Abstract

The stinging nettle (Urtica dioica L.) has recently been an unjustly neglected plant species, especially as a food. Because of its proven nutritional and medicinal properties, it is classified as a functional food. In the phase of intensive growth, there is a great need for nitrogen fertilizers, which can affect the quality of the final product, which is why the preparations approved in organic farming are also studied. Biostimulants are products of natural origin that can be effectively used on crops under stress conditions by mitigating adverse factors during cultivation. In this work, the potential benefits of applying biostimulants on the morphological parameters and the basic chemical composition of nettle were investigated. A monofactorial field experiment was set up with a two-year-old stinging nettle crop using the randomized block chain method in three replicates. The plantation was treated with four different biostimulants (Humistar, Phylgreen, Aminovital, Delphan Plus) and compared with the control variant. The biostimulants had no justifiable effect on the morphological parameters or the total yield, but they had different effects on the content of minerals and specialized metabolites in the plant, with the products based on amino acids (Delphan Plus) and humic acids (Humistar).

Abstract

Dvodomna kopriva (Urtica dioica L.) je u novije vrijeme nepravedno zapostavljena biljna vrsta, posebice kao prehrambena namirnica. Zbog dokazanih nutritivnih i ljekovitih svojstva, svrstava se u kategoriju funkcionalnih namirnica. U fazi intenzivnog porasta ima velike potrebe za dušičnim gnojivima što može umanjiti kvalitetu finalnog proizvoda, pa se istražuju preprati dozvoljeni i u ekološkom uzgoju. Biostimulatori su proizvodi prirodnog porijekla koji imaju efikasnu primjenu kod biljaka u stresnim uvjetima ublažavajući nepovoljne čimbenike tijekom uzgoja. U ovome radu istražene su potencijalne koristi od primjene biostimulatora na morfološke pokazatelje i osnovni kemijski sastav koprive. Monofaktorijalni poljski pokus postavljen je na dvogodišnjem usjevu koprive po metodi slučajnog bloknog rasporeda u tri repeticije. Nasad je tretiran s četiri različita biostimulatora (Humistar, Phylgreen, Aminovital, Delphan Plus) u usporedbi s kontrolnom varijantom. Biostimulatori nisu imali opravdani utjecaj na morfološke pokazatelje niti na ukupni prinos, no imali su različit utjecaj na razinu minerala i specijaliziranih metabolita u biljci, pri čemu se mogu se izdvojiti proizvodi na bazi aminokiselina (Delphan Plus) i huminskih kiselina (Humistar).
