Hay and Silage

North East & Goulburn Murray Farmer - - FRONT PAGE -

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.
