To maximise the yield of irrigated winter wheat
There is a difference between maximising biomass and the optimal biomass for maximum yield in a particular environment.
Maximising biomass creates agronomic problems such as increased foliar disease and early weed competition.
Irrigation can supply moisture during grain fill but cannot control the temperature - many of the winter wheats mature too late to avoid heat stress during grain fill.
