Winter crop harvest has started on the canola, barley and wheat national variety trials in the northern grains region.
Department of Primary Industries (DPI) Manager Northern Cropping Systems, Dr Guy McMullen said the first to be harvested last week was the canola and barley trials at Garah with the wheat trials to come off this week.
“DPI has 21 winter crop variety trial sites located across the northern grains region of NSW,” Dr McMullen said.
“In total there are more than 60 trials to be harvested from these sites totalling more than 6,000 agronomy plots.
“Trials are located at DPI’s key research centres at Tamworth and Trangie and across a network of trial locations including Rowena, Wee Waa, Terry Hie Hie, Somerton, Bithramere Winton, Breeza, Pine Ridge, Caroona, Spring Ridge, Coonamble, Nyngan, Merriwa, and Wongarbon.
“These regional trials are located on farmers’ properties and are providing applied research and development to address constraints and investigate new technologies for grain production.
“The trials conducted by the northern cropping systems groups are jointly funded by NSW DPI and the Grains Research and Development Corporation.
“In many cases these trials are in collaboration with universities and other state departments across Australia.
“Initial results suggest that grain yields are better than expected with mixed weather conditions experienced this season including low rainfall, late frosts and high temperatures.
“This season has once again highlighted the extreme importance of stored water, right throughout the region.
“Trials this year cover a broad range of topics including nutrition (nitrogen, phosphorus and sulfur), planting time, planting depth, lodging management, seeding rate, dual purpose cereals and management of crown rot with either planting time or row spacing.”
Yield and protein and/or oil results from these trials will be available following harvest while the other quality parameters such as screenings, test weight and retention will be available early January 2014.
A selection of these results will be presented at GRDC grower and advisor updates in early 2014 throughout the region.
In addition, trial reports will again be included in the annual Northern grains region trial results published in June 2014. Results will also be used to update wheat, barley and canola variety information for other publications such as Winter crop variety sowing guide published in March 2014.
