The Yield Factory Is Under Construction

From Stand Establishment to Ear Development

In our last Stalk Talk, we focused on evaluating stands through Net Effective Plant Stand (NEPS) and Bushels per 1,000 Plants. The question was simple: What yield potential did we establish?

By this point in the season, most fields have largely revealed their stand potential. Emergence has occurred, plant populations can be measured, and we have a good understanding of the opportunity that exists in each field.

Now the focus shifts.

The goal is no longer establishing yield potential. The goal is maximizing the productivity of every plant in the field.

From Plant Counts to Ear Size

Earlier this season we evaluated how many productive plants we had. Today we are evaluating what those plants can become.

Fields with strong NEPS and excellent emergence have already established the foundation for high yields. The next step is helping each plant build the largest, healthiest ear possible.

As the crop approaches V6 and V8 growth stages, some of the most important yield components begin to develop. The decisions the plant makes during this period help determine the size of the ear it can ultimately support at harvest.

The Ear Is Taking Shape

Around V6, the plant begins determining the maximum number of kernel rows around the ear. This establishes the ear's girth and represents one of the earliest yield components being formed.

As the crop progresses toward V8 and beyond, the plant begins determining the potential length of the ear by establishing the number of kernels that can be supported within each row.

Together, these growth stages help determine the overall size of the ear long before pollination occurs.

Simply put:

• V6 helps determine ear girth.

• V8 begins determining ear length.

The larger the ear the plant can support, the greater the opportunity to maximize yield at harvest.

Finding the Next Yield Limiter

This is one of the most important scouting periods of the season. The goal is not simply to find problems. The goal is to identify the next factor most likely to limit yield.

As we walk fields, we are evaluating:

• Nitrogen availability

• Sulfur availability

• Zinc availability

• Root development

• Weed competition

• Insect pressure

• Irrigation timing

• Overall plant health

Many of these factors can still be influenced through side-dress applications, foliar nutrition, irrigation management, and timely crop protection decisions. The earlier limitations are identified, the greater the opportunity to protect and enhance yield potential.

Capturing the Opportunity

The Max Yield System is built around removing yield-limiting factors before they become yield-reducing factors.

Planting established the opportunity. NEPS helped us measure it. Now management decisions will determine how much of that opportunity ultimately reaches the combine.

Every bushel starts as potential before it becomes production. The fields that consistently produce the highest yields are rarely the fields without challenges. More often, they are the fields where challenges are identified and addressed before they impact ear development.

The stand has already established the opportunity.

Now it's time to build the biggest ear possible on every plant.
