For short- cycle cultivars planted in rainfed conditions after the
end of the sanitary break (ESOY), Y is projected to decrease in
Central-Northern Brazilian regions until 2050 (Table2andFig.3a
andc).In these cases ,according to both RCP8.5 and LUCID+PC13,
the physiological effects of an increased CO atmospheric concen-
2
tration is not sufficient to offset a dramatic decrease in Y inresponse
to a more severe climate.This drop in ESOY productivity is induced
by a sharp decrease in precipitation during the transition from dry
to wet season when large-scale land-ocean interactions are less
influential (LawrenceandVandecar,2015).CostaandPires(2010)
