The post-pollination scuttlebutt overheard in coffee shops throughout Indiana during late summer often revolves around the potential for severe stress that might reduce kernel set or kernel size in neighborhood cornfields.

Many professions must invest in tools specific to their trade to be successful. Besides the typical tools of wrenches, screwdrivers, chisels and hammers, what other items or gadgets would be helpful to be a successful forage producer?

I was asked to come to a field in early April many years ago by a young producer.
For many hemp growers, things have been calm in the field.
Environmental conditions that exist when forages are ready to be harvested influences the amount of hours that it takes to get to a safe baling moisture.
White-tailed deer (Odocoileus virginianus) are among the common mammal pests of field corn in Indiana.
The “notched leaf edge” symptom in corn is a curious genetic leaf “disorder” that appears in certain hybrid families during periods of rapid development.
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. What this means is that the photosynthate demands of the developing kernels will take precedence over that of much of the rest of the plant.
Field corn in Indiana typically enters the critical flowering stages of pollen shed and silk emergence sometime between late June to late July. Success or failure during this period of the corn plant’s life greatly influences the potential grain yield at harvest time.
The silks that emerge from the ear shoot are the functional stigmas of the female flowers of a corn plant. Each silk connects to an individual ovule (potential kernel). A given silk must be pollinated in order for the ovule to be fertilized and develop into a kernel. Up to 1000 ovules typically form per ear, even though typically only 400 to 600 actual kernels per ear survive until harvest.
