Considering the interest in the consumption of faba bean and study of antioxidants in natural food resources, methanol extracts of fourteen Vicia faba cultivars harvested from a two-year field experiment were studied for their phenolic compounds, proanthocyanidines, and antioxidant activities by the DPPH free radical scavenging assay, ABTS cation radical decolorization assay, ferric reducing antioxidant power (FRAP), cupric reducing antioxidant capacity (CUPRAC), and total reducing power (TRP). The results indicate significant differences among the populations in their content of polyphenols and proanthocyanidine, resulting in variations in antioxidant activity of seed extracts. The storage of V. faba mature seeds under uncontrolled, but identical conditions decreased the total phenol content and antioxidant properties. The total phenols were from 10.12 ± 0.19 to 18.53 ± 0.14 mg GAE g−1 DE (2021 year) and 19.52 ± 0.16 to 26.94 ± 0.34 mg GAE g−1 DE (2022 year). In the 2022 growing season, the DPPH free radical scavenging activity had higher values for all populations from 4.83 ± 0.002 to 6.17 ± 0.003 g mg TE g−1 DE. Hierarchical cluster analysis and principal component analysis obtained from antioxidative profiles grouped the samples into two major clusters. The first cluster consists of extracts of V. faba cultivars from the 2021 growing season, while the V. faba cultivars from the 2022 growing season are in second cluster. Tested cultivars can be used as a readily available source of natural antioxidants.
Susceptibility of grapevine cultivars to Eutypa lata in Serbia
(Uniwersytet Przyrodniczy w Lublinie, 2023-08-31) Živković, Sanja; Vasic, Tanja; Marković, Jordan; Jevremović, Darko
The species Eutypa lata is one of the most critical phytopathogenic fungi that presents a threat to vineyards by causing significant economic damage. This grapevine disease is hazardous because there is no adequate chemical protection, so after its progression, there is a decrease in yield and dieback of parts or whole infected shoots. There are also no grapevine cultivars resistant to this disease. For these reasons, in this paper, testing of the susceptibility of a pair of grapevine cultivars to this disease was carried out. The testing was performed under semicontrolled conditions and included six of the most economically essential grapevine cultivars in Serbia (Riesling italico, Cabernet Sauvignon, Cardinal, Rkaziteli, Pinot noir, and Prokupac). Testing was performed using 14 isolates of E. lata isolated in Serbia and two control isolates obtained from the INRA. For specific detection of isolates of Eutypa spp. included in the experiment, a specific pair of primers, Lata 1/Lata 2.2, was applied, and an amplicon of the expected size of approximately 385 bp was established in all isolates. In the conditions of the set experiment, of all of the domestic and foreign-tested grapevine cultivars, the local cultivar Prokupac showed greater resistance to the isolates. In contrast, the cultivars Riesling italico, Cabernet Sauvignon and Cardinal, Pinot noir showed sensitivity to the isolates of E. lata, but not to the same extent as the cultivar Rkaziteli, which proved to be susceptible.
Variability of Meadow Fescue Accessions and Productivity and Quality of their Polycross Progenies
(Institutul Național de Cercetare Dezvoltare Agricolă Fundulea, 2023) Babić, Snežana; Sokolović, Dejan; Radović, Jasmina; Andjelković, Snežana; Lugić, Zoran; Petrović, Mirjana; Zornic, Vladimir
The collection investigated included nineteen meadow fescue accessions, 16 wild populations, and 3 commercial cultivars. The first part of the experiment was performed in a plant nursery at a distance plant of plant 60x60 cm. The experiment was done as a randomized block design with 30 plants per accession. This part of the experiment aimed to determine values and variability for the studied traits (heading date, plant height, length of leaf and the number of generative and vegetative tillers per plant and dry matter yield per plant) in two productive years. Data processing was done by ANOVA analyses. The obtained results show that the studied accessions had significant within and among variability for all parameters. The number of generative tillers per plant, plant height and leaf length positively affected dry matter yield per plant. The highest dry matter yield per plant was observed for accessions: FP 1 and FP 4, but the best ratio between dry matter yield and number of vegetative tillers per plant, traits that influenced dry matter quality, was scored for accessions FP 8, FP 7, FP 3, FP 10 and FP 16. The second part of the trial investigated the productivity and biomass quality of the best 26 progenies selected from the polycross field and formed from the plant with the best performance from the nursery. They are tested in plots 5x2 m, as a randomized block design, in 3 replications. The most productive progenies with high biomass quality originated from accession FP 8, FP 3 and FP 13.
