Quinoa cultivation in controlled greenhouse environments

According to a recent blog post at the Guardian,

The appetite for [quinoa] has pushed up prices to such an extent that poorer people in Peru and Bolivia, for whom it was once a nourishing staple food, can no longer afford to eat it. Imported junk food is cheaper. In Lima, quinoa now costs more than chicken. Outside the cities, and fuelled by overseas demand, the pressure is on to turn land that once produced a portfolio of diverse crops into quinoa monoculture.

NASA tested hydroponic cultivation of several varieties of Quinoa in controlled greenhouse environments.

Quinoa responded well to controlled environment production practices with large increases in seed production, maintenance of short canopy stature, and increased harvest index, as compared with the field.
