Harvest quality of sugar beet varies according to soil conditions, harvester type and setting, and variety, too. Harvest quality may affect storage losses, in particular when injuries occur. To determine the harvest quality of commercial sugar beet and to quantify resulting storage losses, 92 commercial sugar beet clamps were sampled across Germany and information about harvest conditions were gathered. At IfZ, soil tare, leaf residues, topping diameter, root tip breakage and surface damage of the beets were determined. The beets were stored in 6 replicates in a climate container at 9°C for 10 weeks. The results demonstrate a rather good harvesting quality of sugar beet in Germany. Soil moisture at harvest did not affect harvest quality and storage losses. Very light, but also heavier soils lead to inferior harvest quality (soil tare, root tip breakage, damage) and slightly higher storage losses compared to the typical loam soils. Significant differences occurred between the three harvester types (companies). In general, high root tip breakage and severe surface damage of the beet was related to a high infestation with mould and rots, high invert sugar contents after storage and high sugar losses. Out of the five most planted varieties, in particular one turned out to be very susceptible to damage, resulting in high storage losses. The factor analysis suggests that the effect of harvester / harvester setting and of variety is more important for harvest quality and storage losses of sugar beet than soil conditions at harvest. Therefore, attention should be paid to optimize these conditions.

The Impact

Damage resulting from harvest operations increases the storage losses of sugar beet. Because of different equipment, the kind and extent of damage may differ between harvesting systems. The objective of the study was to analyze (I) the impact of different harvesting systems and cleaning intensities on damages of sugar beet, and furthermore, (II) the effect of these damages on storage losses. In 2015 and 2016 at four sites, two sugar beet varieties were harvested with two six-row harvesters (axial rollers versus turbines for cleaning) using three cleaning intensities with three replicates in tracks of 200m length. Roots were stored in a climate container at 9°C for 5 and 12 weeks. The results show that the diameter of root tip breakage and surface damage increased with cleaning intensity. Marked differences occurred among varieties and sites. The factor analysis indicates that the extent of damage (root tip breakage, surface damage) had a considerable impact on the infestation with mold and rots, the accumulation of invert sugar and sugar losses after storage. However, the higher root tip breakage of beets harvested by harvester2 was accompanied by lower sugar losses than in harvester1 after 12weeks storage, in particular with the aggressive cleaning intensity. The marked impact of the cleaning intensity emphasizes the importance of the operator and of the optimal setting of the harvester for a good harvest quality and thus storability of sugar beet.

Sugar Loss

Good storability of sugar beet is of increasing importance, not only to reduce sugar losses, but also with regard to maintaining the processing quality. Genotypic differences are found in storage losses. However, it is not clear to which extent damage may contribute to the genotypic response. The aim of the study was to quantify the effect of root tip breakage on storage losses of different genotypes. For that purpose, in 2012 and 2013, six sugar beet genotypes were grown in field trials at two locations. After lifting roots were damaged with a cleaning device. They were stored for 8 and 12 weeks, either under controlled conditions in a climate container at constant 8°C, or under ambient temperature in an outdoor clamp. The close correlation underlines that storage losses under controlled conditions (constant temperature) can well be transferred to conditions in practice with fluctuating temperature. The strongest impact on invert sugar accumulation and sugar loss after storage resulted from storage time, followed by damage and growing environment (year × growing site). Cleaning reduced soil tare but increased root tip breakage, in particular for genotypes with low marc content. During storage, pathogen infestation and invert sugar content of the genotypes increased with root tip breakage, but the level differed between growing environments. Sugar loss was closely related to invert sugar accumulation for all treatments, genotypes and environments. Hence, it can be concluded that root tip breakage contributes considerably to storage losses of sugar beet genotypes, and evidently genotypes show a different susceptibility to root tip breakage which is related to their marc content. For long-term storage it is therefore of particular importance to avoid damage during the harvest operations and furthermore, to have genotypes with high storability and low susceptibility to damage.

