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.
It's harvest time and that means farmers all over the Midwest are bringing in billions of bushels of corn. Corn, in general, is classified as sweet, pop, flour, silage or feed corn, depending on the type of carbohydrate stored in the ear. Corn plants thrive in brilliant sunlight and moist soil and adore loamy, fertile (and I mean fertile) soil.
Considerations include moisture content, forage harvester set-up, storage capacity, and potential impacts of starch digestibility on milk production. The ‘too wet' situation is a harvest timing and storage issue; too dry is more of a harvesting issue. Nationally, the sweet corn crop is worth $750 million to $850 million per year.
Hold the stalk of the corn plant at a point just above the ear in one hand. Sweet corn is wind-pollinated, so it should be planted in blocks, rather than in single rows. Smut spores can survive in the soil for two years. Growers need to ensure the corn crop is at the optimal silage maturity and moisture level before the silage harvest crew hits the field and the silage is harvested.
The high-moisture corn is used to feed cattle in the McNally's dairy operation, but it dries out the longer it stays in the field. In addition, earlage produced from corn with lower grain yields also will be lower in energy. PROCESS: Process all but very large amounts of seed by gripping dried ears by hand and twisting allowing kernels to fall into container.
Harvest needs to be slow, as little as 1.5 mph, and the stalks and clumps of dirt will be hard on the combine and may cause it to plug. When should you start harvesting corn? How to Grow: Plant these grain (field) when the soil is at least 55 degrees, or when dogwood leaves are the size of squirrel's ears.
Prior to harvest prepare your equipment by checking filters, hoses, etc., sharpen knives and cutter bars, and the accuracy of the cutter head and the storage facilities (e.g., sight rails, lights if filling at night, etc.). All tractors used in corn silage harvesting should be equipped with a rollover protection structure (ROPS) and seat belt.
Since baby corn ears are harvested before pollination and also before sugar has been stored in the kernels, baby corn is too underdeveloped to be sweet. Another option is to use an all-crop header on a forage harvester and take the upper one-third of the stalk along with all the ears.
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 How To Make Corn 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.
If you are also going to use the combine harvester available from the start, you will have to empty the harvester's grain tank for it to continue harvesting the corn. Figure 1 describes the moisture drydown patterns of two locations in the same field. I still have sweetcorn in the freezer from last year and I have just potted my first seeds for this year.
