| Abstract/Contents: | "As part of a project to stimulate Norwegian seed production of common bent (syn. browntop, US: colonial bentgrass, Agrostis capillaris L. syn. A.tenuis Sibth.) field trials comparing sowing rates of 2.5, 5.0, 7.5 or 10 kg ha-1 were conducted at Landvik, south-east Norway, (58°N) from 1989 to 1994. Three trials were laid out of the forage cultivar 'Leikvin' and three trials of the lawn cultivar 'Nor', each trial being harvested for three consecutive years. While the average per cent ground cover in spring increased from 87% at 2.5 kg ha-1 to 94-96% at 7.5 kg ha-1, seed yields decreased with increasing sowing rate in both cultivars. On average for all harvests, quadrupling the sowing rate from 2.5 to 10 kg ha-1 reduced seed yield by 9% in 'Leikvin' and 15% in 'Nor', the stronger effect probably being associated with a greater competition between tillers in the lawn cultivar. Seed yield reductions with increasing sowing rate showed no relationship with crop age, but were less accentuated for crops undersown in spring wheat in a dry year than for crops established without cover crop in years with ample rainfall in early summer. Increasing sowing rates reduced plant height and panicle number in 'Nor', but had no effect on seed weight or germination in any of the cultivars. It is concluded that seed crops of common bent should be established with a sowing rate of 2-5 kg ha-1, with the lowest rate in lawn cultivars, under ideal seedbed conditions and when seed crops are sown without cover crop." |
