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. Corn is planted when the soil is warm enough to germinate the seeds but not so early that the young plants are likely to be damaged by frost. If the corn has not matured by the time a late-season frost hits, the plants and cobs can be damaged and result in the death of the plant or poor-tasting corn.
Each year the annual corn crop determines the price of the grain. Corn has earned a reputation for sucking the life out of soils. Research generally indicates combine efficiency is best (harvest losses are lowest) when corn grain moisture is about 20-22%. Give the corn more time to dry if the kernels are soft and your fingernail leaves an indentation.
Sweet corn is harvested at what would be considered very early in the season for a farmer like me. The plant is still pretty green and the kernels are of course juicy and sweet. Some people prefer corn that's less sweet, with more texture in each kernel. Using the Corn Harvest Pans in the field didn't necessitate any change to a combine's ground speed.
Monitor losses behind the combine and grain quality in the grain tank throughout the day. Grow sweetcorn in a sheltered, sunny position, protected from strong wind, on any fertile garden soil. Sweet corn varieties lose their sweetness soon after harvesting. Gathering loss includes ears missed or lost by the machine, kernels shelled and lost by the stalk rolls or cornhead, which is where most harvest loss occurs.
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 Corn On The Cob 50%) corn stover removal improved corn yields by about 5.2 bushels per acre in more than 90% of the fields studied.
Ready-grown plants will establish quickly and provide cobs earlier than sowing seed directly into the soil. Grain moisture content showed a decrease from the Oct. That's why the long, crisp, sunny days of early fall produce the sweetest corn. This information combined with average whole plant dry-down rates can be used to roughly predict the proper time to harvest corn silage.
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.
When harvesting, break the shank (stem of the ear) close to the ear without breaking the main stock or tearing the shank from the stalk. To harvest baby corn at the perfect time takes practice. The black layer” is an abscission layer that effectively cuts off moisture and nutrient transfer between the plant and the grain.
Poorly packed, low-DM corn silage will have an extended plant cell respiration, resulting in an increased loss of digestible nutrients. The dried out plants are dead and do not produce seeds (they do on PC now so we'll possibly see it in an update) seeds are obtained via loot or the green still living corn plants.
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.
