Observations from from the summer of 2015 in field W-5, planting of July 15, 2015, in Ames, Iowa. The intention was to study adaptation of quinoa to late planting because late planted quinoa would then flower in September, and set seed better than was previously possible with spring plantings of quinoa. The rows were 180 cm long, on 90 cm spacing, direct seeded on July 15, 2015, and harvested on October 26, 2015. David Brenner and Samuel Flomo

Observations from greenhouse-grown plants in 2019, fall, by David Brenner. Most of the images were taken by Sam Flomo. At planting the light timers in the campus greenhouse were set for lights on from 8 am to 10 pm (about 15 hours since it was light at 7 am). On September 7 the timers were changed to 8 am to 4 pm, so the daylengths were short and local, to force flowering, since the plants were large enough to flower well. Rove beetles were released on September 7 to control thrips.
Observations from greenhouse-grown plants in 2019, fall, by David Brenner. Most of the images were taken by Sam Flomo. Grown in a greenhouse without electric lights so the daylength is local. A pesticide application on September 6 had phytotoxic effects and killed-back or killed many Chenopodium plants.
