Inputs linked to variety
NIAB has taken a tentative step down the path of specific inputs for specific varieties.
Last year the institute treated a dozen winter wheats having different disease resistance profiles with programmes of fungicides applied at different rates. Riband, representing a very susceptible variety and Hussar, a very resistant type, were joined by 10 newer varieties.
Low disease pressure however thwarted the trial. "There were very small differences really, whatever you did," says NIABs Richard Fenwick.
He hopes this years results will be more meaningful, despite late crops, some of which are already suffering from the dry weather.
There are no plans at present to extend the work to examine growth regulator use relative to apical development, he says. Neither will seed dressings be examined.
