Abstract
El avellano europeo (Corylus avellana L.) es un frutal que produce avellanas, fruto seco de alta demanda por su valor nutricional, destacando su contenido de ácidos grasos, que representa cerca del 60 % de su peso. En Chile, su cultivo ha crecido rápidamente, aunque enfrenta limitaciones por la escasez hídrica. Ante este desafío, se requieren estrategias que mejoren la eficiencia en el uso del agua, como el riego deficitario controlado (RDC), el cual reduce o suspende el riego en fases específicas del desarrollo. En este estudio se evaluó el efecto del RDC en avellanos plantados en Ñiquén en el año 2016, regados por goteo. Se aplicaron seis tratamientos durante dos temporadas, en donde se repuso en distintos porcentajes de la Evapotranspiración de cultivo (ETc). Los resultados indicaron que, a pesar de las restricciones hídricas, no se encontraron diferencias significativas en el contenido de ácidos grasos en comparación con los tratamientos con reposición completa o superior al 100 % de la evapotranspiración, con valores entre 534 y 722 mg/g de muestra. Este estudio respalda el uso de prácticas sostenibles que promuevan la resiliencia agrícola y la seguridad alimentaria.
The European hazelnut (Corylus avellana L.) is a fruit tree that produces hazelnuts, a nut in high demand for its nutritional value, especially its fatty acid content, which represents about 60 % of its weight. In Chile, its cultivation has grown rapidly, although it faces limitations due to water scarcity. Faced with this challenge, strategies are needed to improve water use efficiency, such as controlled deficit irrigation (CDI), which reduces or suspends irrigation at specific stages of development. This study evaluated the effect of CDI on drip-irrigated hazelnut trees planted in Ñiquén in 2016. Six treatments were applied over two seasons, during which crop evapotranspiration (ETc) was replenished at different percentages. The results indicated that, despite water restrictions, no significant differences were found in fatty acid content compared to treatments with complete or greater than 100% evapotranspiration replacement, with values ranging from 534 to 722 mg/g of sample. This study supports the use of sustainable practices that promote agricultural resilience and food security.
