The data represent the means from eight replicate flasks (each containing three cucumber plants) per treatment. Means within the same column followed by different superscript capital letters are significantly different (P ≤ 0.05) according to Fisher's protected LSD test. The experiment was repeated once with similar results. P. fluorescens strains were added at 107 CFU per g of natural soil contained within 200-ml flasks (60 g of soil per flask), after planting three 90-h-old, sterile-grown cucumber seedlings per flask. P. ultimum was added (+) or not added (-) as a millet-seed inoculum to soil before planting. Plants were harvested after 7 days.
