Abstract: 

The research aimed to evaluate the effectiveness of inoculation with “Rhizobium bacteria” and spraying the organic fertilizer “Savior” in stimulating plant growth and promoting the formation of root bacterial nodules. The study utilized the “Louze de Aunto” type of green beans. The research was conducted during the autumn season of the 2022 agricultural year in the village of “Raseon” in “Haffa” region, Latakia Governorate. The study involved six treatments: A control, (untreated plants), a treatment with “Rhizobium” inoculation, two treatments for spraying organic fertilizer at the degree of 2.5 and 5 cm3/L, and two treatments for Rhizobium inoculation, plus organic fertilizer spraying at the degree of 2.5 and 5 cm3/L, respectively. The research employed a complete randomized block design with three replicates for each treatment, with a rate of 15 plants per replicate. The results of the study indicated that the best outcomes were observed when inoculating with “Rhizobium” bacteria, in addition to spraying the organic fertilizer “Savior” at the degree of 2.5 cm3/L in all the assessed indicators. The treatment recorded the highest values in plant height 86 cm, average number of branches, 9 branches, number of plant leaves 89 leaves/plant, leaf area (15432.6 cm2, and its index 6.4. In the total chlorophyll content of the leaves (1.846)/g of fresh matter. Additionally, this treatment demonstrated an effective impact on the formation of root bacterial nodules, represented by an increase in the total number of root nodules 175 nodules/plant and effective nodules 116 nodules/plant.

Keywords: green beans (Vicia Faba L.), Savior organic fertilizer, Rhizobium Leguminosarum bacteria, vegetative growth, bacterial nodules.
