This study was conducted at Van Yuzuncu Yil University's Department of Horticulture to evaluate the effects of various PGPR (Plant Growth-Promoting Rhizobacteria) isolates on three lettuce varieties under field and greenhouse conditions. The varieties included Great, Kıvırcık, Iceberg for field conditions, and Chianti, Defne, Bombolo for greenhouse conditions. PGPR isolates used were Control, FZB42 (Bacillus amyloliquefaciens), CC44 (Pseudomonas fluorescens), and CC37/2 (Pantoea agglomerans). Field trials showed Iceberg had the largest head diameter (11.48 cm), and Great had the highest head weight (452.91 g). In greenhouse trials, Bombolo had the largest head diameter (10.91 cm), and CC44 led to the highest head weight (125.22 g). Kıvırcık yielded the highest leaf number in the field, while Bombolo excelled in greenhouse conditions. Although PGPR isolates had limited effects on leaf number, they significantly influenced head diameter and weight, especially in field trials. Variety differences were crucial, with PGPR effects varying based on environmental conditions. Additionally, pH levels were significantly impacted, with Great recording the highest leaf pH in the field and Chianti in the greenhouse. These findings suggest that selecting appropriate PGPR strains and optimizing environmental factors can enhance lettuce yield and quality. Future research should focus on broader field trials and the integration of PGPR with reduced chemical fertilizers for sustainable lettuce production.
