Multivariate assessment of soil quality across different land use types in the hilly terrain of the subtropics of IndiaOriginal PaperJitendra Kumar, Homehswar Kalita, Rajesh A. Alone, Nishant K. Sinha, Alka Rani, Dhiraj Kumar, N. K. Lenka, Rajan Bhatt, Mohamed A. Yassin, Mohamed A. Mattar, Fülöp Attila, Ali Salem, ZolSoil & Water Res., 2025, 20(3):178-194 | DOI: 10.17221/6/2025-SWR The unsustainable conversion of forest areas into agricultural land poses a serious danger to the soil eminence of Arunachal Pradesh’s environmentally delicate hilly topography. Understanding the impacts of this land-use change is crucial for preventing further degradation. This study aimed to develop soil quality indices (SQIs) for different land use types: natural forest (NF), current jhum cultivation (JC), fallow jhum land (FJC), and pineapple cultivation (PA). Samples of soil were taken at a depth of 0 to 15 cm and examined for 22 potential soil quality indicators, with 19 showing significant (P < 0.05) influence from land use, constituting the total dataset (TDS). Principal component analysis (PCA) was employed on TDS to identify the minimum data set (MDS), comprising dehydrogenase activity, diethylenetriaminpentahacetic acid (DTPA)-extractable iron, and bulk density, contributing 73%, 19%, and 8% to the overall SQI, respectively. Subsequently, different SQIs were estimated using linear/nonlinear and additive/weighted scoring functions. The results revealed substantial alterations in SQIs among the land use types, through NF exhibiting the highest soil quality. Notably, the nonlinear SQIs exhibited greater sensitivity to land use conversion compared to their linear counterparts, indicating their potential as a more robust tool for assessing soil quality changes. This study concludes that the transformation of land use in the hilly regions of subtropics of Arunachal Pradesh has led to the deterioration of soil quality. The proposed indexing framework, leveraging the sensitivity and clarity of nonlinear SQIs, can effectively evaluate and compare soil quality across different land use scenarios, thereby informing sustainable land management strategies. |
MaPep1 and MbPep1, as plant elicitor peptides in banana, confer resistance to banana blood disease caused by Ralstonia syzygii subsp. celebesensisOriginal PaperPraphat Kawicha, Ladawan Rattanapolsan, Ratri Boonruangrod, Yube Yamaguchi, Kusavadee Sangdee, Aphidech Sangdee, Thanwanit ThanyasiriwatPlant Protect. Sci., 2025, 61(3):262-277 | DOI: 10.17221/179/2024-PPS Peptides play regulatory roles in various plant development and defence processes. They function as molecular messengers that detect threats and trigger defence responses. This study aimed to identify the genes encoding endogenous plant elicitor peptide precursors (PROPEPs) in bananas and their role in inducing resistance to Ralstonia syzygii subsp. celebesensis (Rsc). Two precursor genes, MaPROPEP1 and MbPROPEP1, were discovered and predicted to encode the precursor proteins of elicitor peptides, namely, MaPep1 and MbPep1. Both elicitor peptides contained 23 amino acids of the active elicitor peptide, which activated innate immune responses in banana resistance to Rsc. The disease assessment was conducted by inoculating banana plants with Rsc isolate MY4101 using the root-stabbing method. The results demonstrated that MaPep1 and MbPep1 pretreatment enhanced resistance to banana blood disease, as indicated by reduced disease severity and the absence of wilting for 7 days after infection. The expression of the MaPROPEP1, MbPROPEP1, MaLOX7, and Pr-10 genes was evaluated using qPCR and found to be upregulated by MaPep1 and MbPep1 injection followed by Rsc infection in aboveground banana tissues within 7 days. These findings prove that MaPep1 and MbPep1 are members of the Pep family and exhibit conserved functions across various plant species. This approach may be used to develop strategies for enhancing disease resistance in banana cultivation. |
Animal models of autism spectrum disorder: Insights into genetic, structural and environmental modelsReviewD Chivchibashi-Pavlova, K BratoevaVet Med - Czech, 2025, 70(7):227-241 | DOI: 10.17221/87/2024-VETMED Autism spectrum disorder (ASD) is a group of human neurodevelopmental disorders with significant global prevalence. Deficits in social communication and interaction and repetitive, stereotyped patterns of behaviour characterise ASD. The aetiology of ASD is unclear, but several genetic and environmental risk factors, either alone or in combination, are implicated in its development. To date, the underlying pathogenic mechanisms of ASD remain incompletely understood due to its heterogeneity. To better understand the pathogenesis of ASD, various animal models have been developed. The use of animals in ASD research allows the exploration of the biological substrates of social behaviour, cognition, and reward sensitivity, which are key components of ASD symptoms. This review outlines the commonly employed animal models in ASD research and explores their applications and the associated challenges. |
