Sažetak
Ispitivan je uticaj biostimulatora EPIN-extra i cirkon na prinos nadzemne biomase sorte bosiljka 'sitnolisni'. Istraživanja su provedena na tri tipa zemljišta: ritska crnica, černozem i gajnjača. Ogled je zasnovan direktnom setvom semena, po modelu potpuno slučajnog blok sistema u četri ponavljanja. Prva primena EPINextra bila je u dozi 50 ml/ha, u vreme porasta biljaka bosiljka (visina oko 20 cm). Druga primena bila je u dozi 40 ml/ha, u fazi pred cvetanje biljaka. Prva primena cirkona bila je u dozi 30 ml/ha, u vreme porasta biljaka (visina oko 20 cm). Druga primena bila je u dozi 40 ml/ha, u fazi pred cvetanje biljaka bosiljka. Treća varijanta, bila je bez primene biostimulatora, odnosno kontrolna varijanta. Najveći prinos nadzemne biomase bosiljka ostvaren je na zemljištu u tipu černozema, a najmanji na zemljištu u tipu ritske crnice. U varijanti sa biostimulatorom cirkon, ostvaren je veoma značajno veći prinos nadzemne biomase bosiljka od varijante sa biostimulatorom EPIN-extra i kontrolne varijante.
Abstract
The influence of Epin-extra and cirkon biostimulators in the above-ground biomass yield varieties of basil 'sitnolisni'. Research was conducted on three soil types humogley, chernozem and brown forest. The experiment was based direct sowing of seeds on the model completely randomized block design with four replications. Epin- extra first application was the extra dose of 50 ml/ha at the time of basil plant growth (height 20 cm). Another application is in the dose was 40 ml/ha at the stage before flowering plants. The first application of cirkon in the dose was 30 ml/ha at the time of plant growth (height 20 cm). Another application is in the dose was 40 ml/ha at flowering stage of the plant basil. The third option was no application biostimulators and control variant. The highest yield of above-ground biomass basil was achieved on the chernozem soil, and the lowest on the type of soil in the marsh soil. In the variant with cirkon biostimulator achieved very significantly higher above-ground biomass yield of basil varieties with biostimulator epi-extra and control variant.
