University research and extension are critical in equipping producers and agronomists with the information they need to continue advancing corn production in Iowa. Incorporating new scientific findings and recommendations into today's agricultural systems must be our priority to consistently produce a high quality crop that is also economically feasible.
Seeding Rates in Relation to Maximum Yield and Seed Costs
By Roger Elmore and Lori Abendroth
7 May 2008
It takes both high seeding rates and high-yielding hybrids to maximize yields. As seeding rates and seed prices both increase, we should assess whether adding an additional unit of seed covers the cost of that seed. Given our current Iowa seeding rate research data and the current grain and seed price relationship, it appears that a seeding rate of approximately 36,000 seeds per acre will maximize not only yield but also net income.
