To provide grain growers in the central and eastern wheatbelt region with stubble management strategies utilising a ‘strip and disc’ system with fallow rotations to increase soil moisture retention for maximum yield potential in subsequent cereal crops (wheat or barley).
Draper/Tyne consistently yielded slightly higher (4.52 t/ha in 2022 vs. 4.47 t/ha for Disc/Stripper).
Draper/Tyne provides slightly higher yield but at the expense of grain quality and efficiency.
Grain Quality & Hectolitre Weight
Disc/Stripper consistently had better grain quality.
Higher hectolitre weight → denser, more marketable grain.
Lower screenings → reduced grain downgrades.
Higher protein levels (10.1% vs. 9.23%) → improved quality for malt barley
