Conduction block and thin and hypokinetic myocardial segments in feline hypertrophic cardiomyopathyCase ReportY Sung, J Park, Y Chae, T Yun, BT Kang, H KimVet Med - Czech, 2025, 70(8):302-306 | DOI: 10.17221/14/2025-VETMED A 12-year-old castrated male domestic shorthair cat was referred for respiratory distress. Physical examination revealed a systolic heart murmur at the left apex and crackles in all lung fields. Thoracic radiography showed Valentine-shaped cardiomegaly, pulmonary oedema, and pleural effusion. Echocardiography revealed focal thickening of the interventricular septum [11.01 mm; reference interval (RI) = 3.00–5.20 mm] and left ventricular posterior wall (7.41 mm; RI = 3.00–5.10 mm) during diastole. In the apex region, the free wall was focally thinned to approximately 1.6 mm with hypokinetic myocardial movement, indicating thin and hypokinetic myocardial segments. Additionally, decreased left atrial fractional shortening (12.5%; RI = 23.9–34.9%) and an increased left atrial-to-aortic ratio (2.87; RI = 0.88–1.43) were observed, along with spontaneous echocardiographic contrast in the left atrium, indicating increased thrombotic risk. The electrocardiogram showed a left axis deviation with small R waves and deep S waves in lead II, which is consistent with a left anterior fascicular block caused by delayed conduction in the left anterior fascicle. This case report describes the coexistence of a left anterior fascicular block and thin, hypokinetic myocardial segments in feline hypertrophic cardiomyopathy, suggesting a possible pathophysiological link. |
Development of sessile oak [Quercus petraea (Matt.) Liebl.] seed coating material against rodents and evaluation of its performance on seed germination and emergenceOriginal PaperMesut Tandoğan, Mehmet Özdemir, Vedat Aslan, Ahmet F. Hacıyusufoğlu, Ali Ayhan Kul, Emine ªen, Kaan Polatoğlu, Duygu Sultan OranJ. For. Sci., 2025, 71(9):417-425 | DOI: 10.17221/42/2025-JFS Protecting sessile oak [Quercus petraea (Matt.) Liebl.] seeds from rodents is crucial to ensure successful germination and emergence in activities such as artificial regeneration, afforestation, and seedling production. This study examined the effects of 12 natural or nature-identical substances, believed to have repellent properties, on the germination, emergence, and survival of sessile oak acorns under both laboratory and field conditions. Acorns were coated using a diatomaceous clay-based pellet system, and a Y-maze experiment was conducted to evaluate rodent behaviour. As a result of the research, among the tested substances, Ferulago confusa and Foeniculum vulgare were recommended as rodent repellents due to their success in laboratory and field trials. Diesel fuel + hair, a conventional repellent, showed poor performance and is not recommended. This study underscores the potential efficacy of natural or nature-identical coatings for protecting seeds from pests in forestry applications. |
Impact of the adoption of chemical inputs on crop yield downside riskOriginal PaperOlha Aleksandrova, ©tefan BojnecAgric. Econ. - Czech, 2025, 71(10):527-536 | DOI: 10.17221/298/2024-AGRICECON The study aims to analyse the impact of application of chemical inputs like fertilisers or crop protection products on farm crop yield productivity in Estonian and Slovenian agriculture. We combined the propensity score matching (PSM) method with an inverse probability weighted regression (IPWRA) model to derive treatment effects of the adoption of these critical inputs using Farm Accountancy Data Network data. Results exhibit consistency across estimation techniques. Estimates of both IPWRA and PSM models showed that adoption of at least one of the chemical inputs decreases volatility of crop yield output and downside risk. The results are more robust for Estonian than for Slovenian farms suggesting on possible impacts of other exogenous factors such as climate change on mitigating the crop yield downside risk. |
Coagulation profile in bitches with pyometra: Standard tests and thromboelastographyOriginal PaperA Ramesova, K Machackova, I Vanova, M Lacinova, A Bartoskova, R Novotny, R Vitasek, K Rehakova, J DoubekVet Med - Czech, 2025, 70(11):408-416 | DOI: 10.17221/16/2025-VETMED This study aimed to determine coagulation changes in bitches with pyometra based on a series of coagulation tests and thromboelastography (TEG), and to assess the incidence of disseminated intravascular coagulation (DIC). Eighteen bitches with pyometra and thirty-four control bitches were examined. Haematological, biochemical, and following haemostasis parameters were measured, including: prothrombin time (PT), activated partial thromboplastin time (aPTT), antithrombin activity (AT), and levels of fibrinogen (FBG), d-dimers (DD), tissue factor (TF), plasminogen (PLG), tissue