THE EFFECT OF FERTILISERS ON THE QUALITY OF PETUNIA X HYBRIDA „DUVET PINK“

Abstract

The research was conducted in order to analyse the effect of different types of fertilizers on morphological parameters of Petunia x hybrida „Duvet pink“. Three different types of liquid fertilisers – 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: plant height (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 and number of branches has the plants fertilized with Magnicvet with concentration of 0,4 %. The highest number of inflorescences has the plants fertilized with Magnicvet with concentration of 0,3 %. The highest plant height has plants fertilized with Magnihortal with concentration of 0,4 %. The highest number of flowers has plants fertilized with Humifulvil with concentration of 0,5 %. The analysed biometric parameters have shown that the liquid mineral fertiliser Magnicvet is more appropriate compared with the liquid mineral fertilizers Magnihortal and Humifulvil.
