This study aimed to assess the potential impact of mycorrhizae fungi and nitrogen fertilization on the growth and yield of white maize in the Andean conditions of Loja, Ecuador. The field trial was conducted in Loja, Ecuador, using a completely randomized design arranged in a bifactorial scheme. The first factor involved the mycorrhizae inoculation, comprising three doses: 0 (control), 330 and 660 spores per plant of the mycorrhizal fungi. The second factor focused on nitrogen fertilizer, with three doses: 0 (control), 40 and 80 kg ha-1 of nitrogen applied throughout the crop cycle. The combination of mycorrhizal inoculation and nitrogen fertilization promoted plant height and stem diameter: the best results were attained when applying 330 spores per plant of mycorrhizae and 80 kg ha-1 of nitrogen. Independent nitrogen and mycorrhizal application significantly increased the cob number per plant, grain weight and yield, reaching a maximum of 9.9 t ha-1. Notably, mycorrhizae inoculation significantly increased grain nitrogen content by 7 % compared to the control, which suggests its potential to enhance the dietary quality and food security of the Andean population. El maíz blanco desempeña un papel fundamental en la alimentación de las comunidades andinas de Ecuador, especialmente en las áreas rurales y empobrecidas. Este estudio evaluó el impacto de las micorrizas y la fertilización nitrogenada en el crecimiento y rendimiento del maíz blanco en las condiciones andinas de Loja, Ecuador, usando un diseño aleatorizado con arreglo bifactorial. El primer factor implicó la inoculación de micorrizas, comprendiendo tres dosis: 0 (control), 330 y 660 esporas por planta. El segundo factor se centró en el fertilizante con tres dosis: 0 (control), 40 y 80 kg/ha de nitrógeno. La combinación de micorrizas y fertilización nitrogenada favoreció la altura de las plantas y el diámetro del tallo: los mejores resultados se lograron al aplicar 330 esporas por planta y 80 kg/ha de nitrógeno. La aplicación independiente de nitrógeno y micorrizas incrementó el número de mazorcas por planta, el peso del grano y el rendimiento, alcanzando un máximo de 9,9 t/ha. Notablemente, las micorrizas elevaron significativamente el contenido de nitrógeno del grano en un 7 % en comparación con el control, lo que sugiere su potencial para mejorar la calidad de la dieta y la seguridad alimentaria de la población andina.
