Other claims from this paper (10)

Intervention effect Nitrogen timing had little effect on foliar disease necrosis.
Intervention effect Delaying all nitrogen until April significantly reduced yield versus split March and April dressings in two of three years.
Mechanism The yield reductions reflected small differences in 1000-grain weight.
Intervention effect Spray number significantly affected foliar necrosis.
Intervention effect Spray number significantly affected grain yield.
Intervention effect One fungicide spray increased average yield by 16%.
Intervention effect Two fungicide sprays increased average yield by 32%.
Mechanism Yield increases were attributed to more ears per area and greater grain weight.
Intervention effect Fungicides delayed the onset of brackling.
Intervention effect Fungicides significantly reduced brackling amount.
