Abstract/Contents:"Different procedures for autumn management in crops of Festuca pratensis grown for seed, in particular the possibility of combining seed production with the production of forage in autumn, were examined in eleven experiments conducted between 1993 and 1996 at various locations in south-east Norway. Methods without intensive use of regrowth, such as nitrogen (N) fertilizer application (40 kg N ha⁻¹ on 10 September, either separately or preceded by cutting on the same date, generally stimulated the subsequent number of reproductive tillers and seed yield compared with untreated plots (no N, no cutting). However, cutting before N fertilizer application on 10 September tended to have a negative effect on seed yield in 1995-96, when a mild autumn was followed by a winter with extremely low temperatures and no, or very little, snow cover. Maximizing regrowth, by the application of 80 kg N fertilizer ha⁻¹ immediately after seed harvest, never impaired seed yield when a forage harvest was taken on 10 September but did so in 1995-96, when a forage harvest was delayed to 10 October. Additional N (40 kg ha⁻¹ after a forage harvest did not significantly affect seed yield, although negative and positive tendencies were observed after harvesting in September and October respectively. When forage harvesting was delayed from 10 September to 10 October, the average yields of dry matter (DM) increased, but the forage quality, especially the crude protein content, decreased. As a result of the high yields of DM obtained (on average 2250 kg ha⁻¹ in September and 2610 kg ha⁻¹ 1 in October), use of regrowth may be of essential economic value for seed growers of Festuca pratensis."
