Abstract: Two field experiments were carried out in the 2022 and 2023 growing summer seasons at the Experimental Farm, Faculty of Agriculture, Mansoura University, Dakahlia Governorate, Egypt, to enhance soybean productivity and seed quality through seed priming and biofertilization treatments under water stress conditions. Water stress circumstances include irrigation levels that are 100%, 80%, and 60% of the water duty (2818 m3/fed). Seed priming treatments were without, hydropriming, calcium chloride, humic acid and seaweed extract. Biofertilization treatments were without, inoculation with Rhizobium japonicum, Mycorrhiza and Rhizobium japonicum + Mycorrhiza. A separate experiment was conducted for each watering level. Each irrigation treatments was conducted in a separate experiment, every separate experiment laid-out in a strip-plot design with three replications. The highest values of soybean yields, their constituent parts, and seed quality were obtained with normal irrigation. Soybean seed priming in calcium chloride (CaCl2) at a rate of 6 g/L resulted in the highest yields, their constituent parts, and seed quality. Seed inoculation with Rhizobium japonicum besides Mycorrhiza exceeded other biofertilization treatments and produced the highest values of yields and its components as well as seed quality of soybean. To save irrigation water, while maintaining the highest productivity and seed quality, it could be recommended that irrigation of soybean plants at the level of 80 % from water duty (2254.4 m3/fed) and priming seed in CaCl2 at 6 g/L besides inoculating seeds with Rhizobium japonicum in addition to inoculation with Mycorrhiza under the environmental circumstances of Egypt's Dakahlia Governorate's Mansoura district.
