Harvesting corn is a matter of picking the ears at peak flavor. 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.
The ears are a shoepeg” type, so kernels are packed in a zigzag pattern. Stalks are weak because dry weather late in the growing season caused the plants to transfer material from the stalks to the developing ears, he adds. With timely harvest, field losses can average 2 percent of the yield.
Selecting hybrids that excel in these traits is important to production of grain having dense, intact kernels with minimal breakage, disease and discoloration, especially for markets that pay a premium for high grain quality. If you want to remove the kernels from a lot of ears, it might be a good idea to wear gloves.
Once that is done, approach a corner of your field and drive along a straight line to begin harvesting. Whether you're removing the kernels before storage or just before popping, there's no real trick to it. Simply grasp the ear firmly in both hands and twist until the kernels drop out.
Corn can be stored on the ear in corn cribs, or shelled to remove the dried kernels from the cob before storage. 1. Clip or chop the corn plants into 2-5 cm (1-2 in) long pieces. Hybrids with lower stalk strength ratings exhibited greater stalk rot, lodging and yield loss when harvest was delayed.
Corn grows so quickly, that timely harvest is crucial. Corn earworms deposit eggs on developing silks; later the small caterpillars will follow the silks down into the ears, where they feed on the tips.

Once kernel milkline begins to move, measure moisture of fields intended to be harvested for silage (Table 1). Corn should be first sampled to measure dry matter shortly after full dent stage (80% kernel milk) for bunker silos and bags, at 60% kernel milk for conventional tower silos, and at 40% kernel milk for sealed (oxygen-limited) tower silos.
Once the target milk stage is reached and whole-plant % DM is determined, an average dry down rate of 0.5% unit per day can be used to estimate the number of days until harvest. Under drought conditions or south of the upper tier of states in the USA, samples should be collected slightly earlier than the stages shown in Table 2. Corn reaches harvestable % DM at earlier kernel stages as you move south.
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.
When kernel dry matter accumulation is complete several layers of cells near the tips of kernels in most hybrids turn black forming the "black layer". The number of ears you save will depend on how much corn you wish to plant next year. Sweet corn grows best on well-drained soils that have good water-holding characteristics.
