<abstract xmlns="http://www.w3.org/1999/xhtml"> In the years 2010 and 2011, a field trial was established in the administrative area Kolinany, Barack farm. We evaluated the growth of aboveground phytomass depending on different levels of fertilization. In the climatically unbalanced growing years, the phytomass yield of amaranth was different. Extremely wet conditions during the growing season exceeding long-term normal precipitation confirmed the assumption of high growth of aboveground phytomass in the observed amaranth genotype. In 2010, the highest amaranth aboveground dry matter in phytomass reached 3231.40 g m2 in the variant with the fertilization dose of 150 kg ha-1. In the climatically different year 2011 with lower precipitation, the highest aboveground phytomass yield of 3956.95 g m2 was reached in the fertilized variant as well.</abstract>
