Description
Summary:Since contemporary viticulture system sees an increasing use of foliar fertilizers, this paper aims to determine which of the liquid foliar fertilizers applied will create the best effect on agro-biological and technological properties, that is, on the quantity and quality of grape yield of the Cardinal variety. The research was done in 2013, on the trial plot of the Biotechnical Faculty, which lasted for one year. The trial was set using the randomized block design method. The training system is two-folded cordon formed at the height of 60 cm. Five types of foliar fertilizers were applied: Folifertil B11, Wuxal Super, Wuxal Magnesium, Wuxal Ferro and Slavol. The biggest effect on the yield of grapes of the Cardinal variety manifested in foliar fertilizers Wuxal Super, Folifertil B11 and Slavol. The highest yield per vine plant was achieved in the variant 2 (Wuxal Super), amounting to 4.5 kg, while the lowest yield (2.9 kg/vine plant) was recorded in the control. The highest sugar content in grape juice (18.65%) was measured in the variant treated with Folifertil B11 (variant 1).
