Effect of Starter Composition and Placement on Cotton in Georgia

Steven C. Hodges and Shelby Baker


A variety of starter materials and methods of application were studied to determine response of cotton under Georgia conditions. Treatments included 2x2 placement, 3 in sprayed bands using both NP and N only combinations, and a wide band of N only. In addition, plots with and without cotoran or aldicarb were compared with and without starters. Starters did result in significant yield increases for several materials and methods on a Tifton soil testing high in P. Responses included increased height at first square and lint yield. Stand counts were not affected by starter treatments. Although 2x2 placement methods have been most consistent in providing yield increases, the differences are usually not significantly greater than three inch sprayed bands. Wide band application of N failed to provide yield responses in either year, although it continues to be one of the most commonly practiced methods of placement used in Georgia. There was no significant difference between comparable plots with and without fluometuron or aldicarb.
