Seaweed extracts have many uses. Growth stimulation results obtained from different plant species are mentioned. Also, algae extracts are used to reduce biotic and abiotic stress. Salt stress is one of the most important factors decreasing the productivity of plants. High soil salinity can have a negative effect on major physiological processes. In our work, we investigated the response of Phaseolus vulgaris L. cv. ?Berggold? plants treated with SuperFifty solution (1:1000 and 5:1000), under salt stress conditions (100 mM NaCl). SuperFifty® 0-0-8 is an organic fertilizer from brown marine alga - Ascophyllum nodosum (L.) Le Jolis. It is a highly concentrated product: 500 g dry mass per liter. After seeds germination, the plants were grown in the plant growth chamber. Been plants have been influenced by salt stress at the end of vegetative growth period. The plants were sprayed with SuperFifty solution. Three replicate pots per each variant were used. Sodium chloride, in tested dose, caused inhibition of the following physiological parameters: plant height, foliar area, relative water content. The seaweed extract contained in the Super Fifty product can help reduce the physiological stress caused by salt. The lowest tested concentration of SuperFifty (1:1000) has shown its effectiveness in reducing saline stress.
