Agron. colomb. [online]. 2017, vol.35, n.2, pp.232-237. ISSN 0120-9965.  https://doi.org/10.15446/agron.colomb.v35n2.63155.

Rosemary production (Rosmarinus officinalis L.) in Colombia is destined mainly for international markets (2.898 t in 2006), Although the national demand is low, this is a promising crop in some areas of the country, having potential to enhance producers life quality through the implementation of sustainable crops allowing the decrease of non-beneficial conditions in agriculture labors. Studying the response to the application of biofertilizers as an alternative to implement rosemary organic crops has become an important tool for the integrated crop management. In this research three commercial biofertilizer applied to the soil were evaluated (Azotobacter chroococcum, Pseudomonas fluorescens, humic and fulvic acids) facing a control treatment, significant differences were found regarding the number of stems growth per plant, however variables as oil extract volume and plant height did not present significant differences when compared with control treatment.

Palabras clave : biofertilizer; PGPR bacteria; nutrient solubilisation.
