“…These tubers were analyzed for sugar concentration after 15 weeks in 2003 and 2004 and after 25 weeks in 2005 and 2006. Glucose and sucrose concentrations were determined using procedures described by Sowokinos et al (2000). For round white cultivars, 200 g of tuber tissue was sampled from six tubers for each plot and juiced with a model 6001 Acme Supreme Juicerator in 50 mM sodium phosphate buffer, pH 7.2.…”

Maleic hydrazide has been reported to increase the proportion of US #1 (> 113 g) potatoes and lower the concentration of reducing sugars of potato tubers in storage, thus improving fry color. We tested the effect of three different application timings of maleic hydrazide on total and US #1 yields, average tuber weight, "b" and cull yields, and tuber glucose and sucrose concentrations at harvest and after storage. The cultivars evaluated included two round white potatoes, Atlantic and White Pearl, and one russeted cultivar, Freedom Russet. Maleic hydrazide had no effect on total yield or US #1 yield for either round white cultivar, but increased both total and US #1 yield for Freedom Russet. In addition, maleic hydrazide reduced average tuber weight for Atlantic. These yield effects were dependent on application timing. Maleic hydrazide had no effect on yield of cull tubers. Maleic hydrazide did not lower glucose or sucrose concentrations at harvest or during storage for any of the cultivars tested, and increased Atlantic tuber glucose concentration at harvest. In summary, the effect of maleic hydrazide on yield was cultivar-dependent and maleic hydrazide did not reduce tuber glucose concentrations for any cultivar tested.Resumen Se ha reportado que la hidrazida maleica incrementa la porción de papa US # 1 (> 113 g) y baja la concentración de azúcares reductores en los tubérculos almacenados, mejorando así el color de la fritura. Nosotros probamos el efecto de tres diferentes momentos de aplicación de hidrazida maleica sobre el rendimiento total de US # 1, peso promedio de tubérculo, rendimiento de tubérculos "b" y de desecho, y concentración de glucosa y sacarosa en el tubérculo a la cosecha y después del almacenamiento. Los cultivares evaluados incluyeron dos de papa redonda blanca: Atlantic y White Pearl y un cultivar rugoso el Freedom Russet. La hidrazida maleica no tuvo efecto sobre el rendimiento total de US # 1 de ninguno de los cultivares redondos blancos, pero incrementó tanto el rendimiento total y de US # 1 de Freedom Russet. Además, la hidrazida maleica redujo el peso promedio del tubérculo de Atlantic. Estos efectos sobre el rendimiento dependieron del momento de aplicación. La hidrazida maleica no tuvo efecto sobre el rendimiento de tubérculos de desecho, tampoco bajó las concentraciones de glucosa y sacarosa a la cosecha o durante el almacenamiento en ninguno de los cultivares probados e incrementó la concentración de glucosa en los tubérculos de Atlantic al momento de la cosecha. En resumen, el efecto de la hidrazida meleica sobre el rendimiento dependió del cultivar y no redujo las concentraciones de glucosa de ningún cultivar probado.

“…Cold-induced sweetening (CIS), a result of the accumulation of reducing sugars in cold-stored potato tubers, has been mainly studied for its relation to potato processing (Dale and Bradshaw 2003;Sowokinos 2001). Another form of reducing-sugar accumulation is sugar-end defect formation, which is typically associated with exposure of the plant to high temperatures during tuber initiation and bulking (Sowokinos et al 2000;Kincaid et al 1993). This form of reducing-sugar accumulation does not require low-temperature storage of tubers and cannot be removed by reconditioning at relatively warm temperatures, as can CIS (reviewed by Thompson et al 2008).…”

“…Tuber processing quality was assessed by evaluating glucose and sucrose content and fry color and quality. Sucrose and glucose concentrations for the above treatments were determined from a ten-tuber sample after harvest using the method of Sowokinos et al (2000) with modifications. Tubers were cut using a Keen Kut Shoe Stringer French fry cutter.…”

Residual Effects of Fresh and Composted Dairy Manure Applications on Potato Production

et al. 2011

Potato growers in Idaho and other dairy producing regions often grow potatoes on fields that have had a history of fresh and composted manure applications. Growers remain uncertain of the impacts that previous manure applications will have on tuber yield and quality, as well as diseases, physiological disorders, and contamination by human pathogenic bacteria such as E. coli. The focus of this study was to determine the long term effects of manure, compost, and chemical phosphorus (P) fertilizer applications on tuber yields, tuber quality, nutrient uptake, tuber disorders and diseases, and soil nutrient concentrations. Russet Burbank potatoes were grown in 2008 and 2009 on plots that had received dairy manure, dairy compost, P fertilizer, or no P source (control) at the same target P rate in 2003, 2004, and 2005. Compared with the P fertilizer treatment, applications of manure and/or compost significantly increased total yields, soil potassium (K), soil nitrate (NO 3 -N), early season petiole P, and late season petiole K in at least one year of the two-year study. There were no significant differences between P fertilizer, manure, and compost treatments on soil test P, late season petiole P, early season petiole K, E. coli populations on tuber surfaces, common tuber diseases and disorders, and tuber quality. Based on our findings, tuber yields significantly increased three years after applications of fresh and composted dairy manure, while tuber diseases, disorders, and quality were not affected.Resumen Los productores de papa en Idaho y de otras regiones lecheras a menudo cultivan sus papas en campos que han tenido una historia de aplicaciones de estiércol fresco y compostado. Los productores permanecen inciertos de los impactos que las aplicaciones previas de estiércol tendrán en rendimiento y calidad de tubérculo, así como de enfermedades, desórdenes fisiológicos y contaminación por bacterias patogénicas para humanos tales como E. coli. El enfoque de este estudio fue determinar los efectos a largo plazo de las aplicaciones de estiércol, la composta y el fertilizante químico de fosforo (P) en el rendimiento y calidad de tubérculo, absorción de nutrientes, desórdenes y enfermedades del tubérculo y concentración de nutrientes en el suelo. Se cultivaron papas Russet Burbank en 2008 y 2009 en lotes que habían recibido estiércol, composta, fertilizante fosforado (P) o sin fuente de P (testigo) al mismo objetivo de nivel de P en 2003, 2004 y 2005. Al comparar con los tratamientos de fertilizante de P, las aplicaciones de estiércol y/o composta aumentaron significativamente los rendimientos totales, el potasio (K) y el nitrato (NO 3 -N) del suelo, el P temprano del pétalo y el K tardío del pétalo en por lo menos un año de los dos del estudio. No hubo diferencias significativas entre los tratamientos del P del fertilizante, estiércol y composta en pruebas de P del suelo, P tardío del pétalo, y K temprano del pétalo, poblaciones de E. coli en las superficies del tubérculo, enfermedades y desórdenes comunes y ca...
