FAYETTE, Ohio — Severe stalk rot and ear rot plagued many of the corn varieties in a hybrid test in northwestern Ohio recently.
Yields in both the full-season and early-season tests averaged in the 150-bushel-per-acre range. The test was conducted by Farmers’ Independent Research of Seed Technologies (F.I.R.S.T.) on the Fulton County, Ohio farm of Randy Carothers.
F.I.R.S.T. manager Rich Schleuning planted the field on May 4 at a rate of 29,500 seeds per acre. He harvested approximately 23,000 plants per acre on Nov. 6. “Wet and cool conditions reduced populations,” Schleuning explained. “Conditions then turned dry during pollination. Some hybrids had severe stalk rot and ear rot.”
The soil type on Carothers’ farm is a sandy, clay loam. The field was well drained. The previous crop was soybeans treated with glyphosate.
Winning the early-season trial was Specialty Hybrids 2882VT3 with an average of 173 bu. per acre. Stine Seeds variety 9624VT3 finished second at 169.1 bu. per acre. Coming in third was Fielders Choice NG6720 at 165.7 bu. per acre.
In the full-season test, AgriGold hybrid A6456VT3 earned top honors with a 176 bu. per acre average. Stewart hybrid 7T618 produced 173.1 bu. per acre, which was good enough for second place. Channel hybrid 210-57VT3 was third with a 172.7 bu. per acre average.
