Abstract

Four turnip cultivars, two Swede, and one each of kale, rutabaga and Chinese-cabbage turnip hybrid were evaluated for their usefulness in extending the grazing season. The three replicates were planted on 28 July 1994 and harvested on 31 October and 3 November 1994. Dry matter yields ranged from 5460 kg/ha for Premier kale to 8877 kg/ha for Rondo turnip. Rondo turnip total yield of DM was significantly higher (P=O.O5) than all other cultivars except Doon Major Swede. Crude protein levels ranged from 8.5% to 24.3% for the tops and 5.9% to 13.4% for the bulbs, with NDF fibre levels of 17.6% to 21.4% for tops and 15.6% to 20.4% for the bulbs. All cultivars survived temperatures of -1O'C with Premier kale being the most winter hardy, surviving the winter minimum temperature of -21°C. Forage brassicas can provide high levels of quality forage for the late autumn and early winter period, significantly extending the grazing season in Ohio and the midwest US.
