| description | The use of Trichoderma spp. in organic agriculture is important due to its wide mode of action that includes: the segregation of secondary metabolites that induce the production of phytoalexins in plants and its antagonistic capacity, besides the antibiosis that cause the degradation of the cell walls of other pathogens inhibiting their development. The objective was to evaluate the effect of four strains of Trichoderma spp. on morphological parameters and yield of maize under field conditions. The research was conducted at the Technical University of Machala, Faculty of Agricultural Sciences, "Santa Inés" experimental farm. An experimental design of completely randomized blocks was used, 90 plants were evaluated per treatment, 4 treatments, 3 doses, 3 repetitions per dose, 10 plants per repetition in the variables previously mentioned, the treatments were: T1: Trichoderma asperellum; T2: Trichoderma melanomagnum; T3: Trichoderma spirale; T4: Trichoderma reesei in three doses. The results obtained indicate that the variables that presented statistical differences were: height of plant with T. spirale obtained 239,630 cm, number of leaves above the cob in T. melanomagnum and T. spirale were higher with 7,060 and 7,130 respectively, cob length in T. melanomagnum with 13,687 cm, cob diameter had similar values with the four strains, seed weight with T. melanomagnum obtained 59,410 g and seed moisture in T. asperellum with 26,933%. It's concluded that the strains T. asperellum and T. melanomagnum with doses x1010 and x1011 CFU obtained the best yields |

El objetivo fue evaluar el efecto de cuatro cepas de Trichoderma spp sobre parámetros morfológicos y rendimiento del cultivo de maíz bajo condiciones de campo. La investigación se realizó en la Universidad Técnica de Machala, Facultad de Ciencias Agropecuarias, granja experimental “Santa Inés”. Se usó un diseño experimental de bloques completamente al azar, se evaluaron 90 plantas por tratamiento, 4 tratamientos, 3 dosis, 3 repeticiones por dosis, 10 plantas por repetición en las variables anteriormente mencionadas, los tratamientos fueron: T1: Trichoderma asperellum; T2: Trichoderma melanomagnum; T3: Trichoderma spirale; T4: Trichoderma reesei en tres dosis. Los resultados obtenidos indican que las variables que presentaron diferencias estadísticas fueron: altura de planta con T. spirale obtuvo 239,630 cm, número de hojas arriba de la mazorca en T. melanomagnum y T. spirale fueron mayores con 7,060 y 7,130 respectivamente, longitud de mazorca en T. melanomagnum con 13,687 cm, diámetro de la mazorca posee valores similares con las cuatro cepas, peso de semilla con T. melanomagnum obtuvo 59,410 g y humedad de semilla en T. asperellum con 26,933%. Se concluye que las cepas T. asperellum y T. melanomagnum con las dosis x1010 y x1011 UFC obtuvieron los mejores rendimientos.
