White
Food Grade Corn:
2002 Performance – Allen Geyer, Peter Thomison, and Rich Minyo
White
corn is one of several specialty crops receiving greater attention by Ohio
growers as an alternative to yellow dent corn.
Premiums are available for white corn grown under contract.
We conducted a white corn test in Ohio at the OARDC NW Branch at
Hoytville in 2002 as part of a multi-state testing program coordinated by Dr.
Larry Darrah, USDA-ARS and the University of Missouri.
This is our sixth year of participation in these tests.
Results of the 2002 Ohio trial are shown in Table 1.
In 2002, 17 white corn hybrids were evaluated along with 3 yellow dent
check hybrids.
Test results provide growers with a basis for comparing the relative
performance of commercial white corn hybrids and yellow corn hybrids.
Unfavorable early season growing conditions (cool, wet weather) followed
by drought sharply cut the yield potential at Hoytville in 2002.
Table 2 provides an overview of white corn performance at Hoytville since
1996.
Multi-state
white corn yield test program results are published yearly in “White Food Corn
– 2002 Performance Tests, Spec. Rep. 547.”
Data presented in the publication include food quality characteristics as
well as the typical agronomic traits.
