Every morning Pa went cheerfully whistling to the field… Now he carried a sack of corn fastened to his belt, and as he plowed he threw grains of corn into the furrow beside the plow's point. Finally, consider a "worst case" scenario at the same yield and price levels where excess harvest losses are 15% and down corn is as high as 30 percent moisture, the cost of harvest losses would be $123.75 per acre but only $79.37 would be needed to dry the crop, so even at this high moisture the savings would be $44.38 per acre.
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.
The plant is dying and drying right along with the kernels. Baby corn has fewer pest problems than full-sized ears of corn. These varieties are just as big as regular corn plants, but may have more ears per plant. After harvest, remove the husks and place the ears in mesh bags and hang in a warm, dry, well-ventilated location.
During wetter years, the drying rate will be slower. Fortunately, corn stalks do show signs that harvest time is near (or here). Lower volumes of corn residue remain following earlage harvest, and that which does remain is lower in nutritional quality for grazing compared with corn residue remaining after grain harvest.
Some farmers prefer sampling only 2 or 3 plants to reduce the chances of a non-representative grain to stover ratio. DuPont and Iowa State determined that partial (about 50%) corn stover removal improved corn yields by about 5.2 bushels per acre in more than 90% of the fields studied.
The approximate value of the nitrogen, phosphate, and potash per DRY ton of harvested corn stover is $2.72, $0.79, and $2.36 (based on $0.20, $0.22, and $0.12 per lb. of nitrogen, phosphate, and potash fertilizers), for total nutrient value of $5.87 per DRY ton.
Corn grain quality is increasingly important as more grain is used for processing and other specialty end uses. Some hybrids are designed only for use in silage and have less stay-green, so that the grain will have higher moisture relative to the whole plant.
Instead of harvesting them when the tassels turn brown, they will be left on the stalk weeks longer until the husks turn brown and dry as well. We know that kernel milk stage is not reliable for determining the actual harvest date, but it is a useful indicator of when to sample fields to measure plant dry matter.
Sampling fields is the best way to monitor plant maturity and harvest timing. Apparently, farmers who grow corn for seed corn production top off (cut off) as much as two feet of the stalk. For good pollination and wellfilled ears, plant in blocks at least 5 rows wide.
