Abstract

The aim of conducted studies was to assess the effect of the application of Effective Microorganisms (EM) on changes in contents of available and readily soluble forms of nutrients in the peat substrate as well as growth, development and yielding of rose (Rosa x hybrida) and gerbera (Gerbera jamesonii) grown on the substrate. Effective Microorganisms were applied before the vegetation season in the form inoculum at 3 g preparation·5 dm substrate and in foliar application as plant spraying (repeated three times, with an aqueous solution at a concentration of 0.1%). In the conducted studies the effect of EM, applied both to the roots and as foliar application, was found on changes in contents of available nutrients in the substrate, at the simultaneous substrate acidification, in relation to the control combination. The significantly highest yield of flowers in case of both examined species was recorded at the application of the EM inoculum to the roots. This had a positive effect on the number or formed shoots and the diameter of flowers (in case of roses) and the number of formed inflorescences (in case of gerberas). Foliar application of Effective Microorganisms had a positive effect on the diameter of flowers in roses and the number of formed inflorescences and the number of leaves in case of gerberas. Results of conducted analyses indicate that Effective Microorganisms may be useful in the cultivation of roses and gerberas, due to their positive and at the same time significant effect on growth and yielding of these plants.
