The work examined the influence of two organic fertilizers on growth and flowering of plumed cockscomb(Celosia plumosa (Voss) Burv.). Two commercially available organic fertilizers, ‘Slavol’ and ‘Ecobooster 2’ were used. Plants of plumed cockscomb were produced in polystyrene containers. The investigation was conducted in a field experiment laid out in a randomized complete block design with three replicate plants per treatment. During production fertilizers were applied in the prescribed dosage every seven days. The results showed that ‘Slavol’ had positive influence on plant high, leaf width and length and on flower characteristics.
