Interpretive Summary:

Technical Abstract: In semi-arid environments, irrigation is necessary to stabilize maize production, but as a result of aquifer depletion in the Texas High Plains, producers are increasingly employing limited irrigation strategies. Variable precipitation and limited irrigation often result in water stress, which is magnified by cultivar selection and elevated planting populations. Under water stressed conditions, plant susceptibility to insect pressure and Fusarium verticillioides ear rot increases. However, most research studies evaluating cultivar and irrigation responses attribute yield losses and gains to cultivar x irrigation interactions. Field observations under water stressed conditions prompted the need to consider the influence of lepidoptera insect pressure on maize performance under water stressed conditions.
