Key messages
These data demonstrate a significant yield response to teh application of 20kg P/ha when compared to teh control. There were no yield differences to the various treatments.
The trial was moisture stressed in late spring but moderate grain protein levels indicate that the trial was not stressed for nitrogen.
Visually it was difficult to pick up any differences between treatments, however the poor growth control was very evident throughout the growing season and the Airseeder treatment appeared to lack early vigour, but at the end of the season this was not apparent.
The application of zinc as either foliar or as fertiliser at sowing (Granulock Supreme Z treatments) did not result in additional yield.
The liquid treatments did not prove to have any significant benefit over the solids fertilizer products; contradicting results from SFS Mininera trials in 2007 where liquid fertilisers proved to have distinct advantages as conpared to solids.