Determination of aflatoxin M1 presence and concentration in Van Herby cheeseOriginal PaperMurat Akdağ, Tuncer ÇakmakCzech J. Food Sci., 2025, 43(4):255-262 | DOI: 10.17221/197/2024-CJFS Aflatoxins are considered the most toxic secondary metabolites of concern to food safety due to their wide distribution and high toxicity in foods and feeds. The aim of this study is to identify the prevalence of aflatoxin M1 (AFM1) in Van Herby cheeses (brined/dry salted). A total of 90 brined and dry salted Van Herby cheese samples offered for retail sale were analysed. The AFM1 level in the samples was determined by the chromatographic [High-Performance Liquid Chromatography (HPLC)/Fluorescent Detection (FLD)] method. Brined Van Herby cheese samples contained AFM1 in amounts ranging from < LOD to 0.573 ng·g–1 with a mean of 0.165 ± 0.206 ng·g–1, while dry salted Van Herby cheese samples contained < LOD to 0.017 ng·g–1 AFM1. The analysis of the prevalence of AFM1 in brined and dry salted Van Herby cheese samples was 17.78% (n = 8) and 2.22% (n = 1), respectively. In Van Herby cheese production, standardisation, quality improvement and food safety control procedures need to be used effectively and disseminated. In addition to good agricultural and storage practices to prevent mycotoxin formation, measures must be taken to prevent aflatoxin contamination in animal feed. These applications and systems will provide positive contributions in terms of total quality, nutrients and public health, as well as different advantages such as technological superiority. |

Physiological and biochemical bases of AMF-mediated antimony stress tolerance in Linum usitatissimum: enhancing growth, phytochemical production, and oxidative damage resilienceOriginal PaperAhlem Zrig, Shereen M. Korany, Hana Sonbol, Emad A. Alsherif, Foued Hammouda, Danyah A. Aldailami, Marwa Yousry A. Mohamed, Mohamed S. Sheteiwy, Maria Gabriela Maridueña-Zavala, Salma Yousif Sidahmed ElsheikhPlant Soil Environ., 2025, 71(9):650-665 | DOI: 10.17221/246/2025-PSE Antimony (Sb) pollution from industrial activities poses a severe global threat, particularly impacting valuable medicinal crops like linseed, which are highly sensitive to heavy metals. This study reveals the remarkable potential of arbuscular mycorrhizal fungi (AMF) as a sustainable solution to this challenge. Our research demonstrates that while Sb stress significantly impairs linseed growth and photosynthesis, it also triggers oxidative damage. AMF improved photosynthetic performance and water status, and notably enhanced the biosynthesis of crucial phytochemicals like phenolics, flavonoids, and citric acid. These compounds are vital for both plant defence and human health. Furthermore, AMF promoted the accumulation of essential detoxifying agents, leading to a better redox balance and significantly reducing Sb uptake and translocation by 47%. This dual action not only bolsters the plant’s tolerance to Sb but also enhances its medicinal value by boosting health-promoting bioactive metabolites. These promising findings underscore AMF’s dual role: a powerful tool for phytoremediation and a natural enhancer of phytochemical quality. Arbuscular mycorrhizal fungi provide a sustainable, nature-inspired approach to safely cultivate medicinal plants in environments contaminated with heavy metals, underscoring the vital role of plant-microbe interactions in alleviating environmental stresses. |
Influence of dietary coriander seeds and administration of Lactobacillus acidophilus on the performance of growing rabbits under subtropical climatic conditionsOriginal PaperSM Abdel-Raheem, MA Kobeisy, YA Gomaa, AMA Meligy, M Elalfy, MM FarghalyVet Med - Czech, 2025, 70(9):313-328 | DOI: 10.17221/104/2024-VETMED This study investigated the effects of coriander seed powder and Lactobacillus acidophilus solution (LAS) on the growth, nutrient digestibility, blood parameters, and intestinal health of growing rabbits under subtropical conditions. Forty Californian rabbits, aged 35 days with an average body weight of 588 ± 34 g, were randomly assigned to four groups: a control group fed a standard diet, a group (T1) receiving the basal diet supplemented with 1.5% coriander seed powder, a group (T2) receiving the basal diet with oral LAS at 1 × 109 CFU/kg, and a group (T3) receiving both coriander seed powder and LAS. The study measured body weight, daily weight gain, feed conversion ratio, mortality rate, blood metabolites, nutrient digestibility, and intestinal histomorphology. Results showed that rabbits fed with 1.5% coriander seed powder had significant improvements in body weight gain, feed conversion, and a reduction in mortality compared to the control. Both coriander seed powder and LAS improved blood metabolites, nutrient digestibility, and intestinal health. However, the combination of both additives did not provide additional benefits over the individual treatments. The findings suggest that either 1.5% coriander seed powder or LAS can enhance growth performance and health in rabbits under subtropical conditions. |
Comparison of different modeling approaches to estimate cardinal temperatures for germination of Persicaria lapathifolia, Polygonum aviculare and Solanum nigrumOriginal PaperDonato Loddo, Stefano Carlesi, Neboj¹a Nikoliæ, Roberta MasinPlant Protect.

