With so many Bt trait offerings on the market today, it can be challenging to determine which package best fits your farm. Each package contains different combinations of traits with different levels of effectiveness against specific pests. Understanding best management practices is critical to ensuring control options for years to come.

A successful harvest depends not only on crop conditions but also on properly functioning equipment. While you can’t eliminate all harvest losses, you can identify the source and adjust harvest equipment for optimum performance.

Fertilizer programs should begin with accurate soil testing. Growers who can self-sample reduce costs and better understand their soil situations. Review best practices so your samples lead to more reliable results and more educated management decisions.

Grain corn ear molds can lead to yield loss at harvest. If mycotoxins are present, grain may be toxic to animals and ultimately unusable. It’s important to understand environmental conditions that lead to diseases and how those diseases affect grain.

Factors that stress corn throughout the growing season can lead to stalk rots, which can lead to yield loss due to premature plant death or lodging. Understanding stalk rots risk factors and management practices are critical.

It is a common belief that high heat and humidity are ideal for corn growth. In reality, high temperatures, especially high nighttime temperatures, can reduce corn yield potential by increasing respiration.

Zipper ears, or ears with missing kernel rows, are a result of stress during pollination or grain fill. Ears affected by zippering have kernels that developed poorly or more slowly than other kernels or have ovules that aborted shortly after pollination. It’s important to understand how and why zipper ears occur and how to minimize their occurrence in the future.

Stand establishment depends not only on the success or failure of germination but also on early season stresses. If you notice early stand problems, carefully examine damaged seedlings to discover clues to the likely causes.

By properly identifying the various developmental stages in early season corn growth, producers can make well-informed decisions on replanting, applying herbicides, managing insects and more. Make sure to understand what to look for and how to differentiate the stages.

Many farmers feel it is a greater agronomic benefit to apply nitrogen (N) in the spring rather than in the fall, because it coincides with the nitrogen needs of the corn crop. With this thought, a key question of many growers is, “Is a spring nitrogen stabilizer application still needed?”

Northern corn rootworm (NCRW) is one of the most damaging corn pests in North America. Because the NCRW typically has a one-year life cycle, rotating corn with another crop has been a successful management strategy. Unfortunately, some populations of NCRW have successfully adapted to a corn soybean rotation and now have a two-year life cycle. This is called extended diapause because the eggs remain dormant in the soil for almost two years before hatching.

Maximizing yield starts with correct planting, and correct planting starts with adjusting the planter to the proper settings. Carefully check planting equipment before you hit the field this spring.

Producers who plant insect-traited corn are required to manage refuges to preserve Bt technology. With so many trait options, following refuge management guidelines has become more complicated. SmartStax^® Refuge Advanced^® available in Mycogen^® brand hybrids simplifies achieving higher whole-farm yield potential by making refuge management easier. Refuge Advanced ensures refuge compliance in the Corn Belt¹ with a blend of 95 percent SmartStax seeds and 5 percent non-insect-traited refuge seeds in one bag.

Before planting, producers planning to use Mycogen^® brand BMR and TMF corn hybrids should carefully select which fields will be used for corn silage in order to maximize quality and yield.

Like a house with a poorly prepared foundation, corn plants with rootless corn syndrome (or floppy corn syndrome) between the V3 and V8 growth stage can topple at any moment, leading to stunted growth and even plant death. What causes this phenomenon and how can plants survive?

Early season seedling damage can significantly reduce yield. Scout cornfields regularly and diagnose problems before economic losses occur.

Planting larger seeds creates challenges. Growers should follow some basic management tips.

Extensive university research illustrates that corn planted in a twin-row configuration can have a significant yield advantage versus a single-row crop. Several factors support this conclusion.

Proper harvest management can help obtain the quality and tonnage that Mycogen brand BMR and TMF corn silage hybrids are designed to bring, and help maximize efficiency and profits from using high-quality corn silages on your dairy. Agronomist Jon Erickson offers five steps for a silage harvest.

An important part of corn silage production is proper and timely harvest management. Follow these guidelines when harvesting Mycogen^® brand Silage-Specific™ hybrids to be rewarded with corn silage that can help add profit to the bottom line.

The optimum time to select corn hybrids for the next season is often in the fall, shortly after harvest is complete and your observations from harvest are still fresh in your mind or can be reviewed in your records. Additionally, early ordering often can help ensure availability of hybrids and seed sizes that best fit your farming practices.

