Nitrogen and P uptake by the plant at the 2-qt/A rate at the 6-leaf stage both increased significantly. Starter applied was a mixture of UAN and 10-34-0 (30 lbs N, 30 lbs P205/A). Soil was a Crete silty clay loam and was high in P. Maryland. A fluid starter containing N, P, and K placed 2 by 2 at planting included a mixture of carpramid (1 qt/A) in a corn experiment conducted in Maryland. The combination produced a yield increase of just over 12 bu/A. A second study evaluated 2 qts/A of the product in a sidedress application of UAN broadcast at the rate of 120 lbs/A of N when corn was at the 4- to 6-leaf stage. The combination produced a yield increase of approximately 5 bu/A. Wisconsin. Carpramid was used in combination with fluids in fall, starter, sidedress, and split starter/sidedress applications in trials conducted at two locations in Wisconsin. As can be seen in Figure 3, the starter-alone application at the Hancock site produced the highest yield increase of 17.6 bu/A. Soils were a Piano silt loam at Arlington and a Plainfield sand at Hancock.
