Scouting corn and soybean fields weekly in June will enable you to identify any yield-limiting concerns in time to address them.

As June rolls around here in southern Illinois, I start to think about wheat harvest and getting double-crop soybeans planted. It has been an interesting wheat year to say the least, but aren’t they all? In some areas of southern Illinois we dealt with stripe rust, which meant spending a lot of hours walking wheat fields in late April and early May.
As crops reach their reproductive stages, it is important to know what stressors may be lurking in your field. Diligent scouting is critical to maintaining high yield at harvest. It can be difficult and sometimes time consuming, but the commitment can have a great impact on your bottom line.
Depending on planting dates and growing conditions this year, both corn and soybeans will begin their reproductive growth stages toward the end of June and into July. This is a critical time to manage foliar diseases. Each growing season is unique in the weather patterns we see and ultimately which diseases we need to be most concerned about.
With wheat harvest officially underway across southern Indiana, I wanted to offer you a few tips about harvest and planting double crop soybeans.
When preparing to harvest wheat, the ideal moisture is between 14 to 20 percent. Below 14 percent moisture we start to see yield loss and we could also run the risk of a rain lowering test weight and quality. Air drying wheat will give you the best quality. For long-term storage, make sure to dry your wheat to 12.5 percent moisture.

A common service call I have received over the past week is yellowed corn. What causes yellow corn? Should you be concerned? What is important to remember is that the type of yellowing you see on your corn will be indicative of what caused the yellowing.

A large percentage of Ohio’s corn acres were put in the ground over the last few weeks. Since then, the warm temperatures have caused corn to emerge rather quickly, in approximately five days vs. the April planted corn which, in some cases, took up to three weeks! As our customers are out scouting their fields, several of them have noticed a reduced stand and wondering what the causes might have been...

As the southernmost agronomist for Beck’s, I’m usually the first one to see which pest(s) will be the worst, and this year is no exception. Although I haven’t seen much disease or insect pressure (up to this point), I have received numerous calls about yellow tops, white spots, or purpling in corn. With that, I thought this would be a perfect opportunity to explain some of these “corn syndromes.”

Plants need conducive growing conditions all season long for optimal performance. No other period of life is more important than a plant’s first 30 days. That period from seed to a true functioning plant with an active root system needs to be as stress free as possible. What we do or don’t do prior to planting sets the tone for this early growth period.
Many of you will be sidedressing corn in the coming weeks. Nitrogen represents a significant part of the investment needed to grow a corn crop, so we want to maximize yield while being efficient in the process. Nitrogen stabilizers are one way to accomplish this goal.
Early season growing conditions can be conducive to disease development. This is especially true as corn and soybean planting dates move earlier in the growing season to maximize yields. Early season stresses caused by cool, water-logged soils can lead to increased incidence of diseases.
Wheat can become the forgotten crop this time of year. We had an unusual winter, but overall wheat looks good. As you scout your fields, keep an eye on leaf diseases and any weeds that may have escaped. If you only scout wheat once, make sure to pay close attention at flowering and if we have wet weather, make sure to apply a fungicide for head scab! As corn and soybeans start to emerge, take time to evaluate what is happening with your crop.
One thing I recommend to many farmers in Missouri is to apply poultry manure. It provides increased soil health, organic matter, and adds a good supply of nitrogen (N), phosphorus (P), and potassium (K). The average per-ton, N-P-K analysis I have taken in the past 8 to 10 years runs approximately 16-45-40 with 16 lb. N being the estimated first-year available. This means a 2 ton/A. application equates to applying approximately 32-90-80 ahead of a corn or soybean crop in addition to the organic material. Often, farmers want to apply manure on soybean stubble going to corn for the extra N benefit.
May is usually an optimum time to scout fields for early-season crop protection and management needs. Make sure to evaluate stands, weed control performance of pre-plant and pre-emerge herbicides, and the potential need for a timely post-emerge application. In corn, review post herbicide labels prior to application for any potential use restrictions with soil-applied insecticides. If a significant amount of rain has occurred since nitrogen (N) was applied, evaluating soil nitrate levels may help fine-tune your sidedress application rate.
Greetings! May is generally the ideal time to assess corn plants at the V2 to V8 growth stages to provide the best opportunity for top yield. Diagnosing any issues that could limit yield are much easier to identify today than at harvest. Therefore, scout each field to score and record populations, plant health, roots,soil conditions, weed control, and the crop’s nutritional needs.
History shows us that early planted crops yield more than late planted 8 out of every 10 years. But since we know the weather doesn’t always work out in our favor, let’s look at what could be in store if fields end up getting planted late. Here’s the positive: late planted corn does compensate somewhat. Our XL 5828™*brand (110-day) hybrid takes 2,650 growing degree days (GDD) to physiologically mature to the black layer growth stage. For every day that planting is delayed beyond May 1, that corn will compensate 6.8 GDDs.
Early season scouting and crop management are critical to maintaining and maximizing grain yield at the end of the season. It can help identify potential yield limiting factors and allow for corrective action to be taken. Weed management is another critical component. Regardless of your herbicide program, now is the time to begin scouting for early season weeds.
I’m sure everybody is just as excited that the 2016 planting season is under way! Hopefully by now, most of your corn is planted and you’ve already started planting soybeans. Choosing the correct herbicide program is paramount in protecting yield, and these programs can change drastically based on the weeds you’re targeting. Be sure to have a plan before you have a problem!
While the 2016 crop continues to take shape, I wanted to take a minute to talk about the value of tissue sampling in the pursuit of high yielding crops. Whether you want to take a snap shot of your current fertility program,or you are trying to find your crop’s hidden hunger, collecting tissue samples throughout the season can be a rewarding experience. Tissue sampling gives you a chance to see if fertilizer rates or placement are providing adequate nutrients to the growing crop. Think of this like you or I going to the doctor for a checkup!
In some areas, the window of opportunity for planting corn, and environmental conditions that followed, were not ideal for rapid germination and emergence. The cold soils and excessive rainfall we experienced shortly after planting has led to uneven emergence, delayed emergence, and an onset of seedling blights. We have also seen the use of rotary hoes in some areas with crusted soils.
