Fluids in combination with carpramid have shown more consistent yield responses with winter wheat in Kansas. Applications with both fluid starters and with topdressed UAN have been effective. Studies across seven locations in central Kansas produced hard red winter wheat yield increases ranging from no significant responses to 19 bu/A, with most consistent responses occurring when the carpramid was applied with topdressed UAN. Average yields over the seven sites using different rates are shown in Figure 4. UAN was applied at 20 lbs/A of N. Soils at the sites were generally calcareous silt loams with organic matter content ranging from 1.1 to 1.3 percent. However, at some other locations responses were not significant. Maryland. Soft red winter wheat responses in 1997 studies were also good (Figure 5), although all studies did not report significant yield increases using the carpramid at varying rates with an NPKS liquid starter or topdressed UAN. Note the better response was the 2-qt/A rate in combination with topdressed UAN. Advancement in maturity by 3 to 4 days also has been observed--- important where double-cropped soybeans are to follow wheat. The UAN was banded on 10-inch centers. Cotton Louisiana. Fluid starter banded in combination with 2 qts/A of carpramid had a positive effect on uptake of N, P, and K, increasing lint yield significantly (Figure 6). Mississippi. A 4-qt/A rate in combination with a fluid fertilizer produced a 226-lb/A jump in lint yield at the Westfield Plantation near Lexington. In addition, approximately 15 percent more boils were open on September 9, emphasizing the effect of carpramid on advancing crop maturity.
