Potential of grain amaranth production in eastern Canada

The potential of grain amaranth production in southwestern Quebec was studied. Twenty-nine cultivars were evaluated in single row plots, and seven in mechanically managed plots. Yields averaged 27 g plant-1 in single row plots, and 649 kg ha-1 in mechanically managed plots. Another set of experiments evaluated different seeding dates, row spacings, seeding rates and nitrogen fertilization rates. Seeding date and nitrogen fertilization affected grain yield in one environment, and seeding rate and row spacing did not affect yield. Grains in all experiments required drying. These experiments suggest that grain amaranth could be cultivated in southwestern Quebec. Oxalate concentration and form were determined in seeds from the cultivar, seeding date and nitrogen fertilization trials, and the effects of cooking on oxalate were evaluated. Fertilization increased oxalate concentration, seeding date had no effects, and cooking increased soluble oxalate. Grain amaranth is high in oxalate, but its absorbability is probably low.