plasminogen activator inhibitor 1 (TPAI-1), and thromboelastography. DIC was considered present if three or more of these parameters were abnormal: platelet count (<153 × 109/l), PT (>8.1 s), aPTT (>25.5 s), FBG (<0.6 g/l), DD (>0.2 mg/l), and AT (<107%). Significant differences were found in the PT, aPTT, FBG, DD, TPAI-1, clotting time, α-angle, and maximal amplitude. According to our scoring system, two patients were DIC positive. The study found alterations in several coagulation tests and hypercoagulable TEG tracings in bitches with pyometra, which point to excessive activation of coagulation, delayed fibrinolysis, and the presence of DIC. No patient bled abnormally, which may suggest that DIC is not overt in the majority of pyometra patients. |
Occurrence of herbicides and their transformation products in sewage sludge: a reviewReviewMadhusha Mihirani Subasinghe, Filip Mercl, Sreynet Nang, Altyn Taisheva, Pavel Tlusto¹Plant Soil Environ., 2025, 71(12):849-859 | DOI: 10.17221/485/2025-PSE The beneficial reuse of sewage sludge in agricultural soils is limited by the accumulation of micropollutants of emerging concern, which may pose significant environmental and human health risks. This review summarises recent advances in understanding the occurrence, persistence, and fate of herbicides and their transformation products in sewage sludge. Data from various geographic regions are discussed, with a focus on implications for the safe reuse of biosolids in agriculture. Most available studies have been conducted in European Union countries, where land application of biosolids is a common practice. Twelve groups of herbicides and their transformation products have been identified in sewage sludge, including glyphosate and aminomethylphosphonic acid (AMPA), phenylureas, phenoxy acids, chloroacetamides, triazines and their metabolites, triazinones, phenylcarbamates, isoxazolidinones, benzoic acids, dinitroanilines, benzofurans, phenyl ethers, and other herbicides. Among these, triazines and their metabolites were the most frequently detected, with concentration ranges of 0.01–277 ng/g and not detected (n.d.)–237 ng/g, respectively. Glyphosate and AMPA were found at particularly high concentrations (n.d.–35 000 ng/g). Phenylurea herbicides (e.g., diuron and isoproturon) were detected in a limited number of studies, with concentrations ranging from not detected to 102 ng/g. Substantial concentrations of phenoxy herbicides (2,4-d, 2,4-db, and 2,4,5-t) were also reported in sewage sludge, ranging from 50.5–864 ng/g. The available scientific literature on the occurrence of herbicides in sewage sludge focuses mainly on older, often already banned compounds, while data on currently approved herbicides remain scarce. This review highlights the need for more comprehensive global assessments of herbicides and their transformation products in sewage sludge to ensure the safe agricultural use of biosolids and minimise risks to plants and other organisms. The current lack of systematic monitoring and documentation represents a critical knowledge gap in evaluating environmental exposure and associated risks. |

Genomic SSR marker development in lentil (Lens culinaris Medik.) and assessment of cross-species/genera transferability to related legumesOriginal PaperMelike Bakır, ªehriban Demir, Cebrail Yıldırım, Abdullah KahramanCzech J. Genet. Plant Breed., 2024, 60(1):42-49 | DOI: 10.17221/57/2023-CJGPB Simple sequence repeat (SSR) markers are valuable genetic and genomic research tools and are extensively used in major crops. However, a paucity of available molecular markers in lentils (Lens culinaris Medik.) has significantly hindered genomic studies in this vital legume crop. In this study, we developed 33 new SSR markers for lentils using an enriched genomic library and tested their polymorphism in 10 lentil cultivars. We found that 16 (48.5%) SSR markers were polymorphic. The expected heterozygosity values of the polymorphic SSR markers ranged from 0.095 to 0.820, while observed heterozygosity values varied between 0.100 and 1.00. In addition, we tested the transferability of 86 SSR markers, including the 33 newly developed ones, to other legume species. Transferability rates of lentil SSR markers to other species varied between 13.76% (Vicia sativa L.) and 2.58% (Phaseolus vulgaris L. and Trifolium pratense L.). These new SSR markers could be used in further molecular breeding, population genetics, and genetic mapping studies in lentils and other legume species. |

