To determine the rhizosphere effect when gathering plants,
the following medium samples were taken: a) closely adhering
to the roots (R1), b) remaining on the roots (R2),
c) non-rhizosphere (NR).
The statistical evaluation of the results consisted of
analysis of variance to determine the effect of compost
addition to the medium on the rooting of geranium cuttings
and on the development of microflora with reference
to a rhizosphere effect.
