4 Ways to Push Corn Yield Next Year

Finding the right mix of products and practices is critical to maximizing corn yield potential on your operation.
Brad Burkhart, a Corteva Agriscience market development specialist covering Indiana, offers four recommendations — based on customer farm visits and conversations with ag retailers across his region this year — to push corn yield:
- Fungicide applications contribute to more than just disease control. With longer periods of wet conditions making this year conducive to the onset of diseases such as tar spot, it made economic sense for many farmers who planted early to make a second fungicide application. These applications can protect stalk integrity and, hopefully, prevent lodging during wind events. Once those fungal structures, called stromata, become embedded in plant tissue, it can lead to poor plant health, which is a precursor to yield decline.
“Field data continues to support Aproach Prima fungicide, because it provides both curative and preventive properties for up to 21 days in corn and soybeans,” Burkhart says. “From the competitive price point to the good rating on efficacy charts, Aproach Prima fungicide will strengthen any fungicide program.”
- Ensure all inputs can provide a return on investment. In farming’s current economic environment, inputs like fertilizers must be used efficiently so they can contribute to yield potential. One way to reduce leaching and maximize nutrient use efficiency is by using a nitrogen stabilizer.
“Gaps in yield maps may be caused by nitrogen leaching from excessive rains,” Burkhart says. “Data confirms N-Serve and Instinct NXTGEN nitrogen stabilizers have increased yield by 5.2% when used with spring nitrogen applications and by 7% when used with fall applications. The active ingredient nitrapyrin inhibits nitrification, keeping nitrogen in ammonium form and available in a corn plant’s root zone for an additional six to eight weeks.”
- Start clean and stay clean. When it comes to weed control, you likely already understand the importance of a strong program approach. However, the 2024 growing conditions made it more difficult for all herbicide applications to be made at the optimal timing.
“If growers choose to bypass that preapplication and pull the planter instead, it is important to have a herbicide product that can be applied past that typical V2 or V3 cutoff,” Burkhart says. “That’s exactly where Resicore REV herbicide and Kyro herbicide are a perfect fit — both giving a farmer more flexibility and extended weed control — especially against resistant weeds. The bottom line is protecting that yield potential.”
Resicore® REV herbicide has three active ingredients and modes of action to offer control on 75 of the toughest broadleaf and grass weeds. It can be used as a pre- and postemergence herbicide on corn up to 24 inches tall and is compatible with atrazine, glyphosate and other key herbicides, as well as with nutrients like urea ammonium nitrate (UAN) and ammonium thiosulfate (ATS).
“Resicore REV herbicide basically doubles a grower’s weed control application window option 10 to 15 days,” Burkhart says. “It works well in any overall program approach to weed control. Plus, it’s now encapsulated for enhanced crop safety.”
Lesser crop response after any application means the corn plant can use energy to pack on yield rather than waste that energy trying to recover.
- Never underestimate the value of using a program approach. Using a program approach to disease and weed control will help lead to higher readings on the yield monitor during harvest. An effective program approach should include multiple modes of action against diseases and weeds. It also will help preserve the products you rely on by staving off the development of resistance.
