La esterilización de sustratos para vivero disminuye la población de microorganismos benéficos en el medio que rodea la raíz y puede resultar en un pobre crecimiento de la planta; la vermicomposta y los hongos micorrízicos arbusculares (HMA) podrían mejorar su desarrollo. El objetivo de este experimento fue analizar el efecto de la vermicomposta y la inoculación de HMA sobre el crecimiento inicial de plántulas de durazno [Prunus persica (L.) Batsch.] en sustrato esterilizado. Plántulas de durazno germinadas en perlita estéril fueron distribuidas en cuatro tratamientos resultado de la combinación de dos factores y dos niveles cada uno: con/sin vermicomposta en el sustrato y con/ sin inoculación con HMA al momento del trasplante. Las plántulas se distribuyeron completamente al azar dentro de un invernadero de vidrio durante el estudio. La incorporación de vermicomposta al sustrato y la inoculación de HMA, así como su combinación, resultaron en un decremento de clorofila total (p < 0.05) a los 108 días después de plantación (DDP). Al final del experimento (180 DDP), la inoculación con HMA resultó en una colonización de raíces mayor al 70 % de su longitud total, pero este efecto fue eclipsado por la vermicomposta. El peso seco de tallo y raíz y el diámetro de tallo fueron superiores (p < 0.01) con el uso de vermicomposta, pero la inoculación de HMA no tuvo efecto en estas variables. Se concluye que es más recomendable la vermicomposta que la inoculación con HMA para estimular el crecimiento de plántulas de durazno durante los primeros seis meses en sustrato esterilizado.
