“…According to Yuan et al (2003) water stress reduced photosynthetic efficiency, but the drought during the periods of tuber initiation and bulking had the most drastic effect on the yield. However, in some circumstances, potato can tolerate limited deficit irrigation before tuber set without significant reductions in external and internal tuber quality (Shock et al 1992). These results suggest that, for drip-irrigated potato grown in sandy soil texture, subsurface drip system is a better management option affecting crop yields and their components.…”

Efficient water delivery systems such as drip irrigation can contribute towards increasing crop yield potential, improving crop water and fertilizer use efficiency. However, critical management considerations such as subsurface drip irrigation are necessary to attain improved irrigation efficiencies and production benefits particularly under arid regions. The objective of this study was to determine the effect of two irrigation methods, surface and subsurface drip irrigation combined with four irrigation levels, 100, 80, 60 and 40% of crop evapotranspiration on yield and yield components of potato grown on sandy soil. The field experiments were conducted in the years 2008 and 2009. In terms of soil water availability to plants, subsurface drip provided more favorable growth conditions for plant growth and maintained higher soil water content at the root zone, which resulted in a significant higher potato yield compared to surface drip irrigation. The difference between the two irrigation methods on yield components was concentrated on the mean tuber weight per plant, while no significant difference was found on the tuber number per plant. Reducing the amounts of applied water significantly decreased total potato yield and its components. Under subsurface drip irrigation, reducing amounts of applied water to 80% ETc gave comparable yield and yield components to surface drip at full irrigation supply, indicating that 20% irrigation water can be saved without affecting the potato yield. At all irrigation levels, subsurface drip recorded higher water use efficiency (WUE) over surface drip. Maximum value was observed at 40% ETc. Fertilizer use efficiency (FUE) was also higher under subsurface drip and reduced significantly under both irrigation methods with increasing water deficit. These results suggested that subsurface drip offers the potential of better water management with respect to saving and distribution of water in the root zone and to obtain maximum yield accompanied by highest water and FUE.Keywords Subsurface drip irrigation · Dry stress · Potato · Water use efficiency · Fertilizer use efficiency Die Effizienz der Unterflur-Tropfbewässerung im Kartoffelanbau unter verschiedenen TrockenstressbedingungenZusammenfassung Effiziente Bewässerungssysteme, wie Tröpfchenbewässerung können zur Steigerung des Ertragspotenzials, sowie zur Verbesserung der Wasser-und Dün-gernutzungseffizienz beitragen.

“…Type 1 sugar ends are marked by low starch and high sugars in the older, stem-end tissue while the younger, apical tissue has high starch and low sugar content (Eldredge et al 1996;Iritani 1981Iritani , 1987Weller 1973, 1980;Kleinkopf et al, 1988;Shock et al, 1987Shock et al, , 1992Shock et al, , 1993. This condition is attributed to early-season stress, is the most common type of sugar end, and is the most troublesome to processors.…”

Review Of The Sugar End Disorder In Potato (Solanum tuberosum, L.)

Processing quality has become increasingly important to the potato industry. A serious defect in product quality is the physiological disorder known as sugar ends, also referred to as dark ends, jelly ends, translucent ends, and/or glassy ends. Symptoms of the most common type of sugar end include relatively low starch and high sugar content in the basal end of the tuber. Tubers with the sugar end disorder produce French fries that are dark on one end, making the fries unacceptable to consumers. Sugar end potatoes cause time and profit losses at the processing plant and may require blending of loads to meet product specifications, along with the need to change processing protocols. Sugar end can be costly to growers if the tubers have insufficient quality and the crop is rejected for processing. Conditions conducive to the development of sugar ends include high soil temperatures, transitory soil moisture deficits, and insufficient or excess nitrogen fertilization. Tubers are most sensitive to these stresses during early bulking. Historically, several theories have been proposed concerning the mechanism of sugar end development. Research shows that stressed plants produce adequate amounts of assimilate to support continued tuber growth, but accumulate large amounts of sucrose in the basal tissues of the tuber immediately following stress. Accumulated evidence suggests that heat stress and water deficit induce changes in the activities of certain key carbohydrate metabolizing enzymes shifting the tuber from a starch synthesizing function to one of starch mobilization. Genetic resistance to sugar end development is known and the identified traits are highly heritable. This review summarizes sugar end investigations to-date, and presents a list of research-based crop management recommendations that assist potato producers in minimizing the potential for sugar end development in the field.Resumen La calidad de procesamiento de papa se ha vuelto cada vez más importante para la industria. Un defecto serio en la calidad del producto es el desorden fisiológico conocido como punta azucarada, referido también como punta oscura, punta translúcida y/o punta vítrea. Los síntomas de los tipos más comunes de punta azucarada incluyen bajo contenido relativo de almidón y alto contenido de azúcar en el extremo basal del tubérculo. Los tubérculos con punta azucarada producen papas fritas que tienen un extremo oscuro, haciendo la fritura inaceptable para los consumidores. Las papas con extremo azucarado causan pérdida de tiempo y ganancias a la planta procesadora y puede requerir la mezcla de lotes de papa para satisfacer las especificaciones del producto, además de de la necesidad de cambiar los protocolos de procesamiento. La punta azucarada Am. puede ser costosa para los productores si los tubérculos son de calidad insuficiente y el cultivo es rechazado para procesamiento. Las condiciones que conducen al desarrollo de este desorden incluyen altas temperaturas del suelo, deficiencia transitoria de agua e insuficiencia o exceso de ...

