Fig. 4. Estimated relative yield per plant (Yp) as a function of percentage coefficient of variation for vegetative biomass (CV) for soybean cultivar A3901 (circles) and maize hybrid DK752 (squares). Values were estimated according to Eq. [4]. Average vegetative biomass per plant (Vp) was assumed to be 10 and 150 g plant^–1 for soybean and maize, respectively.
