Hart field site group chairman Grant Roberts said there had been plenty of changes made at the site and the field day to make it relevant to farmers.

"The crops are sown a lot earlier and we're seeing the benefits of that now," he said.

"A lot of farmers are looking at where they can cut costs, so we've set up a trial looking at alternative sources of phosphorus."

There was a presentation on getting the best out of durum and the release of the new AWB Seeds variety Caparoi.

The variety is high yielding and has mid-season maturity.

It has large grain size with high protein and low screenings.

Caparoi also offers excellent foliar disease resistance, along with outstanding lodging and shedding resistance.

It has APDR classifciation in South Australia, Western Australia, Queensland and north and central New South Wales.

"Durum is making a comeback in this area, especially because of the new varieties coming through and changes in durum agronomy," Mr Roberts said.

Another trial featured at the Hart site was on wide row spacing with pulses.
