Sweet white lupin: a potential crop for Ontario

Abstract

Sweet white lupin (Lupinus albus is an emerging crop in Ontario and, in 1993, up to 600 ha acres of lupin were planted. This crop is adapted to cool and moderately warm climates, is frost-resistant to -2°C, requires sandy to loamy soils, requires inoculation with Bradhyrhizobium sp. to achieve high yield, and improves soil structure and nutrients when included in a crop rotation. Effective weed control is a critical factor in crop production. The harvested seed of sweet white lupin is primarily used as an on-farm source of protein. -from Authors
