Corson maize silage hybrid
A new maize silage hybrid is yielding good results
PGG Wrightson Seeds has added the Z71-F1 to its Corson Maize Seed silage range, saying it brings a wider harvest window, greater yield and higher profit in situations where a full season hybrid is appropriate.
One farmer who has been trialling the new product is Northern Victorian maize grower Adam Whipp, who says yields were around 25 tonnes per hectare, which was a five tonne per hectare increase from the traditional maize varieties he used on his farm.
“Corson Maize Z71-F1 interested me because it promised above average early-growth, a tall and bulky plant with large cobs, as well as superior stay green attributes, and it delivered,” Whipp says.
“That extra five tonnes a hectare makes a big difference in terms of profit.”
Located in the heart of dairy country, west of Shepparton, at Nanneella, Adam Whipp runs a 100-hectare property where maize is a big part of his annual crop rotation.
“Generally, I’ll grow shaftal clover for the winter from
April to November, then I’ll sow maize at the end of November,” Whipp says.
However, increasing water costs and reduced allocations left him searching for a higher-yielding maize silage.
Working with his local agronomist, Whipp initially sowed Corson Maize Z71-F1 as a trial, but says it will now become a permanent part of his crop rotation system.
“The Corson Maize Z71-F1 grew a metre taller than the other variety of maize I normally grow and has 11-12 leaves on the plant above the corn cob, compared to the standard variety which has about six leaves above the corn cob,” he says.
“It also has a stay-green gene in it and it does stay greener, so when you go to chop it, it doesn’t dry off like the other varieties. The other varieties go brown very quick, but this one hung on pretty well.”
