| description | Tapping systems with stimulation are used to minimize costs and improve latex yield. For this, tapping systems with different frequencies and with or without Ethrel® stimulation and fertilizer levels were evaluated in a 9-yearold crop of FX3864 of Hevea brasiliensis in Barrancabermeja, Santander. In this study, a split plot design with randomized complete blocks was used, where the tapping systems with different frequencies with or without stimulation were considered as the principal plot and the fertilization treatments with combined dosages of N, P and K were considered as the subplots. The dry rubber yield, bark consumption, tapping panel dryness incidence, dry rubber content and profitability were considered as response variables. The systems d/3 E and d/4 E obtained the highest yield (1,446 and 1,281 kg ha-1 yr-1, respectively), with significant differences with the systems d/3 S.E and d/5 E. For the fertilization treatments, there were no significant differences. Notwithstanding, the highest yields were obtained in the 40-40-40 kg ha-1 and 80-80-80 kg ha-1 of N, P and K balanced treatments. The higher foliar levels of N, P, K and Ca were founded in the d/4 E system. According to these results, the d/4 E tapping system is recommended to be the most profitable under different tapping yields, with less bark consumption (3.86 cm), longer life plantation (3.85 years) and less disease panel incidence. |

Los sistemas de sangría con estimulación se usan para minimizar costos y aumentar la producción de látex. Por ello, se evaluaron sistemas de sangría con diferentes frecuencias con y sin estimulación con Ethrel® y niveles de fertilización en un cultivo del FX3864 de Hevea brasiliensis de 9 años de edad en Barrancabermeja, Santander. El estudio se realizó con un diseño de parcelas divididas, distribuido en bloques al azar, considerando como parcela principal los sistemas de sangría con diferentes frecuencias con y sin estimulación y como subparcela los tratamientos de fertilización con dosis combinadas de N, P y K. La producción de caucho seco, consumo de corteza, incidencia de seca fisiológica, contenido de caucho seco y la rentabilidad económica se consideraron como variables de respuesta. La producción más alta se obtuvó con los sistemas d/3 E y d/4 E (1.446 y 1.281 kg ha-1 año-1, respectivamente), con diferencias significativas con los sistemas d/3 S.E y d/5 E. Entre los tratamientos de fertilización no se encontró diferencias significativas, aunque las mayores producciones se obtuvieron con los niveles 40-40-40 kg ha-1 y 80-80-80 kg ha-1 de N, P y K. En cuanto a los mayores niveles foliares de N, P, K y Ca se encontraron en el sistema d/4 E. Con estos resultados se recomienda el sistema de sangría d/4 E por tener la mejor rentabilidad económica bajo diferentes rendimientos del sangrador, menor consumo de corteza (3,86 cm), mayor vida útil de la plantación (3,85 años) y menor incidencia de enfermedades de panel.
