The prices for high-yielding corn hybrids seeds are expected to continue to rise due to ongoing breeding and technology improvements, according to Michael Langemeier, a professor at Purdue University. The increase in seed prices is also due to the effort to achieve higher yields, which involves increasing the number of seeds per acre. Research suggests that breeding accounts for 81.6% of the change in seed value, while the seeding rate accounts for 17.7%. The exact yield response to specific seeding rates is not clear, and Langemeier suggests farmers to consider using a test plot to determine the most profitable hybrid.
