Evaluation of Germination and Seedling Growth of Plant Seeds Primed with Cultures of Providencia Sp. and Bacillus Cereus under Varying Conditions

Background: Seed quality, an important determinant of germination and vigor potential, can be improved through seed priming. This study was therefore aimed at assessing the effects steeping duration inoculum concentration on seedling growth five crops priming with growth-promoting rhizobacteria. Methods: Broth cultures bacterial strains, belonging to Providencia vermicola (2 strains), P. rettgeri Bacillus cereus (1 strain), isolated from rhizosphere were used for in study. Seeds cowpea ( Vigna unguiculata ), soybean Glycine max sorghum Sorghum bicolor sesame Sesamum indicum okra Abelmoschus esculentus ) as experimental materials. To determine duration, viable seeds respective primed broth isolates allowed stand a known (1, 2, 3, 4, or 5 h). Then, another set steeped varying concentrations period that determined optimal first experiment. Result: At expiration both experiments, final germination, mean time, index, index estimated. Generally, higher values restricted shorter periods soybean. With respect concentration, there no consistent pattern parameters. Conclusion: The revealed primacy over
