While everything may not always be bigger in Texas, there are a few west Texas cotton farmers who have invested in sub-surface drip irrigation (SDI) and gained impressive yield increases. "Some Texas producers are reducing year-to-year yield variability with SDI, especially in water-limited areas where an arid environment is the norm," says Ed Barnes, director of agricultural research for Cotton Incorporated in Gary, N.C. After hearing of this success, cotton farmers in some not-so-arid regions of the Cotton Belt are considering SDI as a way to bump up their yields. To address these concerns, Cotton Incorporated has sponsored research projects to deliver advice for producers in the Mid-South and the Southeast. Six of the eight projects are funded by Cotton Incorporated, and the other two are funded by the Georgia and Alabama Cotton Commissions.
