Corn increased on Wednesday amid concerns that rains from Louisiana to Ohio will delay planting in the U.S., the world's largest producer and exporter of the grain.

Corn futures for May delivery increased by 1.9 percent or 11 cents to $5.95 a bushel on the Chicago Board of Trade.

Corn increased by 68 percent last year boosted by high demand for livestock feed and ethanol production.

There are speculations that some farms may receive five times the normal rain next week leading to isolated flooding south of a line from Oklahoma City to Ohio, creating major delays in planting.

Corn planting was forecasted to drop by 8.1 percent to 86 million acres from 96.3 million last year.
