Abstract
The paper presents the research of the influence of supplementary lighting sources on growth and yielding capacity of cucumber hybrids. The experiment was carried out in 2020-2021 in commercial greenhouses. Two sources of supplementary lighting were studied (option 1 – high-pressure sodium arc reflector lamps (SRL) “super” (Reflux), option 2 – LED-lamps (Phillips) on two cucumber hybrids: F1 Meva and F1 Svyatogor. The present research revealed statistically significant influence of factor B (source of supplementary lighting) on the overall crop productivity. To obtain the maximal yield (Meva F1 – 20,86 kg/m 2 , Svyatogor F1 – 18,21 kg/m 2 ), we recommend using LED-lamps as supplementary lighting sources.
