THE INFLUENCE OF VARIETY AND VINTAGE ON THE CHEMICAL COMPOSITION AND SENSORY PROPERTIES OF RED WINES IN PODGORICA SUBREGION (MONTENEGRO)

This paper presents the results of investigation of the influence of variety and vintage on the chemical composition and sensory properties of Vranac, Kratosija and Cabernet Sauvignon wines in Podgorica subregion (Montenegro) in vintages 2012 and 2013. The varietal wines were produced from the grapes grown at four different localities, according to a uniform manner (traditional method) in the winery of the Biotechnical Faculty, located at the experimental farm in Podgorica, at the vineyard location of Ljeskopolje. The analysis of basic chemical parameters of wines and sensorial testing of wines were carried out. The research findings show that variety and vintage (climatic conditions) significantly affected the chemical composition of wine. The higher content of alcohol and extract was measured in 2012 vintage, while the total acid content in wine was higher in2013, as a result of frequent rainfall during the growing season, especially in August and September. The highest content of alcohol, extracts and total acids was found in Kratosija wine, then in Cabernet Sauvignon, while the lowest content was found in Vranac wine in both vintages. According to sensory properties and average testing score for the two years of research, all wines fall into the category of superior wines

Uticaj folijarne prihrane na privredno tehnološke karakteristike sorte Kardinal

The study was preformed in the vintage 2015 with the aim to exame infuluence of use foliar fertilizers to the yield and the quality of Kardinal grapes. Folowing fertilazers were used: Folifertil B11, Wuxal Super, Wuxal magnezijum, Wuxal Ferro i Slavol. Each variant included 15 vines separated in three repetitions per 5 vines. The obtained results showed that fertilization had a positive effect on both: the yield and the content of sugar and acidity. The lowest average yield had the control variant. The differences are mostly and highly significant between variant with and without fertilizers. The highest yield was at Folifertil B 11 variant where the relative difference was from 0,45 to 1,6 in compare to not- fertilization. All variants of fertilization had higher content of sugar in compare to thecontrol variant.Tokom2015. godine ispitivan je uticaj specijalnih (kompleksnih) folijarnih đubriva na visinu prinosa i kvalitet grožđa sorte Kardinal. Korišćeni su sledeći preparati: Folifertil B11, Wuxal Super, Wuxal magnezijum, Wuxal Ferro i Slavol. U svakoj varijanti bilo je po 15 čokota rasporedjenih u tri ponavljanja po 5 čokota. Postignuti rezultati ukazuju da se đubrenje pozitivno odrazilo, kako na prinos tako i na sadrzaj šećera i kisjelina u grožđanom soku. Prosječno najmanji prinos grožđa imala je kontrola a razlike su uglavnom značajne i vrlo značajne u korist varijanata đubrenja. Najveći prinos bio je kod varijante Folifertil B11 a relativna razlika je od 0,45 do 1,6 u korist varijanata đubrenja. Sve varijante đubrenja su imale veći sadržaj šećera u širi od kontrole

Uticaj folijarne primjene makro i mikro elemenata na agrobiološke karakteristike sorte Muskat Italija na Ćemovskom Polju

The experiment was conducted at “13. JUL – Plantaže” in Ćemovsko polje, nearby Podgorica, during the one-year period (2015), on seven years old plantation on the variety of Muscat Italy, which is grafted on rootstock Paulsen 1103. The following liquid fertilizers were used: NPK 12-5-7 + ME + Bor 8%; NPK 12-5-7 + ME; NPK 9-0-6 + 10% CaO + 2% MgO i NPK 31-0-0 + ME; NPK 3-20-28 + 3% EDTA. Liquid fertilizer which showed the earliest start of tearing, activating buds, blossoming and veraison is NPK 12-5-7 + ME.Ogled je izveden u “13. JUL - Plantaže” a.d. na Ćemovskom polju u okolini Podgorice, u toku jedne godine (2015.), na zasadu starom sedam godina, na sorti Muskat Italija, koja je kalemljena na podlozi Paulsen 1103. Korišćeni su sljedeća tečna đubriva i to: NPK 12-5-7 + ME + Bor 8%; NPK 12-5-7 + ME; NPK 9-0-6 + 10% CaO + 2% MgO i NPK 31-0-0 + ME; NPK 3-20-28 + 3% EDTA. Tečno đubrivo koje je pokazalo najraniji početak suzenja, aktiviranja okaca, cvetanja i šarka je NPK 12-5-7 + ME