There is some evidence that sugar beet root tissue strength affects damage susceptibility and storage losses. This study aimed at analyzing the effect of N application and of irrigation on tissue strength of sugar beet varieties, on root composition, and on root tip breakage and storage losses. For this purpose, field trials in six replicates with three sugar beet varieties were carried out with three N doses in The Netherlands and Belgium in 2018 and 2019, alternatively with three irrigation treatments in Sweden in 2018 and 2019. Results show a low impact of N application and irrigation on puncture resistance, tissue firmness and compressive strength of the roots, while varieties differed always stronger and significantly. Cell wall composition (pectin, hemicellulose, cellulose, lignin) did not differ markedly in roots from different environments (sites, years) and varieties, giving no explanation for differences in tissue strength. However, the percentage of cell wall material (AIR, marc) and of dry matter were higher in roots with higher tissue strength. Root tip breakage and sugar losses during storage tended to be lower when root compressive strength of varieties was higher. Hence, root tissue strength could serve as an indirect selection criterion for reduced damage susceptibility and improved storability of sugar beet varieties.

HighlightsTime to bind a round bale was longest for twine (56 s) compared to B-Wrap® (28 s) and net wrap (18 s).Alfalfa cultivar had minimal effects on changes in dry matter and forage quality of round bales stored outdoors.Dry matter losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM in outdoor storage.Deleterious changes in forage quality were generally observed after =180 days of outdoor storage. Abstract. Large round bales are commonly fed to livestock; however, it has been well documented that outdoor storage can negatively impact dry matter (DM) and forage quality. To reduce storage losses and improve feeding value, new wrap types and alfalfa cultivars have been developed; however, these options have not been extensively investigated. Therefore, the objectives of this research were to evaluate the time required to bind large round bales, determine changes in DM and forage quality, and examine the economics of reduced-lignin and conventional alfalfa hay bound in twine, net wrap, and B-Wrap® while in outdoor storage. Hay was baled into 24 large round bales; 12 bales each of reduced-lignin and conventional alfalfa. Within each cultivar, four replicates were bound with each wrap type. Using stopwatches, the time to bind each bale was recorded. At the time of harvest, and every 90±3 days for 365 days, individual bales were weighed and cored to determine changes in DM and forage quality. Significance was set at P = 0.05. Time to bind a bale was longest for twine, intermediate for B-Wrap®, and shortest for net wrap (P < 0.01). Alfalfa cultivar had minimal effects on the parameters measured; therefore, the interaction between wrap type and storage length was reported. After 365 days in outdoor storage, DM losses were 7% for twine bales, 5% for net wrap bales, while B-Wrap® bales maintained DM. Changes in forage quality were observed at =180 days of storage where nonstructural carbohydrates were decreased and insoluble fiber components were concentrated. B-Wrap® bales had a higher value compared to net wrap and twines bales at 180 and 270 days in storage. These results suggest that B-Wrap® was better able to shed precipitation which preserved forage quality and bale value compared to large round bales bound in net wrap and twine in long term, outdoor storage.

Abstract The objective of this study was to evaluate the effect of modified atmosphere (MA) and 1-methylcyclopropene (1-MCP) treatment on low storage temperature (1.5 °C) and 1-MCP treatment on high storage temperature (8.0 °C) on fruit quality of ‘Laetitia’ plums, mainly on internal browning. The treatments evaluated were 1.5 °C; 1-MCP (1.0 µL L-1) + 1.5 °C; MA + 1.5 °C; 1-MCP + MA + 1.5 °C; 8.0 °C; 1-MCP + 8.0 °C. Fruit were stored for 30 and 40 days, followed by three day of shelf life. For fruit stored at 1.5 °C, the treatment with 1-MCP associated to MA provided higher flesh firmness, less intense skin red color and reduced occurrence of internal browning in comparison to the fruit stored at 1.5 °C of the remaining treatments, for both periods of storage. In fruit not treated with 1-MCP and stored at 8.0 °C there was no occurrence of internal browning, despite of lower flesh firmness and more intense red color of the skin and flesh in comparison to the fruit stored at 1.5 °C. The treatment with 1-MCP in fruit stored at 8.0 °C delayed those changes of flesh firmness and red color of the skin and flesh assessed after 30 days of storage, followed by three days of shelf life. The MA, regardless of 1-MCP treatment, had fruit with higher production of acetaldehyde after 30 days of storage, and ethanol after 30 and 40 days of storage at 1.5 oC. In fruit stored at 1.5 °C without MA, the treatment with 1-MCP reduced the production of ethyl acetate, acetaldehyde and ethanol. Fruit stored at 8.0 °C, regardless of 1-MCP treatment, had the lowest production of acetaldehyde and ethanol.

