    In 2021, 121 corn hybrids representing 16 commercial brands were evaluated in the Ohio Corn Performance Test (OCPT). Four tests were established in the Southwestern/West Central/Central (SW/WC/C) region and three tests were established in the Northwestern (NW) and North Central/Northeastern (NC/NE) regions (for a total of ten test sites statewide).  Hybrid entries in the regional tests were planted in either an early or a full season maturity trial. These test sites provided a range of growing conditions and production environments.

    Nitrogen fertilizer is a major cost in corn production and is a big lever that drives yield. However, not every pound of N fertilizer yields the same return on investment. The first several dozen pounds applied to a corn crop yields large returns in grain, with subsequent pounds still offering returns, but not as effective as before.

    C.O.R.N. Live is back as we anticipate the 2021 Farm Science Review. Nate Douridas, Farm Manager of the Molly Caren Ag Center, site of the Farm Science Review, will give an update on harvest as they begin to open fields for field demonstrations. He will give us an early look at yields and moisture and what to expect during the field demonstrations this year. Then join us for a walk through the Agronomic Crops Plots. These plots demonstrate research conducted on farms around the state and offer CCA credit opportunities during the show.

  1. Abnormal Ear Diagnosis Poster,  ACE-1. Farmers frequently encounter abnormal corn ears in their fields when the crop has experienced a major stress, such as drought, temperature extremes, disease, insect injury, or misapplied chemicals. These abnormalities often affect yield and grain quality adversely. In this poster, ten abnormal corn ears with distinct symptoms and causes are highlighted. The purpose of the poster is to help corn growers and agricultural professionals diagnose various ear disorders.

  2. Corn Disease Management in Ohio, Bulletin 804. Five to 15 percent of Ohio's corn crop is lost to disease each year, amounting to nearly $100 million in lost farm income. Corn diseases include seedling diseases, leaf blights, stalk rots, ear and kernel rots, and viruses. This bulletin describes the disease symptoms, provides color images, gives the environmental factors favoring the disease, the method of transmission and infection, and management options for the major diseases affecting corn in Ohio.

    Ohio Agronomy Guide 15th Edition, Bulletin 472. The newly revised Ohio Agronomy Guide serves as the official compilation of adaptive results and recommendations from research and educational programs. Described in this manual is information on Ohio's climate and soil, soil and water management, soil fertility, and corn, small grain, and forage crop production and management. Also, seed evaluation and weed control for the previously listed crops are discussed.
