Abstract:
The research aimed to test the effectiveness of inoculation with Plant growth-promoting rhizobacteria (PGPR) on some biochemical indicators of the Emerald F1 eggplant hybrid. The research was carried out in Lattakia countryside (Al Maghrit village) during the spring season for the two agricultural seasons 2021 and 2022. The study included four treatments: control, un-inoculated plants (T1), plants inoculated with a suspension of the first bacterial fertilizer (T2), plants inoculated with a second suspension of bacterial fertilizer (T3), and plants inoculated with a suspension of the third bacterial fertilizer (mixed fertilization) (T4). In the implementation of the research, a randomized complete block design was adopted, with three replicates for one treatment, at a rate of (15) plants in one replicate. The study showed that the best results were achieved when inoculating with a bacterial suspension from the third fertilizer (mixed fertilizer), where the plants vaccinated with this suspension were significantly superior to the rest of the treatments (plants vaccinated with a suspension from the first and second fertilizer) in the leaf content of essential nutrients (N, P, K). And in their total chlorophyll content, The plants inoculated with this suspension recorded the highest values for nitrogen (39.7 mg/g dry weight), phosphorus (6.88 mg/g dry weight), potassium (235.4 mg/g dry weight), and total chlorophyll content (3.3 mg/g fresh weight).The results also showed that the pollination of bacterial suspension from this (mixed) fertilizer affected the quality of the fruits, as it recorded the highest values in dry matter content (8.6%), total soluble solids (5.48%), protein (1.27%), and fiber (0.93%) vs. 6.8%, 4.1%, 0.86%, and 0.69%, respectively, in the fruits of control plants.
Keywords: eggplant, Solanum melongena L., Plant growth-promoting rhizobacteria, biochemical indicators.