“…Walworth and Carling (2002) suggested that full irrigation increases the number of large tubers. When irrigation water supply before and at tuber initiation is sufficient, the number of tubers per plant increases (Shock et al 1992), while after tuber initiation, water supply increases tuber size (Eldredge et al 1996;Shock et al 1998). The present results were in accordance with Sharafzadeh et al (2011) who found that under a sufficient water supply, the frequency of undersized tubers decreased and the frequency of marketable tubers increased.…”

This study assessed effects of irrigation water regimes and humic acid (HA) application on vegetative growth, yield, tuber quality and water use efficiency (WUE) of potato. Five irrigation treatments were applied at three developmental stages; (WR1) control (100 % crop evapotranspiration, 100 % ETc) at all plant growth, (WR2) 75 % ETc at all stages, (WR3) 75 % ETc at stage S1 (vegetative growth), (WR4) 75 % ETc at stage S2 (tuber initiation), and (WR5) 75 % ETc at stage S3 (tuber bulking). HA was applied at a rate of 1.5 g L −1 30 day after seed pieces planting. Plants experiencing water stress at S1 were shorter with fewer branches and lower fresh and dry vine weights. Water stress imposed at S2 significantly reduced tuber number, size, and yield. HA application increased vegetative growth, tuber weight, yield, WUE, and tuber quality (specific gravity and starch content). Thus, applying 1.5 g L −1 HA during vegetative growth and a 75 % ET water regime at S3 can increase potato production and tuber quality while reducing water use.Resumen En este estudio se evaluaron los efectos de los regímenes de agua de riego y la aplicación del ácido húmico (HA) en el crecimiento de la planta, rendimiento, calidad de tubérculo y la eficiencia del uso del agua (WUE) de la papa. Se aplicaron cinco tratamientos de riego en tres estados de desarrollo; (WR1) testigo (100 % evapotranspiración del cultivo, 100 % ETc) a todo el crecimiento vegetativo, (WR2) 75 % ETc en todas las etapas, (WR3) 75 % ETc en la etapa S1 (crecimiento vegetativo), (WR4) 75 % ETc en la etapa S2 (iniciación de tubérculo), y (WR5) 75 % ETc en la etapa S3 (llenado de tubérculo). Se aplicó HA a un nivel de 1.5 g*L-1 30 días después de la siembra de las unidades de semilla. Las plantas que experimentaron agobio hídrico en S1 fueron más cortas con menos ramas y pesos más bajos fresco y seco del follaje. El agobio hídrico impuesto en S2 redujo significativamente el número de tubérculos, el tamaño y el rendimiento. La aplicación de HA aumentó el crecimiento vegetativo, el peso de tubérculo, el rendimiento, WUE, y la calidad del tubérculo (gravedad específica y contenido de almidón). De aquí que la aplicación de 1.5 g*L-1 de HA durante el crecimiento vegetativo y un régimen de agua de 75 % de ET en S3 puede aumentar la producción de papa y la calidad del tubérculo mientras se reduce el uso del agua.
