Abstract: Container production of horticultural plants on alternative substrates is becoming popular. Agricultural producers choose this way of production due to the high cost of commercial substrates as well as their lack of accessibility on the market. When selecting an alternative substrate, care should be taken to have all the characteristics necessary for the unimpeded growth and development of plants (pH value, nutrients).

Our work is based on two years research of the possibilities and effectiveness of alternative substrates utilization – spent mushroom substrate (button mushroom – Agaricus bisporus) and impact on growth and development of roots and above-ground parts of seasonal flowers transplants. As an initial planting materials rooted cuttings Pelargonium peltatum L. and Pelargonium zonale L were used. Measurements of morphological parameters of growth and development of plants (plant height, number of leaves, buds, flowers and flower branches) were performed, as well as determination of fresh and dry weight of roots and above-ground parts of transplants.

Application of spent mushroom substrate (as alternative substrate) in the production of geraniums Pelargonium peltatum L. und Pelargonium zonale L. positively influenced growth and development of morphological parameters and the fresh and dry weight of roots and above-ground parts of treated plants compared to non-tretated plants during two growing seasons.
