Abstract

Field experiments were conducted at high- and low-S status sites in the 1998 and 1999 seasons to investigate the effect of sulphur application on the growth and metabolism of sugar beet. Application of sulphur (25 kg ha -1) resulted in a 25% increase in root yield together with significant increases in root and shoot dry matter accumulation at the low-S site only in the 1998 season. Beet quality was also increased through a reduction in α-amino N concentration. Crop S uptake was shown to be as much as 35 kg S ha-1 per year but with most S being returned to the soil removal of S is likely to be <15 kg ha-1 per year. The use of diagnostic plant indicators to predict sulphur deficiency in this crop was limited by the potential of the crop to access subsoil S through an extensive rooting depth. Application of sulphur to high-S status sites had no effect on the growth or metabolism of sugar beet. © 2003 Elsevier Science B.V. All rights reserved.
