Impact on Economic Foliar Technological Features a Variety Cardinal

Abstract

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.
