Effects of cultivation on yield locations

To compare and evaluate the yield effect from cultivation, before seeding versus a full cut system in a wheat crop.

Key messages
  • Reduced yield experienced on cultivation treatment with the drying out effect at seeding.
  • More root biomass in the early part of the season with cultivation.
  • With no sub soil moisture cultivation did not have the desired effects on yield.
