This report summarizes corn yield response to fertilizer nitrogen (N) rate in field-scale trials conducted around the state of Indiana since 2006. These results are applicable to N management programs that use efficient methods and timings of N fertilizer application.
Frankly, today’s agricultural world is teeming with misinformation, half-truths, pseudo-data, bogus ideas, and sincere but incompetent researchers.
Sulfur (S) deficiency is becoming more common in Indiana crops because, in part, S deposition from coal-fired power plants has been reduced.
Seed corn represents one of the most expensive variable input costs for Indiana corn growers (Langemeier et al., 2021) and so choosing the most economical seeding rate is important for maximizing dollar return to seed at harvest time.
This presentation shares what we know and don’t know about corn response to applied sulfur fertilizer in Indiana, based on field scale research we conducted throughout the state from 2017 – 2021.
This report summarizes corn yield response to fertilizer nitrogen (N) rate in field-scale trials conducted
around the state of Indiana since 2006.
Among the top 10 most discussed (and cussed) topics at the Chat ‘n Chew Cafe during corn harvest season is the grain test weight being reported from corn fields in the neighborhood.
Serious crop stress during the grain filling period of corn increases the risk of stalk rots and stalk lodging (breakage) prior to grain harvest.
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
Historical trends of grain yield improvement offer us a glimpse of yields yet to come, although, like the stock markets, past performance is no guarantee of the future.
