A cross-sectional survey was carried-out to investigate the occurrence and associated risk factors for digestive parasite infections in water buffaloes (Bubalus bubalis) calves, in Center Romania. For this, individual fecal samples were collected, from a total of 63 calves and tested for protozoan and helminth infection by using standard qualitative (flotation) and/or quantitative (Mini-Flotac) copro-microscopic techniques. Overall, 77.8% [95% CI: 63.58-87.03] of the tested animals were positive for at least one parasite infections, either as single (53.9%; 95% CI: 38.03-65.35) or mixed (23.8.0%; 14.39-38.38) infections. Of the positive animals, 13.4% showed diarrhoea and all were with mixed infections. Among the parasites detected, the most frequent was Eimeria spp. (68.2%), followed by Toxocara vitulorum (15.9%), Giardia duodenalis (14.3%), and Strongyloides papillosus (4.2%). These findings showed the presence of parasites that may seriously impact the animal health, some of them with zoonotic potential. Altogether the results of this study emphasize the requirement for specific measures for control parasite infections in water buffalo farms.

The paper presents aimed research results of the density level effect on quinoa plant development, yield and yield components to ensure maximum efficiency of crop rowing under regional conditions. Research was carried out for 2020-2022 in area of North-Eastern Forest-Steppe of Ukraine with the quinoa variety of Quartet. Several sowing rates 0.8; 1.2; 1.6 and 2.0 million seed per ha) were studied. According to the results a continuous sowing technology with a sowing rate of 1.6 million similar seeds per ha is recommended. It provides a pre-harvest density of 1.37 million plant/ha and yield of 2.12 t/ha. Development and formation of the main crop of seeds ensures the main inflorescence of the central stem. The average yield index and weight of 1000 seeds were 27.9% and 2.82 g, respectively. For obtaining larger seeds (1000 seed weight > 3.0 g), it is advisable to reduce the sowing rate to 1.2 million seed/ha. Yield shortage at this sowing rate in some years can be up to 0.08 t/ha.

Five Romanian winter wheat genotypes were analyzed during two experimental years (2019-2020) under four different regime fertilizers for chlorophyll a, chlorophyll b and carotenoid contents from flag leaf, respectively, number of grains/spike, weight of grains/spike, thousand kernel weight. The results showed that the application of additional fertilization increase the analyzed traits, also causing an increase of traits variability. Regarding the variation of photosynthetic pigments from flag leaf as an effect of different fertilizer levels, their concentration is specific to each variety. The highest value of chlorophyll a type is observed in Cezara variety (665.83 mg/kg DW) at N150 kg s.a./ha fertilization level applied in a boot stage. The variation of chlorophyll b concentration in flag leaf is similar to chlorophyll a concentration as a reaction of different nitrogen dose aplication, the highest value for this type of chlorophyll being registered in T. 109-12 at F4 (519.64 mg/kg DW). Carotenoid concentration from flag leaf varies from 3.93 mg/kg DW at Dumitra variety (F3) to 97.63 mg/kg DW at Andrada variety in F2 fertilization level.
在两个试验年（2019-2020 年）期间，对 5 个罗马尼亚冬小麦基因型在 4 种不同施肥制度下的叶绿素 a、叶绿素 b 和类胡萝卜素含量、粒数/穗、粒重/穗、千粒重分别进行了分析。结果表明，施用额外肥料会增加所分析的性状，同时也会导致性状变异的增加。关于不同施肥量对旗叶光合色素的影响，每个品种的光合色素浓度都不同。叶绿素 a 类型的最高值出现在 Cezara 品种上（665.83 毫克/千克干重），施肥量为 150 千克标准/公顷，施肥期为引导期。旗叶中叶绿素 b 浓度的变化与叶绿素 a 浓度的变化相似，都是对不同氮肥剂量的反应，叶绿素 b 的最高值出现在 T. 109-12 F4 期（519.64 毫克/千克干重）。在 F2 施肥水平下，旗叶类胡萝卜素浓度从 Dumitra 品种（F3）的 3.93 毫克/千克（干重）到 Andrada 品种的 97.63 毫克/千克（干重）不等。

