Abstract

Za optimalan rast i razvoj vinova loza zahtijeva određene količine vode koje se uslijed
nedostatak oborina mogu nadoknaditi navodnjavanjem. Brojna istraživanja su potvrdila da je
lokalizirano navodnjavanje jedna od najboljih agrotehničkih mjera za povećanje dostupnosti
vode vinovoj lozi, te jedna od najučinkovitijih metoda navodnjavanja. Na lokaciji Petrovina
kojom gospodari Mladina d.d. Jastrebarsko provedeno je istraživanje kako bi se utvrdio
utjecaj četiri različita tretmana navodnjavanja na prinos vinove loze i kemijski sastav mošta.
Istraživanja su potvrdila da je varijanta navodnjavanja do poljskog kapaciteta tla za vodu uz
prihranu (fertirigaciju) ostvarila najviši prinos (13,6 kg/parceli), a varijanta bez
navodnjavanja uz prihranu najmanji prinos (6,4 kg/parceli). Najveća količina šećera ( Oe )
je zabilježena kod varijante s deficitarnim navodnjavanjem bez prihrane, a najmanja količina
šećera je zabilježena kod varijante navodnjavanje sa parcijalnim isušivanjem rizosfere (71
Oe ). Najveća količina ukupnih fenola je zabilježena kod varijante bez navodnjavanja uz
prihranu (123 mg/L), a najmanja kod navodnjavanja sa parcijalnim isušivanjem rizosfere bez
prihrane (61 mg/L). Najveća količina vinske kiseline je zabilježena kod varijante
navodnjavanje do poljskog kapaciteta tla za vodu (6,3 g/L), dok je najmanja količina vinske
kiseline zabilježena kod varijante bez navodnjavanja uz prihranu (4,3 g/L). Koncentracija
jabučne kiseline je bila najviša kod varijante navodnjavanja do poljskog kapaciteta tla za
vodu uz prihranu (3,2 g/L), a najmanja kod kontrolne varijante bez navodnjavanja i bez
prihrane ( ,1 g/L). Najveća koncentracija limunske kiseline je utvrđena kod varijante
deficitarno navodnjavanje bez prihrane (0,38 g/L), a najmanja kod varijante navodnjavanje
do poljskog kapaciteta tla za vodu bez prihrane (0,23 g/L). Navedeni rezultati ukazuju da
osim što je određenom tehnikom (sustavom) lokaliziranog navodnjavanja moguće
kvantitativno utjecati na visinu prinosa portugisca, također postoji mogućnost utjecaja i na
određene kvalitativne (kemijske) parametre mošta.

Abstract (english)

For optimal growth and development vines require certain amount of water which can, in
conditions of water deficit, be compensated with irrigation. Numerous studies showed that
localized irrigation is not only one of the best agricultural measurements for increasing
available water for vines, but also the moat efficient irrigation method. The experiment to
determinate the influence of different irrigation treatments on grape vines yield and chemical
composition of must was conducted on location Petrovina which is managed by Mladina d.d.
Jastrebarsko. Experiment confirmed that variant with irrigation up to water field capacity
with additional fertilization resulted in highest yield (13,6 kg/parcel), and variant without
irrigation but with additional fertilization resulted in lowest yield (6,4 kg/parcel). ighest
sugar content ( Oe ) as recorded in variant ith deficit irrigation ithout additional
fertilization and lo est sugar content as recorded in variant ith irrigation ith partial
rhizosphere dr ing (71 Oe ). The largest content of total phenols was observed in variant
without irrigation with additional fertilization (123 mg/L), and the lowest in irrigation with
partial drying rhizosphere without additional fertilization (61 mg/L). The largest content of
tartaric acid was observed in the treatment with irrigation to the polish soil capacity for water
(6.3 g/L), while the smallest content of tartaric acid was observed in the variant without
irrigation with additional fertilization (4.3 g/L). The concentration of malic acid was the
highest at an optimum irrigation to the polish soil capacity for water with additional
fertilization (3.2 g/L), and the lowest on the control variety without irrigation and without
additional fertilization (2.1 g/L). The highest concentration of citric acid was found in variant
deficit irrigation without additional fertilization (0.38 g/L), and the lowest in variant of
irrigation to the polish soil capacity for water without additional fertilization (0.23 g/L).
These results indicate that in addition to the specific technique (system) of irrigation possible
quantitative impact on yields Portugizac, there is also the possibility of an impact on certain
qualitative (chemical) parameters of must.
