2024 Abstract - IRRIGATION SESSION - ESTIMATED SAVINGS WHEN USING REMOTE PUMP SHUFOFF FOR 30-, 60- AND 90-WELL FARM OPERATIONS: Estimates of labor, energy and water savings associated with remotely operated pump-shutoff systems will be presented. Different break-even cost scenarios of current pump automation technology will also be discussed. 2024 Abstract - ROUNDTABLE SESSION - REDUCING GREENHOUSE GAS EMISSIONS IN IRRIGATED RICE USING HYBRID CULTIVARS: Paddy rice has the highest global warming potential (GWP) among the major cereal crops. Field studies were conducted to determine the potential of hybrid rice cultivars to reduce GHG emissions in drill seeded rice systems under Furrow irrigation (RR) and conventional flooding (CF). Seasonal CH4 emissions decreased by ca. 80% in RR compared to CF irrigation with the greatest reduction in RT7521FP. GWP values decreased by ca.77% in RR relative to CF. This study shows that high yielding hybrid rice and RR irrigation can mitigate greenhouse gas emissions while sustaining rice grain yields.
