Cotton Response to Reduced Tillage Stale Seedbed Systems in North Mississippi

R.R. Dobbs, N.W. Buehring, and M.P. Harrison. Mississippi State University, P.O. Box 1690, Verona, MS 38879

A three-year (2003-2005) study was conducted on a Leeper silty clay loam soil. The no-till system was compared to reduced tillage stale seedbed systems of one pass operation [fall bed-roller or spring PrepmasterŪ (bed-renovator)] or a fall two-pass operation paratill (deep under-row tillage) followed by (Fb) bed-roller on soils with less than 0.5% slope. All cotton was planted no-till in late April of 2003 and 2004, and early May in 2005. The old beds for the no-till treatment were 1 to 2 inches tall at planting in 2003 and less than 1.0 inch in height in 2004 and 2005. The other treatments bed heights at planting all three years ranged from 4 to 6 inches tall. The 2005 data will be included in the presentation. The no-till treatment had lower plant population than all other reduced tillage treatments in 2003 but not in 2004. Both years, no-till showed less early season growth, less seed cotton and lint yield, and was shorter in height at harvest. The bed-roller, paratill + bed-roller applied in January 2003 and the fall of 2003, and the Prepmaster treatment applied in early April 2003 and 2004 showed no difference in yield and all produced more lint yield than the no-till system.
