  2. Managing Corn and Nitrogen with Water Excess Conditions

    Author(s): Osler Ortez , Author(s): Greg LaBarge, CPAg/CCA , Author(s): Alexander Lindsey , Author(s): Wanderson Novais

    Excess water challenges plant growth and fitness in farming systems. Depending on the geography, dramatic fluctuations and extremes in weather patterns have been experienced in Ohio, the US, and other parts of the world (e.g., droughts, floods). Research has shown that such events have increased in frequency and intensity over the past 50 years, making farming more challenging.

  4. Corn Growth and Development: Crop Staging

    Author(s): Osler Ortez , Author(s): Alexander Lindsey

    One of the bottom-line activities in growing crops should be understanding and keeping track of crop growth and development. Crop growth is related to the increase in size. It is influenced by factors such as temperatures, water availability, stress, competition, and fertility. Crop development relates to the progress in stages, and temperatures primarily drive it.

    Crops Under Water – Crop Stage is Critical for Recovery

    Author(s): Alexander Lindsey , Author(s): Mark Sulc , Author(s): Laura Lindsey , Author(s): Osler Ortez , Author(s): Peter Thomison

    Large rain events seem to be trending this year in many parts of Ohio, especially in Northwest Ohio where 3-5 inches of rain fell in 24-48 hrs. This can lead to standing water (flood) conditions or waterlogged soils (the root system is saturated). In some areas, this may have resulted in a partial and complete immersion of plants, especially in low spots, on river bottoms, and along streams.

  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. 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

    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.

    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! 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.
