“…Various formulae have been developed to assess root quality for processing (Table 1; for overview see van der Poel et al 1998;Burba and Harling 2003a, b, c;Dutton and Huijbregts 2006;Hoffmann 2006). They all include the concentrations of potassium, sodium, and amino N as representative for the so-called ''harmful'' nitrogen (total soluble N).…”

“…Therefore, it was recommended that beet at harvest should be topped below the level of the lowest leaf scars and to remove the crown and all green leaf material. It can be expected that the delivery of roots with crowns would lengthen the processing campaign because it can increase the amount of material delivered to the factory, and increases the costs for processing (Dutton and Huijbregts 2006).…”

The composition of the sugar beet root affects the recovery of crystalline sugar in the factory considerably. K, Na and amino N are melassigenic and are, therefore, always considered in the assessment of root quality for variety approval, and in some countries also for payment. The development of root quality during the season and the impact of variety, root rots, drought stress, N fertilizer application, defoliation/topping and storage are discussed. A further increase of the sugar concentration in varieties may be restricted by cell turgor and can probably only be achieved with a simultaneous decrease of the concentration of non-sugars. Future needs of the processing industry could change the criteria for quality assessment. It is observed that the alkalinity reserve (ion balance) of the juices gets lower so that soda has to be added. Moreover, long-term storage and the infestation with root rots result in a marked increase of the invert sugar concentration with detrimental consequences for processing. Therefore, quality assessment would probably be improved by considering alkalinity and invert sugar concentration. For the use of sugar beet for biofuel production, the sugar concentration (ethanol) or the organic dry matter (methane) of the roots are important quality criteria.

“…Many impurities are removed in a carbonation process where milk of lime [Ca(OH) 2 ] and carbon dioxide (CO 2 ) are mixed with the raw juice, forming calcium carbonate (CaCO 3 ) (USEPA 1997). The CaCO 3 occludes many impurities in the raw juice and precipitates out of solution (Dutton and Huijbregts 2006). The precipitated material is filtered out of the juice, and the purified juice is further processed into crystal sugar and molasses.…”

Factory lime generated during sugar beet processing contains phosphorus (P). Factory lime collected from seven sugar beet factories in North Dakota and Minnesota had P concentrations ranging from 3470 to 7043 mg P kg 21 . Soil collected from two field trials one and two growing seasons after factory lime application was analyzed for pH changes and soil-test P (STP). At one site, soil pH increased after both growing seasons, as did STP, indicating a continued release of P as the factory lime dissolved and reacted with the soil. At the second site, increased soil pH and STP were evident after one growing season, but a few months later the pH had no further change and STP decreased. The data suggest factory lime has the potential to supply P to a growing crop, but actual proportion of P available from the factory lime could not be quantified from these experiments.

Dynamics of spread of the most destructive sugar beet foliar diseases cercospora (Cercospora beticola Sacc.) and ramularia (Ramularia beticola Fautrey & F.Lamb.) leaf spot and efficacy of six fungicides used for their control were investigated at Rumokai Research Station of Lithuanian Research Centre for Agriculture and Forestry during 2011-2012. The crop was sprayed with fungicides once after the first symptoms of foliar diseases had been spotted. In the experimental years, cercospora leaf spot started to spread in the sugar beet crops on the 31 st of July -3 rd of August. During the 1 st assessment the disease incidence was 4.3-19.2% and the disease severity was 0.01-0.08%. Further progress of cercospora leaf spot was influenced by the weather conditions: with the weather being wet and warm the disease development was rapid and 10-11 weeks after the 1 st assessment the disease incidence reached 90.0-98.3%, and the disease severity was 10.98-11.91%. Ramularia leaf spot started to spread at the same time as cercospora leaf spot; however, its severity was lower. The progress of ramularia leaf spot was weaker than that of cercospora leaf spot and before harvesting ramularia leaf spot severity reached 1.75-1.79%. The highest efficacy against both diseases was exhibited by the fungicides containing epoxiconazole -Maredo, Opera N, Tango super.
