Agricultural applications in food production have great significance in alleviating the adverse influences of environmental stressors on grapevines. In this context, mulch applications are known as environment-friendly sustainable implementations for efficiently benefiting from limited water sources. Moreover, mulches have many other beneficial effects such as quality assurance, yield improvement, ripening modulation, soil amelioration, erosion prevention and weed control. Therefore the present investigations were performed in an arid ecological condition to reveal the effects of easily available organic mulch (straw) and synthetic mulch (plastic ground covering) on physiology and growth features of worldwide popular grapevine rootstocks (41 B, 99 R 44-53 M and Rupestris du Lot). Saplings of each rootstock variety were transplanted to experimental vineyard at the end of the winter season with the spacing of 1.5 x 3.0 m within and between the rows. Mulch applications were carried out at the transplanting date. Mulch applications provided significant water retention with the higher effect of organic mulch in the soil. Stomatal conductance, leaf temperature and chlorophyll content were generally increased due to mulching. They also significantly improved the leaf and shoot growth of the rootstocks in many cases. Finally, both two mulch applications could be recommended as modern techniques in viticulture to prevent the agricultural water loss and support the plant growth. However, the organic mulch could be employed for organic and/or sustainable grape production or areas where the straw is easily available as residues of animal production.
在粮食生产中的农业应用对缓解环境胁迫对葡萄的不利影响具有重要意义。在这种情况下，地膜应用被认为是环境友好的可持续实施，可以有效地从有限的水资源中受益。此外，地膜还具有许多其他有益作用，如质量保证、产量提高、成熟调节、土壤改良、防止侵蚀和杂草控制。因此，本研究在干旱生态条件下进行，以揭示易获得的有机地膜(秸秆)和合成地膜(塑料地膜)对世界上流行的葡萄砧木(41 B、99 R 44-53 M和Rupestris du Lot)生理和生长特性的影响。每个砧木品种的树苗在冬末移栽到实验葡萄园，行内和行间间距为1.5 x 3.0 m。在移栽当日进行地膜覆盖。地膜的应用提供了显著的保水效果，有机地膜在土壤中的效果更高。覆盖使气孔导度、叶片温度和叶绿素含量普遍升高。在许多情况下，它们也显著促进了砧木的叶和梢的生长。最后，这两种覆膜技术都可以作为现代葡萄栽培技术推荐使用，以防止农业水分流失，支持植物生长。然而，有机地膜可用于有机和/或可持续葡萄生产或秸秆容易作为动物生产残留物的地区。

The different sectors of the livestock industry play an important role in meeting the increasing demand for animal products in both Hungary and Croatia. The general objective of this study was to investigate and compare the efficiency of the livestock sectors in Croatia and Hungary using the Data Envelopment Analysis method. In this paper, the technical efficiency of the dairy, beef, broiler, sheep and goat, and pig sectors from 2014 to 2017 is investigated based on the Farm Accountancy Data Network database. This paper compared farms of different size classes based on the Standard Production Value for more detailed insights. Among the five main livestock sectors, Hungary performs better in terms of farm technical efficiency in the dairy and beef sectors, while Croatia has higher efficiency scores in the sheep sector. The performances in the pig and broiler sectors are almost the same in both countries. Moreover, in the Hungarian poultry, pig, sheep and goat sectors and the Croatian dairy, beef and pig sectors, the technical efficiency of small-sized farms is better than that of medium-sized farms.

There is growing evidence that a disturbed microbiota, a complex ecosystem, is associated with the development of numerous diseases, including arterial hypertension. This complex cardiovascular disease is the result of not sufficiently clear role that genetic and environmental factors play in it. Not only does the treatment of hypertension include a drug therapy, but also it includes a variety of non-pharmacological measures based on dietary intervention. Probiotics and prebiotics are besides the nutrition the most commonly used substances that are aimed at maintaining a healthy microbiome or restoring the balance in case of disturbed bacterial homeostasis in disease. Although many studies have confirmed the effects of an imbalance in the gut microbiota (dysbiosis) in the last decade, the benefits of dietary intervention with probiotics in people with hypertension need to be supported by stronger evidence and further clinical trials in order to be ultimately confirmed.

The southern green stink bug Nezara viridula (Linnaeus) is a polyphagous species that causes economic damages to many crops in Bulgaria. The aim of this study was to identify the parasitoid species that could suppress the populations of Nezara viridula . A lot of agricultural crops were inspected in the region of Plovdiv, Bulgaria, for the presence of egg parasitoids and imaginal parasitoids of the pest. Egg masses and adults of Nezara viridula were collected during the field surveys in 2019-2021 in Southern Bulgaria. The only parasitoid species emerging from adults of the green stink bug was Trichopoda pennipes (Tachinidae), which is reported for the first time in Bulgaria. The rate of parasitism at field conditions ranged from 2.83% to 35% in the different generations of the host. The egg parasitoids were from family Scelionidae – Trissolcus basalis (Wollaston), Eupelmidae – Anastatus bifasciatus (Geoffroy), and Encyrtidae - Ooencyrtus telenomicida (Vassiliev). It was found that at field conditions the rate of parasitism of the eggs in 2020 and 2021 was respectively 7.77% and 0.25% in May, 34.32% and 17.23% in June, 72.3% and 80.51% in July, and in August – reaching 100% and 89.79%.

