The field trial was carried out in the period 2015-2017 on alluvial-meadow soil type on the territory of the village of Voivodinovo – Central-South Bulgaria. The experiment was carried out with coriander of Yantar cultivar. The following
foliar fertilizers were included in the study at the respective rates: Variant 1 – Humustim – 1 l/ha, Variant 2 – Maxgrow
– 5 l/ha, Variant 3 – Tecamine vigor – 1.5 l/ha, Variant 4 – Yara Tera kristalon blue – 2.5 kg/ha, Variant 5 – Poly Plant
– 1 kg/ha. In order to follow out the effect of those products on the elements of productivity, seed yield and essential oil
content, the variants were compared to an untreated control (Variant 6). The results show: the structural elements of the
yield, i.e. the number of umbels per plant, the number of seeds per plant, the seed weight per plant and the 1000 seed
weight in the treated variants exceeded the untreated control by 4-15%, 5-15.2%, 3.2-15.4% and 6.5-12.5%, respectively.
The highest seed yield was produced under the treatment of coriander with leaf fertilizer Yara Tera kristalon blue in dose
of 2.5 kg/ha. An increase in the essential oil content from 2.8 to 9.4% was established after treatment with the foliar
applied products compared to the untreated control.
