NWMO | Knowing your hybrid characteristics is very important and getting more important as we go forward...
I've posted this before but I do it agian...(10y+ ago) We did a plot with two companies One biased on yield and one biased on consistancy/health, 4 popular hybrids from each.... 1/2 mile rows mirrored images with a buffer in between... Large flags centered...Plane application at brown silk on one side... Conclusion was the high yeild company was at the bottom on untreated and won by alot on the treated it was a 60-80 bushel swing... Won by enough to afford fungicide and out yield the other company... but fungicide raised yield on the company that focused on plant heath too, just not as much... Guys that don't want or have time or location for high managed type corn hybrids shouldn't plant them... As ROI will be better with consistantcy type hybrids... High yielders are subject to more than just leaf diseases... green snap, lodging, ear retention ect all come to mind... High managment takes more than just a couple spray passes... Most need harvested wet and ran though a dryer ect... So they need to really preform to ROI all the extra management.... Most State/National plot winner will plant a protective hybrid around thier plot hybrid... Or they will find a very protected field from weather... They can pump water in and out, But they can't stop the wind ect... They don't want extra energy going into building a stalk ect, just make a monster ear only... Also most companies have these hybrids but they are not in the pamplet... special use you might say... They don't grow those yields on every acre... Very seldom, if at all, dose any company plant a test plot on marginal ground, but I would bet out come would be completely different, and most likely more helpful to the end user... But show plots are always planted on good ground...