We studied the long-term population dynamic`s (2005-2020) of six main insect pests of winter wheat (late wheat shoot fly, hessian fly, frit flies, cereal beetles, corn ground beetle and sun pest) in three climatic zones of Ukraine under conditions of increasing areas of application pesticides and global warming. The aim of the research was to investigate how these factors influence pest population dynamics. Comparison of sums of effective temperatures (SET) with standard values for different zones indicates significant climate warming over the past 15 years. Correlation analysis with two variables showed a general decrease in the numbers of most populations, especially in the steppe and forest-steppe zones.

Several field trips were carried out in 2022 and 2023, aiming to investigate the water quality parameters, ichthyofaunal and floristic diversity in some areas of Gurban Valley, located in the protected area Natural Park Comana, Giurgiu County, southern Romania. Throughout the study period were identified fish specimens belonging to nine species: Prussian carp Carassius gibelio (Bloch, 1782); Gobio obtusirostris Valenciennes, 1842; Dnieper chub Petroleuciscus borysthenicus (Kessler, 1859); Roach Rutilus rutilus (Linnaeus, 1758); Danubian spined loach Cobitis elongatoides Băcescu & Mayer, 1969; Belica Leucaspius delineatus (Heckel, 1843); Southern ninespine stickleback Pungitius platygaster (Kessler, 1859); European bitterling Rhodeus amarus (Bloch, 1782) and European mudminnow Umbra krameri Walbaum, 1792. A total of 147 captured specimens were measured, weighed and photographed. For the capture of fish, minnow traps and plankton nets were used, on the Gurban River, right tributary of the Neajlov River, Giurgiu County. The floristic inventory compiled so far included 58 plant species grouped into 31 families, with European, circumpolar, Eurasian, eurasiatic continental or cosmopolitan distribution. Related to physico-chemical characterization of water samples collected from four sampling points (SP), the results of laboratory analysis allowed to frame the water into quality classes and to evaluate if the water meets the requirements for aquatic organisms. Hence, on the basis of nitrite-nitrogen (N-NO2-) and nitrate-nitrogen (N-NO3-) water corresponds to Ist quality class, meanwhile chemical oxygen demand (COD), phosphate-phosphorus (P-PO43-) and ammonium-nitrogen (N-NH4+) allowed to associate water quality with IIIrd class. In addition, it has been found very significant correlations between electrical conductivity (EC) and total hardness (TH) with r=0.9230*** and between pH and TH with r=0.8821***, respectively.

In order to determine to what degree the different conditions affected the stability of certain triticale genotypes and to what extent they determined the effect of the genotype x environment interaction, 12 lines of winter hexaploid triticale were studied under contrasting growing periods. The results from the AMMI-analysis showed that the GxE interaction accounted for 14.8% of the total variation of yield, while four significant principal components could explain 96% of its variance. The PCA analysis demonstrate that the first component related to the action of the meteorological conditions during 2015/2016 and 2019/2020 growing periods, and had the highest effect on the interaction. The AMMI-based biplot graphs revealed that the behavior of the local check Kolorit and lines G2 and G7 was the most stable according to the different periods affecting the genotype x environment interaction, while G1, G6 and G11 also had lower interaction with the conditions of the environment, but only during certain periods. Such characteristics allowed involving these lines in testing under the varied soil and climatic conditions of Bulgaria.

To prevent crop losses from pathogens, new varieties with a broad genetic basis of group resistance should be introduced into the production process. The purpose of research was to describe the collection of soft winter wheat in terms of resistance to the most common diseases in the conditions of the southern forest-steppe of ukraine. 1406 samples of soft winter wheat (Triticum aestivum L.) From 33 countries were taken for research. The significant influence of the amount of precipitation and the level of hydrothermal coefficient (HTC) on the indicator of the number of susceptible samples of wheat to specific pathogens of soft winter wheat was established. Selection work has significantly influenced the creation of more stable varieties in recent years compared to the 70's of the twentieth century. The method of remote hybridization using foreign genes helps to obtain lines more resistant to specific pathogens of soft winter wheat. Creating a special collection of samples resistant to the most common diseases of soft winter wheat allows you to systematize the selection of parental lines on specific grounds.

