Abstract
This paper presents results of study of the influence of 4 different organic fertilizers
(Chap liquid, Biofert, Guano and Stallatico jolly) on some of the most important
productive traits of lavender seedlings. All fertilizers were applied once, except Chap
Liquid which was applied twice. Two control variants were included in the
experiment: one that was not fertilized and the other one where the organic-mineral
fertilizer Sapro elixir was applied. The studies of influence of organic fertilizers at
the height of the stems, weight of the above ground part and the mass of roots of the
lavender seedlings was done in greenhouse. The highest average height of lavender
seedlings was measured on a control variant fertilized with organo-mineral fertilizer
Sapro elixir (25.5 cm) as well as variants where Chap fluid was applied twice - 24.8
cm and variant Biofert - 24.6 cm. Plants with the lowest stem height were measured
on non fertilized control - 19.6 cm. All variants where organic fertilizer was applied
had statistically significantly higher stem compared to plants grown in non fertilized
control. In the Biofert variant was measured the largest average weight of the above
ground part of the plant - 22.9 g, while the lowest was in non-fertilized control - 12.1
g. The average weight of the above ground part of the plant treated with organic
fertilizers was significantly higher than in non fertilized control. The weight of the
above ground part of the plant of lavender seedlings fertilized with Biofert was
statistically higher than all other fertilized variants, but also higher than control
variants fertilized with organo-mineral fertilizer
