Recent wet weather across the region has resulted in notable delays in spring planting, affecting both corn and soybean schedules. Laura Lindsey, a soybean and small grains specialist at The Ohio State University College of Food, Agricultural, and Environmental Sciences (CFAES), emphasizes the importance of timely planting for maximizing yields.
According to CFAES studies, delayed planting after April can lead to decreased yields in soybeans by as much as 0.5 bushels per acre daily.
Corn is similarly affected, with potential yield reductions of up to 1.75 bushels per acre for each day of delay, as highlighted by Osler Ortez, an assistant professor and corn specialist with OSU Extension. Ortez notes that while early planting is crucial, ensuring good soil conditions at planting is equally important to avoid yield penalties.
The situation in Ohio exemplifies these challenges. Ben Torrance, Ohio State statistician with the U.S. Department of Agriculture’s National Agricultural Statistics Service, reported that as of the week ending May 19, only 46 percent of corn and 41 percent of soybeans had been planted. This marks a slight deviation from the average over the past five years.
To counteract the delays, OSU Extension agronomists recommend considering adjustments such as plant population and seeding rates. For corn, suggested plant populations range from 26,000 to 34,000 plants per acre, considering germination and emergence losses.
For soybeans, recommended plant populations increase with the lateness of the season, reaching up to 150,000 plants per acre if planting is delayed into June.
Additional strategies include selecting shorter season corn hybrids and planting soybeans in narrower rows to enhance yields. The choice of the latest maturing soybean variety that can reach maturity before the first frost is also crucial.
These expert recommendations aim to help farmers navigate the challenges of a delayed planting season and ensure that despite the setbacks, crop yields can be maximized.