Progress and prospects in understanding the effects of forest management practices on soil nitrogen cyclingReviewLili Liu, Chenyi Yu, Jiayi Yang, Zijun Zhang, Qingwei GuanJ. For. Sci., 2025, 71(10):469-481 | DOI: 10.17221/61/2025-JFS Soil nitrogen (N) cycling plays a pivotal role in forest ecosystem productivity and nutrient regulation. This review synthesises recent advances in understanding how forest management practices influence soil nitrogen cycling and highlights future research priorities for elucidating underlying mechanisms and optimising forest ecosystem functioning (Figure 1). Management interventions such as thinning, species composition adjustment, and understory vegetation control have been shown to affect N inputs and transformation pathways by modifying litter quality, microbial community structure, and N-cycling enzyme activities. However, current findings remain inconsistent, and mechanistic insights are still limited. Future research should focus on disentangling the multi-scale, multifactorial interactions through which forest management regulates soil N cycling. Integrative approaches that link molecular biology with ecosystem-level processes are needed to clarify the interplay among microbial dynamics, enzyme activity, root exudates, and soil physicochemical properties across spatial and temporal scales. In addition, research should explore how forest management affects community structure, litter inputs, soil aggregation, and subsurface biochemical processes to reveal the synergistic regulation of nitrogen cycling by biological, physical, and chemical drivers. Establishing long-term monitoring networks across a range of forest types and climatic regimes, combined with tools such as metagenomics, high-throughput sequencing, and stable isotope tracing, will enable the precise characterisation of key nitrogen-cycling genes and fluxes. In the context of global environmental change, it is also crucial to assess how forest management modulates the coupling of nitrogen, carbon, and water cycles and the resultant ecological feedbacks. |
Efficacy of a new ready-to-use PCV2 and Mycoplasma hyopneumoniae vaccine under field conditionsOriginal PaperP Trampus, A Csagola, T Szalai, N Palmai, A Toth, N Terenyi, Z Nagy, NA Szeplaki, G Somogyi, E Rausch, Z Penzes, R KrejciVet Med - Czech, 2025, 70(11):401-407 | DOI: 10.17221/25/2025-VETMED Coinfection of porcine circovirus type 2 (PCV2) with Mycoplasma hyopneumoniae (M. hyo) causes major worldwide economic losses within the swine industry. This study aimed to assess the safety and efficacy of a single dose of a bivalent vaccine containing PCV2d and M. hyo antigen (Cirbloc® M Hyo) under field conditions. Two studies were performed under the GCP (Good Clinical Practice) requirements on farrow-to-finish farms in Hungary and Cyprus. On both farms, the presence of both PCV2 and M. hyo infection was demonstrated. For both studies, safety parameters were observed and measured from inclusion at 21 (±3) days of age until 14 days after vaccination. Efficacy parameters were observed and measured from inclusion until slaughter. Administration of the vaccine was safe in both studies, as no general, immediate, or local reactions were observed. The efficacy of the vaccine was confirmed in both studies as the following parameters were significantly reduced in the vaccinated groups compared to the control groups: viraemia, faecal shedding, viral load in lungs and in all collected lymphoid tissues, M. hyo-specific lung lesions, and average daily body weight gain. These results collectively support the vaccine’s potential as an effective tool for disease control. |
Effects of microplastics on farmland soils and plants: a reviewReviewMinhua Zhang, Weiguan Li, Qingkui Li, Aneela Younas, Muhammad Shaaban, Yuyang Li, Jing Liu, Yanfang Wang, Zhanqiang Ma, Zhaoyong Shi, Hongtao Shen, Ling LiuPlant Soil Environ., 2025, 71(12):829-848 | DOI: 10.17221/180/2025-PSE Microplastics (MPs) are plastic particles smaller than 5 mm in size, which are widely present and have become one of the major pollutants in the natural environment, and are increasingly recognised as emerging pollutants in agricultural ecosystems. Due to their small size and high mobility, MPs can easily migrate into farmland soils and attach to plant surfaces, thereby altering the physical, chemical and microbial properties of the soil. These changes may affect seed germination, plant growth, and physiological and biochemical functions. This review systematically synthesises current research on the impact of MPs on agricultural soil, focusing on their effects on soil structure, chemical properties and microbial diversity. The positive and negative effects of MPs on plant seed germination, growth, and physiological and biochemical processes are critically analysed. Furthermore, the potential ecological risks of MPs to soil and plant health are discussed. Mitigation strategies and future research priorities are proposed to address MPs contamination in agricultural systems. This study aims to provide both theoretical insights and practical references to support the prevention and control of MPs pollution in farmland soils, thereby contributing to sustainable agricultural development and soil ecosystem resilience. |

