New maize hy­brids do well de­spite drought

Matamata Chronicle - - News -

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.


- T9


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.
