The impact of organic and mineral fertilization on sugar content in grapes
The sugar content in grapes is a specific characteristic for each variety, and it is influenced within certain variation limits by soil and climate factors and by technological factors. Grape vine nutrition represents an important factor for ensuring good quality of wine products. We conducted resea...

| 520 | 3 | |a The sugar content in grapes is a specific characteristic for each variety, and it is influenced within certain variation limits by soil and climate factors and by technological factors. Grape vine nutrition represents an important factor for ensuring good quality of wine products. We conducted research in order to comparatively assess the influence of two fertilization systems, organic and mineral, on the sugar content of grapes, varieties Burgund and Silvana. Organic fertilization was made with manure in doses of 30, 40 and 50 t/ha. For the mineral fertilization we used a complex fertilizer of the type NPK (S), zinc fertilizer [ 15/15/15(+3+Zn)], in doses NPK50 , NPK100 and NPK150 kg s.a./ha. Different plant nutrition ensured by the two fertilization systems led to different accumulation of sugars in each variety. Burgund variety accumulated sugars from 234.88 to 256.42 g/1, variation amplitude being between 14.33 - 21.54 g/1. For Silvana variety, the sugar content ranged between 158.07 and 196.68 g/1, with differences of 10.71 - 38.61 g/1. | |
