Abstract
The new white clover cultivar ‘Grasslands Pitau’ was compared with ‘Grasslands Huia’ on unirrigated Wakanui silt loam, in both mown monocultures and grazed pastures. Annual yield in monoculture was up to 9900 kg/ha. The ony significant difference between cultivars in seasonal yield was in autumn when Pitau outyielded Huia. In grazed pastures, from sowings over three years, annual yields of clover in the first year after sowing were low (<1000 kg/ha) because of dry spring and summer weather. Yields were up to 3400 kg/ha in the second year after sowing. Pitau did not outyield Huia in any season. The new red clover cultivar ‘Grasslands Pawera’ was compared with ‘Grasslands Hamua’ and ‘Grasslands Turoa’ in mown monocultures. Annual yields were up to 14 200 kg/ha, Pawera giving highest yield in spring and summer.