Variation in wood density between mature sessile oak and English oak trees growing in different vegetation zonesOriginal PaperVladimír Gryc, Kyriaki Giagli, Sergei Mikhailov, Marko Stojanoviæ, Dimitrios Tsalagkas, Hanu¹ Vavrèík, Petr HoráèekJ. For. Sci., 2025, 71(12):614-623 | DOI: 10.17221/74/2025-JFS Wood density is a fundamental functional trait influencing ecological adaptation, hydraulic safety, and timber utilisation in temperate hardwoods. This study investigated variation in wood density (12% moisture) across mature stands of two economically and ecologically vital European oak species, sessile oak [Quercus petraea (Matt.) Liebl.] and English oak (Quercus robur L.), growing in their characteristic vegetation zones in the Czech Republic. We assessed wood density at two heights (at 1.3 m and at the crown base) across six trees per plot and examined its relationship with tree-ring width and height. Results demonstrated statistically significant interspecific differences, with Q. petraea consistently exhibiting higher wood density (721 kg·m−3) than Q. robur (662 kg·m−3) at 1.3 m. Q. petraea showed a statistically nonsignificant higher density of 710 kg·m−3 at the crown base and an overall average of 717 kg·m−3, while Q. robur had densities of 701 kg·m−3 and 669 kg·m−3, respectively. Radial density profiles revealed species-specific patterns, with Q. robur showing a more uniform density distribution than the pronounced pith-to-bark gradients observed in Q. petraea. Regression analysis indicated that tree-ring width explained only 12–13% of the variance in density, so other anatomical factors, such as latewood proportion and tree-ring structure (number and cell size), should be examined as anatomical drivers of wood-density variation. |
Critique on the dipteran pests of commercial flower crops: An obligate threat to the floral industryReviewBabu Babu Sreelatha Anand, Kanna Selvaraj Suganya, Chinnaiah Muthiah, Jacob Rajangam, Subramanian Rajesh, Ramayya Nalini, Angappan SuganthiPlant Protect. Sci., 2024, 60(4):328-353 | DOI: 10.17221/29/2024-PPS The floral industry grapples with challenges like changing climatic scenarios, differences in market trends, rising costs, and severe losses posed by insect pests. The management of dipteran pests encompassing diverse species, such as leaf miners, midges, flies, and mosquitoes, has emerged as an obligate adversary, inflicting substantial economic losses in the cut and loose flower industry. Through a comprehensive analysis of existing literature, this paper delves into the diverse array of dipteran species of leaf miners and midges, their life cycles, distribution, host range, damaging symptoms, insecticide resistance, and the management strategies practised to date. Furthermore, this critique underscores the urgent need for innovative approaches and integrated pest management techniques to mitigate the escalating menace of dipteran pests. By elucidating the multifaceted challenges and proposing strategic interventions, this critique aims to foster dialogue and inspire concerted action among researchers, stakeholders, and scholars to safeguard the sustainability and profitability of the floral industry. |
Effect of surface-applied compost on soil propertiesOriginal PaperMarkéta Miháliková, Kamila Bá»ková, Petr Dvoøák, Recep Serdar Kara, Cansu Almaz, Martin Král, Barbora Badalíková, Kvìtu¹e Hejátková, Vladimír Ma¹án, PatriSoil & Water Res., 2025, 20(2):71-83 | DOI: 10.17221/148/2024-SWR The positive influence of surface compost application without incorporation on soil physical properties is known but remains underexplored. This study evaluated the effects of surface-applied stable and mature compost on basic soil physical and chemical properties, including saturated hydraulic conductivity, aggregate stability, and penetration resistance. Conducted as a semi-operational field experiment in two Czech agricultural sites (A: Blatnice at Jaromìøice and B: Jevíèko; Cambisols with loam and silty clay loam textures, respectively), the plots were treated with compost (SCA) at rates of 4 × 30 t/ha (A) and 1 × 200 t/ha (B) or left untreated as controls (CON). The crops were wheat (A), maize (A, B) and intercrops. Surface compost application began in 2022, and soil sampling and field measurements were conducted during the 2023 and 2024 growing seasons. Results showed significant positive changes (P < 0.05 or lower) in SCA plots compared to CON. Soil organic matter content increased by 27.8% at locality A and by 58.1% at locality B, while saturated water content increased by 5.3% (A) and 11.0% (B) in the latter season. Similarly, pH and electrical conductivity showed increases. Water-stable aggregate ratios increased by 6% to 30% at both localities. Dry bulk density decreased by 10.5% (A) and 15.7% (B). Improvements in saturated hydraulic conductivity (by 28.6%) and penetration resistance were observed only at locality B. These findings show the potential of surface-applied stable and mature compost to enhance soil properties effectively. |
