Abstract
This research was conducted to determine the effects of plant growth-promoting rhizobacteria (PGPR) on plant growth, yield and nutrient content of soil and leaves in lettuce production.
The experiment was carried out in a plastic greenhouse of the Department of Horticulture at Ege University in İzmir, Türkiye from December 2023 to February 2024. Within the scope of this study, the mixture of Bacillus subtilis, Bacillus megaterium, Acinetobacter johnson, Acetobacter fabarum, Azospirillum brasilense, Nocardiopsis alba, Lactobacillus spp. was applied in two different ways namely dipping roots of seedlings before planting (DbP) and application to root zone at 14-day intervals (App14i). Plants with no application of PGPR constituted the control group (Cont). ‘Aveleda’ lettuce cultivar was planted into soil with a plant density of 5.33 plants m‑2. Bacteria consortium had a significant effect on the average head weight, total yield, root fresh weight and increased leaf nutrient contents.
It was concluded that PGPR can be applied multiple times during the season in order to improve plant growth, yield and nutrient uptake.
