^These means are least square means. Diameters are adjusted for diameter at the 

 beginning of the study and heights are adjusted for height at the beginning of the 

 study. 



^Treatment 1 = no fertilizer, 2 = 200 lb N/acre, 3 = 400 lb N/acre. 

 ■^Different letters following means indicate significant differences (p < 0.2105) be- 

 tween treatments.
