What happened to very early sown cereals at Minnipa? locations
Aims

To address the question, what would happen if a commercial cereal crop was sown at such an early date?

Key messages
  • Early to mid season wheat varieties (Axe, Gladius and Wyalkatchem) sown in March yielded less than May and June sown crops.
  • A mid to late season wheat variety (Yitpi) and two barley varieties (Barque and Maritime) produced similar yields from a March and April sowing.
  • The earlier the sowing the later maturing variety and vica versa.
