Growers are always seeking ways to increase their farm operation profit. Sometimes this crusade leads to higher corn yields but less profit. The Ohio State University C.O.R.N. newsletter recently outlined twelve production practices to increase corn yields and profit.
Authors Peter Thomison and Steve Culman provide their analysis on how to grow corn field profit and yields.
In the quest for high corn yields, considerable attention has been given to increasing various inputs, including seeding rates and fertilizers, narrowing row spacing, and making preventative applications of foliar fungicides, growth regulators and biological stimulants. However, the significant drop in crop net returns that’s occurred in recent years warrants developing strategies to lower input costs. An input that might have paid for itself with $5.50/bu corn may not at $3.75/bu corn.
1. Know the yield potential of your fields, their yield history, and the soil type and its productivity.
2. Choose high yielding, adapted hybrids.
3. Follow pest management practices that will provide effective, timely pest control – especially weed control.
4. Aim to complete planting by May 10.

5. Follow practices that will enhance stand establishment.
6. Follow appropriate seeding rate recommendations.

7. Supply the most economical rate of nitrogen.
8. Utilize soil testing to adjust pH and guide P and K fertilization. Avoid unnecessary P and K application.
9. Perform tillage operations only when necessary and under proper soil conditions.
10. Control traffic over field. Larger field equipment means greater chances of soil compaction.
11. Take advantage of crop rotation – corn grown after soybeans will typically yield 10-15% more than corn grown after corn.
This may be a factor when finalizing your crop plan between corn and soybeans.
12. Monitor fields and troubleshoot yield-limiting factors throughout the season.
