Ocimum basilicum L. je najraširenija vrsta roda Ocimum, a unutar vrste postoji šest glavnih botaničkih varijeteta i kultivara: var. basilicum ‘Genovese’, var. difforme, var. minimum, var. purpurascens, ‘Dark Opal’ i var. thyrsiflorum. Primjena mikroelemenata, kao dodataka makroelementima, značajno djeluje na prinos biljne mase i sastav eteričnog ulja kod mnogih ljekovitih i aromatičnih biljnih vrsta. Cilj ovog istraživanja bio je utvrditi utjecaj različitih tretmana folijarne gnojidbe na prinos pet kultivara O. basilicum (var. basilicum ‘Genovese’, var. difforme, var. minimum ‘Bush Basil’, var. purpurascens i ‘Dark Opal’). Pokus je proveden po split-plot dizajnu u tri ponavljanja s četiri folijarna gnojidbena tretmana: kontrola, Drin (2 x 1 ml/l), bor (2 x 1,75 g/l) i cink (2 x 1,25 g/l). Tretmani su primijenjeni 15 i 5 dana prije pune cvatnje. Utvrđene su statistički značajne razlike između kultivara u visini biljaka, broju grana i prinosu (svježe i suhe tvari). Međutim, nije utvrđena statistički značajna razlika između gnojidbenih tretmana. U tijeku je komparativna analiza utjecaja različitih gnojidbenih tretmana na prinos i sastav eteričnog ulja sorata bosiljka., Ocimum basilicum L. is the most commercial species in the genus Ocimum and within the species there are six main botanical varieties and cultivars: var. basilicum ‘Genovese’, var. difforme, var. minimum, var. purpurascens, ‘Dark Opal’ and var. thyrsiflorum. Application of micronutrients, as supplements to macroelements, has been reported to have significant effects on herb yield and oil contents on a wide range of medicinal and aromatic plants. The aim of the current study was to determine the influence of different foliar fertilization treatments on yield of five O. basilicum cultivars (var. basilicum ‘Genovese’, var. difforme, var. minimum ‘Bush Basil’, var. purpurascens and ‘Dark Opal’). The field trial was carried out using a split-plot design with three replications. Four treatments included: control, Drin (2 x 1 ml/l), Boron (2 x 1.75 g/l) and Zinc (2 x 1.25 g/l). The treatments were applied at both 15 and 5 days before full bloom. As expected, cultivars showed significant differences in plant height, number of branches and yield (fresh and dry matter). However, no significant differences were observed among fertilization treatments in any of analyzed traits. Comparative analyses concerning influences of different treatments on essential oil yield and composition of basil cultivars are in progress.
