The application was by immersion of cuttings before sowing for 0, 5, 10 and 15 minutes with combination doses of 0, 50 and 100% of NPK mineral fertilizer in a randomized block design with three replications (12 treatments-combinations). During the harvest (130 days after planting), some measurements related to yield components were recorded on ten randomly selected plants from each plot. All treatments with &lt;em&gt;Pseudomonas&lt;/em&gt;’ immersion showed a positive productive response. With 100% NPK and the immersion in the biofertilizer for 15 min showed the highest yield (56.09 tha&lt;sup&gt;-1&lt;/sup&gt;), followed by the other treatments with 100% NPK and without statistical differences among them. The treatment with 50% NPK and the immersion in Pseudomonas for 15 min (49.58 tha&lt;sup&gt;-1&lt;/sup&gt;) had no statistical differences with the control variant (100% NPK, 51.60 tha&lt;sup&gt;-1&lt;/sup&gt;). Based on the results, it can be concluded that this biofertilizer could be an appropriate alternative to increase the sweet potato yield, saving the 50% of the current quantity of the recommended mineral fertilizer, through a more friendly environmental techniques to promote a sustainable, efficient and productive agriculture.&lt;/p&gt;}, number={2}, journal={Asian Journal of Applied Sciences}, author={Santana-Fernández, Alexander and Beovides-García, Yoel and Simó-González, Jaime Enrique and Pérez-Peñaranda, María Cristina and López-Torres, Jorge and Rayas-Cabrera, Aymé and Santos-Pino, Arletys and Basail-Pérez, Milagros}, year={2021}, month={Apr.} }
