    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.

    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.

    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. 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.