New version of PUGIS - Soil information system of the Czech RepublicOriginal PaperAdéla Marie Marhoul, Tomá¹ Herza, Josef Kozák, Jaroslava Jankù, Jan Jehlièka, Lubo¹ Borùvka, Karel Nìmeèek, Miroslav Jetmar, Petr PolákSoil & Water Res., 2025, 20(1):1-15 | DOI: 10.17221/138/2024-SWR The creation of the database system represents a complex task which is difficult to coordinate. In this work, a method of the logic framework was used for the coordination of each particular step to one integral part. In the Czech Republic, most of the information about soil was gathered within a systematic soil survey (KPP) in the period 1961–1970. Information about genetic and agronomic characteristics of agricultural soils was gathered for the whole Czech Republic. The other part of the data is coming from the databases of forest soils. This contribution is a continuation of the previous research. We are aware of the fact that in the Czech Republic exist also other soil information systems. In this work we also tried to show the practical exploitation of the large soil database. We applied many approaches to assess bulk density of the soil. It was calculated for the main soil groups and it could be applied on every soil profile in PUGIS system. We also showed different possibilities of mapping soil organic concentration or amount in soils. |
Analysis of selected functional parameters of saw chainsOriginal PaperPavel Nevrkla, Lubo¹ Stanìk, Jindøich NerudaJ. For. Sci., 2025, 71(2):72-85 | DOI: 10.17221/64/2024-JFS Results obtained from the research study focused on the functional parameters of five saw chains tested on a test bench equipped with an electrically driven chain saw brought a number of findings. One of the most important of them is the significant difference between the cutting rates of round and square chains. The cutting rate of square chains R = 27.9 cm2·s–1 is about 12% higher than the cutting rate of round chains. The influence of the chain construction on the chain cutting rate was conclusively demonstrated – the cutting rate of chains with a square profile is higher than the cutting rate of round-profile chains. It was further found out that although the specific energy Em = 77.8 Ws·cm–2 is by ca. 7% lower in the square chain than in the round chain, Student's t-test did not reveal any statistically significant difference in the data on the specific energy consumption of round and square chains, i.e. the influence of the chain design on the specific energy consumption of the chain at cutting was not clearly demonstrated. Other findings, for example, showed that working with a loose saw chain on the guide bar impairs parameters of the chain operation or that energy demands of cutting with the saw chain are directly proportional to wood density (hardness) and increase with the decreasing wood moisture. Yet another finding was learning the energy flow structure, which indicated that 46% of total power input is consumed by the electric motor alone for its operation while only about 7% goes for driving the chain movement along the bar (without cutting) and power input required for cutting is approximately 46%. |
Application predictive modelling of Penicillium roqueforti germination in environmental conditions in cakeOriginal PaperHassan Nakhchian, Farideh Tabatabaee Yazdi, Seyed Ali Mortazavi, Mohebat MohebiCzech J. Food Sci., 2025, 43(1):8-16 | DOI: 10.17221/84/2024-CJFS This study aimed to predict the germination of Penicillium roqueforti as one of the most important moulds in cake in certain environmental conditions that lead to cake spoilage. The germination rate of P. roqueforti was evaluated by culturing in the Yeast Extract Glucose Chloramphenicol Agar medium with different pH, water activity (aw), and inoculum size at three levels of temperature (15, 25, 30 °C) during 60 days by the factorial experiment. The results of analysis of variance (ANOVA) proved that environmental conditions affect germination significantly (P < 0.05). Predictive modelling illustrated that the temperature did not affect germination significantly, while no germination was seen at aw = 0.65. The minimum lag phase of germination was observed at aw = 0.9, pH = 6.5, and inoculum size of 1 000 spores per mL. The logistic model was found to be more precise for fitting the data of P. roqueforti in cakes. |

