“…Yield was higher and quality was better in Pyrgetos, a site with favourable soil and climatic conditions for sugar beet growth. On the clayey soils of Amfithea, sugar beet growth and yield are restricted by mechanical impedance and osmotic stress (Jaggard 1977, Katerji et al 1997). Limited precipitation, high temperatures and increased soil Na concentration impose a combination of stresses that is considered as drought stress (Munns 2002).…”

Selective absorption (SA) of K over Na (i.e. the preferential absorption of K over Na) has been proposed as a Na tolerance mechanism but genotypic variation for this trait has not been assessed with sugar beet in the field. Thus, the aim of this study was to explore the variation of SA in 14 sugar beet cultivars and to relate SA with yield and root quality in two sites of central Greece (Amfithea and Pyrgetos). Genotypic variation for SA was significant and the SA values were higher in Pyrgetos, the site with the lower soil K and Na concentrations. In Pyrgetos, a favourable environment for sugar beet growth, cultivars yielded more and root quality was better. In that site, a negative relationship between SA and yield (fresh root weight, sugar yield) was found indicating that strong Na exclusion from root is a disadvantage for high yielding. Negative SA–yield relationships were evident in Amfithea when five cultivars with very low SA values (<1.00) were excluded from the analysis. Combined all the cultivars, curvilinear functions were the best‐fitted curves for the SA–yield relationships. In Amfithea, where sugar beets had lower water content in root (WCR), a significant, positive correlation between SA and % sucrose content in fresh root weight was found. This finding was ascribed to the dilution of sucrose in roots due to the increased WCR as a result of the increased root Na concentration. In both sites, SA was positively related with root K concentration and negatively with Na concentration. The positive correlations between SA and root α‐amino N concentration indicated that sugar beet N nutrition could be affected by the genotypic ability to exclude Na from the root.

“…Sugar beet is precision‐drilled in March or April, when the soil is dry enough to be in good workable condition and the topsoil is not compacted by traffic during soil preparation and sowing (which would limit root growth) (Jaggard 1977, Maidl et al. 1982).…”

The environmental situation and current yield performance of sugar beet production in Germany are described and compared to those in other European regions. A continuous increase in yield performance and enhanced technical quality have been achieved through progress in breeding and improvements in crop management systems. This rise in yield potential has been brought about not by increased production intensity, but by better use of natural resources and production factors. In Germany, legislation rules many environmental aspects of agricultural plant production, and special laws are in force concerning fertilizer use, soil protection, and pesticide use. In sugar beet, nitrogen fertilizer use has decreased greatly and may be reduced further in some regions. A further reduction of potassium and phosphorus fertilizer use does not seem to be appropriate. Conservation tillage contributes to soil protection and is already performed on > 100 000 ha of land growing sugar beet. Strategies of integrated production aim to reduce pesticide use to the bare minimum. Integrated pest management is effective to control insects, nematodes and leaf spot diseases. Pesticide use in sugar beet is dominated by herbicide application. The most promising strategy to reduce the amount of active ingredient seems to be the growing of genetically modified herbicide‐tolerant varieties. Possible directions for future research are discussed, and the prospects for sustainable development, in terms of economic, ecological and social factors, are considered.
