Purple corn concerns?

For many areas of the eastern Corn Belt, a great deal of corn has been planted over the past few weeks. Some corn has emerged and is in the early stages of growth. One phenomenon that commonly occurs at the early stages of the growing season is the appearance of purple corn plants. Corn plants [...]

Uniformity continues with seed germination

The first step in corn stand uniformity is getting the corn planter maintained and adjusted to plant the corn crop as uniformly as possible. The next step in the uniformity equation is achieving uniform emergence. Germination is simply the process that allows a seed to sprout or begin to grow. Although the definition is simple, [...]

Identifying wheat growth stages: Feekes Stage 6

For determining the right timing of winter wheat management decisions, identifying the growth stage of wheat plants is critical. For example, knowing how to identify wheat Feekes Stage 6 is important because this is the cutoff timing for certain herbicides ( i.e. 2,4-D and dicamba) and also the point at which rapid development with increased [...]

Is starter fertilizer a practice to cut in 2016?

Growers use multiple fertilizer practices and application timings to address the fertility requirements for successful corn production. As the “bearish” agricultural economy continues, resulting in low commodity grain prices, many producers are looking for ways to streamline their crop production budgets, and often pose the question, “Should I remove my corn starter fertilizer program in [...]

Corn germination and emergence processes

As growers across the Eastern Corn Belt get ready to plant corn, it is important to review and understand what goes into corn the germination and emergence process. Uniform corn emergence is one of the most important aspects of stand establishment and producing high yielding corn. Understanding germination, emergence, and how environmental factors influence these [...]

Reminder about winter wheat management for spring of 2016

With recent warm weather, winter wheat has broken dormancy and begun to green up. With wheat plants no longer dormant, scouting and management of wheat fields is critical to producing high yields. As discussed earlier in the year, now is the time to plan for N applications where field conditions allow. Below is an excerpt [...]

Things to watch with corn emergence

Two aspects of stand establishment often discussed by agronomists are emergence and seed spacing. “Picket fence” spacing in corn helps plants grow efficiently and minimizes competition between them. Uniform spacing is an important part of stand establishment. More importantly, however, is uniform emergence. Plants that are just 1 leaf collar behind (due to uneven emergence) [...]

Corn planting date considerations

For much of the Eastern Corn Belt it is widely understood that the optimal planting period is between April 20 and May 10. Research has proven that corn loses yield potential daily when planted after the beginning of May. For the Central Corn Belt, the declines in yield potential due to planting delays vary from [...]

How do wheat tillers contribute to yield?

In the coming months as the weather warms up, winter wheat will break dormancy and will begin to green up. After a period of about two weeks following green up producers should evaluate their stand in order to make management decisions for their wheat crop. Part of this evaluation includes counting tillers to determine if [...]

Leaf disease: Management and consideration for 2016

As spring of 2016 approaches, producers across the Eastern Corn Belt will begin to put more thought towards their production plans and management decisions for the upcoming season. One challenge that has affected corn yields in our sales territory over the past few years is foliar disease, especially Northern Corn Leaf Blight. Anyone who attended [...]
