Vpliv gnojenja z zeolitom in mineralnim dušikom na agronomske lastnosti pšenice (Triticum aestivum L.)

Kumin, Romana (author), Flajšman, Marko (mentor)

Pšenica (Triticum aestivum L.) je žito, ki spada v družino trav (Poaceae). Zeolit je sestavina sedimentnih kamnin vulkanskega izvora, ki je nastala z mešanjem vulkanske lave, pepela in morske vode. Največje nahajališče pri nas je Zaloška Gorica pri Žalcu. Zeolitna moka ugodno vpliva na rast rastlin in rodovitnosti tal, zadržuje vodo in pomaga rastlinam, da lažje preživijo sušo. Poljski poskus smo izvedli v rastni dobi 2021/2022 na laboratorijskem polju Biotehniške fakultete v Ljubljani, in sicer s pšenico sorte Amicus. Preučevali smo vpliv zeolita in mineralnega dušika na rast in razvoj pšenice. Spremljali smo 9 različnih obravnavanj v treh ponovitvah. Prvi faktor je bila količina zeolita (0 t/ha, 5 t/ha, 10 t/ha). Drugi faktor je bilo gnojenje z mineralnim dušikom v obliki KAN (0 kg dušika /ha, 160 kg dušika/ha [70-% odmerek] in 228 kg dušika/ha [100-% odmerek]). Med rastno dobo smo vzorčili tla za določanje talnega mineralnega dušika, spremljali potek rasti pšenice ter ob žetvi ugotovili pridelek zrnja in vsebnost beljakovin v zrnju. Pri naših obravnavanjih nismo mogli potrditi, da zeolit vpliva na rast in razvoj rastlin. Najpomembnejšo vlogo je imel mineralni dušik oz. dognojevanje z dušikom. Največji pridelek zrnja (8,5 t/ha) je bil dosežen na obravnavanju, pri katerem nismo dodali zeolita in smo uporabili100-% odmerek dušika. Največ beljakovin, 13,8 %, smo ugotovili v zrnju iz obravnavanja, kjer smo dodali 100-% odmerek mineralnega dušika.

• Title: Influence of zeolite and mineral nitrogen fertilization on agronomic performacne of wheat (Triticum aestivum L.)

Abstract

Wheat (Triticum aestivum L.) is a type of cereal belonging to the grass family (Poaceae). Zeolite is a component of sedimentary rock of volcanic origin, which is formed by the mixing of. The field trial was conducted on the premises of the Biotechnical Faculty in Ljubljana with wheat of the Amicus variety in the 2021/2022 growing season. We investigated the effects of zeolite and mineral nitrogen on the growth and development of wheat. We applied nine different treatments in three replicates. The first factor was the amount of zeolite (0 t/ha, 5 t/ha, 10 t/ha). The second factor was the amount of mineral nitrogen in the form of KAN (0 kg nitrogen/ha, 160 kg nitrogen/ha [70 % dose] and 228 kg nitrogen/ha [100 % dose]. During the growing period, we took soil samples, monitored growth and determined seed yield and proetin content at harvest. We cannot confirm that zeolite has an effect on plant growth and development. Fertilization with nitrogen had the greatest influence. The highest grain yield (8.5 t/ha) was achieved with a treatment in which no zeolite and a 100 % nitrogen dose was added. The highest values of protein content in the grain were achieved in the treatment with 100 % of mineral nitrogen (KAN).
