A field experiment was conducted during two successive seasons 2019-2020 and 2020-2021 in The Experimental Farm of the Faculty of Environmental Agricultural Sciences, Arish University, North Sinai, Egypt. The aim was studying the effect of the combination between faba bean and onion plants intercropping and planting distances. Faba bean cv. was “LUS DE OTO" (Spanish), while onion cv. was "Shamah", planting distances for the faba bean seeds were 25, 30, and 40. The planting distances for onion seedlings were 10, 12, and 8 cm. Every five rows of onion were with one row of faba bean with a distance of 20 cm. Accordingly, faba bean seeds were sown and onion seedlings were transplanted by hand on the second week of October and middle of December, respectively in both seasons. The drip irrigation system was used in this experiment. The experiment was designed in a randomized complete block design, in three replications.  The results showed that a wide distance of 40 cm for bean plants and a narrow distance of 8 cm for onion seedlings recorded the highest values for vegetative growth characteristics i.e., root length, plant height, number of leaves, number of branches/plant and both fresh and dry weight of bean plants and, plant height, leaf length as well as number of leaves/plant of onion plants at 90 and 120 days after planting. While the green pod yield /m² and yield bulbs g/m² were increased significantly by application of the intercropping system and narrow planting spaces for each faba bean (25 cm) and onion (8cm) plants. It could recommend intercropping with an increasing plant density of faba bean and onion plants under drip irrigation system, EL-Arish conditions, and similar regions to increase the yield.
