Bolding within each test denotes entries with yields equal to the highest yielding entry based on Fisher's protected LSD (P = 0.10). Planted: May 16, 1997. Harvested: Maturity Group V - October 9, 1997. Maturity Group VI - December 19, 1997. Maturity Groups VII & VIII - December 19, 1997. Seeding Rate: Eight viable seeds per foot in 30" rows. Soil Type: Tifton loamy sand. Soil Test: P = High, K = Medium, pH = 6.6. Fertilization: Preplant: 15 lb N, 45 lb P205, and 90 lb K20/acre. Previous Crop: Corn. Management: Moldboard plowed, bedded, subsoiled and rototilled; Treflan, Basagran, Poast and two cultivations used for weed control; Diaznon, Dipel and Dimilin used for insect control; irrigation 8.0 inches. Test conducted by A. E. Coy and M. Pippin.
