Апстракт

The survey was conducted in order to determine the quality of the seedlings of Petunia x hybrida „Double pirouette purple“. It was produced and treated with different fertilizers, including different concentration. Three different types of liquid fertilizers – Magnicvet with NPK 7-1-5 + ME, Magnihortal with NPK 10-5-5 + ME and Humifulvil, with three different concentrations were used in the experiment. According to the methodology of work and the objective of the examination, following biometric parameters were analysed: height of plants (cm), stem thickness (mm), number of branches, number of flower buds and number of flowers. These biometric parameters were measured 40 days after planting into pots. The highest stem thickness has the plants fertilized with Magnihortal with concentration of 0,3 %. The highest number of flower buds and number of branches has the plants fertilized with Magnihortal with concentration of 0,4 %. The highest plant height has plants fertilized with Magnicvet with concentration of 0,3 %. The highest number of flowers has plants fertilized with Magnicvet with concentration of 0,4 %. On the basis of the results of all the examined biometrical parameters, it is determined that the nutrition with Magnihortal has shown the best results.