The European Union dairy processing sector has an important position and role in processing food and drinks in EU28 concerning the share of turnover, value-added, and employment. Its products belong to the most imported and exported items, mainly in EU countries. The article aims to evaluate the competitiveness of the EU milk market with respect to pre-and post-milk quota elimination periods. In addition, the paper identifies similar characteristics of the EU dairy sector, including milk production and processing. Eurostat and FAOstat data from 2008-2018 were used. Based on the clustering of k-means, five groups of EU countries were distinguished. The clustering analysis reveals that the post-communist EU member states are characterised by similar levels of dairy processing industry characteristics. In addition, the article shows that the competitiveness of the dairy processing industry is higher in the old EU member states (Belgium, Germany, Ireland, Greece, Spain, France, Italy, Luxembourg, Netherlands, Austria, Portugal, Finland, Sweden and the United Kingdom). The results indicate that the abolishment of the milk quota has not induced visible changes in the clustering of characteristics of the dairy processing industry in EU countries.

The high level of competition in the world cinnamon market causes a downturn in Indonesian cinnamon exports in international market. In 2019-2020, sales of Indonesian cinnamon in international market have experienced a downward trend. This study aimed to analyse the trend of Indonesian cinnamon’s export value in international market in 2001-2020 compared to Sri Lanka, Vietnam, and China, as the main exporting countries, then analyse the factors influencing the export value of Indonesian cinnamon in the United States, the Netherlands, Brazil, Germany, and Thailand, as main destination countries in international market by adding spatial and competitiveness variables. This study utilized secondary data and time-series data. The data obtained in this study were collected from various data sources such as International Trade Centre, World Bank, WTO, UN Comtrade, Artnet, UNESCAP, Pacific Exchange Rate Service, and other publications related to this research. Data on the performance of Indonesian cinnamon in international market utilized HS 1996 with HS code 0906 (Cinnamon and cinnamon-tree flower) in the 2001-2020 range. The results showed that the exports of Indonesia's cinnamon in international market had a positive trend. Indonesia had a very strong comparative advantage, so the potential to increase Indonesia's market share was very open in international market. The model estimation results showed that trade costs had an insignificant effect on Indonesian cinnamon exports in international market, while other variables, namely the GDP of the importing countries, the GDP of the exporting countries, the exchange rate, population, and competitiveness had a significant influence.

Terminal heat stress leads to significant yield reduction in wheat. Thus, the determination of heat tolerant genotypes is of major importance in wheat breeding program. The present study was conducted at Shandaweel agricultural research station, Sohag, Egypt during 2019/2020 and 2020/2021 growing seasons, to evaluate twelve bread wheat genotypes under normal sowing (20 November) and late sowing (30 December) dates, the experiment set up as a randomized complete block design with three replications. Results revealed that late sowing (terminal heat stress) had a significant adverse impact on agronomic, physiological traits and grain carbohydrate content. The genotype Shandaweel 2, followed by Giza 171 and Sids 14 performed better than other genotypes for grain yield under the normal sowing. On the other side, Shandaweel 2 outperformed the tested genotypes under the late sowing. Based on heat susceptibility index (HSI), the cultivars Sids 12, Misr 2, Sakha 95 and genotype Shandaweel 2 showed HSI<1 and they can be labeled as heat tolerant genotypes, while Sids 14, Misr 1, Giza 171 and Misr 3 showed HSI>1 and they can be considered as heat sensitive cultivars. GGE biplot analysis and ranking of genotypes revealed that the new line Shandaweel 2 was the an ideal genotype in terms of yielding ability and stability and it was suitable for planting under normal and late sowing conditions, while Giza 171 was suitable for planting under the normal sowing. The GYT biplot and superiority index showed that Shandaweel 2 and Giza 171 had the best traits profile.

Sunflower is the most important oil crop in the Republic of Croatia. In the last two decades, it has been grown on average on 33,506 ha with a average grain yield of 2.66 t/ha. Weeds represent one of the most important causes of biotic stress, and their action is reflected in the competition for nutrients, water, light and space. The weed flora in sunflower crops in Croatia is extremely diverse, and we will most often meet: Polygonum persicaria L., Polygonum lapathifolium L., Ambrosia artemisiifolia L., Chenopodium polyspermum L., Amaranthus retroflexus L., Solanum nigrum L. emend Miller, Abutilon theophrasti Medik, Datura stramonium L., Xanthium strumarium L., Convolvulus arvensis L., Cirsium arvense (L.)

The aim of this study was to see how chilled sperm quality is affected by ejaculation frequency and its correlation to seminal plasma composition in INRA 180 rams. Five rams were collected at high (HFE) and low frequencies (LFE). For the high frequency, the rams were collected three times on the same day every three days for 18 days. In the low frequency collection, three consecutive ejaculates were collected once a week for four weeks. Ejaculates were collected at 20-minute intervals in either HFE or LFE. Semen characteristics, concentration of total protein, lipid, cholesterol and fructose in seminal plasma were assessed. Semen samples were extended in skim milk-based extender at 15 °C, then evaluated at different storage times (0, 8, and 24 h). Fresh sperm quality parameters, seminal plasma composition, and stored sperm quality were shown to be higher in LFE than in HFE and in the first and second ejaculates than in the third one. After 24 h of storage, sperm quality was correlated to seminal plasma components. In conclusion, the frequency of ejaculation has an effect on the fresh and stored semen quality as well as on seminal plasma composition in INRA 180 rams.

Five rams were collected at high (HFE) and low frequencies (LFE). For the high frequency, the rams were collected three times on the same day every three days for 18 days. In the low frequency collection, three consecutive ejaculates were collected once a week for four weeks. Ejaculates were collected at 20-minute intervals in either HFE or LFE.
