Effect of Sugar Beet Genotype, Planting and Harvesting Dates and Their Interaction on Sugar Yield

Abstract

Climate changes are affecting the plant production, including sugar beet growing especially in the southern and central parts of the Europe. Modifying the sowing and harvesting dates are one of the most often used adaptations in sugar beet cultivation. The aim of this study was to assess the interactions between planting date and sugar beet genotypes for different harvest dates with recommendation for duration of vegetation period for specific hybrids in order to achieve the best performance and to evaluate influence of climatic factors on sugar yield. Three-way analysis of variance and AMMI (Additive main effect and multiple interactions) analysis were performed to investigate interaction between main factors. Analysis of variance revealed that genotypes (G), planting date (PD), harvest date (HD) and interaction G × PD significantly affected sugar yield in 2016. In 2017 genotypes, planting date, harvest date and G x PD interaction significantly affected sugar yield on probability level of 1%, while PD × HD interaction had significant effect on probability level of 5%. Results of AMMI analysis enabled discrimination of genotypes with the highest level of stability in certain planting dates. Hybrids with combined yield and sugar content (NZ type) should have the advantage in earlier planting dates compared to of sugar beet hybrids with higher sugar content (Z type). However, in shortened vegetation period Z type hybrids are more stable and with better sugar yield results. Results of our study suggest that delaying the harvest date decreases differences between sugar yields obtained from hybrids sown in different planting dates. Major factors in the study affecting sugar yield were growing degree days, insolation and number of days from planting to harvest.

Assessment of Stability and Adaptation Patterns of White Sugar Yield from Sugar Beet Cultivars in Temperate Climate Environments

“…There is no biological reason for the division into these specific mega-environments. Similarly, as in the case of the sugar beet [28,29], the lack of justification for the division of locations into a mega-environment was observed in many other species of arable crops [30,31].…”

Mitigation of emerging implications of climate change on food production systems

“…The above-described strategies can be supplemented with others based on innovation in planting and harvesting genomics. Some American and European countries have already diversified livelihoods, harvested rainwater or used alternative livelihoods for fishing by developing change-resistant hybrids, as a mean to face climate change, especially among farmers in diverse tropical and subtropical areas all over the world (Curcic et al, 2018). This should generate new opportunities but also lead to limitations arising from various factors of not only environmental and technological character, but also of political and market factors (Schroth and Ruf, 2014;Debaeke et al, 2017).…”

From Emergence to Flowering: Four Beet (Beta vulgaris ssp.) Cultivars’ Phenological Response to Seed Priming

“…Each of these groups has a different usage in industry and consumption. In Europe, sugar beet is the main crop for sugar production [3,4]. Moreover, it provides clean energy through bioethanol and the production of hydrogen gas.…”
