| Abstract | ||||
| Two field experiments were carried out at the Agriculture Research Station of Assiut Research Farm, Faculty of Agric., Assiut Univ., Egypt, for two winter seasons of 2021/2022 and 2022/2023. The aim of this study was to investigate the response of vegetative growth, yield components, and some seed Quality of faba bean (Vicia faba L.) cultivar “Giza 843", to soil application of humic acid and foliar application of chitosan (Ch). Humic acid was applied as soil application at four concentrations (0, 2, 4 and 6 kg/fed twice during growth period. Chitosan (Ch) was foliar applied at 0, 50,100,150 and 250 ppm) four times within growth period. The experiment was designed in split plot design. Humic acid was allocated in the main plot. Meanwhile, chitosan was applied to the sub plot. Results revealed that either humic acid or chitosan highly significantly affected all vegetative growth traits, yield components, and chemical seed quality. Also, combined application of humic acid at a rate of 6kg/fed combined with foliar application of chitosan at 250 ppm recorded the maximum results. | ||||
