Abstract

Drought can be considered as a set of climate pressures that can result from a combination of heat, aerial, or soil water deficits, as well as salinity. The diversity of drought created from these phenomena has led to the selection of numerous types of resistance mechanisms that operate at different levels of life organization. This entry reviews drought in the context of crop production, defining circumstances in which growth or yield of the crop is reduced because of insufficient water supply to meet the crop’s water demand.
