On the basis of the obtained results it was concluded that:
1. Nutrition with Lumbrical biofertilizer enhanced plant
growth. The increased growth rate of the vegetative
organs was accompanied by enhanced development
of the generative ones.
2. The positive effect of the biofertilizer on the
functional activity of the photosynthetic apparatus
was expressed through an increased content of the
photosynthetic pigments and improved leaf gas
exchange parameters.
3. The highest rates of pollen fertility were determined
in plants additionally treated with Lumbrical.
4. The yield was positively influenced by the
biofertilizer Lumbrical. A clear tendency for increase
in the average fruit mass and the pericarp thickness
was observed. The pigment content was higher in the
variants treated with biofertilizer
