“…Potassium influences the water content of the plasma volume, thus affecting the water content of fleshy storage tissues, like the tubers. Iritani and Weller (1978) reported that fertilizer rates influenced sugar accumulation in tuber. Elevated K concentrations in the tubers of above 2% dry weight (DW) can lead to above-normal water contents and lower contents of dry matter (Bergmann, 1992).…”

An experiment was conducted at Divyapuri of Nawalparasi district in the western Terai during winter season 2008/09. There were 16 treatments consisting of two mulch levels (mulched and no mulch) as main plot, two varieties (Kufri Chipsona-1 and Kufri Chipsona-2) as sub plot and four levels of potash (0, 50, 100 and 150 kg K 2 O /ha) as sub-sub plot arranged in split-split plot design with four replications to evaluate the effect of these treatments on tuber production and their effect on quality of potato chips. The result showed that plant height, number of shoot per plant, dry matter accumulation, number and weight of tuber per plant and tuber yield were significantly higher in Kufri Chipsona-2 than in Kufri Chipsona-1. Lower reducing sugar and browning percent of chips and higher dry matter content and chips recovery were also recorded in Kufri Chipsona-2 compared to Kufri Chipsona-1. Simple economic analysis on gross return, net return and B/C ratio were higher in Kufri Chipsona-2. However, increasing levels of potash from 0-150 kg K 2 O /ha increased the dry matter accumulation, LAI, number and weight of tuber per plant. The result also showed that as the level of potash increased there was a decrease level of reducing sugar and browning of chips as well. On the other hand, higher potash levels increased the percentage of fat content and recovery of chips. Also increase in potash levels resulted to increase in gross return, net return, and B/C ratio. There was no effect of mulching levels on tuber yield and quality of chips recovery. Of the two varieties, Kufri Chipsona-2 with 100 kg K 2 O/ha was found suitable for tuber production and recovery of chips quality.

“…Fertilizer applications can impact the processing quality of harvested tubers (Iritani and Weller 1978). These studies indicate tubers harvested from the control treatment showed a significantly higher glucose concentration at harvest compared to the other treatments in 2008 (Table 5).…”

“…A similar trend (p<0.10) was observed the following year in 2009 of higher glucose concentration in the control tubers compared to the manure, fertilizer and compost treatments. Higher glucose levels can often be seen at harvest with overly mature potatoes (Iritani and Weller 1978). Higher glucose levels may indicate a difference in maturity between treatments and lower processing quality with inadequately fertilized control treatment.…”

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...

“…By comparison, the surveyed sprinkler irrigators applied 30 to 40 mm per irrigation which would produce much smaller deep percolation losses. The longer furrow irrigation intervals and probable nitrogen deficiencies caused by large amounts of deep percolation could contribute to the higher incidence of dark end tubers produced under furrow irrigation (9). It is surprising that this large difference in water application did not significantly affect yields and visual quality.…”

“…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. CompendioUna encuesta de productores en el Valle del Tesoro (Treasure Valley) del oeste de Idaho y este de Oregon indicO que la papa Russet Burbank tendia a producir tuberculos de mejor calidad bajo irrigaciOn por aspersi6n que bajo irrigaciem por surco. Se llevaron a cabo estudios de irrigaciOn en parcelas durante tres alms y dos lugares para determinar si estas diferencias eran el resultado de practices de manejo comunmente utilizadas o inherentes al metodo de irrigaci6n. Con un buen manejo del agua, el metodo de irrigaciem no afectO los rendimientos, pero la irrigaciOn por aspersion produjo tuberculos con una calidad visual ligeramente superior y una muy menor incidencia de azUcares terminales. 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-
