Abstract (croatian)

Istraživan je utjecaj različitih sustava obrade tla i korištenja slame kao malča te njihove interakcije na prinos i agronomska svojstva jare pšenice. Pokus je postavljen u sjeverozapadnoj Hrvatskoj na fluvioslu u humidnim uvjetima 2021. godine s tri sustava obrade tla (glavni faktor): konvencionalna obrada s oranjem do 20 cm u jesen i tanjuranjem u proljeće (CT), primjena kombiniranog oruđa do 15 cm u proljeće (MT), podrivanje na dubinu 35-40 cm u jesen te rahljenje kombiniranim oruđem do 15 cm u proljeće (RT). Svaki sustav obrade podijeljen je na parcele sa i bez slame kao podfaktorom pokusa. Obrada tla imala je značajan učinak (p<0,05) samo za hektolitarsku masu, dok je značajan učinak korištenja malča zabilježen za masu 1000 zrna i sedimentacijsku vrijednost. Interakcija obrade i slame pokazala je značajan učinak na sva istraživana svojstva (prinos, masa 1000 zrna, hektolitarska masa, sadržaj proteina, sadržaj vlažnog lijepka, sedimentacijska vrijednost). Prema dobivenim rezultatima može se zaključiti da se plitkom obradom (MT) ostvaruje zadovoljavajući prinos u odnosu na konvencionalnu obradu, ali je za optimizaciju kemijskih karakteristika prinosa jare pšenice potrebno testirati i druge agrotehničke mjere.

Abstract (english)

This paper presents the influence of different tillage systems and the use of straw as mulch and their interaction on yield and yield components (physical and chemical) of spring wheat. The experiment was established in northwestern Croatia on alluvial soils under humid conditions with three tillage systems (main factor): conventional tillage with plowing up to 20 cm in autumn and disc harrowing in spring (CT), use of multitiller up to 15 cm in spring (MT); subsoiling to a depth of 35-40 cm in autumn and loosening with multitiller up to 15 cm in spring (RT). Each tillage system has subplots with and without straw. The tillage factor had a significant effect (p < 0.05) only on hectolitre mass, while a significant effect of mulch use was observed on 1000-kernel weight and sedimentation value. The interaction of these factors had a significant effect on all the components studied (yield, 1000-kernel weight, hectolitre mass, protein content, wet gluten content, sedimentation value). From the short-term results obtained, it can be concluded that shallow tillage (MT) gives satisfactory yield compared to conventional tillage, but further optimization of the agrotechnical system is required to improve the chemical properties.
