The researches were carried out in the Valea Calugareasca viticultural center in a vineyard with the Cabernet Sauvignon variety. The experimental device included as an experimental factor the soil maintenance system (black field, permanent grass with herbs from spontaneous flora, lawn, phacelia, white clover and vetch). The viticultural climate, characterized by a high heliothermic regime, against the background of reduced water resources and the technological variants experienced had a differentiated impact on the quantity and quality of grape production. The soil maintenance variants with Phacelia and vetch ensured significant differences in production, +1.052 kg/vine and +0.924 kg/vine, respectively. The deviation from the optimal content of the sugar of 12.0-12.8% was registered in the case of the soil maintenance variant with Phacelia, vetch and white clover. The leaf area required to produce one gram of grape in the conditions of maximum sugar accumulations was between 11.05 cm2/g grape (the soil maintenance system variant by phacelia) and 9.92 cm2/g grape (the soil maintenance system variant as black field).
