Trial Discussion/Summary:
Statistically no signifcant difference between the yields of the different varieties. Attributable to the good soil nutrition, low disease pressure and non-moisture lmited growing season.
Yield the main driver for obtaining the highest dollars/hectare return (not including any costs) but where Durum can be obtained the payment premiums make these varieties very lucrative options.
Bonnie Rock was the top yielding variety in the Corrigin CVT in 2002 as well as this year.
