The study aimed at determining the impact of organic fertilization, humic acids and
irrigation on potato yielding in organic production system. Fertilization variants included: Humac
Agro; manure; vermicompost; Fertil Bioilsa C-N 40-12.5; manure + Humac Agro; vermicompost
+ Humac Agro; Fertil Bioilsa C-N 40-12.5 + Humac Agro. Irrigation was carried out using drip
lines. The highest tuber yield was determined on treatments fertilized with vermicompost. The
combined application of organic fertilizers and humic acids resulted in increased total yield
between 6 and 9%, whereas commercial yield from 5 to 10%. Application of fertilization resulted
in increased total yield of tubers in individual fertilizer variants from 1.9 to 10.8 t ha-1
, and
commercial yield from 1.6 to 12.3 t ha-1
. Water-use efficiency remained in the range from 35.2
to 113.1 kg mm-1
, whereas irrigation water-use efficiency from 9.9 to 166.3 kg mm-1
. Humic
acids used in the study enhanced fertilizer and water-use efficiency.
