Sugar beet (Beta vulgaris L.) storage quality in large outdoor piles is impacted by pile management but not by nitrogen fertilizer or cultivar

Abstract

beet (Beta vulgaris L.) storage quality in large outdoor piles is impacted by pile management but not by nitrogen fertilizer or cultivar. Can. J. Plant Sci. 92: xxxÁxxx. Even though storage results in lower sucrose recovery from sugar beets, physical constraints dictate that a significant proportion of the sugar beet crop can be stored up to 120 d before processing. From 2006From to 2010 (1 ), sugar beet cultivar, and pile management method were independently evaluated to determine their effects on sugar beet storability in large outdoor piles. At harvest, five representative sugar beet samples from the N and cultivar field trials were placed in a large outdoor storage pile. Sugar beet quality assessments were taken at harvest and three times over the storage season. On the last retrieval date only, sugar beet samples were retrieved from piles managed via the length-vs. end-removal method. Although there were differences among N treatments and cultivars in sugar beet quality at harvest, there were no storage date by N treatment or storage date by cultivar interactions for any parameters measured indicating that N fertilization or cultivar did not influence the ability to maintain sugar beet quality in large outdoor piles. The lengthremoval method of pile management had better quality sugar beets compared with the standard end-removal method. Hence, sugar beet producers do not need to modify production practices to optimize storability, but sugar beet processors can improve sucrose recovery by removing sugar beets lengthwise along both sides of large piles as opposed to the standard end-removal method.Key words: Sucrose, pile removal, ammonium nitrogen fertilizer, variety, EuroMaus Van Eerd, L.

La qualite´de la betterave sucrie`re (Beta vulgaris L.) durant le stockage exte´rieur en tas importants est affecte´e par la me´thode de gestion des stocks, mais pas par l'usage d'engrais azote´s ni le cultivar. Can. J. Plant Sci. 92: xxxÁxxx. Bien que le stockage re´duise la quantite´de sucrose extraite de la betterave sucrie`re, les contraintes physiques ne´cessite l'entreposage d'une part importante de la re´colte avant transformation pendant un maximum de 120 jours. De 2006 a`2010, les auteurs ont e´value´se´pare´ment la fertilisation avec des engrais azote´s (0 a`220 kg de N par hectare), le cultivar et la me´thode de gestion des stocks en vue d'e´tablir l'incidence de ces parame`tres sur la capacite´d'entreposage des betteraves sucrie`res en gros tas exte´rieurs. À la re´colte, ils ont pre´leve´cinq e´chantillons repre´sentatifs de betteraves dans les parcelles soumises aux essais de fertilisation N et de cultivar, et les ont de´pose´s dans des amas importants stocke´s a`l'exte´rieur. Ils ont ensuite e´value´la qualite´des betteraves a`la re´colte et a`trois autres moments, durant l'entreposage.

Interactive Effects of Gibberellic Acid and Nitrogen Fertilization on the Growth, Yield, and Quality of Sugar Beet

“…A moderate supply of nitrogen fertilizer is an essential limiting factor for optimum yield, but the excess in nitrogen fertilizer amounts may result in an increase in root yield with lower sucrose content and juice purity [4][5][6][7]. Over fertilizing sugar beet with more nitrogen than needed for maximum sucrose production led to decreased sucrose yield [8,9]. With increasing nitrogen supply, sugar concentration decreased, while root yield, sugar yield, and white sugar yield increased and reached maximum values when sugar beet was fertilized at 159, 136, and 129 kg N/ha, respectively [42].…”

“…Many studies have been conducted where it was concluded that fertilizing sugar beet with too little nitrogen resulted in the reduction of root tonnage and, conversely, the application of too much resulted in reduced sucrose concentrations and purity percentage [4][5][6][7]. Although deficient nitrogen content in the soil can reduce sugar beet root yield, excess amounts of N can decrease sucrose content while lowering sucrose recovery due to higher nitrate impurities [8,9]. In England, sugar beets are fertilized using 100-110 kg N/ha as an equilibrating rate between fertilizer prices and beet value [10].…”

The Influence of the Process of Sugar Beet Storage on Its Biochemical Methane Potential

“…This is an innovative, not yet described in the literature, way of storing sugar beet as a potential biomaterial for energy production, which does not require building storage lagoons, does not take up the land that could be otherwise used for cultivation and thus reduces investment costs. However, storing sugar beet pulp in open storage lagoons for energy purposes is commonly used, for instance, by German agricultural biogas plants [34,35]. Nonetheless, such a method has its drawbacks, the chief one being the loss of organic and mineral matter from the stored biomass, as reported in the literature [28,36].…”

“…As the storage period was extended (by another 8, 16 and 32 weeks), the decomposition of the organic matter took place-both in the sugar beet stored in airtight conditions and in the pulp stored in an open-air container. After 8 and 16 weeks of storage, the biogas efficiency was increased: 139 35. mL•g −1 FM-H, 144.14 mL•g −1 FM-O, 147.58 H mL•g −1 FM-H and 148.22 mL•g −1 FM-O, respectively.…”

Influence of Harvest Timing, Fungicides, and Beet necrotic yellow vein virus on Sugar Beet Storage

“…However, given the significant losses currently suffered in storage in Idaho, host resistance and cultivar selection alone are not enough to deal with storage problems (9,12,26,46). Currently, physical control practices such as tarping, ventilation, and stripping the outer meter of sugar beet roots from the pile surface are utilized to reduce storage losses (6,37,38,57). Although these physical methods reduce sucrose losses, additional control measures for storage such as chemical treatments have been investigated (1,12,23,31,32,61).…”
