Optimal corn seeding rates can depend on a number of different factors. K-State's Crop Production Specialist, Dr. Ciampitti, discusses those factors and offers guidelines for producers as corn planting time draws closer.
Deciding on the optimal corn seeding rates for your fields can be tricky when you factor in the hybrid, environmental conditions, and management practices. Learn more about this process and what new research is being done at K-State to help producers make this decision.

As planting season for corn is around the corner, producers need to determine their corn seeding rates. Plant density needs to be determined seasonally, depending on the expected growing conditions. In rainy years, a producer may increase the target plant density and obtain an increase in profit provided there is sufficient nitrogen fertilization. Under dry conditions, farmers should consider cutting back on plant density. This applies primarily to dryland corn production.
As the planting season for corn begins, producers need to decide their corn seeding rates. The plant density necessary to optimize yields depends on the expected resource availability, primarily water and nutrients. For 2023, the key factor is linked to water availability at planting and the precipitation forecast for this season.
Seed cost is a critical economic factor and selecting the proper seeding rate is a key management practice for soybean production. This article reviews in greater detail several key factors in choosing the optimal soybean seeding rates for your production system.
