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.
The Purdue Crop Chat is a regular podcast from Hoosier Ag Today and the Purdue University Extension Service, featuring Purdue Extension soybean specialist Dr. Shaun Casteel and Extension Corn Specialist Dr. Dan Quinn.
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.
The key to maximizing corn yield is largely driven by minimizing the impact of potential yield-limiting factors during the growing season.
This week marks the first time that corn harvest progress has dropped below the 5-year average for 2021.
This report summarizes corn yield response to fertilizer nitrogen (N) rate in field-scale trials conducted
around the state of Indiana since 2006.
There are many factors that can contribute to stalk decline. There are both plant pathogenic causes and abiotic stresses factors that can play a role in reduced stalk integrity, such as drought and flooding. Either way, as stalk tissue becomes compromised below the main ear the stalk may become brittle or weak and be prone to lodging.
The majority of the corn across the state of Indiana has either just entered the dent growth stage (R5) or has already been in the dent stage as it approaches physiological maturity (R6, black layer).
The USDA recently released their first monthly crop report on August 12, which includes crop production data for the U.S., including estimates for 2021 area harvested, yield, and total production.
