Grain yield, shoot dry weight, and total water used in maize, sorghum, and pearl millet grown in different soil types in lysimeters in the field under well-watered conditions. (A, C) Experiment 3 with relatively high vapor pressure deficit (VPD) and (B, D) Experiment 4 with relatively low VPD (Fig. 1). (A) Grain yield, (B) shoot dry weight, and (C, D) total water used. Data are means (±SE) of three genotypes in each species (Table 1), with five replicate plants being sampled to determine a mean value for each genotype. Bars indicating the LSD at P<0.01 between the soil treatments within a species are shown. The LSDs to compare differences between species within each soil are as follows: (A) 6.6 g plant⁻¹, (B) 9.0 g plant⁻¹, (C) 1.8 L plant⁻¹, and (D) 2.1 L plant⁻¹.
