In our preliminary studies (unpublished data) it has
been found that enrichment of a greenhouse medium
with pig slurry has a positive influence on the general
development of the geranium. The purpose of this work
was to state the influence of biofertilizer on the rooting
of geranium cuttings. The rate of the rooting of this plant
cuttings as well as the abundance of expanding root systems
are significantly regulated by phytohormones, which
besides plants, can also be produced by plant growth-promoting
bacteria occurring in their rhizosphere [11]. In
view of this, the effect of compost on the development of
microflora in the studied media has also been determined.
