The relationship of corn silage harvest moisture and maturity to its quality and performance is often underestimated. Many popcorn varieties produce one or two ears per plant, so you may have enough by growing just five or six plants. The most accurate method for determining when to harvest is to measure the moisture content. I want the corn to look dried up, but when the time is right, I want the corn out of the field as fast as we can harvest.
One bushel of corn can produce about 2.8 gallons of ethanol, and the process also yields about 17 pounds of a high-protein animal feed known as dried distillers grains with solubles (DDGS). When harvested, the kernels should be hard and the husks completely dry.
Modern combines strip the husks off each ear and remove the kernels from the ears as part of the harvesting process. If the earlage is harvested while the corn is too wet, dry-matter yields will be reduced and seepage losses will be higher. However, if harvested prematurely, yield will be lower and quality will be poor.
Depending on the length of time these packages will need to be stored, stover moisture content may need to be 20 % or less. This may mean you only harvest one way and carry a dead head across the field, but if you can save yield it can be worth the time, effort and fuel.
High-moisture Ear Corn or Corn and Cob Meal: This refers to corn grain and cob material that is harvested with a combine set to return the grain and a portion of the ground cob to the hopper. This is attributed to the reduced starch digestibility of hard-textured, dry kernels in newly fermented, unprocessed corn silage.
This increase would have likely occurred with RHMC harvested at recommend moisture levels (25-30%). In some areas where a cellulosic ethanol plant is near the baled stalks may be turned into fuel. To start planting Corn, attach the sow machine to your tractor and then drive to a corner of your field.
Dry matter content of whole plant corn varies with maturity. At room temperature, harvested ears lose 50% of their sugar in 24 hours. Basically though, the process involved in harvesting and planting Corn revolves around three main parts - a). Preparation, b). Harvesting, and c). Selling.
Regardless of the harvest date, proper harvesting and storage are necessary to ensure that a good crop results in good feed. The only reliable method of determining the optimal time to harvest corn silage is to sample the crop and directly measure the % dry matter of whole plants.
Unless you plan on eating them right away, store the ears of corn in a refrigerator, leaving the husks on. They will keep for almost a week. When pricing earlage relative to dry corn grain, one must account for the amount of corn in the earlage, assign some value to the roughage in the earlage and adjust for moisture content.
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 How To Harvest Corn red. Plus, finishing harvest earlier potentially gives you more time for post-harvest tillage and more through out clean up before the snow flies.
