E-Mail URBANA, Ill. - Sweet corn growers and processors could be bringing in more profits by exploiting natural density tolerance traits in certain hybrids. That s according to 2019 research from USDA Agricultural Research Service (ARS) and University of Illinois scientists. But since root systems get smaller as plant density goes up, some in the industry are concerned about the risk of root lodging with greater sweet corn density. New research says those concerns are unjustified. Root lodging can certainly be a problem for sweet corn, but not because of plant density. What really matters is the specific hybrid and the environment, those major rainfall and wind events that set up conditions for root structural failure, says Marty Williams, USDA-ARS ecologist, affiliate professor in the Department of Crop Sciences at Illinois, and author on a new study in ....

Contact: Jessica Ryan WASHINGTON, April 13, 2021 For her outstanding contributions to research on crop responses to global climate change, Agricultural Research Service (ARS) scientist Lisa A. Ainsworth is the agency s Distinguished Senior Research Scientist of the Year for 2021. Ainsworth, research leader for the ARS Global Change and Photosynthesis Research Unit in Urbana, Illinois (Midwest Area), is one of many ARS researchers being honored for their scientific achievements. Ainsworth joined the Global Change and Photosynthesis Research Unit in 2004 as a plant molecular biologist and has served as research leader since 2019. Her research aimed to find solutions for challenges affecting food production and security. Her work influenced the direction of climate change impact assessment and adaptation for federal, non-governmental organization and philanthropic efforts. ....
E-Mail IMAGE: Maize experimental field plot fumigated with elevated ozone (green pipes). Maize leaf samples were collected from similar rings throughout the growing season, to understand the response in diverse maize lines. view more Credit: Ainsworth lab Although stratospheric ozone protects us by filtering out the sun s ultraviolet radiation, tropospheric ozone is a harmful pollutant. A new study has shown that ozone in the lower layers of the atmosphere decreases crop yields in maize and changes the types of chemicals that are found inside the leaves. Ozone is formed when nitrous oxide, released from industries and tail pipes of cars, is broken down by sunlight and chemically reacts to form ozone. Researchers at the University of Illinois Urbana-Champaign have been studying the effects of ozone pollution on crops for over 20 years at a unique facility where crops can be grown under real-world farm field conditions but with increased concentration ....
