A field experiments was carried out in the Research and Experimental Center of the Faculty of Agriculture
at Moshtohor, Benha University, Egypt, during 2021/2022 and 2022/2023 winter seasons to study the ridge
widths (50 cm, 60 cm and 70 cm) under 4 plant distributions (Single seed in a hill on one side, Single seed in a
hill on both sides, Double seeds in a hill on one side and Double seeds in a hill on both sides). A strip-plot
design with three replications was assigned to three ridge width rates, the Horizontal factor (A), and four plant
Distribution rates, the Vertical factor (B). The results gathered from the two seasons' combined analyses may be
stated up as follows:
Ridge widths 70 cm and Planting in Single seed in hill on both sides were the highest values of
Chlorophyll content index (SPAD value), plant height (cm), number of branches/ plant, Plant weight (g)/plant,
Pod length (cm) /plant, Number of pods/plant, Weight of pods/plant (g), Number of seed/plant, Seed yield/plant
(g), Harvest index (%), Weight of 100-seed (g), Biological yield/fed (kg), Seed yield/fed (kg), Seed nitrogen
content (%), Seed phosphorus content (%) ,Seed potassium content (%) and reduced of Shedding in the flowers.
In general, it can be said that, given the circumstances of the current study, ridge widths of 70 cm planted
with a single seed in the hill on both sides may be the suggested treatment to increase the productivity of the faba bean crop.
