Fig. 3. Effect of plant population on total number of main stem nodes per plant, Alexandria, LA, 2003. Plant populations are averaged across drill and hill-drop seeding configurations. The P value represents repeated measures analysis of total main-stem nodes; 33 975, 50 958, and 76 466 plants ha^–1 do not significantly differ and are significantly greater than 152 833 plants ha^–1 ( = 0.05).
