2023 Abstract - MANAGING FIELD VARIABILITY IN WEST TENNESSEE COTTON: Variability within and across West Tennessee cotton fields provides several management opportunities. While variable applications of lime, P and K have become quite common, only a few have adopted variable applications of N and plant growth regulators. Walker Farms produces cotton in Fayette County, TN on variable ground around Longtown Gin. Walker Farms tackles variability in cotton fields from a multi-faceted approach; over the years, they have managed within field variability with variable rate applications of lime, P, K, N and plant growth regulators, among other things. The Walkers also run overhead, row and subsurface drip on their operation. During this session, Mr. Bob Walker, Mr. William Walker, and Dr. Tyson Raper will discuss their experiences and research conducted on these topics.
