Abstract

U kontekstu rastućih klimatskih promjena, ovaj diplomski rad fokusira se na izazove i potrebe
za navodnjavanjem u vinogradarstvu, s posebnim naglaskom na vinogradarskoj regiji Istre u
Hrvatskoj. Metodologija je obuhvatila određivanje potreba za navodnjavanjem vinograda,
evaluaciju učinkovitosti iskorištenja vode (WUE) i analizu razlika u WUE kod različitih varijanti
navodnjavanja. Klimatski parametri, uključujući referentnu evapotranspiraciju (ET) i ukupne
efektivne oborine, analizirani su na području klimatološke postaje Pazin, pokazujući značajnu
varijabilnost. Indeks suše (AI) dodatno ukazuje na klimatske izazove. Statistička analiza je
potvrdila značajne razlike u prinosima između kontrolne grupe i varijanti navodnjavanja.
Najučinkovitija strategija navodnjavanja bila je 25% ET. Zaključak rada ističe potrebu za
daljnjim istraživanjima za optimizaciju količina vode i agrotehničkih mjera, s ciljem povećanja
održivosti i prinosa u vinogradarstvu.

Abstract (english)

In the context of rising climate change, this thesis focuses on the challenges and needs for
irrigation in viticulture, with a special emphasis on the wine-growing region of Istria in Croatia.
The methodology encompassed determining the needs for vineyard irrigation, evaluating
water use efficiency (WUE), and analyzing differences in WUE across various irrigation
variants. Climatic parameters, including reference evapotranspiration (ET) and total effective
precipitation, were analyzed in the area of the Pazin climatological station, showing significant
variability. The drought index (AI) further indicates climatic challenges. Statistical analysis
confirmed significant differences in yields between the control group and irrigation variants.
The most effective irrigation strategy was 25% ET. The conclusion of the study highlights the
need for further research to optimize water quantities and agronomic measures, aiming to
increase sustainability and yields in viticulture.
