Hay and Silage
A NEW range of maize seed silage has been released that can help farmers boost their productivity and profitability.
The new addition to the PGG Wrightson Seed’s Corson Maize Seed silage range, Z71- F1, is producing exceptional yields, particularly for dairy farmers.
Maize grower Adam Whipp said people are now chasing Corson Maize Z71-F1 because it brings a wider harvest window, greater yield and higher profit.
“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,” he said.
Yields from the Corson Maize Z71-F1 were about 25 tonne/ha; an extra five tonne/ha increase from the traditional maize varieties on Mr Whipp’s farm.
“That extra five tonne a hectare makes a big difference in terms of profit,” he added.
Located in the heart of dairy country at Nanneella, near Shepparton, Adam Whipp runs a 100ha 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.”
However, increasing water costs and reduced allocations left Mr Whipp searching for a higher yielding maize silage that could offset this increasing cost.
Working with his local agronomist, he initially sowed Corson Maize Z71-F1 as a “trial” but said it performed that well he has made it 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 to 12 leaves on the plant above the corn cob, compared to the standard variety which has about six leaves above the corn cob.
“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,” Mr Whipp explained.
In preparation for planting, he first cut the shaftal hay, then ran over the area with a disc plough, before pre-irrigating, adding a broadcast based fertiliser and incorporating it with a grader board.
Five days later, he planted the Corson Maize Z71-F1 at 85,000 seeds/ha to a depth of 2.5 inches, and also added 50 litres/ha of liquid starter fertiliser.
Mr Whipp said for this crop he used about seven megalitres/ha of water through the growing period and deployed 300 litres/ha of liquid fertiliser that he applied with a water applicator so that it “dribbled into the irrigation channel and gave the soil a nitrogen boost.”
“Corson Maize Z71-F1 is at least 10 per cent better than the other varieties I have grown.
“I would definitely recommend Corson Maize Z71-F1 to other growers and to dairy farmers as a quality supplement to their pasture-based systems,” he said.
Feed testing on the Corson Maize Z71-F1 also showed good nutrition results, especially the starch levels.
HIGH YIELDING: Maize grower Adam Whipp said people are now chasing Corson Maize Z71-F1 to boost their bottom line.