Controlling Phytophthora blight of pepper in Guizhou Province of China using Stellera chamaejasme extracts and synthetic chemical fungicidesOriginal PaperJiling Dang, Xingren Shi, Yuquan Lin, Mark L. Gleason, Jia FengPlant Protect. Sci., 2024, 60(1):53-64 | DOI: 10.17221/84/2023-PPS Phytophthora blight of pepper, caused by Phytophthora capsici Leonian, is a destructive disease in pepper production. Extracts of the plant species Stellera chamaejasme Linn, previously known in China as a source of herbal medicine, were also used in former years as a toxin against aphids, mites, and plant-pathogenic fungi. Extracts of S. chamaejasme (SC) and seven commercial fungicides were investigated for their inhibition of mycelial growth and germination of cysts of the pathogen in vitro. The SC alone, infinito (fluopicolide + propamocab + hydrochloride), fluazinam, dimethomorph, and their mixtures with SC strongly inhibited both mycelial growth and germination of cysts of P. capsici. Tests were conducted in a commercial field in Fenggang County, Zunyi City, Guizhou Province, China, in 2019, 2020, 2021, and 2022 to validate these results for growers. A soil application (7 days before transplanting) and three foliar sprays at 7, 10, or 15 days were tested. One soil application of SC followed by three successive foliar sprays of infinito, fluazinam, and dimethomorph at 7- or 10-day intervals, as well as tank-mixed applications of these synthetic fungicides with SC at 15-day intervals, limited Phytophthora blight incidence to < 10% on the non-treated control treatment. Disease incidence was limited to < 3% to < 5% when alternating SC, SC + infinito, SC + fluazinam, and SC + dimethomorph three times at 7-, 10- or 15-day intervals, plus one soil application of SC. When treatments were applied from early April to May, disease incidence was < 10% in the non-treated control during June and July. The optimal concentration of SC was determined to be 0.25 g/L, which effectively controlled Phytophthora blight and protected marketable yield. SC also significantly (P < 0.05) outperformed treatments in a nearby commercial pepper field that relied on applications of a single synthetic chemical fungicide. The findings of this study provide a foundation for guiding growers to implement an efficient and environmentally safe spray program against Phytophthora blight of pepper in Guizhou Province. |

Can income growth and environmental improvements go hand in hand? An empirical study of Chinese agricultureOriginal PaperChenchen Su, Jinchuan Shen, Fei WangAgric. Econ. - Czech, 2024, 70(7):321-333 | DOI: 10.17221/438/2023-AGRICECON Advancing agricultural carbon emission efficiency and farmers’ income simultaneously is crucial for the sustainable progress of agriculture. Our study centered on 31 provinces and cities in China and investigated regional variances and the dynamic evolution aspects of coordinated development in farmers’ income and agricultural carbon emission efficiency, utilising panel data from 2005 to 2021. The analysis revealed the following trends: Firstly, China’s overall agricultural carbon emission efficiency was steadily increasing, mainly because of technological advancements. Secondly, the correlation between farmers’ income and agricultural carbon emission efficiency in China had notably improved from 0.318 to 0.775. Throughout the observation period, disparities in the levels of coordinated development were observed in various provinces with a diminishing fluctuation, indicating regional disparities as the primary instigator. Thirdly, the level of coordinated development highlighted positive clustering attributes, demonstrating an ‘east high, west low’ pattern; the evolution of coordinated development levels exhibited stability in maintaining the current status. This study holds significant value for developing countries in enhancing farmers’ income and agricultural carbon emission efficiency in a coordinated manner. |

Optimising sunflower yields: insights from meta-analysis on fertilisation impact and planting strategies for enhanced crop productivity in ChinaOriginal PaperShun Li, Zongqing LiuPlant Soil Environ., 2025, 71(1):48-57 | DOI: 10.17221/303/2024-PSE Sunflower serves as a valuable rotational crop, suitable for snack processing or sunflower seed oil extraction, proving to be a lucrative cash crop. To address sunflower yield uncertainties, this study employs meta-analysis to examine the impact of fertilisation. Utilising 41 studies and 392 pairs of observations based on four criteria, we found an overall 27% increase in sunflower yield with fertiliser application. Nitrogen (N), phosphorus (P), and potassium (K) individually applied raised yield by 23.37, 20.92, and 11.63%, respectively. Combined fertilisers (NP, NK, NP, and NPK) enhanced yield by 29.69, 28.40, 17.35, and 41.91%, respectively. Sunflower type minimally affects yield, while planting density significantly influences it. Combining local soil conditions and environmental factors with appropriate planting densities ensures maximum sunflower yield, fostering economic benefits for farmers. This study holds constructive implications for sunflower cultivation in China, contributing to increased yield. |
