Abstract
The northern oil palm area of Colombia presents low rainfall conditions therefore it is necessary to use irrigation at least five months during the year. The most common irrigation system used in this area is the surface method, which given its inefficiency, it doesn't allow supplementing the low environmental supply. The project aimed at quantifying the water use efficiency in a representative oil palm crop of the northern area, getting a total value of 5,8 percent, representing a conduction efficiency of 35,6 percent and 16,1 percent of application. Moreover, other irrigation alternatives were assessed from the technical and economic standpoints, other surface irrigation application and canal lining, in order to determine potential efficiency conditions En la zona palmera ubicada al norte de Colombia, se presentan condiciones de baja oferta de precipitación que hacen necesario la aplicación de riego durante por lo menos cinco meses al año. La mayor parte de los sistemas de riego existentes en esta zona, son sistemas de superficie que, por su ineficiencia, no permiten complementar la baja oferta ambiental. El proyecto contempló cuantificar la eficiencia del uso del agua en una plantación palmera representativa de la zona, obteniéndose un valor total de 5,8 por ciento, representado en una eficiencia de conducción de 35,6 por ciento y 16,1 por ciento de aplicación. Igualmente, se evaluaron, técnica y económicamente, alternativas de aplicación de riego por superficie y de revestimiento de canales, con el propósito de determinar condiciones de eficiencia potenciales.
