Mingenew trials put the spotlight on high yielding canola

When the Morgan family was looking for a new quality hybrid canola option for the yield, oil and weed control benefits they needed, they turned to their local farming group.

In the 2013 Mingenew Irwin Group’s Roundup Ready® canola demonstrations, Nuseed GT-50 provided the equal highest yields at 1.82 t/ha and highest returns of $961/ha.

This year, Nuseed GT-50 is a significant part of the Morgans’ hybrid canola planting, with 300 hectares growing on their property south of Mingenew.

Scott Morgan farms with his father, Adrian, and brother in law, Gerard, growing 5,500 hectares of wheat, lupins and canola south of Mingenew and at Wongoondy, north of Mingenew.

“We tend to use higher quality hybrid canola varieties that have better vigour and yield more with a higher oil percentage,” Mr Morgan said.

“The extra yield and higher oil we can achieve with hybrids puts us in front and while we’re making good gross margins from canola, it’s also giving us clean paddocks for next year’s wheat crops.”

Nuseed GT-50 is a mid-maturing Roundup Ready hybrid canola variety. They are also growing some early-mid maturing Roundup Ready canola and a triazine tolerant variety.

“We are growing more Roundup Ready hybrid canola than ever before and we’re getting to the stage where ryegrass is becoming easier to manage,” he said.

In deciding to try Nuseed GT-50, Mr Morgan said he looked at local trials and National Variety Trial results and talked to other growers in the area.

“There were growers who received less rain than we did last year whose Nuseed GT-50 crops yielded 1.8 t/ha to 2 t/ha,” he said.

In the large scale Mingenew Irwin Group demonstration conducted by Sebastian Recabarren and Debbie Gillam, Nuseed GT-50 achieved significantly higher yields than six other Roundup Ready varieties and performed equally as well as 43Y23 from Pioneer.

The crop was grown on sandy loam soil with a growing season rainfall of 280 mm.

Mr Morgan said the 2014 season started well, with 100 mm of rain in May.

“All of the crops bounced out of the ground and the rain in June and July came at just the right times to keep them going,” he said.

He said Nuseed GT-50 was sown on two soil types on their property.

“On the good country, the Nuseed GT-50 established well and is looking really good,” he said.

“It produced a big cabbage to shade out weeds, and its pace of development has kept up with the earlier maturing varieties.”

On the lighter, sandier soils, Mr Morgan said they may have been better sticking with an earlier maturing variety.

However, the Nuseed GT-50 did give a good strike rate at establishment because its smaller seeds provided a higher number of seeds per kilogram at their standard sowing rate of 2.5 kg/ha.

They are now waiting on critical spring rains to finish off the crops well and provide good yields.
