| Abstract | ||||
| Two field experiments were conducted at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt during2022/2023and 2023/2024 seasons to study the effect of foliar application with some growth stimulants on growth, chlorophyll content "Chl”, flowering and abscission as well as yield and its components and seed protein% of some faba bean cultivars. Each experiment included 24 treatments which were the combination of 4 faba bean cultivars (Sakha4, Nubaria5, Giza843 and Mariout2) and 6 foliar application treatments of growth stimulants substances (control, yeast, fulvic acid, seaweed, effective micro-organisms"EM1"and salicylic acid). The results can be summarized as follows: 1- There are significant differences among the tested faba bean cultivars in their growth, flowering, abscission% and seed yield and quality in favor of Mariout2 for plant height, leaf area/plant, total dry weight/plant, no. of flowers/plant, and flowers and total abscission/plant%, as well as straw yield/ fed,Giza843 for total Chl, no. of setting pods/ plant, setting pod abscission%, no. of pods/plant and seed yield/plant as well as seed and biological yields/fed,Nubaria5 for no. of leaves/plant, no. and weight of seeds/pod and 100-seed weight and Sakha4 for harvest index and protein%. 2- Spraying plants with any tested growth stimulants caused a significant increase in all studied characters but reduced the abscissions% of flower, setting pods and their total/plant compared to the control treatment. 3- Spraying Giza843cv. with yeast (2.5g/L) was the most effective interaction treatments for increasing Chl. content, no. of pods/plant, seed yield either per plant or per fed. The highest values of plant height and total dry weight/plant were obtained when Mariout2cv.was sprayed with EM1 (2cm3/L). The lowest total abscission/ plant% was scored by Sakha4 cv. sprayed with yeast (2.5g/L). | ||||
