Sažetak

The effect of plant growth promoting rhizobacteria such as Azotobacter, Bacillus and Pseudomonas was tested separately or in combination in Catharanthus roseus for two consecutive years (2005 and 2006). The combinations of above mentioned PGPR strains significantly increased plant height, root length, root girth and alkaloid content in C. roseus in comparison to the control. In addition, all nutrient contents (N, P, K, Ca and Mg) were also significantly increased as compared to the control. The maximum N, P, K content was obtained from the combination of PGPR treatment. The results of this study suggest that PGPR applied in combination have the potential to increase the plant growth, alkaloid content and nutrient content of C. roseus.
