Abstract

Obična ili dvodomna kopriva (Urtica dioica) u modernom vremenu je zapostavljena biljna vrsta, no njezina hranjiva i ljekovita svojstva čine ju funkcionalnom hranom te je od velikog značaja u ekološkoj poljoprivredi i primjenjiva u mnogim industrijama. Biostimulatori su proizvodi prirodnog porijekla koji imaju efikasnu primjenu kod biljaka u uvjetima stresa ublažavajući nepovoljne biotske i abiotske čimbenike. U ovome radu istražene su potencijalne koristi od primjene biostimulatora u smislu utjecaja na morfološke pokazatelje i osnovni kemijski sastav koprive. Monofaktorijalni poljski pokus postavljen je na dvogodišnjem usjevu koprive po metodi slučajnog bloknog rasporeda u tri ponavljanja, a korišteni proizvodi su: Humistar, Phylgreen, Aminovital, Delphan Plus. Ustanovljeno je da biostimulatori nisu utjecali na morfološke pokazatelje niti ukupni prinos, no imali su različit učinak na razinu mineralnih tvari i specijaliziranih metabolita u biljci. Temeljem polučenog pozitivnog učinka, mogu se izdvojiti proizvodi Delphan Plus i Humistar.

Abstract (english)

Common or bivalve nettle (Urtica dioica) is a neglected plant species in modern times, but its nutritious and medicinal properties make it a functional food and it is of great importance in organic agriculture and is applicable in many industries. Biostimulants are products of natural origin that are effectively applied to plants under stress conditions by mitigating adverse biotic and abiotic factors. This paper explores the potential benefits of using biostimulants in terms of influencing morphological parameters and the basic chemical composition of nettle. The mono-factorial field experiment was set on a two-year crop of nettle according to the random block method in three replicates, and the products used were: Humistar, Phylgreen, Aminovital, Delphan Plus. It was found that biostimulants had no effect on morphological parameters or overall yield, but had different effects on the level of mineral substances and specialized metabolites in the plant. Delphan Plus and Humistar products can be distinguished based on their positive effect.
