Article Summary Dr. Dhillon collaborated with researchers from the University of Florida and The Ohio State University to use machine learning models and assess how soil water deficit and supplemental irrigation affect maize and soybean yields across Ohio counties. Their study found that supplemental irrigation of 50.8 mm per month during summer months significantly increased maize yields by an average of 598 kg/ha and reduced year-to-year yield variability for both soybean and maize crops, with the greatest benefits occurring during dry years and in southwest Ohio counties.
With Ohio experiencing severe drought conditions in recent years, including the most severe drought in a century in 2024, this research provides critical insights into which counties would benefit most from supplemental irrigation, and how frequently such interventions may be needed with changing rainfall patterns in the region.
