The head of the combine pushes through the corn field and grabs the stalks from the ground. Corn is ready for harvest about 20 days after the silk first appears. The low percentage of stress cracks is likely due to excellent field dry-down conditions at harvest with less artificial drying needed than in wetter years.
Corn is a warm-season annual that is best planted after the soil temperature reaches 60°F, usually two or three weeks after the last frost in spring. Sorting for quality in the field also decreases the time required for culling in the packinghouse, which means the product can move to the cooling step more quickly.
In addition to the corn crop, soybeans stressed by drought are dying prematurely and should also be harvested early. A large burner fan pumps air, sometimes over 200 degrees F, to dry the corn. As a result, the silage may have high levels of foul-smelling butyric acid, with a higher pH and high dry matter losses - in addition to poor feed quality, palatability and intake potential.
If the popcorn is "chewy" or the popped kernels are jagged, it is too wet and needs to continue drying. Stress-cracked kernels are more likely to be broken, produce smaller grits during dry milling, absorb water too rapidly during wet milling, and are more susceptible to insect and mold damage during storage.
"It varies by variety, but the heat and dry weather during the pod filling stage stresses the plants, making it more likely that the seed pods will break, How To Harvest Corn dropping the seeds to the ground," he says. Corn can't pop unless there's the right amount of moisture inside the kernel.
Knowing how much to harvest is as important as bale quality if farmers want to maintain sustainable fields. If you determine that it's the right time for harvesting corn, hold the stalk with one hand. Moisture Dockage: Corn may be harvested any time after grain reaches physiological maturity, which occurs at around 30% moisture.
Recent studies in Canada demonstrated that hybrids with the leafy trait (with more leaves above the ear) dried down slower than standard types in some years (see Corn Growth and Development section). Under optimal harvest and post-harvest conditions, the maximum shelf-life of sweet corn is only about 5 to 7 days.
If it shatters, the kernels are dry enough to put away as seed. Wait until the soil is warm to sow sweet corn. The grain makes up approximately 46 percent of the weight of the plant (depends on yield), while the cob and husk make up 8.2 and 7 percent, respectively.
As far as brooms go, traditional household brooms were constructed by using the tassel spikes from a plant called broomcorn.” Broomcorn (Sorghum bicolor) resembles sweet corn, but actually isn't the same type of plant as Zea mays and doesn't produce edible ears.
Some farmers feel the best brush is harvested when the plant is in flower, or at most when the seed is only slightly formed. Even though the corn kernels are yellow, the cob from this field corn is red. Plus, finishing harvest earlier potentially gives you more time for post-harvest tillage and more through out clean up before the snow flies.
