Information presented above and where trade names are used, they are supplied with the understanding that no discrimination is intended and no endorsement by Ohio State University Extension is implied. Harvest for roasting when ears have just reached full size, or for dry corn when husks have fully yellowed. Inventories, or carryover, from recent crop years, also can influence the price of corn. In a typical year, the decision of when to harvest corn largely depends on the cost trade-off between excess harvest losses and energy costs for drying.
The additional fiber has good digestibility (55 to 70%) if snaplage is harvested in the proper moisture range (Soderlund et al., 2006). Many common corn disease pathogens such as Diplodia, Fusarium and Gibberella can attack both stalks and ears. We harvested about 40 acres near 30% and didn't harvest anything else until 3 weeks later.
For livestock producers, harvesting corn as earlage is an option that eliminates grain-drying costs and produces a product that makes excellent feed for ruminant animals. Sampling fields to measure whole-plant dry matter content should be done well before the anticipated harvest date in case corn is drying down faster than expected.
Silage harvest usually begins around 50% kernel milk which is 42 to 47 days after silking, so silking must occur by August 15-20 in order to mature before typical killing frost dates; but remember that the timing of silage harvest is dependent upon achieving the Corn On The Cob proper moisture for the storage structure (Table 1). Noting the order that fields silk will help plan the harvest queue of your fields and scheduling of custom choppers.
Corn silage harvesting (Photo 4) includes chopping the entire corn plant (stalk, cob, and corn) into a wagon or truck. If stalks lodge due to storms or wind, ears can come in contact with the ground. Although specialty varieties are available for baby corn production, baby corn can be harvested from many common corn varieties, as well.
Freezing grain at 18-20% moisture can cause ice crystals to form on the kernels. Depending on the amount of grain left in the field and the difficulty of mechanical harvest, livestock feeding may be a good option for some growers. Favorable weather leading to early planting could help to boost yield in 2017 versus trendline expectations, assuming fairly typical weather across the U.S.
The high percentage of whole kernels and relatively low stress cracks indicate the corn should have fewer broken kernels during handling than in previous years. High test weight is a grain trait that helps kernels resist breakage during threshing and handling.
The cobs are the female part of the corn plant with every kernel being a flower”. The silking date can be used as an indicator to give you an estimate of timing for corn silage harvest, usually 42-47 days after silking. Sweet corn remains in the milk stage for a relatively short period, so check the ears frequently.
According to the website for the Food and Agricultural Organization of the United Nations, these devices are built of rows of three to six conveyors that harvest corn still on the stalk, strip the corn of its unusable components and spit them out through a cleaning sieve.
Start by harvesting ears where silk appears that day. When planning harvesting operations, keep in mind the length of time required to harvest the field. Corn is harvested at a Georgetown farm. He spends 10 hours a day there this time of year, harvesting thousands of pounds of corn across hundreds of acres, all while taking business calls over the cab's speakers.
