Principi, A. basal rot sorghum Sorghum bicolor tillage and sowing podredumbre basal sorgo Sorghum bicolor labranza y siembra This work was carried out on a grain sorghum crop (Sorghum bicolor (L.) Moench) cv. Frontier 4122 sowed according to a experimental design in split plots with four replications. The principal fungi associated with sta'k rot in natural infections belong to the Fusarium spp. group, being the most important F. moniliforme Sheldon; Macrophomina phaseoli (Maublanc) Ashby, Nigrospora sp. and Helminthosporum sp. were present very few times. Heavy rains during the growing season followed by dry conditions close to riping point helped stalk rot. The incidence of disease was notably reduced under either minimum tillage or zero tillage practices as compared to conventional tillage when early tilled soil was not carried out; when it was performed the incidence of disease highly decreased under minimum tillage compared with conventional and zero tillages. Este trabajo fue realizado sobre un cultivo de sorgo granífero (Sorghum bicolor (L). Moench) cv. Frontier 4122 sembrado según un diseño experimental en parcelas divididas con cuatro repeticiones. Los principales hongos relacionados a la podredumbre basal en infecciones naturales pertenecen al grupo Fusariumspp. siendo el más importante F. moniliforme She:don; estando presentes muy pocas veces Macrophomina phaseoli (Maublane) Ashby, Nigrospora sp. y Helminthosporium sp. El elevado milimetraje de lluvias registrado durante el cultivo seguido de un período de carencia hacia la maduración del grano pueden haber favorecido la podredumbre basal.La incidencia de la enfermedad disminuyó notablemente en los sistemas de labranza mínima y cero respecto a la labranza convencional cuando no se efectuó el laboreo anticipado del suelo; cuando éste se realizó, la incidencia de la enfermedad fue marcadamente menor para la labranza mínima comparada con los sistemas convencional y cero.
