Drip Irrigation for Sweet Corn Conserves Water and Boosts Crop Yield

A study in California’s Imperial County showed that using drip irrigation on sweet corn crops conserves water, reduces fertilizer use, and boosts crop yield. About 8,000 acres of sweet corn are planted in the county each year. In this study of 11 sweet corn fields, the six fields that were drip irrigated used an average of 37% less water than the fields that were furrow irrigated. They also showed a 5% increase in yield. The study also showed that the drip irrigation helped farmers save 25% in fertilizer costs, compared corn fields that were furrow irrigated.
