Chapter 11, Problem 11.52(choose chapter or problem)
Four plots were available for an experiment to compare clover accumulation for four different sowing rates (Performance of Overdrilled Red Clover with Different Sowing Rates and Initial Grazing Managements, N. Zeal. J. Exp. Ag., 1984: 7181). Since the four plots had been grazed differently prior to the experiment and it was thought that this might affect clover accumulation, a randomized block experiment was used with all four sowing rates tried on a section of each plot. Use the given data to test the null hypothesis of no difference in true mean clover accumulation (kg DM/ha) for the different sowing rates. Sowing Rate (kg/ha) 3.6 6.6 10.2 13.5 1 1155 2255 3505 4632 2 123 406 564 416 Plot 3 68 416 662 379 4 62 75 362 564
