Mexico ranks fourth in the world in chili pepper (Capsicum annuum L.) production, which means that this crop is of great economic importance to Mexican society. However, the excessive and/or unbalanced use of chemical fertilizers has caused the degradation of soil properties and, consequently, a decrease in crop yields. One alternative to reducing the use of chemical fertilizers is the use of beneficial microorganisms, which can provide nutrients. Therefore, the objective of the study was to evaluate the effect of Azospirillum brasilense, Bacillus subtilis and Serendipita indica, applied as a complement to chemical fertilization under two cultivation systems (greenhouse and open field) on the growth, quality and yield of the chili crop. The studies were carried out under a factorial arrangement with two factors: the chemical fertilization factor with two levels (70 and 100%), and the microorganisms factor with eight levels (no microorganisms, Azospirillum brasilense + Bacillus subtilis + Serendipita indica, S. indica, A. brasilense, B. subtilis, A. brasilense + S. indica, B. subtilis + S. indica and B. subtilis + A. brasilense). Measurements were made of variables related to the vegetative growth stage and variables related to the quality and yield of the crop during harvest. The combination of A. brasilense and S. indica had a positive effect on the growth, quality, and yield of the chili pepper crop.
