Storage Methods

Different seed storage methods, varying in storage temperature, moisture and/or oxygen content, were applied to commercial sugar beet seed lots from four breeding companies. After storage for 10–11 months, germination of the seed was tested in the laboratory (cold test, 10°C). In addition, the contents of active ingredients (fungicides and insecticide) were analyzed and compared with the initial contents before storage. Based on these results, a selection of the most promising storage methods was made to test plant emergence in a field experiment. This research was performed in 2015/16 and in 2016/17. In both years, two storage treatments outperformed the others: these were storage in a closed jar with the addition of moisture absorber (i.e. silica gel) at room temperature and storage at –18°C in a closed plastic bag. Using these two storage methods, seed vigour and contents of active ingredients were comparable to those in seed that had not been stored for one year. Based on the results from this study, the advice to growers for a successful storage of residual sugar beet seed was adjusted in 2017, after including some practical guidelines and considerations.

Summary. The vigour of Welsh onion (Allium fistulosum L.) seeds with low moisture content was determined after exposure to different storage temperatures and container types. As the storage period was prolonged, the effects of storage temperature and container type on seed vigour became more pronounced. Storage temperature had a greater effect on seed vigour than container types, and the effect of the latter was subject to the storage temperature. When the seeds were stored in the same type of container, several indices of the seed vigour declined as the storage temperature increased. A highly significant positive correlation was evident between dehydrogenase activity and the percentage germination of the seed. Improving storage conditions could prolong seed longevity. If the seeds, in which the moisture content has been reduced to less than 6%, are stored airtight, the percentage germination will be about 85% after storage for 2 years at room temperature or after 3-year storage at 6°C. If the seeds are stored at –6°C, the percentage germination will range from 86 to 91% after 3-year storage, regardless of the storage container types in this study. These data are very important for the seed storage and germplasm conservation of Welsh onion.

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.

First Time

In January 2021 the UK government granted an application for authorisation to use thiamethoxam, a neonicotinoid pesticide, to protect commercial sugar beet crops from attack by viruses transmitted by aphids. This was the first time such an authorisation had been granted in the United Kingdom (UK) and there were concerns that it signalled a weakening of environmental standards now that the UK was no longer part of the European Union. In fact, similar authorisations had been granted by several European Member States in the last 2 years, despite the ban on the use of neonicotinoids introduced in 2018. Nevertheless, the reasons for granting the authorisation do suggest that the balance between adopting a precautionary approach to environmental protection and taking emergency action to protect economic interests may have shifted. It was acknowledged that the proposed mitigation to safeguard bees and other wildlife was not entirely satisfactory. In the end, due to unforeseen weather conditions it meant that the pesticide is not necessary, which in itself demonstrates that short-term emergency measures are unsuitable for dealing with the problem. If the sugar beet industry is to continue to prosper in the UK, it will need to be managed in a way that provides resistance to virus infection without the use of controversial chemicals.

AbstractSeeds of four African tree species from the Sahelian zone (Boscia senegalensis) and the Sudanian zone (Butyrospermum parkii, Cordyla pinnata and Saba senegalensis) lose viability after moisture contents drop below 22 and 30%, depending on the species. Seed longevity in wet and airtight storage does not exceed a few months. Temperatures close to zero elicit symptoms of chilling injury leading to rapid seed death. The optimum storage temperature is 15°C. These results allow the four species to be classified as recalcitrant seed species. Boscia senegalensis is therefore an exception in arid zones where most species have orthodox seeds.

Seeds of Garcinia talbotii remained viable hardly for two weeks in open room conditions. As part of ex-situ conservation of Garcinia talbotii, seeds longevity was studied since seeds are the main propagule. For this, the relationship of seed viability with respect to different moisture content and storage temperature were analyzed. Seed storage behaviour is also investigated. Being recalcitrant, seeds are desiccation sensitive as well as chilling sensitive. During hermetic storage of seeds at 300C /70 % RH seeds retained viability about 6 months.

