“…The acid content in the must is an important indicator of the quality of grapes, because the taste and harmony of grapes and produced wine depends on their presence (Popović, 2020). The results of two -year study demonstrated that the average acid content in must was satisfactory and characteristic for Žižak variety grown in agroecological conditions of Podgorica vineyard area.…”

Results of a two-year study of the influence of different vine loads with fertile buds on elements of grape yield and quality of Žižak grape variety are presented in this paper. The research was conducted in the Podgorica sub region, at the Lješkopolje site. Four different vine loads with fertile buds were applied: 14 buds, 18 buds, 20 and 24 buds per vine. The results of this research show that the applied loads significantly influence the examined parameters of the autochthonous variety Žižak. The highest percentage of developed and fertile shoots, as well as the average number of flowers per bud, had a variant with load of 14 buds. The relative coefficient of yielding in all examined load variants had mean values. In terms of the number of flowers per fertile shoot in the two-year average, variants with a load of 18 and 14 buds (1.44 and 1.39) stood out. The highest yield of grapes in the two-year average had the variant with a load of 24 buds-3.60 kg/vine, while the highest bunch weight had the variant V1-185 g. The quality of grapes also varied significantly under the influence of the vine load with fertile buds. The highest sugar content in must had variant with a load of 18 buds (22.32%), while the highest acid content (6.27g/l) was recorded in the variant with 24 buds per vine.

“…However, several studies confirmed that the combined application of mineral and organic fertilizers give the best results in terms of grape yield (4.7 kg vine⁻ 1 ) and the physical and chemical characteristics of bunches and berries (14.72% sugar) [70,71]. Only individual application of organic fertilizers led to the lower yield (3.6 kg vine⁻ 1 ) [70,72] and lower content of sugar in berries (14.29%) [70,73], as well as to the increase in berry acidity (4.32 g L⁻ 1 ) [70]. The overall polyphenol concentration is higher in organic grapes, resulting in a higher protection from oxidation [72].…”

The State of Soil Organic Carbon in Vineyards as Affected by Soil Types and Fertilization Strategies (Tri Morave Region, Serbia)

Due to specific soil properties and management practices, soils in vineyards are sensitive to degradation. The aims of this study were to examine (i) the state of soil organic carbon (SOC) in vineyards compared to other agricultural land, (ii) the influence of different fertilization strategies and soil type on SOC content and (iii) the rate of SOC change over time and potential of deep tillage for SOC preservation in subsoil. The study was carried out at 16 representative vineyard locations of the Tri Morave region, which represents the largest vine growing region in Serbia. The analyzed area included 56 vineyard plots. Results showed that SOC stocks in the topsoil and subsoil were lower than the average for agricultural land in Serbia. The soil type was an important predictor of carbon storage in the topsoil. An adequate application of inorganic fertilizers or green manure combined with farmyard manure initially resulted in the highest SOC contents. Continuous application of inorganic fertilizer without organic amendments has led to a decrease of SOC in topsoil. High rates of SOC stock change in topsoil accompanied a rapid reduction of SOC in the earlier stage of cultivation. In all investigated subsoils, SOC increased, except for unfertilized vineyards. Deep tillage has the potential to preserve SOC in the deeper soil layer and prevent carbon loss from the topsoil. More attention should be paid to the soil conservation practices to meet environmental sustainability of viticulture.

“…The lack of potassium is manifested by lower yields and quality of the tubers produced. Poor potassium nutrition also causes a decrease in specific gravity [20,21].…”

“…The positive effect of manure is also reflected in the increase of the humus component of the soil and the faster warming of the soil in early spring, when higher temperatures are needed for the growth and development of the tuber sprouts. Through its mineralization, plant nutrients and carbon dioxide are released, essential substances in the process of photosynthesis [21,22]. In addition, the released CO 2 contributes to the activation of nutrients from the existing land reservoir, increasing their accessibility to plants [23].…”

This study was conducted to evaluate the effect of liming (CaCO3 1000 kg ha−1) and application of organic fertilizers (rotted farmyard manure 40 t ha−1) and six different combination of mineral fertilizers: NPK 15:15:15 800 kg ha−1 + KAN (calcium ammonium nitrate) 240 kg ha−1; NPK 15:15:15 400 kg ha−1 + MCB (water-soluble mineral fertilizer NPK 13:11:20 + 2MgO + microelements + humic acid) 300 kg ha−1 + KAN 125 kg ha−1; MCB 400 kg ha−1; MCB 400 kg ha−1 + KMg (water-soluble mineral fertilizer Multi KMg 13:0:43 + 2MgO) 100 kg ha−1; MCB 600 kg ha−1 + KMg 100 kg ha−1 and MCB 800 kg ha−1 + KMg 100 kg ha−1 on yield and other productivity parameters of potato (Kennebec variety). The aim of the research was to optimize the system of potato plant nutrition for maximum profitability in the future potato production on acid soils of mountainous region of Montenegro. The experiments were carried out during 2015 and 2016, on Dystric Cambisols. The results obtained suggested that in both years, the highest values for all studied parameters were measured on plots with combined application of liming, organic and mineral fertilizers. In addition, a significant influence on the increase in the number of tubers per plant, the average tuber weight and the total yield was also demonstrated in all individual trials of potato nutrition, and the interaction of organic manure and mineral fertilizer. Fertilizing with rotted farmyard manure had significantly increased potato productivity, with the effect more pronounced in treatments with liming. The highest number of tubers (6.2 and 7.2), average tuber weight (93.5 g and 101.0 g) and yield (27.6 t ha−1 in 2015 and 34.8 t ha−1 in 2016, respectively) were obtained using combinations of MCB 800 kg ha−1 + KMg 100 kg ha−1 on variants fertilized with rotted farmyard manure and liming. This research is a valuable source of information for potato growers and scientists from this region as the results have shown how fertilization is raising productivity in this environment and its importance in the future potato growing on acid soils in mountainous regions of Montenegro and Western Balkans.
