The F-test indicated no statistical differences at the alpha = .10 probability level; therefore, an LSD value was not calculated. Bolding indicates entries yielding equal to highest yielding entry within a column based on Fisher's protected LSD (P = 0.10). Planted: April 3, 1997. Harvested: September 8, 1997. Population: 27,000 plants/acre in 30" rows. Soil Type: Cecil sandy clay loam. Soil Test: P = High, K = High, and pH = 6.5. Fertilization: 49 lb N, 98 lb P2O5, and 147 lb K2O/acre preplant and 200 lb N/acre applied as a sidedress. Previous Crop: Soybean. Management: Moldboard plowed and rototilled; Aatrex and Lasso used for weed control; irrigated 9 times totaling 6.0 inches. Test conducted by J. L. Day.
