When water is scarce, it is often better to accept a lower yield in order to achieve the greatest yield for the least amount of water. This feature of diminishing returns at high levels of productivity (less “crop per drop” of water applied as the yield improves) is true for many resources in agricultural systems.
But not every crop responds to water deficiency in the same way; unfortunately for growers of corn, even small deficiencies in water reduce overall productivity.
This drought tip will help growers of corn calculate the amount of water a California corn crop requires under various conditions.
