Insect Resistance Management in Corn

A corn refuge is the key component of an Insect Resistance Management (IRM) plan. Proper implementation of an IRM plan is important and mandatory for corn products that contain B.t. (Bacillus thuringiensis) technology or insect protection traits. Grower compliance is critical to the success of an IRM plan, and new requirements have been incorporated in…

Seed Size and Shape Issues in Corn

Questions arise every year regarding effects of seed size and shape on plantability and yield potential.  Following manufacturers’ recommendations and considering tools to enhance plantability can help limit the risk of poor plantability. If plantability concerns related to seed size are managed properly, the effect of seed size may not significantly affect yield potential under…

Soybean Fertility Management

Nutrients are required for water transport and photosynthesis processes, and protein and oil production in the plant.  Nutrient deficiencies are one of the causes of leaf discoloration and/or chlorosis that might be observed in a soybean field and can decrease plant growth and reduce yield potential.  It is beneficial to understand the function of a…

Planting Small-Seeded Soybeans

Like most other things in agriculture, soybean seed size is determined by the interaction of genetics and environment.  Hot and dry conditions, such as those experienced in some parts of the U.S. during the 2011 growing season, can result in smaller seed. Planting smaller seed may require adjustments to planting equipment. Agronomic Spotlight – Planting…

Ear Drop Issues in Corn

Dry weather and other stress factors can lead to premature ear drop. Scouting fields and planning for a timely harvest can help minimize preharvest losses.  Weather stress can be a key factor of ear drop issues. Generally, the problem is most severe when extreme high temperatures occur at R1 (silking). These conditions can result in…