Effectiveness of glycerin-oxalic acid strips and essential oils in controlling Varroa destructor in honeybeeOriginal PaperPR Hristov, IS Hristakov, AZ Atanasov, PA ZhelyazkovVet Med - Czech, 2025, 70(3):101-109 | DOI: 10.17221/94/2024-VETMED The decline in the bee colony strength due to high levels of Varroa destructor infestations necessitates the development of new control methods. This study evaluates the effectiveness of glycerin-oxalic acid strips and essential oils in managing Varroa destructor. The experiment was conducted in 2022 at the experimental apiary in Debelec, part of the Institute of Animal Husbandry in Kostinbrod. Six experimental groups, each treated with a different preparation, were compared to a control group of untreated colonies. Treatments included Beevital Hiveclean (20 ml per colony), Varro Red (2 ml per frame), ammonium nitrate strips (1.3 mm), glycerin-oxalic acid strips (1.3 mm), and glycerin-oxalic acid strips of paper-cellulose (2.3 mm) or cellulose-cotton (2.3 mm). The control group remained untreated. The glycerin-oxalic acid strips made of cellulose and cotton (2.3 mm) showed the highest efficacy, reducing the mite infestation by 17.79% compared to the control. The glycerin-oxalic acid strips of paper-cellulose (2.3 mm) were also effective, achieving a 17.05% reduction in mite levels. These results provide valuable insights for beekeepers seeking alternative and sustainable methods for controlling Varroa destructor infestations. |
Comparative evaluation of fungicide effectiveness in controlling Coffee leaf rust in Hawai‘iOriginal PaperZhening Zhang, Julia A. Coughlin, James K.F. Kam, Zhiqiang ChengPlant Protect. Sci., 2025, 61(2):162-171 | DOI: 10.17221/92/2024-PPS Coffee leaf rust (CLR), Hemileia vastatrix, is a disease that has severely impacted the major coffee growing areas of the world. The discovery of CLR in Hawaii in October 2020 was devastating news to local growers, as it quickly spread to all coffee-growing areas, threatening the second-highest-valued crop in the State. Although the fungicide Priaxor Xemium had been approved as a Section 18 emergency exemption, there was still an urgent need for true systemic fungicides to provide sustained control of the disease. The study's overall objective was to test the efficacy of various systemic fungicides against CLR in field conditions. During the coffee growing season for two years, various fungicides were tested on two farms in the Kona district of Hawaii. Treated trees showed an 84% reduction in CLR incidence compared to untreated trees in Year 1 and a 79% reduction in Year 2 by the end of the study. Treated trees also had 12% and 38% more total leaves per branch than untreated trees in Years 1 and 2, respectively. All fungicide treatments provided excellent or good control of CLR compared to the untreated control under the climate of Hawaii. |
Effect of application of microbiological preparation and different nitrogen fertilisation on wheat yield elementsOriginal PaperSuzana Kristek, Jurica Joviæ, Josipa Janto¹, Marina Martinoviæ, Zdenko LonèariæPlant Soil Environ., 2025, 71(7):500-508 | DOI: 10.17221/18/2025-PSE Two-year experiments were conducted on two different soil types during 2021/22 and 2022/23 to study the impact of microbiological preparations, Mycor-FAZOS and Vitality-FAZOS, on the yield and quality elements of winter wheat cultivar Maja (Agrigenetics). The experiment was set up in a split-block design with four repetitions across two soil types, with 12 different variants on each soil type. The base plot area was 40 m2, and the effective plot area was 27 m2. The research factors included: A (soil type): A1 – gley soil; A2 – eutric cambisol; B (disease control): B1 – control; B2 – chemical pesticides; B3 – biopreparates (seed treatment + foliar treatment) and C (nitrogen fertilisation): C1 – based on soil analysis; C2 – 70% of recommended application. Variables included grain yield (t/ha), grain protein content (%), hectoliter weight (kg), and plant height (cm). The highest average grain yield was achieved with variant B3C2, with a 12.50% increase compared to variant B2C1. Differences between these variants included 6.0% for protein content, 5.97% for hectoliter weight, and 7.93% for plant height. It was observed that Mycor-FAZOS seed treatment promoted root development, resulting in healthier, taller, more robust plants with a more uniform growth and darker colour than untreated seed variants (indicating increased photosynthesis index). The protection achieved with Vitality-FAZOS biopreparations (fungicidal microorganisms synthesising growth hormones) ensured healthier wheat plants, leading to higher seed yield and better quality parameters. |
