Rapid, uniform germination and emergence of corn help set the stage for maximum grain yield at the end of the season.
Successful stand establishment of a corn crop relies on many factors, including the successful emergence of the seedlings in the first place.
Night time and early morning temperatures across Indiana dipped to lows (less than 28oF) on Wednesday and Thursday that may be concerning to alfalfa producers. Damage may be little to none, or possibly severe. Minimal damage may appear as new leaves emerging next week being bleached. Whereas, severe damage will have the plant losing its upright integrity and appearing water soaked (mushy). New seedlings will take on a water soaked appearance if freeze damaged. Variation in response could be extreme across a field due to differences in temperature because of topography. Older stands that were well managed last year will have a greater chance of survival. Please contact me at johnsonk@purdue.edu if damage is severe because of the freeze events.
While the coffeeshop rumor mills were active this past week with talk of “a lot” of corn planting going in areas of the state, in reality very little planting actually occurred (USDA Weekly Crop Progress, 13 Apr 2020).
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.
Taking large round and large rectangular bales and wrapping them with white plastic to make bale silage (baleage) has become a common practice.
The short answer to the question posed by the title of this article is: “Whenever you want to begin planting corn.”
Some of these challenges include severely delayed planting of hemp (and most other crops), labor shortages for some growers, “hot” hemp crops (THC > 0.3%), and harvested hemp left in barns and warehouses while some of the larger hemp processing companies filed for bankruptcy.
Seed corn represents the single most expensive variable input cost for Indiana corn growers (Langemeier et al., 2019) and so choosing the most economical seeding rate is important for maximizing that dollar return to seed at harvest time.