The role of seed transmission in the spread of cereal viruses: Global challenges and prevalent threats in UkraineReviewHalyna Snihur, Tetiana Shevchenko, Oleksiy Shevchenko, Anhelina KyrychenkoPlant Protect. Sci., 2025, 61(3):201-221 | DOI: 10.17221/51/2025-PPS The transmission of plant viruses through seed plays a fundamental role in virus spread, persistence, and survival, particularly in economically important crops. Besides its considerable ecological significance, seed transmission influences plant and virus evolution. Virus contamination of the seed also has critical epidemiological implications, especially when combined with subsequent or additional insect vector spread. Plants grown from contaminated seeds serve as primary viral inoculum sources, facilitating the introduction of viruses into new regions and triggering disease outbreaks with substantial economic losses for growers. Changes in environmental conditions increasingly influence plant virus epidemiology by affecting vector populations, host susceptibility, and transmission dynamics, thus increasing virus transmission risks in cereal crops. This review explores the mechanisms of seed transmission and its consequences, with a focus on key cereal viruses in Ukraine: barley stripe mosaic virus, wheat streak mosaic virus, High Plains wheat mosaic virus, sugarcane mosaic virus, and maize dwarf mosaic virus. Hereby, the biological properties of these viruses, the risks posed by seed transmission, and the economic impact on crop production are discussed. Given the widespread distribution of these pathogens, presented data will also be valuable for other cereal-growing regions, particularly those bordering Ukraine and engaged in seed import/export. This review underscores the global need to manage seed-transmitted viruses to safeguard cereal crop productivity and food security. Future research should focus on developing resistant cultivars and advanced diagnostics to control their spread. |
Prevalence and risk factors of Cryptosporidium spp. and Giardia infestation in cattle and in broiler chickens in AlgeriaOriginal PaperR Baazizi, M Taibi, N Senouci, D Baroudi, S Khodja, R Belala, D Khelef, N MimouneVet Med - Czech, 2025, 70(2):68-76 | DOI: 10.17221/82/2024-VETMED Cryptosporidiosis and giardiasis are zoonotic protozoan diseases with significant public health and economic concerns. In Algeria, epidemiological data on these parasites in livestock are limited. This study aimed to estimate the prevalence of Cryptosporidium spp. and Giardia in dairy calves and broiler chickens and to identify the associated risk factors. A microscopic analysis of 200 faecal samples revealed a Cryptosporidium spp. prevalence of 56% in calves and 60% in broiler chickens, while the Giardia prevalence was 8% in calves and absent in chickens. In cattle, the data showed that age constituted a potential risk factor for both parasites (P < 0.000 1 for Cryptosporidium; P < 0.000 5 for Giardia). Interestingly, the risk of a Cryptosporidium infection decreased with age, while the Giardia infestation risk increased. The sex was not a significant factor for Cryptosporidium (P = 0.115 0), but was impactful for Giardia (P < 0.000 1), with males at higher risk. These results highlighted the distinct epidemiological characteristics of Cryptosporidium and Giardia infestations in Algerian livestock. The contrasting age-related risks and sex-specific susceptibility to Giardia underline the need for targeted, age and sex prevention strategies. This study provides valuable data to inform public health policies and to improve livestock management practices in Algeria, contributing to the wider understanding of these zoonotic parasites in North African agricultural farming. |
Biocontamination in the dairy industry: The effect of raw milk conditioning film on the adhesion of Escherichia coliOriginal PaperZakariyae El hafa, Ikhlas Hani Chennoufi, Hafida Zahir, Mostafa El louali, Hassan LatracheCzech J. Food Sci., 2025, 43(2):112-117 | DOI: 10.17221/91/2024-CJFS Conditioning films on surfaces employed in the dairy industry serve as the precursors to the formation of pathogenic biofilms that impact product quality and consumer safety. Conditioning films have been studied from several aspects. However, there has been no study that evaluated the effect of raw milk conditioning film on the adhesion of Escherichia coli. This study investigated the adhesion of E. coli on glass and stainless-steel surfaces conditioned with raw milk and explored the surface properties potentially influencing this adhesion using the contact angle method. The results showed that after treating surfaces with raw milk, the adhesion of the bacteria on stainless steel and glass was