Quite a few farmers throughout the northern half of Indiana are frustrated with the slow drydown of the 2023 corn crop, especially since some grain elevators are refusing to accept grain deliveries with moistures above certain levels, e.g., 27%.

The cost of seed corn represents 17% of farmers’ variable cost of production, second only to the cost of nitrogen (N) fertilizer.
Among a number of corny oddities that appear from time to time is one that falls into the “kernel disorder” category.
The number of harvestable kernels per ear is an important contributor to the grain yield potential of a corn plant.
Excessive drying of the upper soil profile is conducive for the development of what some of us affectionately call the “rootless corn” or “floppy corn” syndrome.
Successful emergence (fast & uniform), while important, does not guarantee successful stand establishment in corn.
Early planted corn always involves the risk of cold weather in the weeks after planting.
Historical yield trends offer a glimpse into the future.
Corn grain yields in the U.S. have steadily increased since the late 1930’s.
This summary is based on 55 field scale research trials conducted at Purdue Ag. Centers and with on-farm collaborators around the state of Indiana from 2014 – 2022.
