Fig. 2. Relationship between grain yield per plant (Yp) and percentage coefficient of variation (CV) for vegetative biomass per plant (Vp) in (A) soybean and (B) maize. Control (circles), temporal nonuniformity (squares), spatial nonuniformity (triangles), and temporal and spatial nonuniformity (diamonds) treatments are indicated. Data are from Exp. 1, 2, and 3 for maize and Exp. 4 for soybean. Each point represents one experimental unit. For soybean: y = 0.007x + 10.7 (r = 0.045; ns); for maize, y = 0.68x + 165.9 (r = 0.53 p < 0.01). Plant densities were 40 and 8 plants m2 for soybean and maize, respectively.
