Plant growth and seed production of Amaranthus tricolor L.

Plant development and seed production of red amaranth (Amaranthus tricolor L.) were evaluated at Jaboticabal State of São Paulo, Brazil, through 1999-2000. Seedlings were produced in small plastic containers, and transplanted to a bed exposed to full sun in a 25 x 25 cm spacing. High percentage of mortality occurred after transplanting, and the surviving plants did not grow well. Germination percentage and speed of the yielded seeds were lower than that of the seeds initially used to grow the studied plants. However, the possibility to produce seeds of this species at Jaboticabal was confirmed. Direct sowing in beds is recommended for future experiments.