Psychological perspectives on smallholder farmers' choice of climate change adaptation strategies and productivity nexus in Southwest, NigeriaOriginal PaperAdetomiwa Kolapo, Akeem Abiade Tijani, Seyi Olalekan Olawuyi, Adeyera James Kolapo, Temitope Oluwaseun Ojo, Nolwazi Zanele Khumalo, Khalid. Mohamed Elhindi, Hazem KassemAgric. Econ. - Czech, 2025, 71(4):185-202 | DOI: 10.17221/87/2024-AGRICECON In recent pasts, high priority has been placed on encouraging the implementation of various climate change adaptation techniques to adapt to the disastrous effects of climate change. Like in other countries affected by climate change, Nigerian farmers were also encouraged by governmental and non-governmental organisations to implement techniques for adapting to climate change impact. In this study, we use a psychological approach to investigate how a mix of socioeconomic and psycho-cognitive factors affect smallholder farmers' decisions about various climate change adaptation strategies and the consequent impact of the adoption of adaptation strategies on crop yield. Following the theory of planned behaviour (TPB), the adoption decision of farmers was modelled using the partial least squares structural equation modelling (PLS-SEM) and the ordered probit model. The impact of adopting adaptation strategies on productivity was evaluated using multinomial endogenous switching regression (MESR). The MESR helps to address endogeneity issues that might arise as a result of inconsistencies in the behavioural responses of the farmers. Our result indicates that psycho-cognitive factors like intentions and personal norms significantly predicted the number of climate change adaptation strategies the farmers ultimately embraced and implemented on their farms. We also found that the smallholder farmers' yield and income were most significantly impacted by the adoption of land restoration as a climate change adaptation strategy. The findings will assist in the design of more effective policy instruments to remove adoption hurdles as well as crafting tailored extension services that resonate with the realities of the farmer and thus help foster behavioural change. |

Life cycle assessment of bioenergy production from short-rotation coppice plantation in HungaryOriginal PaperBudi Mulyana, Andrea Vityi, András PolgárJ. For. Sci., 2025, 71(5):237-249 | DOI: 10.17221/10/2025-JFS A short-rotation coppice (SRC) system for bioenergy production is vital to supporting climate change mitigation by absorbing CO2 from the atmosphere and storing carbon as biomass. However, SRC's operation also released some greenhouse gas emissions, affecting the environment. This study aims to assess the potential environmental impacts through the life cycle assessment method in bioenergy production from the SRC system. Data was collected through a literature review and database, and the impact categories were then analysed using Sphera LCA for Experts Education License software (Version 9.2.1.68, 2020). In managing plantations for bioenergy production, plants during one rotation (15 years) will be harvested every 3 years (harvesting cycle). Then, there will be five harvesting cycles during a single rotation. The result showed that the first cycle had the highest environmental impacts because the inputs (fuel, lubricant, electricity, fertiliser, and pesticides) in this cycle were higher than others. The highest contribution comes from the first and end cycles as 3 200 and 2 700 kg CO2 eq, respectively. Meanwhile, cycles 2, 3, and 4 contribute to the carbon footprint as 2 500 kg CO2 eq for each cycle. Based on input, fuel consumption has resulted in higher environmental impacts than lubricants, fertilisers, and electricity consumption. In conclusion, energy consumption (fuel, lubricant, and electricity) and agrochemicals (fertilisers and pesticides) have released emissions and affected the environment. In the future, fuel and agrochemical consumption should be reduced to minimise the negative environmental impacts in the short-rotation coppice system. |
Application of cold atmospheric microwave plasma on four domestic pigeons (Columba livia domestica) with open woundsCase ReportK Zelaya, JH Han, J Kim, SY Ahn, YD Suh, DN Lee, SC YeonVet Med - Czech, 2025, 70(6):218-225 | DOI: 10.17221/13/2025-VETMED This paper reports the feasibility of cold atmospheric microwave plasma (CAMP) therapy for birds with open wounds. Four domestic pigeons (Columba livia domestica) with open wounds of varying severity were treated with CAMP as an adjunct to conventional therapy. Wound healing was assessed using a modified scoring system during each treatment session, and the extent of healing was calculated as a percentage. The results revealed variability in wound improvement across cases, influenced by the initial severity of the wounds. In some cases, the outcomes were limited due to underlying conditions that overrode the recovery process, suggesting that the extent of healing may depend more on the initial wound condition than the treatment itself. Nevertheless, other cases showed positive results in healing and recovery under CAMP therapy, highlighting its potential benefits. No adverse reactions or complications were encountered, supporting its safety for avian wound management. These findings suggest that although CAMP can potentially promote wound healing, further studies will be needed to establish standardised treatment protocols. |
