  • Seed Treatment Guide

    The concept of treating seed to protect it from pests has been around for centuries. The 18th century solutions of salt brine, arsenic, or copper sulfate have been replaced by more effective, safer products to help corn growers maximize the genetic yield potential of every hybrid.

  • Spring Anhydrous Application and Corn Planting

    When applying anhydrous in the spring there is a risk of injury to corn. This issue contains some tips and guidelines to follow in order to reduce the risk of injury.

  • Choosing the Right Planting Rate

    Starting with the right plant population is an important tool corn growers have for maximizing performance. Don’t let plant population be your limiting factor. Control this aspect of corn production management and you’ll be rewarded with high yields.

  • Stalk Quality and Harvest Priority

    An important management decision corn growers must make is scheduling harvest to maximize yield and profitability. Evaluating stalk quality is one of the primary factors used to identify fields that need to be moved to the front of the harvest schedule. Stalk quality can be compromised by a combination of cannibalization and stalk rots.

  • Harvest Timing

    It's never too early to begin planning for harvest. It takes time to move a big crop through the grain channel, and high moisture grain slows the logistics even more.

  • Delayed Planting Considerations

    When wet conditions delay corn planting, growers start to consider changes in field operations that allow planting to occur with as little additional delay as possible. Several field operations can be adjusted with little impact on overall performance. Hybrid selection, however, is one of those management decisions that needs to be held firm despite delayed planting conditions.

  • Optimize Plantability

    Seed size and weight varies by hybrid but can be planted accurately by any planter when proper planter adjustments are made. Planter manufacturers give a range of settings to use for different seed weights and these are a good starting point for planter calibration. To further refine the calibration process Wyffels provides the following chart of recommended planter settings for seed size and weight.

  • Planting Considerations

    At planting time there are some important topics that can affect profitability. Each year presents unique challenges and opportunities. Which is why it’s so important to always be mindful of management decisions that can minimize your risk.

  • Performing Yield Estimates

    Estimating whole field yields can be difficult and variable. Increase the number of ear samples obtained and thoroughly cover the field to obtain your best estimate.

  • Replant Considerations

    Each year it seems a few acres are replanted somewhere due to adverse environmental conditions. If the decision to replant is made there are a few factors you must take into consideration to ensure maximum yield potential. Replanting presents some unique challenges, but with proper planning they can easily be overcome to set the new planting up for success.

  • Corn Scouting Calendar

    The following calendar and photos can be used as a guideline for scouting corn insects and diseases. The specific time for scouting is affected by planting date and growing degree day accumulation.

  • Herbicide Tolerance of Wyffels Hybrids

    These ratings are meant to serve as a guide for a hybrid's tolerance to some commonly used herbicides. Ratings are based on field observations where herbicides were applied postemergence.

  • Corn Grain Fill

    Grain fill is a very important yield determining period for corn. Keeping the plant healthy is important going into the grain fill period. Stress during grain fill causes yield loss through kernel abortion and by reduced kernel size and weight.

  • Sidedress Nitrogen in Corn

    Nitrogen (N) is an essential nutrient for successful corn production and there is never a good time to be short of N. Various application methods can be used to ensure N availability to the crop all season long. The application method that poses the least risk of N loss is applying after corn emergence, commonly referred to as sidedressing.

  • Field Drying vs. Bin Drying

    Some of the risks associated with leaving a crop in the field to naturally dry were discussed in a previous Between the Rows entitled “Harvest Timing”. The article discussed how stalk quality could be compromised this year due to leaf diseases, pre-harvest root lodging, N deficiency, and overall high yield potential. The bottom line is, the longer a crop is left in the field to dry, the higher the risk of yield loss due to root or stalk lodging, ear drop, animal damage, ear rots, or mechanical loss.

  • Postemergence Corn Herbicide Applications

    One result of a condensed planting season is an equally condensed postemergence spray season. All postemergence herbicides have specific guidelines to minimize crop injury, including a specific window of application timing.
