Abstract

U diplomskom radu se obrađuje tema vezana za navodnjavanje šećerne repe, pomoću sustava kap po kap uz dodatak mineralnih hranjiva otopljenih u vodi. Klimatske promjene mogu se manifestirati kao promjena prosječnih klimatskih elemenata (temperatura zraka, oborina, relativna vlaga zraka, brzina vjetra, insolacija) ili kao promjena raspodjele klimatskih događanja u odnosu na prosječne vrijednosti. Posljedice klimatskih promjena su pojava suša, koje mogu biti različitog intenziteta i dužine trajanja. Na području Hrvatske sušna razdoblja javljaju se u prosjeku svake treće do pete godine te prouzrokuju smanjenje prinosa i njihovu kakvoću. Primjenom odgovarajućeg sustava navodnjavanja moguće je ostvariti planirane prinose uzgajanih kultura. Istraživanje prinosa i sadržaj šećera kod šećerne repe provedeno je u Baranji na Belju d.d u 2015. godini. Godina 2015. je bila vrlo sušna zbog čega se na osnovu izmjerenih količina oborina i vode u tlu navodnjavanje primjenjivalo 15 puta. Tlo je ritska crnica (humoglej). Tijekom istraživanja utjecaja primjene navodnjavanja sustavom kap po kap (i u vodi otopljenih hranjiva) statistički je značajno povećan prinos i sadržaj šećera u korijenu repe.

Abstract (english)

The thesis deals with topics related to the irrigation of sugar beet, using the system drop by drop with the addition of mineral nutrients dissolved in the water. Climate change can be manifested as a change of average climatic elements (air temperature, rainfall, relative air humidity, wind speed, insolation) or as a change in the distribution of climatic events in relation to average values. Climate changes are the occurrence of droughts, which can be of different intensity and duration. In the Croatian territory, dry periods occur on average every three to five years and cause a decrease in yield and their quality. By applying a proper irrigation system it is possible to achieve the planned crop yields. Research on yield and sugar content in sugar beets was conducted in Baranja Belje d.d in 2015. The year 2015 was very dry due to which, on the basis of the measured precipitation and water levels, irrigation was applied 15 times. The ground is a ruth crunch (humogley). During research on the effect of application of irrigation drip system (and in the water of dissolved nutrients) is statistically significantly increased yield and sugar beet root.
