Abstract
This work aimed to establish whether a change from triploid to diploid cultivars would require any adjustment of the conventional plant populations and row widths used in sugar-beet production. In five trials, the diploid cultivar Celt was sown at three row widths: 51, 56 and 61 cm. At each width, seed spacings were adjusted so that four seed counts, between 50000 and 113000 seeds / ha, were sown. In four of these trials, plant establishment was 78 to 90% and yield (root, sugar) and sugar concentration were not significantly affected by the plant population density achieved. In one trial, where plant establishment was 58%, yield and sugar concentration continued to increase up to the highest plant density of 65 000 plants / ha. There were no yield or quality differences between 51-cm and 56-cm rows. On average, there was a reduction of 3.5% in extractable sugar yield with 61-cm rows; this was highly significant in one experiment. These results suggest that no change is required to the target plant populations used in Ireland. For those currently using 61-cm rows, a small yield increase may be achieved by reducing row width.
