This study was conducted to evaluate the potential effect of foliar spray with different doses of two bio-stimulants Chitosan (CS) and Royal Jelly (RJ) on growth and yield and quality of two garlic cultivars (Egaseed1 and Balady i.e(Egyptian) at two winter seasons of 2017/2018 and 2018/2019.Generally, the foliar spray of all tested bio-stimulates treatments considerably improves almost all plant growth traits of garlic cultivars which reflected on plants yield and quality. Data showed that spraying Ega1 plants with different doses of CS and RJ considerably increased total yield (TY) in both seasons as compared with control (13.39 and 14.64 tons). The highest values of TY were found in Ega1 plants treated with 0.1g/l RJ (15.29 and 15.80 tons) and 0.3g/l RJ (15.08 and 16.61 tons) at both seasons respectively. On the other side, there was clear increase in TY of Egy plants treated with different CS and RJ doses at both seasons as compared with control (7.57 and 8.69 tons, respectively). The highest values of TY were found in Egy. plants treated with 0.2g/L RJ (9.23 and 8.53 tons) at both seasons respectively as compared with all other treatments. As compared to control, foliar spray with CS and RJ reduced weight loss % and deterioration of bulbs during storage. In general, foliar application of chitosan (1000 and 1500 ppm) and Royal Jelly (0.2 and 0.3 g.L^-1) could be recommended to improve productivity, quality and storability of the two garlic cultivars grown under Minia Governorate conditions.
