Management of Inoculation with Bradyrhizobium japonicum and Application of Vitamins for Hydroponic Soybean Cultivation

Figure 6

Analysis of canonical variables among growth variables: plant height (PH), number of leaves (NL), stem diameter (SD); photosynthesis variables: water use efficiency (WUE), relative chlorophyll index (RCI), transpiration (E), intracellular CO₂ concentration (Ci), stomatal conductance (gs), and CO₂ assimilation rate (An); grain yield and its components: number of grains per plant (NGP), number of pods per plant (NP), 100-grain weight (HUN), and grain yield per plant (Yld) according to the application of vitamins and seed inoculation. Treatment s = C (control); N (niacin); T (thiamine), and NT (niacin + thiamine); WO (without inoculation); and WI (with inoculation).
