Application of post-consumer wood composts in canna lily cultivation (Canna x generalis L.H. Bailey)

Abstract

The purpose of the conducted experiment was to learn about the influence of com posts obtained from post-consumer wood on the growth, flowering and nutrition of the canna lily (Canna x generalis L.H. Bailey)‘Tropical Yellow’. The number of microorganisms and the level of their enzymatic activity in the media in which the plants were cultivated were also examined. Two variants of composts made from post-consumer wood, marked OPA and OPB were used in the experiment. Plants were cultivated in the media consisting of compost and high peat in different volumetric combinations. The content of macro- and microelements, the pH and salinity of particular media were the derivatives of compost and peat percentage in the medium. It was found that the medium type had a significant influence on the growth and flowering of the canna lily. The type of the compost used proved to be a determining factor in changes in the number and activity of the microorganisms in the examined media, as well as the nutritional status of the plants.
