The Effect of Planting Distances and Foliar Fertilization with Zinc on the Vegetative Growth Characteristics of Soybean Crop

Abstract To investigate the impact of planting distance and zinc foliar fertilization on soybean growth, a field experiment was conducted in summer 2022 at Hamidiyah research station College Agriculture University Anbar. The set up Split Plot R.C.B.D with three replicates. Four concentrations (0, 25, 50 75 mg Zn l −1 ), allocated to main plots, whereas distances (7, 14, 21, 28 cm) between plants were sub-plots which gave plant densities 190,000, 95555, 63333 47777 ha , respectively. significantly affected vegetative growth characteristics, as 7 cm (high density) outperformed height (116.11 first pod from soil surface (29.25 cm). While (low recorded highest average for number branches (8.67 branch leaf area (53.66 dm 2 −1) chlorophyll content leaves (5.29 g fresh weight), dry weight (410 ). With regards development, L solution most effective. Plant (106.78 cm), (5836 (5.06 gm Pod earth (30.46 best averages (455.8 plant’s above interacted concentration cm, while mean branches, area, content, found under same conditions.
