2023 Abstract - SAVING WATER BY USING COVER CROPS AND NO-TILL IN COTTON: Reducing irrigation frequency and quantity can save time, money, and water. Cover crops with different tillage regimes were researched for their potential ability to reduce the need for supplemental irrigation water. Findings show soil moisture was higher with cover crops and no-till. Low soil moisture in conventionally treated cotton resulted in more irrigation events and greater water use. Lint yield, water use efficiency, and soil water relations during the 2021 and 2022 growing seasons will be discussed.
