Aims

The majority of durum growers are trying to push yield towards 10 tonnes/ha which is resulting in some variability in quality and potential downgrading if protein requirements are not met. This trial aimed to investifgate end of season nitrogen (flag leaf) application, growth regulants and irrigation strategies and their influence that these have on final yield and quality.

Key messages

- Although this trial wasn’t executed exactly as planned due to weather there were still some good to be drawn out of it.
- Soil testing is critical prior to planting a durum crop to avoid under or over application of fertilisers.
- When applying fertiliser to target 7+ tonne crop, it is important you have the water required to meet this yield commitment. As seen in this project, when top dressing with these larger amounts of nitrogen, the water use of these crops increases dramatically with the crop drawing from deeper and harder over the same period of time as crop with less N applied.

Event Date Type Effect
Spray damage

The crop was sprayed with Achieve on the 14th of July to control ryegrass. Following this the crop suffered some damage which meant that the growth regulant treatments planned were not applied as this damage slowed growth enough to not warrant it.
