Резюме: Fertilizer from californian worms Lumbricol is known as one of the most effective organic fertilizes, soil fertilizer, which is used for organic farming and revitalization of exhausted soils. The nutrients therein are water soluble and easily absorbable in the plants form due to humic acids in it. In this study we explore the use of fertilizer in the production of seedlings of annual flowers. The aim is to obtain seedlings with better biometric behaviours for a shorter period of time. The study used the following species of plants: Antirrhinum, Tagetes, Zinnia and Verbena. Fertilizer was used as a component of the substrate in which the seeds were sown. Studied were the following variants: 10%; 20% and 30% of substrate for the sowing of seeds. As a control was used a standard substrate without the addition of fertilizer. The results obtained show that in all experimental variants seeds germinated faster than control, but the acceleration is negligible, within 1-2 days. More significant differences i occur subsequently - the plants in the treated variants form a more vigorous root system, a greater number of leaves with a greater leaf area and enter 6-7 days earlier phase in budding and flowering. The use of 20 percent bio-fertilizer was suggested.
