New Trial Data Shows Three Key Management Practices Increase Corn Yield Potential

Select the optimal seeding rate for each hybrid

The optimum seeding rate is hybrid specific and depends on the environment. Depending on agronomic characteristics, the grain yield potential of some corn hybrids is more easily influenced by increasing the seeding rate.

“When determining the optimal seeding rate, it’s important to consider things like the ear type of the hybrid,” Bernhard said. “Hybrids that exhibit ear bending tend to produce a larger ear at lower planting populations and a smaller ear at higher populations, while hybrids with fixed ears produce the same number of grains per ear, regardless of population.”

Golden Harvest offers a few hybrids that are a good choice for growers looking to increase seeding rate to maximize yield potential, including the Golden Harvest G10D21 corn hybrid.

“This hybrid retains spike size with increased seeding rates, making it extremely responsive to higher populations in high-yielding environments,” Bernhard said. “However, it also maintains yield potential in low-yield environments at average seeding rates because it frequently produces a harvestable second ear.”

Selecting the appropriate seeding rate for the agronomic characteristics of each hybrid is crucial to help achieve high yield potential in corn production.

Accurately place fertilizer

Precision fertilizer placement provides available nutrients close to the plant. Using phosphorus, potassium, and nitrogen helps corn plants develop strong roots, stems, and foliage to increase corn’s yield potential.

Precision fertilizer application systems include planter-applied fertilizer, banded fertilizer, and banded fertilizer. Unlike broadcast applications, which increase the rate of fertilizer, precision fertilizer application works best by concentrating the same fertilizer rate or a reduced fertilizer rate in a more concentrated area near the plant.

There are a few Golden Harvest corn hybrids that respond well to precision fertilizer applications.

“I would describe the Golden Harvest G14N11 corn hybrid as a management hybrid,” Bernhard said. “This hybrid consistently responded better to banded and planter-applied fertilizer applications than other hybrids in trials from 2019 to 2021. Similar results were seen with corn hybrid Golden Harvest G15J91: fertilizer applied to planter increased yield by 40 bushels per acre (bu/A ) a turn Slater, Iowatrial site in 2021.”

Proper fertilizer placement can increase late-season standability to ultimately increase yield potential in farmers’ fields.

Apply fungicide to maximize return on investment

Fungicide applications can prevent the development of plant diseases such as tar spot, southern leaf rust and gray leaf spot, while helping to suppress disease pressure that may already be present in a field.

“But the right fungicide can do even more for the health of your corn plants than prevent disease,” Wilkens explained. “Fungicide applications can also lead to better standability and staying green, which prolongs photosynthesis and can increase yield potential.”

In trials, the corn hybrid Golden Harvest G11V76 consistently showed a significant response to fungicide applications in both high and low disease environments. In 14 trials, most of which had low disease pressure, the hybrid averaged a yield response of 12 bu/A to the fungicide.

Corn hybrid Golden Harvest G14N11 also showed significant improvement in late season yield and plant health from fungicide applications in both high and low disease environments. Yield response to fungicide applications averaged 10 bu/A in 22 research trials for this hybrid.

“Providing research information on hybrid response to different management systems is one of the ways Golden Harvest shows its commitment to our farmers,” said Wilkens. “Farmers can contact their local Golden Harvest Seed Advisor for more recommendations to maximize corn yield potential this growing season.”

For more considerations as farmers delve deeper into the 2022 growing season, Golden Harvest offers a library of agronomic articles with actionable data and local insights to help manage fields for maximum yield potential. The Agronomy in Action 2022 research journal also provides access to more information and recommendations relevant to your field.
