Wheat (Triticum aestivum), one of the major crops in the world, is affected by different stresses that are partially overcome by the use of agrochemicals. New strategies with low environmental impact are rising, such as the utilization of plant growth promoting rhizobacteria (PGPR). The aim of the present work was to determine PGPR ability of six new Bacillus strains over wheat crop grown under field conditions. Mercurio Klein seeds were inoculated with a Bacillus suspension (potato-dextrose medium, ON, adjusted at DO=1) or a dilution of the culture media as control, and then sown in a plot, using one sowing line of 2m per treatment separated by 17cm from each other. Growth and yield related parameters were determined on different days after sowing (DAS). The plants developed from seeds inoculated with Bacillus sp. and B. megaterium showed a higher number of tillers at 70 DAS than control (6,2±2,7 5,5±1,9 5,3±2,2 vs 3,4±1,1 respectively, media±SE, p
