Harvesting corn is a matter of picking the ears at peak flavor. Yet, it's very likely that in this example you would lose more than 10+ bushel to the acre by letting the corn dry out in the field. The drying rate is usually faster when grain moisture is high and slows as it dries and the disparity with the environment diminishes.
Earlage is ensiled corn grain, cobs and, in some cases, husks and a portion of the stalk (depends on the harvest method). Now, choose a kernel that's a few down from the top of the ear because those teeny top ones sometimes never fill out; so you could be fooled.
Grain quality, good or bad, largely results from cumulative grower decisions and practices from the field to the bin. Corn smut will turn kernels gray or black and cause kernels to swell. Pull up the corn stalks immediately after harvest. Strip back the husks on 5 plants in 5 areas of the field to check for insect feeding or ear rots.
For example, if a given field measures 30% dry matter at the early sampling date, and the target harvest dry matter is 35%, then the field must gain an additional 5% units of dry matter, thus requiring an estimated 10 days (5% units divided by 0.5 unit change per day).
The whole-plant % DM information combined with average whole-plant drydown rates can be used to roughly predict the proper time to harvest silage. Geo-graphic location, planting date, hybrid selection, and weather conditions affect the relationship between kernel milk-line position and whole-plant DM content.
Snaplage: This term describes ensiled corn grain, cobs and husks typically harvested with a forage harvester equipped with a corn snapper header so that only the ear and a portion of the ear shank is removed, chopped and ensiled (Figure 2). At harvest, cob material will be higher in moisture than grain.
This Crop Insights discusses factors important to corn grain quality in the field, during combining and in drying. These kernels are seeds that each contain a natural food-storage compartment as well as the corn embryo. The quality of the sweet corn will be reduced if it is cross-pollinated by popcorn.
Note: You may choose to spray fertilizer on the planted corn—with the use of the appropriate Fertilizer Spreaders Using fertilizers usually offer twice the amount when stores buy the corn you've harvested. If 60 percent of the stover would be harvested, then harvested stover amounts would range from 1.8 to 2.7 DRY tons per acre depending on grain yield level.
Plants are less successful on dry or heavy soil. After much of the research I have done on sweet corn, I have found that a stalk Corn On The Cob will produce between one and two usable cobs, in the variety I am planting. Crop conditions, including non-grain crop moisture, can change rapidly during autumn days.
I've been growing Golden Harvest corn for about eight years. ‘Earlibird AGM:(Supersweet) Vigorous plants with good sized, uniform cobs. "That's why grain farming has been so viable on Delmarva for all these years," said Bounds. It is important to recognize the importance of harvesting corn silage at the correct moisture.
