This pilot study examined whether treatment with Vortex Process Technology (VPT) of the irrigation
water used on tomato (Solanum lycopersicum) plants had any effect on plant growth. In a block
experiment, with two blocks comprising 12 vases containing 1 L water and two tomato plantlets,
treatment in which, nutrient solution was based on Vortex-treated water was compared with an control
using untreated water. All vases were kept in a static aerated culture system in a daylight chamber for
four weeks. The results showed that the effect of the two blocks exceeded the effect of vortex
treatment in terms of leaf area and weight of fresh and dry matter. Plant height, stem width and
internodal length were significantly different in tomato plants grown in Vortex-processed water
compared with the untreated control. Number of leaves did not vary between the treatments. The study
focused only on the early plant growth phase and no other influencing factors were studied.


I föreliggande pilotstudie undersöktes inverkan av näringslösning som bereddes på vatten
behandlad med Vortex Process Technology, VPT, på tomat (Solanum lycopersicum)
småplantor. Studien genomfördes som ett blockförsök, med två block och tolv enlitersvaser
per block. I varje vas fanns två plantor. Plantor i kontrolledet odlades i näringslösning beredd
på obehandlat vatten. Försöken genomfördes I en dagsljuskammare under fyra veckor i ett
hydroponiskt system. Resultaten visade att effekten av blocken var större än effekten av
behandlingen med hänsyn till bladstorleken samt färsk- och torrvikt. Planthöjden,
stamdiametern samt internodländgen påverkades signifikant. Antal blad varierade inte mellan
behandlingarna. Föreliggande studie fokuserade enbart på småplantstadium. Inga andra
påverkande faktorer undersöktes.