Effect of pasteurisation and high-pressure processing on selected bioactive components in human milk – An experimental studyOriginal PaperMiroslava Jandová, Michaela Fi¹erová, Pavla Paterová, Pavel Mìøièka, Jan Malý, Marián Kacerovský, Eli¹ka Kovaøíková, Jan Strohalm, Kateøina Demnerová, Jana Kadavá (email: jana.kadava@vsCzech J. Food Sci., 2025, 43(3):170-178 | DOI: 10.17221/45/2025-CJFS High-pressure processing (HPP) represents a promising alternative to conventional Holder pasteurisation (HoP) used by human milk banks worldwide. The objective of this study was to identify whether the HPP would achieve the same or better retention of the content of selected analytes than the HoP. Samples collected from 15 breast milk donors were processed in four ways: i) no treatment; ii) HoP; iii) HPP in cycles (350 MPa, 4 cycles); iv) continuous HPP (350 MPa, 20 min). The content of secretory immunoglobulin A (sIgA), lactoferrin and lysozyme was determined using commercially available ELISA kits, and the lipase activity was assessed using an A-lipase activity assay kit. Data were compared statistically using paired t-tests. HoP significantly reduced the content of lysozyme and lactoferrin as well as lipase activity (P < 0.001). Cycled HPP significantly decreased lipase activity (P = 0.002), while continuous HPP led to a significant decrease in lysozyme content (P = 0.001) and lipase activity (P = 0.014). Cycled HPP showed high retention of pretreatment levels of lysozyme – median 99 (88; 99%), lactoferrin – 84 (66; 105%), and sIgA content – 83 (28; 117%). Among the studied treatment regimens, the best preservation of initial levels of bioactive components was achieved using HPP at 350 MPa in cycles. |

Forest ecosystem restoration in the Ore Mountains: A review of silvicultural measures addressing environmental degradationReviewVeronika Hammerová, Stanislav Vacek, Zdenìk Vacek, Jakub Èerný, Jan Cukor, Josef Gallo, Michal KubìnkaJ. For. Sci., 2025, 71(7):323-335 | DOI: 10.17221/34/2025-JFS The forest dynamics of the Ore Mountains (Kru¹né hory), Czech Republic, reveal a historical decline of natural mixed forests, especially those dominated by the Hercynian mixture and European beech (Fagus sylvatica L.), due to the expansion of metallurgy and glassmaking in the 15th century. This led to large-scale reforestation with Norway spruce [Picea abies (L.) Karst.], resulting in single-layered monocultures. Although these monocultures provided valuable timber, they proved highly susceptible to both biotic and abiotic stressors. Throughout the 20th century, the stability of these forests further deteriorated due to air pollution (notably SO2 emissions), the unsuitable selection of substitute species, and the proliferation of pathogens. The cumulative impact of these disturbances caused soil acidification, degradation, and weed encroachment, severely limiting the regenerative capacity of forest ecosystems in this region. This article presents model examples of species composition shifts, spatial structure changes, and evolving management practices in the Ore Mountains. It discusses strategies for establishing diverse and resilient stands that align with long-term forest planning goals. These approaches aim to maintain both productive and ecological functions of forests under changing environmental conditions while minimising restoration costs. Importantly, forest management and conversion strategies must also account for economic optimisation, ensuring that ecological goals are met in a financially viable manner. The strategies and case studies presented here offer promising, albeit preliminary, directions for future forest management. Their broader application will require further refinement and long-term experimental validation to ensure sustainability in both ecological and economic terms. |
Haemotropic Mycoplasma species in cat blood samples by PCROriginal PaperO Gulaydin, M Yesilyurt, G Akgul, O Erdeger, K EercanVet Med - Czech, 2025, 70(8):294-301 | DOI: 10.17221/7/2025-VETMED Haemotropic mycoplasmas can cause severe anaemia in pets and also have zoonotic potential. The determination of these microorganisms from clinical samples is of critical importance. In this study, the presence of Mycoplasma haemofelis (Mhf), Candidatus Mycoplasma haemominutum (CMhm), and Candidatus Mycoplasma turicensis (CMt) in blood samples collected from 62 cats was investigated. Haemotropic mycoplasmas were identified by PCR amplifying the 16S rRNA gene, and sequence analysis was applied for confirmation and differentiation of the species. Six (9.67%) blood samples were positive for haemotropic mycoplasmas. CMhm and CMt were identified in five (8.06%) samples and one (1.61%) sample, respectively. Mhf was not detected in the samples. Additionally, a co-infection was not observed in any of the cats. It was found that the PCR positivity was not related to the sex or clinical status of the cats. To our knowledge, this is the first report investigating haemotropic mycoplasmas in blood samples from cats in Siirt Province of Türkiye. It is suggested that the data obtained from this study will contribute to clinicians working on pet animal health in this province. |
