Picture of the week: Estimating Corn Yields
This picture comes from Wisconsin and depicts how farmers can estimate their corn yields. To calculate corn yields, according to the University of Illinois College of Agriculture's Agronomy Handbook, first count how many ears of corn are in 17.5 feet of a single row of corn which will give you the amount of ears in 1/1,000th of an acre. Multiple the number of ears in 17.5 feet by 1,000 to arrive at the number of ears per acre. Next, find the average number of kernels per ear on a three ear average. This can be done by counting the number of rows on the ear multiplied by the number of kernels in each row.
This exact picture reveals 16 rows containing 44 kernels each which equates to 704 total kernels. Once finding the total number of kernels in an acre, simply divide by 90,000, which is the estimated number of kernels per bushel, you will arrive at an estimated number of bushels per acre. This field in Wisconsin had an average yield in this test area of 273.7 bushels per acre.