significantly altered. Adhesion increased significantly on stainless steel (from 0.55 log10 to 2.8 log10) but it decreased on glass (from 1.56 log10 to 0.8 log10). Significant alterations were observed in the physicochemical properties of the surfaces. Glass was initially relatively hydrophilic (46.33°), while stainless steel was relatively hydrophobic (82.5°). After treatment, the glass became relatively more hydrophobic (74.6°), and stainless steel became relatively more hydrophilic (69.4°). The electron donor/acceptor components of glass decreased after the treatment, while these components increased for stainless steel. The significant changes in adhesion were hypothesized to be due to the modification of surface properties by the raw milk. |
The potential of probiotics derived from functional foods for skin healthReviewEunhye SonCzech J. Food Sci., 2025, 43(4):235-245 | DOI: 10.17221/35/2025-CJFS Probiotics, widely recognised for their benefits in gut health, have gained increasing attention for their comprehensive role in skin health maintenance and improvement. This review explores the multifaceted impact of food-derived probiotics on various aspects of skin health, including anti-aging, inflammation regulation, barrier function enhancement, and hydration. Probiotics exert protective effects against oxidative stress and inflammatory responses through modulation of the gut-skin axis, enhancement of the skin microbiome balance, and immunomodulatory properties. Additionally, functional foods enriched with probiotics have demonstrated efficacy in promoting skin hydration, elasticity, collagen production, and overall resilience. By synthesising recent research findings, this review highlights the potential of probiotic-enriched foods as a natural approach to supporting comprehensive skin health and addressing age-related skin changes. The implications for functional food development and dietary interventions are also discussed, providing insights into future research directions in probiotic-based holistic skin care strategies. |

Unveiling green perception effect: How live streaming scenes and green information influence purchase intention of prepared dishesOriginal PaperShuo Hao, Pei Li, Nannan Zhang, Yang Du, Rui Liang, Ziyang LiuAgric. Econ. - Czech, 2025, 71(10):537-549 | DOI: 10.17221/247/2024-AGRICECON To promote the sustainable consumption of prepared dishes, this study examines how green attribute information (GAI) and live streaming scenes experience (LSSE) influence consumers' green perceptions (GP) – including perceived green value (PGV) and perceived green trust (PGT) – and subsequently affect their purchase intention (PI). A green perception model was developed and tested using a mixed-method approach. Word cloud analysis was conducted on consumer comments collected from e-commerce platforms to extract key descriptors and concerns, which informed the design of a structured questionnaire. A total of 291 valid responses were analysed using partial least squares structural equation modelling (PLS-SEM). Results show that: (i) GAI does not directly impact PI, indicating that GP is a necessary mediator; (ii) GAI significantly influences PGV, but not PGT; (iii) GP fully mediates the GAI–PI relationship, although PGV has a negligible direct effect on PGT; (iv) LSSE significantly enhances both GP and PI; (v) GP partially mediates the LSSE–PI relationship. These findings highlight the dual role of LSSE in facilitating information adoption and emotional engagement, and suggest that enhancing LSSE design and enriching GAI are effective strategies to increase consumers' green perception and purchase intention towards prepared dishes. |
Detection of heat-stressed chickens in poultry house based on deep network and optical flow vectors in the Fourier domainOriginal PaperNgo Quoc Viet, Thai YenRes. Agr. Eng., 2025, 71(4):189-199 | DOI: 10.17221/46/2025-RAE The productivity and quality of the entire flock are negatively impacted by heat stress in chickens, which can have major repercussions, particularly in crowded farming settings where diseases are easy to spread and hard to control. This study uses deep networks and optical flow to identify heat stress in chickens. The technique focuses on identifying obvious signs of heat stress, such as panting and open-mouth breathing in chickens. There are two phases to the suggested approach: (1) using a deep network to detect open-mouth breathing in chickens; (2) using the Gunnar Farnebäck algorithm to compute the optical flow vectors of the wattle, the breathing frequency is estimated in the Fourier domain for the detection of panting chickens. The proposed method was tested on the obtained dataset and demonstrated its ability to recognise heat-stressed chickens in crowded conditions, achieving an overall performance metric of 0.90 by integrating the results of both phases. The two-phase approach, which incorporates the open-mouth breathing behaviour and panting frequency, improves the efficiency and assures robust, reliable heat stress detection. |
