New maize hybrids do well despite drought
Three new maize hybrids from Corson Maize Seed have impressed many farmers after performing strongly this season despite widespread drought.
Two new maize silage hybrids, Corson T9 (G49-T9) and Corson -F1 ( Z71- F1), are commercially available, but dual purpose grain and silage hybrid Corson -A1 (C29-A1) was available only in limited quantities for 2012 planting.
an exciting new addition to the mid-season silage portfolio for northern regions and as a full season option in northern Taranaki and other warmer southern locations.
T9 produces a tall crop with large ears which combined provide high dry matter yield potential and dependable silage quality.
T9 yielded good tonnages despite severe drought and is providing much-needed quality feed for Waikato dairy farmer Ralph Gore in a tough dairy production season.
Ralph, who farms at Hinuera, near Matamata, knows a good crop when he sees one – he grew maize mainly for grain and some silage for almost 40 years before converting his 183- hectare property to dairy four years ago.
He now grows maize for silage to feed his own herd, with 480 cows milked on the farm this season.
the new- release silage hybrid Corson - T9, Ralph grew it for the first time this season with great results.
Sown in October germinated quickly.
‘‘ Considering the season, we got good yields, an average of 23 tonne/ha from a February harvest, and certainly didn’t have any rust. I will be growing it again next season,’’ he said.
‘‘Once we started getting the heat units in December it just raced away. The cropping yardstick in the Waikato is that you expect it to be fence-height by Christmas Day. One paddock was higher than the deer fence by then. I’ve grown maize long enough to know the most testing time is late January-February and it certainly handled the drought stress.’’
Waikato silage contractor Becky Walling said the good results achieved with the Corson - F1 hybrid this season meant it was now her preferred choice for maize silage.
F1 was the biggest maize plant they had grown, with big cobs, she said.
Becky and Leonard Walling have been planting, harvesting and selling maize silage to farmers for 24 years through their agricult-
it ural contracting business as well as operating their own dairy farms.
‘‘The Corson hybrids are excellent. They all have good staygreen, good drought tolerance and big cobs,’’ she said.
‘‘I am recommending Corson’s maize seed to my customers as my preferred choice.’’
New Zealand- bred Corson - F1 is a full season hybrid offering top-end performance.
Corson - A1 is an early- maturing, dualpurpose hybrid for both silage and grain.
A1 is a tall plant with large cobs and good disease resistance.
Corson Maize Seed product development manager Neil Koevoet said Corson - A1 had demonstrated exceptional performance in trials and they were excited about bringing it to the market.
Corson Maize Seed was purchased by PGG Wrightson Seeds in 2010 and is now supported by the resources of New Zealand’s largest forage seed company. Corson Maize Seed evaluates 40 to 60 new hybrids each season.
These come from two key sources: a selection of premium international maize seed brands and Corson Maize Seed’s own New Zealand product.
Doing well: New silage hybrid Corson T9 has performed strongly in its first year.
