 May 5, 2022 Source: Golden Harvest news release Downers Grove, IL - Golden Harvest announced today new trial data reinforcing the importance of understanding the interactions between hybrid genetics, environment and certain management practices is the key to maximizing corn yield potential. To evaluate the response of Golden Harvest hybrids to management practices, such as seeding rate, fertility and foliar-applied fungicides, the Golden Harvest agronomy research team implemented field trials across the Midwest in collaboration with local universities. Golden Harvest Eastern Agronomic Research Scientist Brad Bernhard, Ph.D., and Steve Wilkens, Golden Harvest Agronomy Manager for the East, share how pairing the right Golden Harvest corn hybrid with the right management practices can help maximize yield potential. Select the optimum seeding rate for each hybrid Optimal seeding rate is hybrid specific and environment dependent. Depending on agronomic characteristics, the grain yield potential of some corn hybrids is more easily influenced by increasing seeding rate. "When determining the optimum seeding rate, it's important to consider things like the hybrid's ear type," said Bernhard. "Hybrids that exhibit ear flex tend to produce a larger ear at lower planting populations and a smaller ear at higher populations, while fixed ear hybrids produce the same number of kernels per ear, regardless of population." Golden Harvest offers a couple hybrids that are a good choice for farmers looking to increase seeding rate to maximize yield potential, including Golden Harvest corn hybrid G10D21.
Precisely place fertilizer Precision fertilizer placement provides available nutrients close to the plant. The use of phosphorus, potassium and nitrogen helps corn plants develop strong roots, stems and foliage to increase corn yield potential. Systems for precision fertilizer application include planter-applied fertilizer, banded fertilizer and strip-tilled fertilizer. Differing from broadcast applications, which increase the fertilizer rate, precision fertilizer application works best by concentrating the same or 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.
Apply fungicide to maximize return on investment Fungicide applications can prevent plant diseases like tar spot, Southern rust and gray leaf spot from developing, while also helping suppress disease pressure that may already be present in a field. "But the right fungicide can do even more for your corn plant health than prevent disease," explained Wilkens. "Fungicide applications can also lead to increased standability and stay-green, which prolongs photosynthesis and can boost yield potential." In trials, Golden Harvest corn hybrid G11V76 consistently showed a large response to fungicide applications in both high and low disease environments. Across 14 trials, most of which had low disease pressure, the hybrid averaged a 12 bu/A yield response to fungicide.
"Providing research insights on hybrid response to different management systems is one of the ways Golden Harvest shows its commitment to our farmers," said Wilkens. "Farmers can connect with their local Golden Harvest Seed Advisor for more recommendations to maximize corn yield potential this growing season." For more considerations as farmers get deeper into the 2022 growing season, Golden Harvest offers a library of agronomy articles with actionable data and local insights to help manage fields for maximum yield potential. The Agronomy in Action 2022 Research Review also gives access to more insights and recommendations pertinent to your field. Tweet |
