Alfalfa (Medicago sativa), variety Zuzana, was sown into pots in spring and summer. Alginate preparations S-90 and Micromist were applied on seed (10 ml.kg-1) or on the leaf at the stage of 4-6 true leaves (22 ml.l/l). Length and thickness of stems, number of leaves, branches and stems per 1 plant and weight of 1 stem were measured. Soil compaction significantly decreased length of stems (on average by 8-31 %), thickness of stems (by 3.5-13.5 %), leafiness (by 5-17 %), branching (by 41.2 %) and weight of stems (by 14.6 %), particularly in earliest phases of the plant development.
