ResumoespanolPara evaluar el deshoje inducido sobre la productividad del platano (Musa AAB cv. Harton), se hizo un estudio en el municipio Colon, estado Zulia. Se seleccionaron 16 plantas de platano en su primera semana de floracion. Los tratamientos consistieron en realizar el deshoje de tal forma de dejar plantas con seis hojas (T1), plantas con ocho hojas (T2), plantas con 10 hojas (T3) y plantas sin deshojar como testigo, con 12 hojas o mas (T4), para un total de cuatro tratamientos con cuatro plantas como repeticion con un modelo estadistico totalmente aleatorizado. A las doce semanas, se cosecharon las plantas, y se diagnostico el avance de sigatoka negra con base a la escala modificada de Stover. Las variables medidas fueron peso del racimo (PR), numero de hojas al momento de la cosecha (NH/P), numero de dedos por racimo (ND/R), relacion porcentual peso de la fruta/peso del racimo (PF/PR), caracteristicas morfologicas de los frutos: peso (PF), longitud (LD) y diametro (DD). Se clasificaron los dedos con base a dichas caracteristicas. De acuerdo a los resultados solo hubo diferencia estadistica significativa (P EnglishIn order to evaluate the induced defoliation on the plantain productivity, a study was carried out in Colon municipality, Zulia state. Sixteen first week flowering plants were selected. Treatments were carried out as follows: four were let on six leaves (T1), four with eight leaves (T2), four with ten leaves (T3) and four with twelve or more leaves (T4: witness), for a total of four treatments with four plants like replicate by following a statistical model totally at random. The plants were harvested at twelve weeks and Black Sigatoka was diagnosed on base to Stover modified scale. Variables measured were: Bunch weight (PR), number of leaves at the moment of harvest (NH/P), number of fingers or fruits per bunch (ND/R), perceptual relationship between fruit weight/bunch weight (PD/PR), fruits morphological characteristics (weight (PF), length (LD) and diameter (DD)). Fruits were classified with base at these characteristics. Agreed with the results obtained, only had significant statistics difference (P
