analysis of the variables, it was determined that the optimum application frequency is every 7 days for both seedling production and field yield. In terms of doses, dose 4 (6 ml in 1 liter of water) showed better performance in seedling production with an average germination rate of 97.71%, a plant height of 7.18 cm, a number of leaves of 6.68, a root length of 8.09 cm, a root volume of 5.09 cm³ and a degree of chlorosis of 67.22%. In the field, this same dose also proved to be the most effective, with a head formation of 53.88%, a maturity grade of 2.43, a lettuce weight of 519.88 grams and an equatorial diameter of 15.95 cm. In addition, dose 3 (4 ml in 1 liter of water) also showed good performance. Among the treatments evaluated, the most outstanding in the different variables were T4, T8, T3 and T2.
