| Abstract | ||||
| This study was conducted at the Agronomy Experimental Farm, Faculty of Agriculture, Assiut University during the two growing seasons of 2020/2021 and 2021/2022 to investigate the response of faba bean seed yield and its components to foliar spray by various growth regulators. The experiment was carried out in randomized complete block design (RCBD) with three replications utilizing a strip plot configuration. The foliar sprays (Control, Indole Acetic Acid, Gibberellin Acid, and Salicylic Acid) were organized vertically, whereas the application times (one, two, and three times) were organized horizontally. In the two growing seasons, the evaluated growth regulators significantly influenced the number of branches plant-1, 100-seed weight, seed weight plant-1, and seed yield faddan-1 characteristics. Plants treated with 200 ppm Gibberellin or Salicylic Acid had the highest mean values of the specified attributes in both seasons. The results also demonstrated that the examined application timings had a highly significant impact on all analyzed features in both seasons. Furthermore, growth regulators were applied three times at 30, 60, and 90 days after sowing (DAS), yielding the greatest average values of seed yield faddan-1 (1365.64 and 1373.87 kg in the first and second seasons, respectively). | ||||
