Intervention effect In simulation, a 1 degree C temperature increase could reduce maize grain yield by 10%.
Intervention effect In simulation, a 1 degree C temperature increase could reduce maize biomass yield by 8%.
Intervention effect In simulation, a 10% decrease of rainfall from the base gave a small increase in maize yield.
Intervention effect In simulation, a rainfall increase of 10% or more, or a decrease of more than 20%, resulted in lower maize yield and biomass.
Intervention effect In simulation, a one-degree temperature increase may shorten crop duration by 4.3 days.
