Estimating Grain Corn Yield


Estimating Grain Corn Yield

Estimating Grain Corn Yield

Such a corn yield estimator is necessary in the current world, as the agriculture industry grows increasingly competitive by the year. Improving corn crop yield is more vital than ever to U.S. farmers, as the global corner market is growing quickly.

You can estimate corn yield by thoroughly sampling random ears in a field and using a multiplication formula. It will take effort, knowledge, and luck to represent a field, but it can satisfy your desire for the upcoming harvest.

Estimating corn yields

The primary thing you need to perform is to count the full number of ears in 1/1,000 of an acre. The row length to count depends upon your row width as noted below:

Row length which equals 1/1000 acre:

  • 17’5″ in 30″ rows
  • 13’1″ in 40″ rows
  • 13’9″ in 38″ rows

The next step is to calculate the kernel’s average number per ear. You perform this by counting the number of kernel rows around the ear, as well as the kernel number in the length of the ear.

The key to getting the right estimates of kernel number is to really collect random samples and collect sufficient ears to produce the best estimate.

These values are multiplied to produce an estimated number of kernels per acre and should be pretty accurate if you do your part.

Anyway, in order to calculate yield, you must also combine kernel weight into the calculation. The issue with this technique and any other variant for estimating corn yield prior to harvest is that you cannot get any physical data that calculates kernel weight – restricting the accuracy of any estimate. You can also use this corn yield calculator to get great results.

The standard value used for estimating kernel weight is 0.01116. Anyway, corn kernel weight can change by forty percent or more depending upon environmental situations and hybrid characteristics. Thus, I advise picking a seed weight value between 0.0095 for stressed, dryland corn and 0.0135 for a fit crop grown with irrigation or otherwise best-growing situations.

These values are based upon seeds weights calculated from corn grown in Mississippi and correspond with 241g per 1,000 kernels for 0.0095 and 345g per 1,000 kernels for 0.01.35. This value will have a striking effect on the accuracy of this estimate, so adjust your calculations accordingly.

Corn yields formula

Yield (bushels) = field size * (KPE * ears * 1000) / kernels size

How much is a bushel of corn?

One bushel of corn weighs 56 pounds. The prices of one bushel of corn varied historically, but in the past 5 years, the average price of 1 bushel of corn ranged from three to four US dollars.

Average corn yield per acre

The average yield is approximately 85 bushels per acre. Corn yields rise by between 1.3 percent and 1.4 percent, which is a quicker pace than the growth of the world’s population.

This permits a little increase in corn use with no increase in the corn area. America is presently the world’s biggest producer and exporter of corn, with 366.6 million metric tons produced in the 2018/19 season.
