Newer Hybrids Need Nitrogen Later in the Growing Season

Researchers with Iowa State University and Pioneer have studied nitrogen uptake in corn to better manage nitrogen.  They have found That hybrids developed since about 1990 take up more nitrogen later in the growing season.  The implication is that early applied nitrogen may be less than ideal for top yields.  It also looks like nitrification inhibitors may play a bigger role in nitrogen management.  High clearance equipment for sidedressing is also looking like a good nitrogen management tool.  Check the link above for more details.
