How do green finance, digital technology, trade openness, and climate change interact to shape food production in sub-Saharan Africa?Original PaperAbdul Salami Bah, Yongqiang Wang, Yuchun Zhu, Saffa Mohamed Massaquoi, Nomore NkhomaAgric. Econ. - Czech, 2026, 72(3):135-155 | DOI: 10.17221/227/2025-AGRICECON The promotion of sustainable food productivity through innovative technologies remains a central priority in economic development, attracting increasing attention from scholars, policymakers, and industry stakeholders. With the continuing rise in global food demand, resource-efficient solutions are essential to ensuring long-term agricultural growth and stability in food production. This study examines the impact of green finance, agricultural innovation, digital technology, trade openness, and climate change on food production in sub-Saharan Africa (SSA). Using the method of moments quantile regression (MMQR) and the generalised method of moments (GMM), it analyses a balanced panel dataset covering 46 SSA countries from 2001 to 2023. The findings highlight the positive influence of green finance, agricultural innovation, and digital technology in enhancing food production, particularly in lower production sectors, suggesting important bidirectional policy implications. Trade openness is found to promote agricultural growth but exhibits diminishing effects at higher levels of productivity, indicating the relevance of a unidirectional policy focus. In contrast, climate change has a negative effect on food production. The study also identifies key mediation pathways, including green finance stimulating research and development, digital technology improving agricultural credit and farmers' education, and trade openness attracting foreign direct investment. These results emphasise the importance of integrated policy frameworks that combine financial support, technological advancement, and trade openness to promote sustainable agricultural growth and strengthen food security across SSA. |
Soil pore structure and its research methods: A reviewReviewNannan Wang, Tibin ZhangSoil & Water Res., 2024, 19(1):1-24 | DOI: 10.17221/64/2023-SWR Soil pore is an important part of soil structure. According to the causes of formation, soil pores can be divided into biological pores formed by animal movement and plant root development and non-biological pores formed by dry-wet and freeze-thaw alternation or artificial tillage. The soil pore structure affects the migration of water, gas, nutrients and so on in the soil, especially the macropores can also produce water or solute preferential migration. Studying soil pores is of great significance for predicting soil hydraulic properties, reducing groundwater pollution and soil nutrient loss. Based on previous studies on soil pore structure, this paper systematically summarized the role of soil pores, influencing factors and the advantages and disadvantages of various research methods. This paper not only introduces traditional methods (including direct and indirect methods), but also summarizes the new research on soil pores combined with computed tomography (CT) technology and other science and technology in recent years. Finally, the prospect and development trend of soil pore research in the future were predicted, so as to provide reference for further research on soil pore structure. |

Administrative system of afforestation in the Czech Republic: A long journey to a new forestReviewMartin Baláš, Josef Gallo, Marcin Czacharowski, Michal Pástor, Jaroslav Jankovič, Igor Štefančík, Ivan Kuneš, Hubert HasenauerJ. For. Sci., 2024, 70(2):41-63 | DOI: 10.17221/75/2023-JFS This review uses a case study based on an executed afforestation project to comprehensively describe the administrative procedure regarding afforestation of agricultural land in the Czech Republic, Central Europe. We consider the official proceedings for obtaining a permit to land-use change (i.e. changing the nature of land use and the mode of land use in the real estate cadastre) as a very complex and protracted procedure, which can substantially reduce the motivation of people to establish new forests. Therefore, we propose a simplification of the administration process of land-use change. The main idea is to make the procedure as simple as possible in those areas where afforestation is desirable, especially from the environmental point of view. It assumes the possibility of quick, precise and, if possible, automatic distinction whether the afforestation is suitable or not. The situation in the Czech Republic is compared with the surrounding Central-European countries: Poland and Slovakia. In these countries, the official procedure connected with afforestation seems to be rather less complicated. |

