Irrigation For Corn
What amount of water is necessary per acre for the best possible yield
of corn under acreage conditions and proper cultivation in the San
Joaquin or Sacramento valleys?
No one can answer such a question with anything more than a guess. It
depends upon how much rain has fallen the previous winter, how retentive
the soil is naturally, and what has been done to help the soil to hold
it. Nearly all the corn that is grown is carried without any irrigation
at all on moist lowlands, which may be too wet for winter crops. If you
demand a guess, make it six acre-inches, with a good surface pulverizing
after each run of water in furrows between the rows. This water would be
best used in two or three applications.
