Evaluating performance and feeding sustainability of corn genetic traits [XP2017-01]

Project Description: 

Iowa is a leading corn-producing state where corn stover is an important feedstock for cattle production. In recent years, farmers have been inquiring about the yield and grain composition performance of conventional corn hybrids compared to various transgenic hybrid options that are available. Additionally, cattle producers have been increasingly concerned about transgenic hybrids being less desirable, palatable and efficient as conventional hybrids. This type of information is hard to acquire due to the extremely limited number of hybrids that are commercially available as conventional and at varied levels of transgenic inclusion.  This project aims to generate information that will be used to guide crop and cattle production recommendations and add resiliency for sustainable integrated crop and cattle production operations. Using two genetic hybrids of corn in replicated plots, researchers will measure insect and disease severity, root and stalk lodging, grain moisture, yield and grain composition. They will also evaluate feedstock suitability and preference with varying levels of transgenic inclusion.

Mark Licht earned a bachelor of science degrees in agricultural extension education and agronomy from Iowa State University in 2000. He then became an ISU Extension and Outreach field specialist and served as field agronomist until 2014. He was appointed an Extension Cropping Systems Agronomist in 2014 and continues to serve in this position. In 2016, he added assistant professor to his job duties, dividing his time between Extension, research and teaching. Licht earned a master's in soil science, and a Ph.D. in crop production and physiology, both from Iowa State University.
