To test if no-till crops grown on clay soils in the low rainfall, southern Mallee environment would yield better if more straw could be retained on the soil surface from the previous crop.
Key messages
Wheat grain yield in 2007 was increased by 0.2t/ha after the addition of 5.0t/ha of wheat straw
Straw is important for decreasing evaporation and conserving moisture in topsoil, particularly after canopy closure and when the crop is senescing
The additional moisture available under straw significantly increased dry matter production after GS65.
Inter-row sowing reduces straw burial