SummaryTwenty experiments between 1970 and 1974 tested the effect of spring applications of all combinations of five amounts of potassium (0–333 kg K/ha) and two amounts of sodium (0, 150 kg Na/ha) on sugar-beet yield, profitability and the amount of K and Na in the crop in mid-summer. The experiments were in commercial sugar-beet crops where soils contained little exchangeable potassium, most having less than 100 mg K/l in top soil. On average, sugar yield was greatest when 150 kg Na/ha plus 167 kg K was used, the fertilizer increasing yield by 0·71 t/ha. Response to this combination of K and Na fertilizers was 1·45, 0·57 and 0·22 t sugar/ha when the soil contained less than 60, 61–120 and more than 120 mg K/l respectively.From results of earlier experiments, it was thought that response to even a large amount of K without Na would be less than to Na without K because usually there is insufficient rainfall in the spring for maximum response to K. In fact, 333 kg K/ha increased yield by about the same amount as Na, probably because a large proportion of these experiments were made in wetter-than-average springs.The concentration of K in dried tops and roots in mid-summer increased linearly with soils containing from 40 to 120 mg K/l but when there was more K in the soil the concentration of K in the plants did not increase further. By contrast, the concentration of Na in plants did not reach a similar plateau. Whole plants in mid-summer contained between 128 and 251 kg K/ha and 42–102 kg Na/ha, depending on the fertilizer treatment. Recovery of applied K varied from 90% when small amounts were used on fields containing least K to about 20% when large amounts were given on fields containing moderate amounts. Recovery of Na varied from about 50 to 23%.The comparison of the financial return from using K alone or K plus Na showed that Na was essential for maximum profit. On average, the most profitable dressing of K gave a return of £14/ha whereas K plus Na gave up to £46/ha. On fields with least K, the corresponding results were £50 and £115/ha respectively. In relation to soil K, the most profitable application was 150 kg Na/ha plus about 150 kg K/ha on soils with 60 mg K/l or less, and 150 kg Na/ha plus about 75 kg K/ha on most other soils.

Storage Methods

Two experiments were conducted to assess the effects of storage conditions on the quality of large round bales (LRB). Samples were taken at 75-d intervals from LRB stored inside, outside single bales covered with a 15-mm black polyethylene plastic bag, outside uncovered as single bales, outside uncovered in a single row and outside uncovered in a double stacked row. Bales were sampled at depths of 0–15, 15–30 and 30–45 cm. Time, storage and depth factors had an influence on the chemical components of the LRB except for protein. Weathering had the most effect after 150 d of storage and with LRB stored uncovered and in the top 15-cm layer. Significant (P < 0.05) interactions in in vitro dry matter digestibilities were found for storage time × depth of sample, storage time × storage methods and for depth of sample × storage methods. Under the conditions of our experiments, weathering damages were limited to the superficial layer of LRB left uncovered. Key words: Large round bales, weathering, storage, moisture

The Impact

A five-year experiment was carried out in the Nyírség on its characteristic soil type, brown forest soil to investigate the impact of three types of potassium fertilizers (potassium chloride, potassium sulfate and Patentkali) in three different dosages (80, 160, 240 kg/ha K20), under non-irrigated conditions applying the same dosages of N, P in all treatments (the applied amount was different between years) in 10 treatments including the control on 50 m2-parcels with 3 or 4 replicates. The test plant was cultivar Desiree, Kondor, Agria and Pannonia in 1998 and 2000, 2001, 2002 and 2003, respectively. The obtained yields were analyzed by an analysis of variance. Based on the five-year results, the highest yields on the acidic sandy and sandy loam soils were obtained in the treatments with 530-800 kg/ha Patentkali containing 30% of K and 10% of magnesium active ingredients in addition to the same amounts of N and P applications. The dosage of 530 kg/ha Patentkali contains 160 kg/ha K+ 53 kg/ha Mg active ingredients, while the dosage of 800 kg/ha Patentkali contains 240 kg/ha K+ 80 kg/ha Mg active ingredients. It can be concluded that the potassium chloride fertilizer (KCI) was the least effective as regards yields and Patentkali proved to be the most effective fertilizer, it had higher yields than even those of potassium sulfate, the difference in the 160 kg/ha treatments was 17.7%, which was a significant difference. Based on the results of the multi-year experiment, we recommend to apply 530 kg/ha Patentkali fertilizer (160 kg/ha K+ 53 kg/ha Mg active ingredients) for the fertilization in potato under non-irrigated conditions on the acidic sandy and sandy loam forest soils of the Nyírség, which proved to be the most effective treatment and with which we could obtain 30 t/ha yield in the average of the years (with the simultaneous application of N and P).
