Possibility of red rice (Oryza sativa L.) control through a prolonged flooding
Main Article Content
Abstract
desde 1998 al 2000, se desarrolló un experimento para el
control del arroz rojo. Se utilizaron macetas de un área de 0.25 m2,
sembrándose en éstas 20 semillas de arroz rojo a una profundidad
de 3 cm. Los manejos del agua fueron desde inundación y
después desagüe hasta pases de agua y después inundación.
Se logró un control total y efectivo a partir de los 40 días
cuando se utilizó el manejo del agua, inundación y después
desagüe, respecto al método tradicional (pases de agua y después
inundación) dejando el área que estaba afectada por esta
maleza, sin la presencia de ella. En los meses de mayor temperatura,
se observó una influencia marcada en el aumento de
esta variable en el agua de las macetas, lo que influyó positivamente
en el control del arroz rojo.
