Abstract
Pin-Point (PP) irrigation is being used by rice producers in the southern US to suppress red rice (Oryza sativa), the major weed in rice production. In PP irrigation, germinated seed is dropped into the floodwater. After 24 h the field is drained, remains moist for 3 to 5 days, then reflooded until near harvest. Little is known about water use of the PP method in comparison to the conventional Flush-Flood (FF) method in which germinated seed is also dropped into the floodwater and the field is drained after 24 h, similar to PP, or the field is drill-seeded, flooded and drained, but permanent flood is delayed for 30 to 35 days. During this 30 to 35 days non-flood period, flushing (periodic irrigation) is used to maintain seedling contact with the soil and prevent water stress. Water use of PP and FF irrigated rice was studied during 1994 and 1995 growing seasons near Beaumont, TX. Three plots were subjected to the PP irrigation technique and three to the FF method. A flow meter measured irrigation water applied, and lysimeters measured evapotranspiration, transpiration, and evaporation. The FF method required an average of 113 mm more irrigation water than the PP method, due to flushing of FF plots during the non-flood period. Evapotranspiration (ET) was higher for PP plots during the period when FF plots were dry. During the flood period, ET in FF plots was higher than in PP plots in 1994, due to mainly a lower leaf area index and a more open canopy which led to greater evaporation from the water surface. No differences in ET were found in 1995. Stomatal conductance was lower in FF plots during the non-flood period, indicating some degree of water stress. Irrigation method did not affect yield, but the PP method reduced time to 100% heading by 5 to 7 days. These results suggest that the PP method can be useful not only to suppress red rice, but also to save water and produce an earlier maturing crop. Early maturity is particularly important in areas where ratoon cropping is practiced. MenosAbstract

Se puede mencionar como antecedentes trabajos realizados en los comienzos de los 2000 por el Ing. Agr. Sergio Carballo en un trabajo de validación INIA/PREDEG.
Las principales conclusiones de ese trabajo fueron las siguientes: La HM redujo efectivamente la brotación y sus efectos comenzaron a ser relevantes a partir de junio en cebollas valencianas. Las cebollas tratadas tuvieron menos de un 20% de brotado en agosto, mientras que el testigo sin tratar alcanzó un 60% de brotación. No se evitó con la HM la pérdida de calidad del producto por defectos tales como pudriciones y ablandamiento. Tanto la aplicación de HM al comienzo del vuelco del follaje, así como con 22% de plantas volcadas redujeron la brotación y no se observaron diferencias entre estos tratamientos. |
