Group Trials Wheats
During 1997, the Newdegate Crop Improvement Group evaluated Agri-culture WA's new wheat varieties along with traditional varieties grown in the district.
The varieties were tested under commercial farming conditions using the machinery of Newdegate farmer David Butcher.
The trial plots were 12.2 m wide, one air-seeder width, and 100 m long. Seeding rates and agronomy were the same for all varieties. Two replications were included to get a more accurate yield. The demonstration was conducted on loamy gravel soil, which is a common soil in the district.
Westonia, Trident and Cunderdin were the high performers of the trial. Trident topped the yields at 3.54 t/ha with a grade of Australian Standard White (ASW), although the new variety Westonia was a close second and achieved the higher grade of Australian Premium White (APW).
The two new noodle varieties Arrino and Calingiri performed well and both made the noodle grade, assuming they are accepted as noodle wheat in 1998-99.
"Stretton and Perenjori are currently my main varieties and I'm looking to replace Stretton with Westonia," Mr Butcher noted. "I'm also keen to get hold of some Calingiri, after the way it performed this year."
