Final Stands Indicate Harvest Yield Potential

July 1, 2010 03:29 AM
Final corn stands provide a good indication of the kind of yield results you can anticipate at harvest, and it’s not too late to determine them, says Missy Bauer, Farm Journal Associate Field Agronomist.
In this video, Bauer demonstrates how to measure off 17.5 feet (for 30-inch rows) and count the number of corn plants that are present in this amount of row. She then multiples that number by 1,000 to arrive at the total plants per acre.

Try this process in four or five different locations within each field and then average the numbers to arrive at a fairly accurate, comprehensive result. Be sure to record the information for each field to reference during 2011 planting. Depending upon the results, you may want to boost or reduce plant populations in specific fields next year.
Stand Count Formulas
30-inch rows
Number of plants in 17.5 ft. of row X 1,000
20-inch rows
Number of plants in 26 ft. of row X 1,000
15-inch rows
Number of plants in 35 ft. of row X 1,000