Yield and quality of lettuce (Lactuca sativa L.) depending on variety and type of nitrogen fertilizer
(Faculty of Food and Agriculture, United Arab Emirates University, 2023-06-01) Bošković-Rakočević, Ljiljana; Pavlović, Nenad; Mladenovic, Jelena; Marjanović, Miloš; Zdravković, Jasmina; Tošić
The aim of this research was to determine the effect of the application of different types of nitrogen fertilizer in five different varieties of lettuce on yield. The experiment was performed in the open field, in the spring cycle of growing during 2018 and 2019. The size of the base plot was 3 m2, and the trial was set up in a random block system. The trial covered the application of various forms of nitrogen fertilizers: ammonium sulphate, ammonium nitrate and urea. The applied nitrogen dose is 100 kg/ha (May 10th 2018 and May 8th 2019). Samples for the analysis of vitamin C and nitrate content, as well as yield determination, were carried out at the stage of the technological maturity of lettuce (60-62 days after seedling). The average weight of lettuce, depending on the variety, varied in the range of 211.3 g to 258.7 g. The use of ammonium nitrate resulted in the highest average weight of lettuce head (246.7 g), followed by the use of urea (238.9 g) and the lowest by the use of ammonium sulphate (221.0 g). The nutritional value of lettuce (vitamin C content) shows that depending on the applied form of nitrogen in the fertilizer, the highest content of vitamin C was determined by urea (10.86 mg/100 g), then ammonium sulphate (9.61 mg/100 g), and the lowest by ammonium nitrate (7.38mg/100g). The lower content of vitamin C was found in varieties of lettuce with red leaves compared to varieties with green leaves. The accumulation of nitrate in lettuce leaves directly depends on the variety and the applied fertilizer. The highest nitrate content was with ammonium nitrate (2355.6 mg/kg). The accumulation of nitrate in lettuce varieties with red leaves was higher compared to varieties with green leaves. Keywords: Lettuce, Nitrate, Vitamin C, Yield, Open field
Perennial forage legumes as an element of sustainable systems
(University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, 2023-08-31) Tomić, Dalibor; Stevović, Vladeta; Đurović, Dragan; Marjanović, Miloš; Madic, Milomirka; Pavlović, Nenad; Lazarević, Đorđe; Petrović, Mirjana; RADOVANOVIĆ Mirjana
In the current intensive systems of agricultural production, many important features, i.e., functions of the agroecosystem have been degraded and disrupted. The intensification of agricultural production inevitably leads to land degradation in terms of its physical, chemical, and biological properties. The increasing presence of monocultures, reduced crop rotation, and excessive use of mineral nutrients, lead to several negative phenomena in such agroecosystems. Along with efforts to reduce energy consumption, and environmental pollution, intensify sustainable agriculture systems, and maintain biodiversity, the possibility of increasing the area under perennial forage legumes should be considered. As nitrogen fixers, these plants are minimally fertilized with nitrogen fertilizers whose residues in the soil are lost by leaching, causing pollution of groundwater as well as surface watercourses. The introduction of perennial legumes in the crop rotation can provide numerous benefits, such as increased and more stable yields of protein-rich biomass, conservation, and repair of land resources, increased yield stability, better utilization of nutrients, water, and light, as well as weed, disease, and pest control. The introduction of legumes in production systems would limit the increasingly pronounced land degradation. In order to develop sustainable agriculture, market policy should recognize the value of products obtained from leguminous plants through certain agricultural policy measures.
