Corn is very susceptible to drought damage because the plant needs water for cell elongation and growth. Because corn cannot delay vegetative growth, there is a danger of yield loss from early drought conditions.
In some areas, rain has been a welcome situation, but in other areas, heavy rains have caused ponding or flooding in fields. All this rain has caused concerns regarding the possible effects it could have on the corn crop.
Everyone knows that a weedy corn field decreases the yield potential of that field, but what’s important to understand is how early this yield loss can occur. Yield is determined very early in corn, usually around the V5 growth stage.
Corn Leaf Aphids are not as detrimental to yield in corn fields as aphids are in soybean fields. The biggest loss to yield is when corn leaf aphids start feeding on the top portion of leaves and the tassel before pollination starts.
When the weather makes a turn for the worst and storms roll through during the summer months, many farmers cringe as they hear the strong winds. They are worried about the crops and hope their fields are not impacted by the high wind events.
As we look at the seven most important factors that contribute to corn yield the second on the list can be a very difficult target to hit: nitrogen.
Each year across the corn growing region, producers are faced with plant diseases, either early season seedling diseases, mid-season foliar diseases, or late season stalk diseases.
What weeds, if any, on your farm have become hard to control over the past few years? I would venture to guess your answers would be all across the board with variances by region, but with some similarities.
Hybrid selection is one of the most critical decisions a grower can make for the success of their operation. A number of factors go into this decision that are related to environment, farming practices, weather, geography, and markets.
Full-season corn products, for a given area, typically have the highest yield potential, which may help offset an increase in drying costs. As planting is delayed, corn product maturities come closer together.
As we near harvest, it’s important to start determining your order of harvest for fields. This is determined by two key factors: plant health and moisture percentages.
Every year in October, this becomes a popular question. Especially in years when the price per bushel is depressed.
Stalk lodging presents itself worse in some years than others and this is one of those years. Lodging may occur near the crown, above or below the ear, and sometimes higher in the stalk.
There are several different species of cutworm that affect agricultural production in our Legend footprint, but the one that can cause the most damage is the black cutworm.
Anthracnose is a fungal pathogen that affects standability, plant health, and overall yield in corn fields. Symptoms can be seen on leaves and the stalk, both above and below the ear.
While most Midwestern alfalfa is planted in the springtime, summer seeding has its benefits as well. For those who like to plant oats with their alfalfa for oatlage or for grain, consider planting a pure stand of oats followed by a summer seeded pure stand of alfalfa.
Each summer a small insect, known as potato leafhopper (PLH), infests alfalfa acres in some parts of the Midwest. Sometimes damage is severe and can easily be seen, other times it is minor and hardly noticeable.
Weed control in all crops is critical to achieving maximum yield. In soybeans specifically, there are multiple factors that can negatively affect their growth and development. The two main factors are moisture and nutrient uptake by the weeds.
Soybean Cyst Nematode is one of the most yield robbing pests soybean growers face today, especially in Minnesota and eastern North Dakota. Soybean Cyst Nematode, commonly reffered to as SCN, is a parasitic roundworm that infests the soybean root system.
Many soybean growers in the Upper Midwest face annual challenges to soybean production. Brown Stem Rot (BSR) is an economically important disease and is the result of the soil-borne fungus Phialophora gregata  that affects the inner stem of soybean plants.
Everyone is eager to be out in the fields and planting this time of year. However, unseasonably cold temperatures and wet conditions have been the theme for much of our area.
Two-spotted spider mites are a common pest that can cause significant damage to corn and soybean crops. These tiny arachnids feed on the juices of leaf cells, which can lead to discoloration, stunted growth, and reduced yields.
Bean leaf beetles can overwinter in leaf litter and then emerge early season to start feeding on volunteer soybeans. They then will lay eggs on the volunteer plants, allowing for another flush of beetles.
Soybeans flower and mature in response to photoperiod, also known as, day length. Shorter days after June 21st trigger flowering in soybean products.
Sclerotinia stem rot, more commonly known as white mold, is a common and destructive disease. It is sometimes seen across the U.S. and Canada; however, it is more common in southeast Minnesota, northeast Iowa, and northwest Illinois.
Soybean aphid spraying has become second nature for most of us for over ten years. But there are still lots of opinions about management of them.
Spring has finally showed up for most of our area and now is the time to start evaluating winter wheat stands for winter kill. One of the main things that help winter wheat survival throughout the winter is having well established growth before freezing in the fall.
Step 1: Seeding Plant Population: Plant population for wheat is not much different than for corn, it depends on the characteristics of the variety. Depending on whether the variety tillers very well or not makes a significant difference on seeding population.
Open up any farm magazine and cover crops are bound to be found. It seems that “cover crops” and “going green” are the latest buzz words in the ag industry. Many producers are asking “what’s all the hype about?”
Growing Degree Units (GDU) is a measurement of the amount of heat needed for a corn plant to reach various stages such as tassel or maturity. Tracking GDUs is important for corn because they are not daylight determined (like soybeans)
Fall-applied nitrogen can be an excellent way to provide the nitrogen a crop needs. Any option for applying nitrogen in the fall will have the benefit of allowing planting to start immediately in the spring without having to wait for a fertilizer application ahead of the planter.
One of the most useful steps in diagnosing nutrient deficiencies, is knowing how that nutrient acts in the plant. Nutrients are classified as either mobile or immobile:
As the corn fields approach the V5 growth stage many growers are talking about all the various products or methods to potentially increase their corn and soybean yields. In terms of early season corn applications of fungicides,
Spring planting is an important time for precision and there’s little room for error when it comes to getting your crop off to a good start. Here’s a maintenance checklist to consider as you begin preparing to plant:
When using Envita with liquid fertilizer it is important to perform a jar test before a batch is mixed up for the planter. Jar testing will give the grower an indication of whether or not the Envita will mix into the fertilizer without thickening, gelling, or separating.
