Indiana Corn: Flood or Ponding Damage Late in the Growing Season Jul 27, 2022
Excessive rainfall events (aka “goose-drownders”, “toad-stranglers”) that occur late in the growing season can cause flooding of rivers, creeks, and streams as well as ponded areas within fields distant from […]
Corn: The “Ear Shake” Test for Assessing Pollination Success Jul 16, 2022
Pollination in corn is the act of transferring pollen from the tassels to the emerged silks of the ear. Germination of pollen grains on receptive silks results in a pollen […]
Indiana: “Rootless” or “Floppy” Corn Syndrome Jun 14, 2022
Excessive drying of the upper soil profile is conducive for the development of what some of us affectionately call the “rootless corn” or “floppy corn” syndrome. The problem illustrates a […]
Indiana Corn: Why Is Your Crop Purple? Jun 1, 2022
Like the swallows that return every year to San Juan Capistrano, it seems that purpling of young corn plants returns every year to more than a few fields in Indiana. […]
Indiana Corn: Effects of Flooding or Ponding Prior to Tasseling Jun 1, 2022
Intense rainfall events (colloquially referred to as “toad stranglers” or “goose drownders”) flood low-lying corn fields and create ponding (standing water) in poorly drained areas (depressions, compacted soil) within other […]
Indiana Corn: Dealing with Emergence Problems May 27, 2022
Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place. Seedling emergence occurs as a result of the […]
Indiana Corn: Hybrid Maturity Decisions for Delayed Planting May 18, 2022
Delayed planting seasons create a lot of frustrations for everyone involved with planting crops. One of the agronomic questions that comes up when planting is seriously delayed is whether farmers […]
Indiana Corn: The Planting Date Conundrum Apr 27, 2022
Conventional wisdom says that the prime planting “window” to maximize corn yields in much of Indiana opens about April 20 and closes about May 10. This “window” typically opens about […]
Indiana Corn, Soybeans: Maximum Weekly Planting Progress – Has It Increased Over Time? Apr 23, 2022
The number of 30-, 40-, and 60-ft wide (or larger) field crop planters across the U.S. Midwest is greater today than, say, 25 years ago. Certainly, individual farmers can plant […]
Indiana Corn: Adjust Nitrogen Rate to Maximize Profit Apr 20, 2022
Corn yield response to increasing nitrogen (N) rate follows the Law of Diminishing Returns – as higher and higher increments of N are applied, the increase in grain yield becomes smaller and smaller (Figure 1). Eventually, maximum yield occurs and applying more N does not increase yield any further. Interestingly, […]
