• Stubble treatments involving late burning or cultivation resulted in significantly different yields in wheat, barley and oats at 4 of 6 trials conducted at Rankins Springs, Weethalle, Wirrinya, Tottenham, Tullamore and Euabalong during 2013. The yield effects were not consistent and these initial trials could not be used to predict response. • Crop establishment was not affected by stubble or tillage treatment at five of the six sites. At Rankins Springs, however, establishment was 15% higher in the burnt stubble than in the standing stubble treatment. • Visual differences in early growth could be observed between stubble treatments. Biomass in mid-August was lower with standing stubble than after burning at three sites (Weethalle, Tottenham and Tullamore) but not at Wirrinya and Euabalong. • Variety rankings were not significantly affected by stubble treatments. The best option in terms of yield was to simply grow the variety with the highest yield potential for the sowing window.

CWFS would like to acknowledge the support provided by the co-operating farmers, without their in-kind support the trials would never happened. The support provided by AgGrow Agronomy and Research at Rankins Springs site was well beyond any simple contractual arrangement between themselves and CWFS. Matt McRae, Walkers Ag N Vet, Forbes |

Cultivation treatment imposed with offset discs. Nile oats was heavily grazed by kangaroos as it was the last remaining green pick in the trial and surrounding paddock. Likely effect on yield Mitika oats was generally flattened by kangaroos resting following grazing of nile oats. The short stems of Mitika surrounded by the higher growing varieties provide comfortable secluded resting space. Likely effect on yield. |
