After a delayed start to our planting season, we were able to plant both corn and soybean across the state in record or near-record time during May. This coincided with some timely rains and hot weather.

Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place.
Due to the cold wet weather we experienced in late April and early May, corn planted in April has struggled to emerge in many areas of the state.
Early planting favors higher yields, but does not guarantee higher yields.
Intensive study for more than 100 yr has resulted in a good understanding of corn’s (Zea mays L.) growth and development.
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.
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.
There are a few resources available for monitoring field crop diseases here in Indiana.
As spring approaches and farmers and agronomists begin to get anxious as corn planting approaches, the question that often arrives each year is when is the best time to begin planting?
