• Abstract:

  The study evaluated the efficacy of several native Trichoderma strains on the growth of Jala maize. Soil samples were collected from 15 locations in Nayarit and Oaxaca, where 51 strains were isolated, with T. viride, T. asperellum and T. harzianum standing out. Of these, T. viride showed the best performance in solid and liquid media, with rapid growth and high biomass production, with strain 48 standing out. In germination and root development, T. asperellum (strain 69) and T. harzianum (strain 42) also showed good results, although they were surpassed by T. viride. Soils with pH close to neutral favored the diversity of Trichoderma, highlighting the "Tierra Oaxaca" as one of the richest in strains. Trichoderma applications significantly improved the germination speed index, root length and diameter of the treated plants, which evidences its potential as a biofertilizer and growth promoter. In conclusion, T. viride strains, particularly strain 48, showed better experimental performance in strengthening the yield of Jala maize, while T. asperellum and T. harzianum offer complementary applications at different stages of the crop.
