Va­ri­ety can bring bet­ter re­turns

Central and North Burnett Times - - NEWS -

Hy­brid canola shows adapt­abil­ity across low through to high rain­fall districts through­out south-east­ern Aus­tralia.


PA­CIFIC Seeds has wel­comed re­search from the DPI and GRDC which found hy­brid canola can out-yield con­ven­tional open pol­li­nated va­ri­eties by as much as 0.4t/ha.

The tri­als, led by DPI re­search and de­vel­op­ment agron­o­mists Leigh Jenk­ins and Ro­han Brill and funded by DPI and GRDC, com­pared hy­brids against OP va­ri­eties in 18 crop tri­als over two sea­sons at Trangie, Coon­am­ble and Nyn­gan.

A state­ment from the DPI said “hy­brids out-per­formed OP va­ri­eties by 0.4 t/ha, due mainly to larger seed size (re­sult­ing in bet­ter es­tab­lish­ment), early vigour and higher grain yield.”

It also stated that “hy­brid canola of­fers grow­ers a real op­por­tu­nity to in­crease grain yield this grow­ing sea­son”.

Pa­cific Seeds canola tech­ni­cal man­ager Justin Kud­nig said the in­de­pen­dent re­search was in line with the com­pany’s own re­search trial find­ings.

“Pa­cific Seeds re­cently con­ducted a $250,000 tri­als pro­gram and found that the more widely adapted hy­brids can pro­vide grow­ers with in­creased gross re­turns over open pol­li­nated va­ri­eties, in low rain­fall zones of around $50 to $100/ha and up to $150 to $350/ha in the medium to higher rain­fall zones,” Mr Kud­nig said.

Mr Kud­nig also agreed with the DPI’s find­ing that “the ben­e­fit of hy­brids seemed to be great­est in the western re­gions where soil mois­ture is gen­er­ally more lim­it­ing”.

“Hy­brid canola shows adapt­abil­ity across low through to high rain­fall districts through­out south-east­ern Aus­tralia, and that grow­ers can in­crease their gross re­turns per hectare by se­lect­ing key hy­brid va­ri­eties,” he said.

In ad­di­tion to the yield and oil ad­van­tages hy­brids can bring, Mr Kud­nig said the her­bi­cide tol­er­ant hy­brids of­fered more op­tions in the crop­ping ro­ta­tions, im­prov­ing over­all sys­tem prof­itabil­ity.

“In ad­di­tion to the her­bi­cide tech­nol­ogy em­ployed in many canola hy­brids, the higher biomass al­lows for en­hanced weed com­pet­i­tive­ness com­pared to OP va­ri­eties, mean­ing a cleaner pad­dock and lower weed bur­den for the fol­low­ing ro­ta­tion.”


IM­PROVED YIELDS: Ter­ri­tory man­ager Mitch Tuf­fley and canola tech­ni­cal man­ager Justin Kud­nig agree that hy­brids of­fer grow­ers an op­por­tu­nity to in­crease yield this sea­son.
