Cultivation of irrigated tomatoes with ozonised water under a Mediterranean climate in Algeria | Gojenje paradižnika zalivanega z ozonirano vodo v razmerah mediteranskega podnebja v Alžiriji

英语. This study presents the results of an experimental work carried out on tomato seedlings of the same varietal type, grown under a Mediterranean climate and irrigated with ozonised water at different ozonisation durations that vary from zero to 30 seconds. In order to assess the impact of aqueous ozone on the agronomic performances and the physicochemical characteristics of fruits. The tomatoes responded differently between themselves and the control batch. The results obtained showed precocity of germination, an increase in growth, development, and vigour in the experimental plants compared to the controls. The yield is proportional to the increase in the ozonisation time of irrigation water. During the reproductive phase of the plants, no negative effects were observed. The physicochemical characteristics of fruits could be evaluated; they are distinguished from higher sugar contents in the experimental tomatoes compared to controls, no great difference for the other criteria analysed, the latter were generally in accordance with the standardized values of the literature as well as with the applicable national regulations. Ozonisation of irrigation water is an effective and promising alternative method, which improves germination time and increases fruit yield without negatively affecting their marketability.

斯洛文尼亚语. Raziskava predstavlja rezultate poskusa izvedenega na sadikah paradižnika iste sorte, gojenega v mediteranskem podnebju in namakanega z ozonirano vodo, tretirano z ozononom od 0 do 30 sekund. Namen raziskave je bil ugotoviti učinek ozonizirane vode na agronomske in fizikalnokemijske lastnosti plodov. Odziv rastlin paradižnika se je razlikoval med posameznimi obravnavanji in glede na kontrolo. Rezultati so pokazali zgodnejšo kalitev, hitrejšo rast in hitrejši razvoj ter večjo vitalnost obravnavanih rastlin v primerjavi s kontrolo. Povečanje pridelka je bilo proporcionalno povečanju časa ozonizacije vode za zalivanje. V reproduktivni fazi rastlin ni bilo opaženih nobenih negativnih učinkov ozonizacije. Ocenjene fizikalno-kemijske lastnosti plodov so pokazale večjo vsebnost sladkorjev v obravnavanih rastlinah v primerjavi s kontrolo. V ostalih analiziranih parametrih ni bilo večjih razlik v primerjavi s kontrolo in so bile nasplošno v skladu s standardnimi vrednostmi iz literature kot tudi z veljavnimi nacionalnimi standardi. Ozoniranje vode za zalivanje je učinkovita in obetavna alternativna metoda, ki izboljšuje čas kalitve, povečuje pridelek plodov paradižnika brez negativnih učinkov na njihovo tržno vrednost.
