TopCross Blend® high oil corn hybrids have added a new dimension to the specialty grain market. Producers have been able to utilize the higher oil content of the grain for their own livestock operations or contract their grain for a premium price. Little is known about the effects of cultural agronomic practices on the grain composition of high oil corn. Particularly of interest is how the percentage of oil is affected. As a result, research is needed to evaluate the effects of planting date and determine if there is a limited window of opportunity in which high oil corn can be planted without detrimental effects. During the 2000 growing season, the effects of date of planting were evaluated. In addition to this location, this study was conducted on two other university research farms and will be continued during the 2001 growing season.
