  1. Unusual Ears Appearing in Corn Fields

    Author(s): Peter Thomison

    Last week, I received reports of several ear oddities showing up in corn fields including the following:

    Shortened husk leaves with normal ears protruding beyond the husks

    Most corn fields have a few ears with exposed tips. In extreme situations, a high proportion of ears outgrow husks by 1/3 to 1/2. According to Aldrich et al., 1986, Modern Corn Production, observed this where “… extreme [drought] prevailed during the time of ear set with abundant rainfall and good growing conditions thereafter.”

  2. Profile of Organic Corn Growers in a Four-State Region

    Author(s): Cassandra Brown

    For decades, consumer demand for organic food has grown annually by double-digits. (1) While still a comparatively small portion of overall agricultural production, organic corn acreage in the U.S. increased by more than 55% between 2011 and 2016, driven mainly by demand from organic dairy farms.

  3. Ponding and Saturated Soils: Results of Recent Ohio Corn Research

    Author(s): Alexander Lindsey , Author(s): Peter Thomison

    Persistent rains during May and early June have resulted in ponding and saturated soils in many Ohio corn fields and led to questions concerning what impact these conditions will have on corn performance.

  4. Corn Trial

    2018 Ohio Corn Performance Test: Regional Overviews

    Author(s): Rich Minyo , Author(s): Allen Geyer , Author(s): David Lohnes , Author(s): Peter Thomison

    In 2018, 192 corn hybrids representing 24 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.

  5. Variable Rate Corn Seeding Considerations

    Author(s): Alexander Lindsey , Author(s): Peter Thomison

    As producers are planning their seed needs for next year, it is important to think about acreage, hybrids, and seeding rates. Finding the best corn seeding rate is important for efficient production, but the “optimum” corn seeding rate – the one that maximizes profitability – can vary within and among fields with small differences in soils and weather.

  1. Abnormal Ear Diagnosis Poster, ACE-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.

  2. Corn Disease Management in Ohio, Bulletin 804

    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.

  3. Corn, Soybean, Wheat and Alfalfa Field Guide, Bulletin 827
    06/2014

    Corn, Soybean, Wheat and Alfalfa Field Guide, Bulletin 827.Looking for a handy guide to take to the field to diagnosis various pest and production problems? This guide is the answer and is new for 2014! You will want one of these guides in the truck and maybe a second in the tractor.

  4. Ohio Agronomy Guide 15th Edition, Bulletin 472
    04/2017

    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.
