Abstract: The aim of the study is to investigate the effect of amino acid and seaweed-based fertilizers on the linear and physiological parameters of garden iris. The object of the study is the Lace Caper variety of garden iris. The experiment used Beres brand preparations (Beres AminoComplex and Beres Super Seaweed Extract). The field experiment was carried out on the experimental plot of the South Ural Botanical Garden-Institute in 2022–2023 (Bashkortostan, Ufa) in the following variants: control, fertigation, foliar treatment, a combination of fertigation and foliar spraying. The plants were treated three times per season at different stages of development: primary growth, budding, and early flowering. The experimental plants were treated with preparations in parallel at the same time in the morning. The plants were not watered during the testing period. The linear parameters of plant organs and water regime parameters were assessed. Agrostimulation with a preparation containing seaweed was more effective than with an amino acid preparation. Four linear indices (leaf length and width, flower diameter, and peduncle width) increased by 13–40 % in experiments with the seaweed extract. In experiments with the amino acid stimulator, two indices (foul length and flower height) increased by 7.0–12.6 %. The preparations had no effect on the water content and water-holding capacity of plants. However, in experiments with algae extract, water deficit significantly decreased with root and combined treatments – by 27.6 and 43.1 %, respectively. The preparation Beres Super Seaweed Extract can be recommended for growing irises.
