“…The meter used a green tristimulus filter, a black cavity at 0.00, standard white enamel reflectance plaques, and was visually calibrated to a USDA fry color standard chart [USDA, (17)]. This procedure is similar to that recently reported by Shock et al (15). Chart colors 3 and 4 are dark brown and are objectionable to consumers.…”

Potato growers in the Pacific Northwest suffer large economic losses in seasons with above normal temperatures, due to excess reducing sugars in tubers, which cause dark-end French fries. Our objective was to study irrigation management effects on potato quality, particularly the factors causing dark-end French fries or sugar-end syndrome. Solid-set sprinkler irrigated plots were established on potatoes at Kimberly, Idaho during , 1988 and 1989 irrigation seasons, and at Parma, Idaho in 1987 and 1988. Irrigation treatments were high and low frequency (3/week and 1/week) and two or three water application amounts referenced to estimated evapotranspiration (ET, ET+20%, and ET-20%). Neither frequency nor amount significantly affected yields. Irrigation frequency had more influence on potato quality than application amount. More frequent irrigation produced slightly higher quality tubers and lower incidence of dark-ends when fried. Soil temperature was inversely related to tuber grade quality and directly related to percentage of sugar-end tubers. Soil temperature was about 0.5 C lower under the high frequency than under the low frequency irrigation regime. On these silt loam soils, allowing available soil water to decline to 50 percent had no adverse affect on yield or quality. CompendioLos productores de papa en el noroeste del Pacifico sufren grandes perdidas econOmicas en las temporadas con temperaturas por encima de lo normal, debido a un exceso de azticares reductores en los tuberculos, lo cual provoca un oscurecimiento en los extremos de las papas fritas a la francesa. El objetivo fue estudiar los efectos del manejo de la irrigaciOn sobre la calidad de la papa, en especial de los factores que causan el oscurecimiento de los extremos de las papas fritas a la francesa o sindrome de azticar terminal. Se establecieron parcelas irrigadas por un sistema solido de aspersion, para papas en Kimberly, Idaho durante las temporadas bajo riego de 1987, 1988 y 1989, y ana) y dos o tres cantidades de agua aplicada referidas a la evapotranspiraciOn estimada (ET, ET + 20%, y ET-20 %). Ni la frecuencia ni la cantidad afectaron significativamente los rendimientos. La frecuencia de riego tiene mayor influencia sobre la calidad de la papa que la cantidad aplicada. Riegos mas frecuentes dan lugar a tuberculos de calidad ligeramente superior y una menor incidencia de terminales oscuros cuando se les &ie. La temperatura del suelo estuvo inversamente relacionada al grado de calidad del tuberculo y directamente relacionada al porcentaje de tuberculos con el sindrome de azUcar terminal. La temperatura del suelo fue aproximadamente 0.5 C menor bajo alta frecuencia de riego comparada con aquella observada a baja frecuencia de riego. Los suelos de los lugares mencionados (migajones cenagosos) que permiten que el agua disponible disminuya hasta 50%, no tuvieron efecto adverso sobre el rendimiento o la calidad.

“…Both are dependent on agrotechnical and environmental factors, but primarily on the potato cultivar (Shock et al 1993;Storey and Davies 1992;Yusuph et al 2003;Zaag 1980;Zimnoch-Guzowska and Flis 2006). In our study, as in studies by Jabłońska-Ceglarek and Wadas (2005); Wadas et al (2003Wadas et al ( , 2006 and Wadas (2007), higher starch and dry mass contents were found in tubers cultivated under agro-textile and perforated plastic film in comparison to tubers cultivated without any cover.…”

The aim of this study was to evaluate the effects of cover type (control, agro-textile or perforated plastic film) and harvest date (60 or 75 days after planting and at full physiological maturity) on the yield, quality and cost-effectiveness of early harvest potato cultivation. The study was conducted in the years 2008-2011, at the Gorzyń Experimental-Education Laboratory for Soil and Plant Cultivation, Gorzyń Branch, part of the University of Natural Sciences in Poznań. The experiment was set up in a split-plot randomized block design with four replications. Covers increased the total and marketable tuber yields at early harvest dates, in particular on the 60th day after planting, compared to the reference. Tubers cultivated under covers were also found to contain higher amounts of dry matter and starch than those which were not covered. The proportion of tuber fractions with a diameter between 4.6 and 5.5 cm and above in the total yield was found to be strongly dependent on cover type. The proportion of these fractions was significantly lower under plastic film than under Agro-textile. Over the 3 years cycle, high gross margins were achieved on the 60th and 75th days after planting with perforated film and agro-textile.Resumen El propósito de este estudio fue evaluar los efectos del tipo de cobertura (testigo, agrotextil, o plástico perforado) y fecha de cosecha (60 o 75 días después de la siembra y a madurez fisiológica total) sobre el rendimiento, calidad y costo-efectividad en el cultivo de papa de cosecha temprana. El estudio se desarrolló en los años 2008-2011, en el Laboratorio Experimental de Educación para Suelo y Cultivo de Plantas Gorzyń, rama de Gorzyń, perteneciente a la Universidad de Ciencias de la Vida en Poznań. El experimento se estableció en un diseño de bloques divididos al azar con cuatro repeticiones. El propósito del trabajo fue evaluar los efectos de tipo de cobertura (testigo, agro-textil, o capa de plástico perforada) y fechas de cosecha (60 y 75 días después de la siembra, a madurez fisiológica completa de los tubérculos) sobre rendimientos y calidad de tubérculos, así como en los resultados económicos del cultivo de papa para cosecha temprana. Las coberturas aumentaron los rendimientos de tubérculo total y comercial en las fechas de cosecha temprana, en particular a los 60 días después de la siembra, al compararse con la referencia. De la misma manera, se encontró que los tubérculos bajo cobertura contenían mayores cantidades de materia seca y almidón que los no cubiertos. El margen alto de retribución neta se alcanzó a los 60 y 75 días después de la siembra, en los tratamientos con plástico perforado y agrotextil, que fueron usados en un ciclo de tres años.

“…Russet Burbank potato occasionally suffers from a tuber quality problem called "sugar end" or "dark end" syndrome. The phenomena, in which one end of the tuber has higher levels of reducing sugars and fries darker than the remainder of the tuber, is believed to be caused by stress during tuber growth (8,9,10) and may be related to water management (18,20).…”

A survey of growers in the Treasure Valley of western Idaho/eastern Oregon indicated that Russet Burbank potato tends to produce better quality tubers under sprinkler irrigation than with furrow irrigation. Irrigation plot studies were carried out over 3 years on 2 sites to determine if these differences were a result of commonly-used management practices or inherent in the irrigation method. With good water management, irrigation method did not affect yields, but sprinkler irrigation produced tubers with slightly better visual quality and much lower incidence of sugar ends. The reasons for better quality with sprinkler-irrigation were projected to include: 1) less water stress since sprinklers can more uniformly apply the small, frequent irrigations that potato requires; 2) better nitrogen management since furrow applications often leach nitrogen from the root zone; and 3) lower soil temperatures due to sprinkler water evaporative cooling.

Las razones de una mejor calidad con la irrigaciOn por aspersi6n fueron estimadads e incluyeron: 1) menor estres al agua desde que los aspersores pueden aplicar mas uniformemente las irrigaciones pequefias y frecuentes que la papa requiere; 2) un mejor manejo del nitrogeno desde que la irrigaciOn por surco arrastra frecuentemente, por percolaciOn, el nitrogeno de la zona de la raiz; y 3) menores temperaturas del suelo debido al enfri-
