Abstract

Tehnika plutajućeg hidropona svojim brojnim prednostima kao što je smanjenje upotrebe supstrata, hraniva i vode za navodnjavanje, omogućuje uzgoj plodovitog povrća. Rajčica za svježu potrošnju najviše se uzgaja tehnikom na supstratu, a metoda plutajućeg hidropona omogućila bi uzgoj isključujući nedostatke trenutno prisutne tehnike u uzgoju. Cilj rada bio je utvrditi mogućnosti uzgoja rajčice u plutajućem hidroponu temeljem utvrđenih gospodarskih i nutritivnih svojstava. Testirani su hibridni kultivar 'Florantino' i tri sorte 'Vita bella', 'Žuta kruška' i 'Choco cherry'. Među gospodarskim svojstvima određivan je broj plodova po biljci, masa ploda, prinos po biljci i udio netržnih plodova, a od nutritivnih svojstava udio suhe i topive suhe tvari te sadržaj vitamina C, β-karotena i likopena. Hibrid 'Florantino' pokazao se kao najuspješniji u uzgoju tehnikom plutajućeg hidropona na temelju praćenih svojstava.

Abstract (english)

The floating hydroponic technique, with its many advantages such as reducing the use of substrate, nutrients, and water for irrigation, enables the cultivation of fruitful vegetables. Tomatoes for fresh consumption are mostly grown using the drip irrigation technique, and the floating hydroponic method would enable cultivation excluding the shortcomings of the currently present cultivation technique. The aim of the work was to determine the possibilities of growing tomatoes in a floating hydroponic based on established properties. The hybrid cultivar 'Florantino' and three varieties 'Vita bella', 'Žuta kruška' and 'Choco cherry' were tested. The analysed properties where: number of fruits per plant; fruit weight; yield per plant; proportion of non-marketable fruits; proportion of dry and soluble dry matter; content of vitamin C, β-carotene and lycopene. The hybrid 'Florantino' proved to be the most successful in cultivation using the floating hydroponic technique based on the monitored properties.
