Abstract

The influence of organo-mineral fertilizer «Ekofus» on the growth, development and fluorescent parameters of ornamental plants Tagetes patula L. has been studied. It was found that the treatment of tagetes plants with ekofus accelerated the transition of plants to the flowering phase and increased the productivity of flowering, plant height, plant and root biomass. At the same time, no significant differences in the fluorescent parameters of plants in 3–4 weeks after treatment with ekofus were found in control and experimental plants, which indicates the absence of differences in the functional characteristics of the photosynthetic apparatus at late vegetation periods. Repeated spraying of tagetes plants during this period (in the phase of mass flowering) was also ineffective in terms of increasing photosynthetic activity.