Harvesting corn for silage leaves little plant residue on the ground to help control water runoff and soil erosion. A cover crop either interseeded before or planted immediately after silage harvest will help protect the soil from wind and heavy rains. An established cover crop also helps improve soil structure and uptake of nutrients.

It can be difficult to schedule irrigation, herbicide application and harvest if you don’t have a good handle on corn maturity. Identifying the milkline and blacklayer will help gauge the stage of corn growth and estimate physiological maturity.

Dry summers and relentless pests increase your corn crop’s susceptibility to aflatoxins, which are harmful to livestock. Reduce your exposure with effective management.

Early frost at harvest can lead to high or uneven moisture, low test weights and increased foreign material. Careful planning and management of drying and storage can help maintain yield.

Many factors contribute to how early frost in the fall will affect corn harvest and the expenses associated with drying and storage. Damage severity will depend on the stage of the crop, the duration of freezing temperatures and subsequent plant damage.

Heavy wind and rain late in the growing season can dramatically affect corn. Flooding, downed plants and disease are just a few of the potential management challenges related to extreme weather. Consider your options for recovering as much value as possible and take precautions when storing and feeding damaged corn.

Since the adoption of corn hybrids with biotechnology traits, growers have continued to see more consistent 200-bushel-plus corn crops in past seasons. However, increased yields have created the challenge of dealing with increased levels of residue when planting next year’s crop.

Soil acidity is one of the primary fertility issues that can limit crop growth. High levels of acid can reduce nutrient availability, restrict root growth and increase the toxicity of some elements. Soil acidification occurs naturally as the result of rainfall, plant growth, breakdown of organic matter and the application of ammonia fertilizers. Applying lime reduces soil acidity and is a source of calcium (Ca) and magnesium (Mg).

Slug damage in corn and soybeans has increased with the adoption of no-till and minimum-till practices. Because rescue treatment options are limited, growers should take steps to prevent slug damage.

Strip-till is a conservation system that uses minimum tillage. It combines the soil-drying and warming benefits of conventional tillage with the soil-protection advantages of no-till by disturbing only the soil that will contain the seed row. Strip-till rows are usually about 8 to 10 inches wide. Because special equipment is required for this type of tillage, understanding what is needed for a strip-till system can help you determine if it’s the right practice for your fields.

Crop harvest removes valuable nutrients from the soil. Understanding the amount of nutrients removed is crucial to understanding how to fertilize for the highest yield potential next season. With high input costs, it can be tempting to skimp on nutrients to save cost. Over time, however, this approach can reduce yield potential and profitability.

Spider mites can be a major corn pest in western regions of the United States. Mite infestations damage corn by removing photosynthates from the leaves, resulting in loss of leaf tissue, stalk breakage, kernel shrink and premature death. Damage from spider mites may lead to yield or tonnage loss and poor quality silage with low relative feed value.

If foliar diseases threaten brown midrib corn (BMR) silage fields, growers can mitigate risks under the right circumstances with proactive management. Are you familiar with best practices for protecting your silage crop?

Hailstorms regularly strike growing corn fields. But not all damage is created equal. Know how to accurately assess yield loss.

Mastering foliar fertilizer application methods and timing help maximize your crop’s efficiency. Follow these guidelines for proper foliar fertilizer application.

Severe drought can cause unsafe levels of nitrates to form in corn plants, especially in the lower stalks. Although precautions during silage harvest can reduce nitrate levels, dairy producers should be cautious when feeding drought-stressed corn silage.

Summer drought noticeably limits corn silage production by reducing ear size and stalk growth. As few as four consecutive days of visible wilting during vegetative growth can reduce grain or forage yield by as much as 5 to 10 percent. Yield losses of 40 to 50 percent are possible if high temperatures and limited rainfall coincide with silking and reproductive stages.

Applying a portion of your crop’s nitrogen (N) requirement with irrigation water is a best management practice to reduce nitrate leaching in coarse soils. New irrigation technology systems have made the process of chemigating easier.

When low temperatures or frost injure young corn plants, you may wonder if these plants will recover. Carefully weigh your options and don’t make any quick replanting decisions. The key to assessing corn seedling viability is to find and observe the growing point.
