What is the best way to irrigate corn?

Drip irrigation is proven to deliver up to 20% higher yields than center pivot irrigation, using the exact same amount of water. Since pivots spray water on the leaves, much of it is lost to evaporation, whereas with drip, 100% of your water is used to produce more corn.
