Potential of plant growth promoting rhizobacteria for enhancement of tomato growth
Abstract Plant growth‐promoting rhizobacteria (PGPR) associated with roots produce several biomolecules that stimulate plant growth. The study aimed to assess the potential of PGPR for tomato (Solanum lycopersicum L.) growth enhancement. Three PGPR isolates (Pseudomonas isolates PIA2 and PIA3, and B...

| description | Abstract Plant growth‐promoting rhizobacteria (PGPR) associated with roots produce several biomolecules that stimulate plant growth. The study aimed to assess the potential of PGPR for tomato (Solanum lycopersicum L.) growth enhancement. Three PGPR isolates (Pseudomonas isolates PIA2 and PIA3, and Bacillus isolate BIA1) were evaluated for growth promotion under greenhouse conditions. The experiment was conducted in three replications using Maya and Melkesalsa tomato varieties in a completely randomized design. Treatment with BIA1 resulted in the highest fresh weights of shoots (29.05 g) and roots (3.72 g) for the Maya variety (TC1) and 28.69 and 2.76 g for the Melkesalsa variety (TC2), respectively. Treatment with PIA2 showed maximum fresh weights of the shoots (25.05 g) and roots (3.26 g) for the TC2. Tomato plants treated with BIA1 and PIA2 exhibited significant increases in height, by 40.1% and 22.6% in the TC1 and 45.2% and 27.6% in the TC2, respectively. Besides, treatments with BIA1 and PIA2 in the TC1 increased the dry weight of shoots by 46.6% and 30.2% and that of roots by 73.3% and 68.7%, respectively. For the TC2, BIA1 and PIA2 isolates increased the dry weight of roots by 54.9% and 34.4% and that of roots by 68.1% and 48.9%, respectively. The results generally showed that BIA1 and PIA2 could be used to foster plant growth. Further study under field the conditions of BIA1 and PIA2 are highly recommended. |
