Vermicompost is increasingly becoming popular as an organic fertiliser used for
different crops. Effects of vermicompost on strawberry plant growth and soil properties were
studied in this investigation. The research was performed in LatHort from 2015 to 2017.
Strawberry was grown on open field in rows. Two trials were established. In Trial 1, the
application of vermicompost with a dose of 50 mL per plant was compared to growing without
any fertilization. In Trial 2, several treatments were used: 1) only inorganic mineral fertilization
applied; 2) vermicompost applied with a dose of 100 mL per plant in planting holes, later mineral
fertilization applied; 3) vermicompost applied with a dose of 100 mL per plant in planting holes,
no additional fertilization applied; 4) vermicompost applied two times per season on the ground
around plants with dose of 50 mL per plant, no mineral fertilization applied. The plant growth
was assessed two times per season by evaluating the amount of leaves and plant height. Soil
dehydrogenase activity was evaluated during all growing seasons as indicator of soil microbial
activity. The application of vermicompost positively influenced plant growth in comparison to
growing without fertilization. In Trial 2, plant growth varied among years. During first two
growing seasons better plant growth was observed for plants fertilized by inorganic mineral
fertilizers, while later the growth levelled off for all treatments applied. The application of
vermicompost had positive influence on the soil dehydrogenase activity in contrary to fertilization
by mineral fertilizers.
