Chemical seed dressings as biologically active substances can adversely affect the survival of root-nodule bacteria inoculated onto legume seeds and thereby reduce the number of symbiotic nodules, and thus decrease the efficacy of the whole symbiotic process. In the pot experiments the effect of chemical seed dressing Vitavax 200 FS on nodulation and growth of two field pea cultivars: Cud Kalvedonu and Grapis was studied. Untreated and Vitavax 200 FS treated pea seeds were pelleted with inoculant containing symbiotic bacteria (Rhizobium leguminosarum bv. viciae) and sown into pots filled with perlite moistened with water solution of plant nutrients (without N). The inoculated with bacteria seeds were sown within 1–2 hours or 24 hours after storing at room temperature. After 4 weeks of growing plants in a growth chamber a number of root nodules was counted and fresh and dry mass of shoots were measured. The studied chemical seed dressing had no significant effect on nodulation and growth of both pea cultivars but only when seeds were sown directly after their inoculation with the symbiotic bacteria. Vitavax 200 FS affected negatively nodulation and plant growth when the treated seeds were sown 24 hours following the inoculation with symbiotic bacteria.
