Abstract
Cilj ovog istraživanja je bilo ustanoviti na koji način folijarna primjena različitih oblika dušičnog gnojiva može utjecati na kemijski sastav grožđa Graševina. Pokus je postavljen 2013. godine na sorti Graševina, na pokušalištu Jazbina. Korištena su četiri gnojidbena tretmana, od kojih su tri folijarno primjenjeni, Drin, urea i amonij nitrat, dok je NPK tretman primijenjen kao redovita gnojidba u tlo. Udio dušika mijenjao se u fazi pred cvatnju i fazi bobice veličine graška gdje je tretman ureom imao najviše vrijednosti i značajno se razlikovao od ostalih tretmana. Folijarna gnojidba nije utjecala na sadržaj šećera i ukupnih kiselina. Folijarna gnojidba također nije utjecala na prinos i masu grozda, kao ni na sadržaj ukupnog amino dušika.
Abstract (english)
The main objective of this research was to determine in which way foliar application of nitrogen can affect the chemical composition of Italian Riesling grapes. The experiment was set up in 2013 on the Italian Riesling cultivar, at Jazbina experimental station. Four different fertilizing treatments were used, three of which were applied foliarilly (Drin, urea and ammonium nitrate), while NPK treatment was applied as a regular fertilizer to the soil. The content of nitrogen in leaves was changed before the bloom phase and in the pea-size phase, where the urea treatment affected the highest values and significantly diversed from other treatments. Foliar fertilization did not affect the amount of sugar or total acidity in grapes, neither did it affect the yield and weight of the grapes. It also did not affect the amount of total amino nitrogen in grapes.
