Abstract
Vertikalni uzgoj je tehnika uzgoja bilja u više razina, jedna iznad druge. Često uključuje kontrolirane uvjete uzgoja, koji imaju za cilj optimizirati rast biljaka kao i primjenu hidroponskih tehnika uzgoja. Ovom tehnikom se najčešće uzgajaju mladi izdanci, odnosno biljčice u fazi razvijenih kotiledonskih listova u komorama za rast biljaka, uz primjenu dopunskog osvjetljenja. Pokus je proveden u tri ponavljanja u klima komori uz temperaturu od 25 °C i RVZ od 60 %. U ovom istraživanju korišteno je LED osvjetljenje s tri različita spektra (plavi – 450 nm, crveni – 620 nm i kombinacija plavog i crvenog spektra 50:50) s fotoperiodom u trajanju 14 sati. Laboratorijskom analizom utvrđen je prinos (kg/m2) i mineralni sastav nakon različitih tretmana LED osvjetljenjem. U uzgoju mladih izdanaka rotkvice uz primjenu različitog LED osvjetljenja nije zabilježena značajna promjena u prinosu, količini suhe tvari i količini dušika. Plavo osvjetljenje značajno je povećalo koncentracije kalija i magnezija, dok je crveno osvjetljenje pozitivno utjecalo na sve mikroelemente osim cinka i makroelemente osim fosfora. Kombinirano LED osvjetljenje povećalo je koncentraciju mikroelemenata i makroelemenata, osim dušika.
Abstract (english)
Vertical farming is a technique of growing plants on multiple levels, one above the other. It often involves controlled growing conditions to optimize plant growth and the application of hydroponic growing techniques. This method is used for growing microgreens, which are plants at the stage of developed cotyledon leaves, in plant growth chambers using supplemental lighting. The experiment was conducted in three repetitions in a climate chamber with a temperature of 25 °C and a relative humidity of 60%. In this research, LED lighting with three different spectra (blue – 450 nm, red – 620 nm, and a combination of blue and red spectra 50:50) was used with a photoperiod lasting 14 hours. Laboratory analysis determined the yield (kg/m²) and mineral composition after different LED lighting treatments. Radish microgreens were produced under various LED lighting conditions, showing no significant changes in yield, dry matter content, or nitrogen levels. Blue LED light significantly increased potassium and magnesium concentrations, while red LED light positively affected all micronutrients except zinc and all macronutrients except phosphorus. Combined LED lighting increased the concentration of both micronutrients and macronutrients, except for nitrogen.
