Influence of Type of Management and Climatic Conditions on Productive Behavior, Oenological Potential, and Soil Characteristics of a ‘Cabernet Sauvignon’ Vineyard

Abstract

(1) Background: Degradation of soils and erosion have been described for most of the soils presented along the Maule Valley. Organic and integrated management promotes agroecosystem health, improving soil biological activity. Due to this, the aim of this research was to study the effect of organic, integrated, and conventional management on the productive, oenological and soil variables of a vineyard cultivated under semiarid conditions during 5 consecutive seasons; (2) Methods: Yield, grape and wine oenological, and soil physicochemical parameters were evaluated. Bioclimatic indices were calculated in the studied seasons; (3) Results: Conventional management allowed to improve yield and the number of bunches per vine compared to organic management. However, this latter enhanced mineral nitrogen and potassium content in soil. Based on bioclimatic indices, heat accumulation improved number of bunches per plant and most of the soil physicochemical parameters; (4) Conclusions: Organic management improved the accumulation of some microelements in soils at the expense of yield. Organic matter decreased along the study was carried out. Season was the conditioning factor of the variability of most of the studied parameters, while the interaction between season and type of management affected soluble solids, probable alcohol and pH in grapes, and total polyphenol index and pH in wines.

Exploration and Comparison of the Behavior of Some Indigenous and International Varieties (Vitis vinifera L.) Grown in Climatic Conditions of Herzegovina: The Influence of Variety and Vintage on Physico-Chemical Characteristics of Grapes

“…The high quality of Cabernet Sauvignon grapes was also shown by the results of the must physicochemical analysis, which is also confirmed by the research of other authors [ 65 , 66 , 67 , 68 ]. The results of studies on grape quality of this variety in neighboring regions (Croatia, Serbia) [ 31 , 69 , 70 ] show that the total soluble solids (TSS) content was at the level of the lowest measured value of TSS in our research (Trebinje, 2021—22.8 °Brix), while the TA content was slightly higher (6.80 g·L −1 –9.20 g·L −1 ).…”

Seaweeds in viticulture: a review focused on grape quality

“…A soluble extract of A. nodosum applied foliarly to grapevines at a concentration of 0.5 % (v/v) increased leaf dry weight, berry weight and volume, and Ca, Zn, S, B and chlorophyll leaf contents in 'Narince' grapevine variety (Sabir et al, 2014). Fruit set and productivity in 'Carmenère' grapevines cultivated under cold and warm climates was improved after the foliar application of a commercial A. nodosum extract (BM86®) at a dose of 3 L/ha (Gutiérrez-Gamboa et al, 2019b). Foliar application of a commercial fertilizer (Primo®) elaborated based on an A. nodosum algae sprayed in multiple applications of 0.1 mL/L increased leaf size and chlorophyll content, fruit set, number of clusters per shoot, rachis length, berry weight and size, soluble solids and pH values in musts, and reduced berry dehydration in 'Perlette' table grapevine variety (Khan et al, 2012).…”

“…Due to the aforementioned problems and the current global situation in relation to the demand for organic fertilizers in developed countries, an opportunity for the use of algae in viticulture has been opened, as they have been widely used in other horticultural crops with the aim to improve quality and disease resistance (Battacharyya et al, 2015). Based on this, the utilization of algae in viticulture is currently under study and there are few reports in the literature assessing its effect on avoiding grapevine diseases and improving grape and wine quality (Aziz et al, 2003;Sharma et al, 2014;Zhang et al, 2016;Frioni et al, 2018Frioni et al, , 2019Mondello et al, 2018;Gutiérrez-Gamboa et al, 2019b;Salvi et al, 2019;Taskos et al, 2019;Gutiérrez-Gamboa, 2020;Gutiérrez-Gamboa et al, 2020a,b,c;Thankaraj et al, 2020).…”

Biostimulants in Viticulture: A Sustainable Approach against Biotic and Abiotic Stresses

“…Intensive food production for animal and human consumption, for which conventional agricultural systems have been adopted, has led to the haphazard and promiscuous use of agrochemical products, generating several negative and dangerous effects for the agroecosystem, including the conservation of the biodiversity connected to these agricultural systems [1][2][3][4][5]. Farmers commonly use fertilizers to sustain crop yield and profitability [6].…”