Vegetables present high nutritional content, being rich in vitamins, minerals, dietary fibres, organic acids and antioxidant compounds. However, fresh vegetables are generally harvested seasonally, being available in their fresh form for short periods of time during the year, and are also highly perishable. Therefore, the necessity of preserving them for a longer period of time has been addressed, freezing becoming the main technique used in this scope, due to its ability to maintain the initial quality of the product. The aim of the present study was to determine the properties of several fresh vegetables in different moments during processing for freezing preservation, namely initial moment (fresh form), after blanching pretreatment, after freezing/thawing process. The vegetables that were studied during this study were green peas, green beans, broccoli, asparagus, oyster mushrooms, Agaricus bisporus mushrooms and eggplants. As quality indicators, the following were determined: acidity, aw, colour, total polyphenolic content, antioxidant activity and ascorbic acid content (where applied). The results showed varied values for the monitored parameters. Generally, significant differences were observed during processing, with increasing and decreasing values of the tested parameters depending on the tested sample and applied treatment.

Plants represent an inexhaustible source of organic substances, minerals, vitamins, and antioxidants, which the human body absolutely needs. The opportunity to capitalize on some indigenous plants and bee products in natural, biostimulating juices results primarily from the objective itself, that of obtaining competitive nutritional-therapeutic assortments, with a healthy c effect on consumers. The technology of preparing natural, bio-stimulating juices is not only relatively simple but also affordable. Also, the valorization of the by-products resulting from obtaining these biostimulating natural juices is another important element of economic efficiency. Taking into account their multiple sensory, nutraceutical, and economic characteristics, obtaining bio-stimulating natural juices from indigenous plants and bee products become a major imperative for improving the health status and quality of life for consumers, as well as for the practice of performing national agrotourism.

Mushrooms have been used for both culinary and medicinal reasons for a very long time. Mushrooms are useful as both a food and a medication due to their high nutritional, protein, vitamin, and phenolic content. The current research aims to determine the antioxidant activity and phenolic content of Hebeloma sinapizans. Multiple epidemiological research looked at the possible link between polyphenol consumption and cardiovascular illness. Antioxidant, antiplatelet, antiinflammatory, antilipidemic, and antihypertensive are the categories used to classify the actions of phenolic substances. HPLC was used to isolate the phenolic compounds (HPLC). Measurements of oxidative stress, total oxidant levels, and total antioxidant levels were all calculated with the use of Rel Assay kits. The mushroom's TAS, TOS, and OSI values were measured, and its gallic acid, chlorogenic acid, and cinnamic acid concentrations were identified. Due to its high levels of phenolic compounds, H. synapizans is thought to be a source of phenolic compounds. High TAS and TOS values and low OSI values indicate that the mushroom has antioxidant potential. As a result, it has been seen that H. synapizans can be a good source of antioxidants.
很早以前，蘑菇就被用于烹饪和药用。蘑菇因其营养、蛋白质、维生素和酚类物质含量高，既可作为食物，也可作为药物。目前的研究旨在确定 Hebeloma sinapizans 的抗氧化活性和酚类物质含量。多项流行病学研究探讨了食用多酚与心血管疾病之间可能存在的联系。抗氧化、抗血小板、抗炎、降血脂和降血压是酚类物质作用的分类。采用高效液相色谱法分离酚类化合物（HPLC）。氧化应激、总氧化剂水平和总抗氧化剂水平的测量都是通过使用 Rel Assay 试剂盒计算得出的。测量了蘑菇的 TAS、TOS 和 OSI 值，并确定了没食子酸、绿原酸和肉桂酸的浓度。由于酚类化合物含量高，H. synapizans 被认为是酚类化合物的来源。高 TAS 值和 TOS 值以及低 OSI 值表明这种蘑菇具有抗氧化潜力。因此，H. synapizans 可以作为抗氧化剂的良好来源。
