Having established that the white-seeded amaranth (grain amaranth) can supply both green leaves and seeds (grains) for the Nigerian consumers, there was a need to find cultivars that could yield enough grains to be profitable for an amaranth farmer. Several lines (>100) were screened, with the opaque and creamy-colored seed as the ultimate target. These cultivars, NHAm 261-1 and NHAm258, were selected for yield trials. It was possible to have a high seed rate of 100 plants/m2, and thinning to 22 plants/m2 at the end of 6 weeks. These 22 plants were left to mature, and a maximum of 20 plants/m 2 were evaluated for grain yield. These two cultivars were found to give good fresh shoot yields as well as capacity for up to 3000/m2.
