Silage Corn and Nitrogen

摘要

Urbana-Champaign, Illinois (January 15, 2009)--Acres of Illinois corn harvested as corn silage in 2006 were 105,000 according to the Illinois Agricultural Statistics. Growers of corn silage have asked questions regarding the rate of nitrogen fertilizer for the crop. Considerable data from Illinois exists on the effect of nitrogen on the yield of corn grain, but there is limited data on the effect on corn silage. With this in mind, a four year (2005-2008) study was conducted at the Northern Illinois Agronomy Research Center, Shabbona to measure the effect of nitrogen on the yield and quality of corn silage.
