Abstract

Upravljanje sustavom tla u vinogradu ima višestruku i izuzetno važnu ulogu u uzgoju vinove loze (Vitis vinifera L.).U posljednje vrijeme povećan je interes za zatravljivanjem i malčiranjem vinograda u odnosu na upotrebu herbicida i stalnu obradu tla jer povoljno utječu na tlo i rast i razvoj vinove loze te kvalitetu grožđa.Tema ovog diplomskog rada je pokus koji je postavljen 2016. godine na sorti Chardonnay. Pokus se sastoji od četiri različita sustava upravljanja tlom. Jedan sustav predstavlja konvencionalnu obradu, drugi kontinuiranu izostavljenu obradu, treći je pod prirodnom vegetacijom koja se održava malčiranjem i četvrti sustav se održava podrivanjem i rotirajućom motikom. U trenutku berbe izdvojen je prosječan uzorak od 10 grozdova po varijanti na kojem je određen sadržaj šećera, ukupne kiseline, pH vrijednost te slobodni α-amino dušik (FAN). Isto tako utvrdio se prirod, broj grozdova po trsu te prosječna masa grozda. Dobiveni rezultati su pokazali da nema statistički značajne razlike među navedenim sustavima za održavanje tla, ali može se uočiti kako zatravljivanje i malčiranje pozitivno utječu na rast i razvoj vinove loze.

Abstract (english)

The management of the soil system in the vineyard has a multifaceted and extremely important role in the cultivation of vines (Vitis vinifera L.). Recently, there has been an increase in interest in cover crops and mulches of vineyards in relation to herbicide use and permanent soil cultivation, as they favorably affect the soil, growth and development of vines and grape quality. This thesis describes the experiment set up in 2016 on Chardonnay variety. The experiment consists four different soil management systems. One system represents conventional tillage , the other is a continuous no-tillage, the third is under natural vegetation, which is maintained by mulching, and the fourth system is underlined and rotating. At the time of harvest, an average sample of 10 clusters was varied according to the variations in sugar, total acidity, pH value and free α-amino nitrogen (FAN). They also followed the yield, the number of bunches per pound, the average mass of the grape.The results obtained showed that there are no statistically significant differences between the above mentioned soil maintenance systems, but it can be noticed that the cover crops and malting positively affect the growth and development of grapevine.