Harvesting and cleaning of sugar beet lead to root damage, which increases storage losses due to wound healing and by causing entry points for pathogens. This study aimed at quantifying the effects of variety and site on the tissue strength of sugar beet roots, and moreover, to evaluate the impact of tissue strength on damage and storage losses. For this purpose, field trials with three varieties were carried out at six sites, three in Germany and the others in Belgium, the Netherlands and Sweden in 2018. Texture analysis and storage trials were conducted in Göttingen. Puncture and compression measurements revealed differences in tissue strength between varieties and sites. Drought stress during the vegetation period significantly reduced the tissue strength. Tissue strength of sugar beet roots turned out to be an environmental stable variety characteristic. It is not possible to draw conclusions from tissue strength to storage losses at a site, since many other factors, such as growing conditions, diseases and damage due to harvester settings have a strong impact. However, tissue strength might be an indicator for damage susceptibility and storage losses of sugar beet varieties.

And Storage

During storage, the invert sugar content of sugar beets increases with increasing storage period and storage temperature, thereby decreasing the processing quality of the beets substantially. Invert sugar results from the enzymatic degradation of sucrose to glucose and fructose. The current methods to determine invert sugar in sugar beets have a low sample frequency and are very expensive and are therefore not implemented in the routine analyses of sugar factories. The content of invert sugar could be calculated based on the glucose content. This requires a constant ratio of glucose to fructose in freshly harvested sugar beets as well as in sugar beets stored under different conditions. The objective of the present study was thus I) to analyse the glucose to fructose ratio of freshly harvested beets and of beets stored under different conditions, and II) to develop a formula to estimate the invert sugar content based on the glucose content of sugar beets. The ratio of glucose to fructose in freshly harvested beets and beets stored under different conditions was quite similar. A close linear relationship between glucose and invert sugar content in freshly harvested and stored beets was found. By using the regression function, the invert sugar content of an independent dataset was calculated based on the glucose content. The estimated invert sugar content was closely correlated with the invert sugar content measured by HPLC. The invert sugar content in freshly harvested and stored sugar beets can thus be calculated with the formula developed in this study. This would considerably improve the quality assessment of sugar beets once the new method to measure the glucose content becomes implemented in the routine analysis in sugar factories.

To reduce storage losses and improve resistance to rhizomania caused by Beet necrotic yellow vein virus (BNYVV), studies were initiated to establish a storage cultivar selection program. In 2006 and 2007, 30 or more commercial sugar beet (Beta vulgaris) cultivars were grown in soil naturally infested with BNYVV. At harvest, two root samples from each plot were collected and used to establish percent sugar. Additional samples were placed on top of an indoor pile (set point 1.7°C) and inside an outdoor pile in a randomized complete block design with four replications. After 142 and 159 days in indoor storage, sucrose reduction ranged from 13 to 90% in 2007 and 57 to 100% in 2008. Outdoor storage sucrose reduction ranged from 13 to 32% in 2007 and 28 to 60% in 2008. An average of 31 and 45% of the root surface was covered with fungal growth in 2007 and 2008, respectively. Cultivars that retained the most sucrose had resistance to BNYVV and the least fungal growth and weight loss. Indoor storage with BNYVV-infested roots allowed for the most consistent cultivar separation and will potentially lead to selection of cultivars for improved storability and rhizomania resistance.
