The Iowa Corn Promotion Board (ICPB) funds research unlocking important innovations in plant productivity. Two key initiatives look to reduce the corn plants need for additionally applied nitrogen and help to identify key corn genetic traits that impact yield and the plant’s ability to respond to environmental stressors.
Nitrogen fertilizer has become more expensive in recent years adding significant cost to corn production. The Gulf Hypoxic Task Force and the Iowa Nutrient Reduction Strategy have called for a 45 percent reduction in fertilizer in the water.
Meeting future corn production challenges will require the development and management of crop varieties that will perform well in spite of increased weather variability. To address this challenge, an ambitious wide scale plant phenotyping initiative was initiated which will expand our understanding of the interacting roles of corn genetics and crop environments on crop performance. Iowa Corn continues to leverage the corn genome to gain understanding of how the corn plant works to improve our ability to get more productivity out of an acre of ground.
