Abstract

Tomato (Lycopersicon esculentum Mill.) cultivation in Mali is confronted with multiple constraints of various kinds that greatly reduce yields. These include nutrient deficiencies (N, K, and P) in agricultural soils, inadequate supply of nutrients, and multiple insect and disease damage that can destroy up to 100% of production. A possible and proposed solution that has already proved its worth worldwide is the use of plant growth-promoting rhizobacteria (PGPR) to improve plant production. Phosphorus-solubilizing rhizosphere and endophytic bacteria were isolated from rhizosphere soils and tomato roots, selected for their ability to promote plant growth (PGP), and tested in a greenhouse on tomato plants. After the isolation and evaluation of these isolates in the laboratory, the best ones were selected. Tomato seeds inoculated with these selected isolates in the greenhouse showed their capacity to improve plant vigor, which implies an increase in germination as well as an improvement in vegetative and root development. These isolates also significantly increased the fruit weight of inoculated plants compared with non-inoculated control plants.

Key words: Plant growth-promoting rhizobacteria (PGPR), tomato, growth, production.
