Development and yield potential of grain amaranth in southwestern Québec

Abstract

The production potential of 29 grain amaranth genotypes was evaluated in southwestern Québec. Considerable variation was observed for all variables studied. In single row plots, grain yield per plant ranged between 13 and 73 g DM (dry matter) plant-1, while in mechanically managed plots grain yield ranged between 432 and 979 kg DM ha-1. All genotypes matured before the first killing frost, but moisture at harvest was high (average of 26%). Grain amaranth production in southwestern Québec seems possible.
