One ear the corn. The doesn’t seem favor it holds much value. However even despite I’m a corn farmer growing about 850 acre of corn, there is a many worth in one ear that corn. Let’s perform some math.

You are watching: How much is an ear of corn

*
In late summer a few weeks after pollination we can use a basic formula to gain a rough idea of what sort yield we could expect in ~ harvest. I have tendency to usage the productivity Component Method. Since we can’t count 10s of hundreds of ears in one acre that corn in a practical manner we usage this technique to extrapolate an estimate of yield based upon a much smaller area. 1/1000th of one acre to be exact.

With the productivity component an approach I measure off 17.4 feet that a corn row. Then ns count the number of ears within that distance. 17.4 feet amounts to a thousandth of an acre in the 30″ row spacing we plant with. For this reason if ns count 32 ears in that area I merely multiply by 1,000 to number the number of ears per acre. 32 ears is 32,000 end an acre.

It simply happens to be 17.4′ long.


Now I pick a random ear from the row to count the kernels. Either arbitrarily or together the article over suggests, the fifth ear. The idea is no to choose the finest or worst looking ear in the group. By counting the number of kernels approximately the ear (always an also number through the way!) multiplied by the number in a row follow me the size of an ear I get the number of kernels on the ear. Allows go with an nice ear of 16 around and 32 long. 512 kernels.

512 x 32 = 16,384

Now this brand-new number acquired from kernels multiplied by ears is divided by a factor based on what ns think the general problem of the ar may be. I usually start with 85. A lower variable can be offered for much better conditions. Greater factors are offered for worse conditions. This will give a bushels per acre estimate. This practice have to be repeated and also average several times in the same ar for a an ext representative figure.

16384 ÷ 85 = 192.75bu/a

192.75 bushels every acre. That’s a pretty an excellent crop! at harvest the productivity monitor (properly calibrated!) will tell us the genuine story. This method gives united state a beginning point to begin thinking around selling chop ahead the harvest or not. It isn’t supervisor accurate. Critical year my estimates were way low. I actually try to it is in a tiny conservative as soon as estimating yield. I’d fairly be pleased v a bigger harvest than a smaller sized one than expected.

So how about that one solitary ear? If we can control to gain one more great ear per 1/1000th of one acre measure up what go that median to me?

512 x 33 = 16,896 16896 ÷ 85 = 198.78bu/a

A 6.03 bushel advantage from one an ext ear gained! The cash price because that harvest distribution corn in ~ my neighborhood elevator now is $4.25/bu. So in this scenario that single ear the corn this day is worth another $25.63 every acre. Over 850 acres that’s one additional $21,785.50 end the whole corn crop. That’s no tiny chunk of change! One much less ear because that each 17.4 feet is about that very same dollar lot is lost per acre. For this reason you can see that a single ear the corn is an extremely important come our operation. Also note that variety of kernels every ear can make a big difference too. This is why planting season is for this reason critical. We obtain one chance every year to obtain each little seed turn off to a great start. And a good start gives that particle a an excellent chance to create a plant the will carry out use with one ear at harvest time.
