OverviewAI-generated summary
Jason Keith Norsworthy's research program focuses on weed science, herbicide resistance, and crop management, particularly within Arkansas agricultural systems. His work investigates the efficacy of various weed control strategies and the development of herbicide resistance in key weed species such as Palmer amaranth and red rice.
Norsworthy has published extensively on these topics, with a significant body of work addressing the confirmation and management of herbicide-resistant weeds. His research also explores the impacts of environmental factors, including temperature and drought, on crop and weed dynamics, and reviews potential adaptation strategies. He has also examined the status of herbicide-resistant rice technologies and their implications for weed management.
With an h-index of 50 and over 10,000 citations, Norsworthy is recognized as a highly cited researcher. He leads an active research group at the University of Arkansas at Fayetteville and has a history of collaboration with colleagues within the institution, including L. Tom Barber and Trenton L. Roberts.
