The aim of this paper was to examine the influence of biostimulators, with or
without the use of fungicides, on seed quality parameters and early growth of
sunflower seedling. Testing was conducted at the Institute of Field and
Vegetable Crops in Novi Sad on cytoplasmic male sterile sunflower line
HA-26-PR. The experiment included six treatments: Slavol S (25%), Slavol S
(25%) + fungicide (a.m. metalaxyl-M), Bioplant Flora (2%), Bioplant Flora
(2%) + fungicide (a.m. metalaxyl-M), Slavol S (25%) + Bioplant Flora (2%),
Slavol S (25%) + Bioplant Flora (2%) + fungicide (a. m. metalaxyl-M) and
control. Results of the research showed that treating the seed with
biostimulators prior to sowing has a significant influence on seed
germination parameters and early growth of sunflower seedling. The individual
application of fertilizers, with or without the use of fungicide, gave a
positive effect, while their combination led to a negative effect. The
individual application of fertilizers, with or without combination with
fungicide, may increase germination energy by 5%, germinability by 6%, but
may also reduce the time of seed germination. Likewise, their use has a
positive effect on early growth of sunflower seedling.
