| Abstract | ||||
| Two field experiments were carried out during the agricultural successive seasons (2020/2021 and 2021/2022) in the Agric., Farm of Assiut Univ., Egypt. This investigation aimed to study the effect of spraying methods on two faba bean varieties with different concentrations of salicylic acid (SA) and zinc on the growth and yield. The experiment was designed in split split plot design with three replicates. The first factor included faba bean varieties (Giza 843 and Giza 40) while the second factor included spraying with three concentrations of salicylic acid (0, 100 and 200 ppm. The third factor included two zinc application methods: soil application as Zinc sulphate at a rate of (5 kg/fed) at soil preparing, and foliar application at a rate of 50 mg Zn L-1 of EDTA (13%). Statistical results revealed that Giza 843 variety appeared to be preferred over Giza 40 in all growth and yield parameters. The obtained data indicated that growth and yield parameters increased significantly by increasing SA concentration from 100 ppm to 200 ppm in comparison to the control treatments in both seasons. Data also revealed that both zinc applications methods had a significant effect on growth and yield of faba bean as compared with the control. Also, spraying bean plants by 50 ppm zinc (EDTA) gave the maximum values of growth and yield parameters compared to soil addition with zinc sulphate. The study concluded that the combined foliar application of 200 ppm SA and 50 ppm zinc spray recorded the maximum growth and yield of Giza 843 variety under the conditions of Assiut Governorate. | ||||
