Successful germination alone does not guarantee successful emergence of a corn crop. Elongation of the mesocotyl must elevate the coleoptile to the soil surface before the inner true leaves emerge from the protective tissue of the coleoptile.

The short answer to the question posed by the title of this article is: “Whenever you want to begin planting corn.”
Seems like every year some fellow walks into the Chat ‘n Chew Cafe carrying an odd-looking tassel that is part tassel and part ear to show off to the guys over at the corner table.
Corn is often harvested at grain moisture contents higher than the 15% moisture typically desired by grain buyers.
Droopy ears are cute on certain breeds of dogs, but droopy ears on corn plants prior to physiological maturity are a signal that grain fill has slowed or halted.
Given the near record late planting of the 2019 Indiana corn crop and the continuing agony of delayed development of the crop, much of the coffeeshop talk down at Cecil’s Corner Cafe in recent weeks has centered on the risk of the late crop not maturing before a light frost damages the crop or an outright lethal freeze (28F) kills the crop.
Recently there have been numerous reports of swarms of “bee-like” flies around Indiana fields, farmsteads, and rural environments, and wanted to take the opportunity to tell you a bit about this curiosity. Adult hover flies (aka syrphid flies) can sometimes be mistaken for bees or wasps, because they look a lot like them! Some people refer to hover flies as “corn flies” or “sweat bees,” but these insects are actually quite different from bees. Hover flies belong to the Order Diptera, or the true flies. The most noticeable group at this time of year belong to the genus Toxomerus, which feed on pollen. There are many other syrphid flies present throughout the season that are beneficial, as their larvae feed on soft-bodied insects like aphids. Compared to sweat bees, hover flies have black and yellow markings, are able to fly in place yet dart away quickly, have a[Read More…]
Fancy colored yield maps are fine for verifying grain yields at the end of the harvest season, but bragging rights for the highest corn yields are established earlier than that down at the Main Street Cafe, on the corner of 5th and Earl.
The grain fill period begins with successful pollination and initiation of kernel development, and ends approximately 60 days later when the kernels are physiologically mature. During grain fill, the developing kernels are the primary sink for concurrent photosynthate produced by the corn plant.
Yield potential in corn is influenced at several stages of growth and development.
