rates of soil carbon accumulation, though that lies outside of the scope of this article. The Kernza domestication program was launched in 2002 and has reached about 1/3 the yield of wheat in comparative trials (DeHaan et al., 2018; Cassman and Connor, 2022

1/3 the yield of current modern wheat is already at the level of preindustrial wheat yields so as a post apocalyptic crop this creates a beneficial artifact from the modern era.

Grew up in wheat farming country, so from my armchair quarterback opinion, most of it hinges around whether kernza can get a trend like quinoa did. What would be the ROI? It helps if it can yields good quality hay, because in some dry years you can probably get more income from hay than for scanty wheat.
