On Average How Many Rows Of Kernels Are On An Ear Of Corn
Kernels are actually the fruit of corn. On average, one ear of corn may contain about 800 kernels in 16 rows. Scientists found this by counting the number of kernels along each row. They believed that corn is evolved in this way to protect the seeds from birds.
There is not a definitive answer for that, but if you take a look at the image below, you can see the average kernel rows per ear is somewhere between 10 and 15. On average, an ear of corn has 16 rows of kernels, which contains around 800 kernels. If you would like to know exactly how many rows of kernels are there on an ear of corn, you will have to do some counting on your own.
Choose a kernel or two rows, and count how many kernels from the base all the way up to the tips of the ears. Count the number of ears per row, and then choose two or five ears of corn and count the number of kernels per ear, multiplying the row number by the number of kernels in each row.
Do not count the top kernels on the bottom of each ear, or very small kernels on the tips of ears. Do not count any kernels that are thwarted or at the tips of ears, as these do not contribute to total yield.

|Per Row Kernels||Contains around 800 kernels|
|Per Acre of Row of Kernel||Five bushels per acre|
Average kernel numbers by ear for all twenty-five ears sampled from the field. Actual (harvestable) kernel numbers per ear ranged between 400-600. Some particular varieties of field corn yield between six and ten ears per plant.
The number of ears per corn stalk is variable, depending on specific factors. Different varieties of corn plants will develop a number of ears, but most of the field corn grown in Iowa is bred to grow only a single, big ear, not multiple, partial ears. Genetics dictate how many ears will be grown from a single corn plant.
A single corn ear is really a flowering stalk, which produces almost 1,000 female flowers. Long before an ear of corn has kernels, it has multiple rows of flowers. Early in ear of corn development, some rows of flowers are doubling, creating rows of double flowers, as shown in the simple figure by Bortiri and Hake (2007).

You can see the remains of this arrangement if you take a close look at a cross-section of the ear of corn. Nearly 1, or potential kernels, are placed in even numbers of rows (usually between eight and 22 rows). For one, the kernels grow into neat, neat rows, and each cornear will be in an even number of rows overall.
Meanwhile, though, with hybrids that are better for planting between 30,000 and 35,000 plants per acre, there is a big difference between how many rows surround the ear, and how many kernels are in each row. For 16 rows of ears, a kernel per row is equivalent to approximately five bushels per acre (for medium plantings). In general, maize yields are between 2 and 4 bushels per acre, or 1.8-3.6 kg/ha. Corn yields are generally reported as bushels per acre, but occasionally as kg/hectare 2.5 tonnes/acre or pounds/acre 0.9 tonnes/acre.
At 56 pounds per bushel, 2.3 billion bushels of corn is more than 128 billion pounds of corn planted. One bushel of corn weighs approximately 56 pounds, 25 kg, and contains approximately 2,700 kernels. If your recipe calls for 2 ears of corn, now you can rest assured knowing it means approximately 1.5 cups of corn kernels. To be sure that you are getting the correct number of corn kernels, measure the corn packets and compare them with your recipe.

Now that you know how much corn is on one ear, hopefully that takes away some guesswork when trying to replace fresh corn with frozen corn in your favorite recipes. To answer the question how much corn is on an ear, we removed the kernels from medium-sized ears of corn. More often than not, our average corn ear yields 3/4 cups of kernels after being removed from the cob. While corn kernel yields obviously will vary depending on cob size, it was surprising to see the heavy range from 1/2 to 3/4 cup results in our medium-sized corn cobs.
Since we are considering corn grown under bad conditions, we divided 9,240,000 by 105,000 (the average number of kernels per bushel under bad growing conditions). Overall, we adopted averaging between 75,000 to 80,000 kernels per bushel for good wheat-fill conditions; between 85,000 and 90,000 kernels per bushel for medium; and between 95,000 and 105,000 kernels per bushel for poor conditions.
One does tend to come out slightly shorter, though, at 40 kernels per row, which is still a good amount. Ear size determination Row number of kernels per row are two of the different components in corn yield. Like so many processes in a corn plant, determining the number of rows per kernel in the ear proceeds in acropetal (from base to tip) manner.
Row numbers on corn ears are always equal, unless some kind of stress interrupts the development process. Some highly-inbred varieties of corn may yield row numbers that are not equal to kernels, as shown below, taken from Bommert et al. Most varieties of corn breeding for current use have anywhere between 8 and 20 kernel rows (Bommert et al.
An ear or corncob is really a flowering portion, while individual kernels are seeds. Kernels in maize are roughly the size of peas, and are attached in regular rows around a white, pythy substance that forms an ear.
Each strand will carry pollen to one spot in a developing maize ear, making it possible to grow this spot into a corn kernel. The dimensions of what will be a harvestable ear start when a corn plant has reached about knee height, and they are completed about 10 to 14 days before silks appear.
Early maturing sweet corn will have a single ear, whereas later maturing varieties have 2 harvestable ears. Commercial corn farmers only harvest the first ear as the size and quality of the second is considered to be inferior. Corn produces only one ear per stalk, as it is pollinated by the wind, not insects. The plant can devote all of its resources to producing a single, truly good corn ear, instead of spending water and nutrients producing many, less-viable ears.
If you have 30 inches of corn, choose one row and use a measuring stick to measure 17 feet, 4-inches (17 feet, 4-inches is how long the row is, which is equal to 1/1000th of an acre). The denominator (90) represents the average amount of dry corn kernels per bushel, and takes into account that you measured 1/1000th of an acre.
How do you increase the size of corn?
Growers must raise healthy plants to fulfill the kernel requirements from continued photosynthesis and fresh nitrogen and phosphate uptake in order to lengthen this growth-filling period. As a substitute, maize plants can remobilize nitrogen from their leaves and other plant components to meet kernel requirements.
Does corn grow back after you pick it?
If the growth point is still healthy, young corn plants that have been damaged by hail typically grow back. Up until the V5 stage, the growth point of maize is shielded beneath the soil surface (five collared leaves). Split a stalk down the middle to reveal the growth tip.
Can humans eat corn cobs?
Although young ears, often known as baby corn, can be eaten raw, as the plant becomes older, the cob becomes increasingly tough until only the kernels remain edible. The corncob can either be removed from the field as part of the corn stover or gathered as part of the ear (which is required for corn on the cob).
