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.”
