| Summary, etc |
La presente investigación se realizó en una parcela del Instituto Técnico de Agricultura, ubicada en Bárcena, Villa Nueva, Guatemala, con el objetivo de determinar el efecto de seis frecuencias de riego sobre el rendimiento y evapotranspiración de cebolla (Allium cepa). Se utilizó un diseño experimental de bloques al azar con cuatro repeticiones y frecuencias de riego de 4, 8, 12, 16, 20 y 24 días. Se evaluaron rendimiento de bulbos, producción de plantas completas, número de plantas vivas y consumo hídrico del cultivo. Los resultados indicaron que la frecuencia de riego de 16 días produjo el mayor rendimiento de bulbos con 25.300 T.M./Ha., mientras que el riego cada 8 días presentó el mayor rendimiento de plantas completas con 54.733 T.M./Ha. |
