Introducción. La Altillanura colombiana atraviesa por un proceso de transformación, marcado por la expansión de su frontera agrícola. En la región, se está implementando una agenda de investigación que busca desarrollar y validar tecnologías promisorias para el mejoramiento de la productividad y la sostenibilidad de los sistemas de producción agropecuarios. La evaluación económica juega un papel importante en priorizar actividades, asignar recursos y guiar la investigación agrícola hacia objetivos de desarrollo rural. Objetivo. El objetivo de este trabajo fue implementar una evaluación económica ex-ante para estimar los resultados e impactos potenciales de la nueva línea promisoria de arroz L23 desarrollada para la Altillanura colombiana. Materiales y métodos. El impacto se midió en el genotipo de arroz L23, desarrollado en colaboración por la Corporación Colombiana de Investigación Agropecuaria (AGROSAVIA) y el Centro Internacional de Agricultura Tropical (CIAT), para la Altillanura colombiana. La evaluación ex-ante efectuada combinó un análisis de presupuestos parciales con información de pruebas experimentales y un modelo de excedentes económicos. Resultados. Los dos enfoques metodológicos fueron consistentes y mostraron que con la adopción del genotipo L23, en al menos 29,7 %, se podría conseguir una rentabilidad del 17,1 % para los productores de arroz de la Altillanura, debido al aumento esperado del rendimiento en el cultivo. Sin embargo, un análisis de sensibilidad de los supuestos, alerta que un bajo nivel potencial de adopción junto a cambios no significativos en rendimiento convertiría la investigación y desarrollo del nuevo genotipo en no factible a nivel económico. Conclusión. Para que la investigación, desarrollo e introducción del genotipo de arroz L23 sea rentable, se requiere un proceso de diseminación que permita la reproducción de la semilla y facilite el acceso a los productores, para que así puedan alcanzar mayores niveles de adopción. 2019-09 2019-09-19T19:22:28Z 2019-09-19T19:22:28Z Journal Article https://hdl.handle.net/10568/103687 es Open Access Universidad de Costa Rica Marin Salazar, Diego Armando; Andrade, Robert; Labarta, Ricardo; Vásquez-Urriago, Ángela Rocío; Caicedo Guerrero, Samuel (2019).
