2023 Abstract - IRRIGATION MANAGEMENT FOR CORN PRODUCTION IN THE SOUTHEAST: Due to water being so critical in corn production, low water holding capacity of soils, sporadic drought, non-irrigated acreage is low in Georgia. Typically, sensors and scheduling aids produce some of the highest yields, and Water Use Efficiency. Checkbook methods are typically the most used methods by growers. Adoption of more advanced irrigation scheduling systems is low due to cost, complexity, and uncertainty in expected economic benefit. Growers tend of over-irrigate corn as an insurance policy to prevent yield loss, however, it should be noted that even if yield is not reduced, can be reduced by over-irrigating the crop needlessly.
