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.

Results from 97 field scale trials around Indiana since 2008 suggest that maximum yield response to plant populations for 30-inch row corn grown under minimal to moderate stress conditions occurs at about 32,150 PLANTS per acre (ppa), equal to seeding rates of about 33,840 SEEDS per acre (spa).
Sulfur (S) deficiency is becoming more common in Indiana crops because S emissions from coal-fired power plants have decreased over the past few decades and, thus, so has atmospheric S deposition.
The Purdue Crop Performance Program (PCPP) annual Corn and Soybean Performance Trial Bulletin was recently posted online.
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.
Delayed maturity of corn due to late planting or simply cool growing seasons often translates into delayed or slow drydown of mature corn grain prior to harvest and, consequently, higher than desired grain moisture contents at harvest. Wetter grain at harvest increases the need for artificially drying the grain after harvest which, in turn, increases the growers’ production costs and can delay the progress of harvest itself.
Soybeans in Indiana often show potassium (K) deficiency symptoms during seed fill – leaf margin chlorosis to necrosis.
Corn is often harvested at grain moisture contents higher than the 15% moisture typically desired by grain buyers.
Highlighter green soybeans (N-deficient) are related to the root system, number of nodules, and nodule activity (i.e., evidence of N fixation).
Understand this one simple fact about grain yield monitors: They do not measure grain yield.