A comparative applied analysis of six robotic-assisted weeding systems in sugar beetsOriginal PaperSonja I. Kimmel, Matthias Schumacher, Michael Spaeth, Markus Sökefeld, Oyebanji O. Alagbo, Alicia Allmendinger, Dionisio Andujar, Therese W. Berge (ORCID: 0000-0002-8780-Plant Soil Environ., 2025, 71(11):782-792 | DOI: 10.17221/335/2025-PSE Effective weed management is crucial in the critical period of sugar beet production, but often lacks sustainability and environmental protection. Recent advancements in sensor-based weed control systems have rendered the latter a realistic prospect, which demands detailed analyses, especially under suboptimal field conditions. The present study analysed six robotic-assisted weed control systems (RAWS) in three experiments on sugar beets in 2024, conducted under dry soil and high weed pressure. The experiments included sensor-based inter-row and intra-row hoeing, spot- and band-spraying and were compared to a broadcast herbicide treatment and an untreated control. Weed control efficacy (WCE) in the intra- and inter-row areas, as well as weed species composition and crop plant damage, were assessed after treatment. The data show that intra-row WCE of two hoeing robots (Farming GT® and Robovator®) equipped with selective intra-row blades achieved up to 80%, which was higher than the broadcast herbicide control with 67% WCE. In the inter-row area, Farming GT® robotic hoeing and ARA® spot-spraying resulted in more than 90% WCE, which was equal to the broadcast herbicide application. Weed species composition was not affected by the different RAWS. Crop plants were affected by all hoeing treatments with maximum non-lethal burial rates of 33%. The highest lethal uprooting of crop plants occurred after Farming GT® robotic hoeing, at 5.5% overall. The results demonstrate the great potential of robotic weeding to replace broadcast herbicide applications. |
Enhancing rheological properties of dough and quality of potato fibre-enriched breadOriginal PaperOmar Saleh, Hossam S. El-Beltagi, Abdelrahman R. Ahmed, Hefnawy Taha, Haiam O. Elkatary, Abdalla El‐Hadary, Hoda A.S. Farag, Mahmoud Sitohy, Ahmed Mahmoud Ismail, Ali OsmanCzech J. Food Sci., 2025, 43(6):462-469 | DOI: 10.17221/29/2025-CJFS This study investigates the effect of varying concentrations of potato fibre (PF) (1, 2, and 3%) on wheat flour (WF) dough rheological properties and the resultant pan bread quality. Chemical analysis, physical characteristics (weight, loaf volume, and specific volume), and colour attributes were estimated to assess bread quality. The impact of PF on bread sensory evaluation was estimated. The addition of PF significantly affected the properties of the dough. Moreover, the data indicated a substantial increase in water absorption (P ≤ 0.05) from 57.2% for the control to 65.5, 73.3, and 77.6% with the addition of 1, 2, and 3% PF to WF, respectively. Protein, crude fibre, and ash levels significantly increased (P ≤ 0.05) with higher PF ratios. Moisture and carbohydrate contents were markedly reduced (P ≤ 0.05). The specific volume considerably decreased from 3.15 cm3·g–1 in the control to 2.9, 2.74, and 2.53 cm3·g–1 with the addition of 1, 2, and 3% PF to WF, respectively. All replacement samples exhibited no significant alterations (P ≤ 0.05) in L* values and substantially (P ≤ 0.05) increased values of yellowness (b*) in all fortified samples relative to the control. Sensory assessments revealed that PF can be incorporated into WF at concentrations of 1% and 2% without compromising the overall acceptability of bread compared to the control. |
Closed-circle bioeconomy: Applied aspects of agricultural implementationReviewYelizaveta Chernysh, Viktoriia Chubur, Miroslav Hájek, Hynek RoubíkAgric. Econ. - Czech, 2025, 71(12):680-690 | DOI: 10.17221/36/2025-AGRICECON In the face of global challenges, innovative methods of production and consumption are vital, and the bioeconomy signifies a transformational shift based on biological processes, minimal energy use and full integration of resources into ecosystems. This study focused on a sectoral analysis of bioeconomy opportunities with a focus on bioenergy and waste management in an agriculture sustainable approach. Literature-based analysis was used to approach the research objectives of the roadmap design methods. A comprehensive sectoral analysis of the bioeconomy was conducted with a special emphasis on bioenergy and food security. A conditional roadmap of bioeconomy implementation clusters was presented, which is in line with global trends. Agriculture, being an integral part of the bioeconomy, faces challenges due to ecosystem degradation, water scarcity, and poverty. The global trend of biotechnology adoption in agriculture offers benefits for sustainable bio-economic development, including soil conservation, cost reduction, job creation and improved food quality. Thus, the bioeconomy has significant potential to address global challenges and achieve sustainable development, which requires innovation, regional adaptation and a commitment to harmonise economic growth with environmental conservation. Further research into the involvement of the rural areas in the development of bioeconomy is required. |

