Abstract

Praktični pokazatelji uzgoja maslina u Istri u zadnjih 20-tak godina pokazuju značajne gubitke
uroda uzrokovanih jačom sušom u fazi rasta i razvoja ploda. Uz primjenu navodnjavanja
postižu se pozitivni rezultati u očuvanju priroda, krupnoće ploda i randmana ulja što značajno
ovisi i o sorti.
Sami smo svjedoci sve učestalijih suša, pa je i otpornu i izdržljivu maslinu potrebno
navodnjavati da bi dala kvalitetan plod. Cilj rada je utvrditi da li navodnjavanje značajno
utječe na rodnost, postotak ulja u plodu i dinamiku rasta na području grada Poreča.
Istraživanje je provedeno na tri sorte 'Ascolana Tenera', 'Leccino' i 'Leccio del Corno' s dva
tretmana: navodnjavano i bez primjene navodnjavanja (kontrola) u tri repeticije. Uzorkovanje
se obavljalo osam puta tijekom rasta i razvoja ploda, odnosno od 14. srpnja do 7. listopada u
2016.-oj godini.
Rezultati dobiveni mjerenjima pokazuju da navodnjavanje nije ključno da bi rodnost,
randman i dinamika rasta ploda bila bolja. Kod sorte 'Leccino' su se pokazali zadovoljavajući
rezultati primjenom navodnjavanja. Zatim, sorta 'Leccio del Corno' je također dala dobre
rezultate, a 'Ascolana Tenera' je dala bolje rezultate pri nenavodnjavanim uvjetima uzgoja.
Iz dobivenih rezultata zaključujemo da je navodnjavanje potrebno samo kod nekih sorti, ali
treba uzeti u obzir količinu oborina, vrstu tla i mnoge druge čimbenike.

Abstract (english)

Practical indicators of olive growing in Istria in the last 20 years show significant losses of
yield caused by stronger drought in the growth and development of fruit. With the application
of irrigation, positive results of conservation of nature, fruit size and aroma of oil depend on
the variety.
We are witnessing more and more frequent droughts, so the resistant and durable olives need
to be irrigated to produce quality fruit. The aim of this thesis is to determine whether
irrigation has a significant impact on fertility, the percentage of fruit oil and the growth rate in
the Poreč area. Three varieties of 'Ascolana Tenera', 'Leccino' and 'Leccio del Corno' have
been investigated in two treatments: irrigated and without application of irrigation (control) in
three repetitions. Sampling was performed eight times during the growth and development of
fruit, from July 14 to October 7, 2016.
The results obtained by measurements show that irrigation is not essential in order to improve
fertility, oil percentage and dynamics of fruit growth. In the case of 'Leccino' variety,
satisfactory results have been demonstrated by irrigation. Then, the variety 'Leccio del Corno'
has also produced good results, and 'Ascolana Tenera' has yielded better results in the
unconventional conditions of breeding.
From the obtained results we conclude that irrigation is only necessary in some varieties, but
the amount of precipitation, soil type and many other factors should be considered.
