'More crop per drop' drought strategy touted

Feb 24, 2015

Corn silage producers can get 'more crop per drop" with deficit irrigation, however productivity will decline, reported Dennis Pollock in Western Farm Press. Pollack based the story on a seminar at the World Ag Expo earlier this month presented by Mark Lundy, UC Agriculture and Natural Resources Cooperative Extension advisor for Colusa, Sutter and Yuba counties.

Lundy said there are certain times in the crop's development that farmers will not want to stress the corn silage - when tassels and silk are forming. At other times in its development, even if the corn is stressed, the application of more water does not bring a proportionate increase in yield.

The UC ANR advisor suggested farmers choose planting dates, varieties and cultural practices that will maximize irrigation efficiency.

“Look at what you choose to grow and perhaps plant later with a short variety or drought tolerant variety,” he said. “And get weeds under control. They take up water.”
