Prior to the introduction of genetically modified (GM) insect-tolerant maize (Zea mays L.) in 1997, most part of the Argentinean production of this staple was concentrated in the humid and sub-humid temperate regions. Early spring sowings minimized the risk of water deficits around flowering and yield reduction due to pests. GM maize was the technology for optimizing sowing dates to synchronize critical periods for kernel set determination with those times of the year when water deficits are less probable, thus reducing large interann