Comparative study on the large-scale intensive culture of pikeperch (Sander lucioperca) larvae: Evaluation of two different live exogenous food optionsOriginal PaperVáclav Kuèera, Tomá¹ Pìnka, Oleksandr Malinovskyi, Carlos Yanes-Roca, Zhaxygali B. Kuanchaleyev, Tomá¹ PolicarCzech J. Anim. Sci., 2024, 69(6):243-254 | DOI: 10.17221/42/2024-CJAS This study is focused on the comparison of production efficiency (growth, survival, and development) and economic evaluation of large-scale larvae culture in pikeperch (Sander lucioperca) using Artemia (Group A) compared to using rotifers and the subsequent combination of rotifers and Artemia (Group R) as a first exogenous feed following weaning and intensive culture of juveniles. Both experimental groups were stocked with the same initial density (100 pcs per litre) of larvae at 4 days post hatching (DPH). Each group was cultured in triplicate until 65 DPH. Assessed parameters included FBW (final body weight), FTL (final total length), SGR (specific growth rate), SR (survival rate), CR (cannibalism rate), SBI (swim bladder inflation rate), and TDR (total deformity rate). Production costs were confronted with total number of all produced and high-quality juveniles to determine the cost per one juvenile. Juveniles in Group A displayed more rapid growth (significantly higher FBW, FTL and SGR). On the other hand, parameters concerning quality of the fish (SBI, SR, Share of high quality juveniles and TDR) were significantly higher in Group R. Statistical difference in CR also benefits Group R. Production of bigger share of high-quality juveniles in Group R decreased overall production cost per one high-quality juvenile by 59.7%, from 0.72 EUR in Group A to 0.29 EUR in Group R. Use of established feeding protocols confirmed significant production and economic improvements in pikeperch larvae culture and production of high-quality juveniles. Even though the price of rotifer cultivation significantly exceeded the price of Artemia purchase and cultivation, the production cost of high-quality pikeperch juveniles significantly decreased. |
Assessment of agricultural land salinization via soil analysis and remote sensing data: Case study in Pavlodar region, KazakhstanOriginal PaperDauren Rakhmanov, Boøivoj ©arapatka, Kamilla Alibekova, Jan Èernohorský, Petr Hekera, Zhassulan SmanovSoil & Water Res., 2024, 19(2):111-121 | DOI: 10.17221/5/2024-SWR Soil salinization is one of the most widespread soil degradation processes, especially in arid and semi-arid regions. In such climatic conditions, soluble salts accumulate in the soil, leading to deterioration in soil properties and ultimately reduced crop yield. The purpose of this study was to analyse the relationship between the level of soil salinity and the main spectral indicators obtained from Landsat satellite data. The studied area was the Maisky district, which is located in the southeastern part of the Pavlodar region of Kazakhstan. The variants of the research were agricultural lands using sprinkler irrigation and flood irrigation, as well as sites without irrigation. To analyse the relationships, we used the normalized difference vegetation index (NDVI), salinity indices (SI) and soil indices such as SI 1, SI 2, SI 3, SI 4, normalized difference salinity index (NDSI), soil adjusted vegetation index (SAVI), and brightness index (BI). The normalized difference salinity index (R-NIR)/(R + NIR), using a quadratic statistical relationship, showed the best correlation with the laboratory data. The vegetation index NDVI showed the weakest correlation due to dryness or poor crop growth. As a result of the lack of clear control over irrigation and agrotechnical measures, the indicators of cation exchange capacity in irrigated plots using the flooding method were higher than in other irrigation methods. During irrigation, it is necessary to ensure clear rules, according to which the supplied water and fertilizers will have a positive effect on the soil and the entire agroecosystem. The methods used in this research can be useful in mapping and studying saline soils using satellite data in natural and climatic conditions of arid and semi-arid regions. |
