Management studies are required to assess the full potential of white lupin (Lupinus albus L.) as a grain crop for eastern Canada. A 2-yr study to quantify the effects of management practices on morphology, yield, and yield components of two large-seeded white lupin cultivars (Primorski and Ultra) was conducted at the E.A. Lods Agronomy Research Centre of McGill University in Quebec, Canada, on a fertile sandy loam soil and a well-drained clay loam soil. Treatments included two planting dates, two row spacings (20 and 40 cm), and two cultivars, factorially combined on two soil types in 1991 and 1992. The weather was unusually cool and wet in 1992, while 1991 was more typical of the area. In both years, there were effects on plant growth, yield, and yield components due to soil types, sowing dates, row widths, and cultivars. In 1991, Ultra had 23 and 55% greater seed yield than Primorski on clay loam and sandy loam soils, respectively, whereas yields did not differ between the two cultivars in 1992. Early seeding resulted in greater yields than later seeding in both years, but this effect was larger in 1991 than 1992. Yields were higher when lupin was produced in narrower than wider rows; the effect was more pronounced on a clay loam than on a sandy loam soil. Interactions occurred between lupin cultivars and each of the three management factors (row width, seeding date, and soil type). Overall, an early seeding date in narrow rows is recommended for lupin production in short-season areas.
