Fig. 8. Plots of means for shoot density and root plus rhizome mass during April of 2002 and 2003 on turfgrass plots in Connecticut. Treatments are date of fall fertilization: control (no fall fertilizer), 15 September, 15 October, 15 November, or 15 December. Error bars indicate standard error of the mean. Orthogonal contrasts from ANOVA indicate fall fertilized treatments greater than control for shoot density for each year (p = 0.034 for 2002 and p = 0.049 for 2003), with no differences among fall fertilized treatments. No differences were found among root mass means for either year.
