TYPES
White dent corn
White corn types are equal to yellow types in carbohydrate content but are deficient in vitamin A. White types are used primarily for human foods, breakfast cereals, and grits. Almost all white types are grown under contract; therefore, it is advisable to have a market before growing. Contracts for growing white dent usually offer a premium over the yellow dent price. White hybrids in maturities adapted to Pennsylvania are scarce, however, and their yields may not be competitive with yellow dent yields. A standard yellow dent check hybrid produced 20percent more grain yield than the best white hybrids in a Penn State yield trial. Yield data should be a prime concern of the producer before growing white corn.
White corns must be grown in isolation from yellow dents to prevent cross-pollination. A mixture of white and yellow downgrades either type at the market.
