SCREENING OF INDIGENOUS PLANT GROWTH-PROMOTING BACTERIAL STRAINS FOR ENHANCING GROWTH OF TOMATO.....

In Nigeria, the continued use of agrochemicals for tomato cultivation is linked to high costs and negative health and environmental consequences. The potential of indigenous soil bacteria as biofertilizers in tomato growth was studied in this study. From the rhizosphere, root tissue, and non-rhizosphere of three tomato cultivars (Roma Vf, Beske, and Ibadan local), bacteria were recovered and identified. In vitro and in a green house, isolates were tested for their ability to promote plant development. The 16S rRNA genes were used to identify bacterial isolates with enhanced growth-promoting capacity. In vitro tests for phosphate solubilisation, ammonia, hydrogen cyanide, and indole acetic acid synthesis, four isolates from the genera Bacillus, Pseudomonas, Klebsiella, and Citrobacter performed exceptionally well. After four weeks of sowing, the growth features (seedling height, stem girth, number of leaves, and leaf area) showed a substantial improvement (P 0.05), with Bacillus (24.7 cm, 1.3 cm, 25.3, 3.9 cm2) and Pseudomonas (22.7 cm, 1.2 cm, 24.0, 3.7 cm2) generating the highest effect. As a result, more research into other qualifying parameters is required.