Exploring the role of endophytic fungi in the amelioration of drought stress in plantsReviewAlulutho Nombamba, Ayomide Emmanuel Fadiji, Olubukola Oluranti BabalolaPlant Protect. Sci., 2024, 60(3):213-228 | DOI: 10.17221/25/2023-PPS Drought is one of the environmental stresses that threaten food availability. It results in decreased crop yields and developments and diminishes overall plant health. Chemical solutions for alleviating drought stress may be harmful to the environment. Using an alternative, microorganisms help counter the effects of drought stress. Endophytes have a mutualistic relationship with the host as they provide protection and get nutrients. Fungal endophytes assist plants in countering the damaging results of drought stress by producing phytohormones and growth-promoting compounds that promote root and shoot growth and enhance crop productivity. Inoculating maize plants with endophytic fungi like Fusarium oxysporum and Penicillium sp. have a higher chance of surviving drought stress. These organisms can increase root length, allowing moisture to reach deeper into the soil. This review explores endophytic fungi's roles in alleviating drought stress’s consequences on plants. More investigations should be carried out on the favourable effects of fungal endophytes in the mitigation of drought stress through pot and field inoculation. |
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. |
Age-related phenological and anatomical response of European beech (Fagus sylvatica L.) under severe summer drought conditionsOriginal PaperDimitrios Tsalagkas, Hanuš Vavrčík, Vladimír Gryc, Kyriaki GiagliJ. For. Sci., 2024, 70(9):458-475 | DOI: 10.17221/16/2024-JFS The year 2018 was distinguished by a warm summer with extended periods of low or no precipitation. In this context, we investigated the intra-annual dynamics of xylem differentiation phases and quantitative vessel anatomy to analyse the age effect on the xylem formation response of younger (50 years) and older (135 years) mature European beech trees under summer drought conditions. The xylem formation dynamics of young and old trees were performed on microcores collected at weekly intervals in the Rájec-Němčice ecological station in the South Moravia region (Czech Republic). The onset of xylem formation was found identical in both age trees, and most of the trees ceased their enlargement by the end of July, which is attributed to the harsh environmental conditions of this month. Young trees were characterised by a 10-day extended enlargement period and a higher growth rate, resulting in more vessels and a wider tree-ring width. No significant linkage was found between intra-annual environmental conditions of the 2018 year or age effect and the vessel anatomy traits. |
Magnesium deficiency or excess hinders tomato growth, potassium and calcium uptakeOriginal PaperHuixia Li, Fang Liu, Xueke Zhang, Jingbo Gao, Ping ChenPlant Soil Environ., 2024, 70(11):719-730 | DOI: 10.17221/473/2023-PSE Despite accumulating evidence for the adverse effects of magnesium (Mg) deficiency or excess on grain crops, how Mg imbalance affects plant growth and potassium (K) and calcium (Ca) nutrition in vegetable crops is still unclear. The aim of this study was to ascertain the response of plant growth, nutrient uptake and Mg-K-Ca interactions in tomato (Solanum lycopersicum L.) to various levels of Mg supply. The growth parameters and nutrient contents of hydroponic plants were measured under the Mg levels of 0, 0.5, 1.0, 1.5 and 3.0 mmol/L Mg2+ from seedling to fruit ripening stage. Results showed that both Mg deficiency (0 mmol/L Mg2+) and excess (3.0 mmol/L Mg2+) negatively affected shoot and root growth, leading to a noticeable decrease in total plant biomass across different stages (41.2–52.8% and 17.7–38.3%, respectively). Mg imbalance additionally altered leaf morphology and disrupted chloroplast structure. As a consequence of increased Mg levels, the Mg contents in various plant organs increased, whereas the Ca contents decreased substantially. The trend of K contents under different Mg levels was dependent on the plant growth stage. Although Mg levels did not prominently affect plant K contents during the early growth stage, they were significantly negatively correlated in the leaves and positively correlated in the fruit during the late growth stage. When translocated from roots to aboveground organs, Mg and Ca were mainly distributed in the leaves, with K preferentially distributed in the fruit. The findings of this study underscore that the symptoms of Mg imbalance generally develop from middle leaves in vegetable crops, exemplified by tomato, which is different from the pattern in common grain crops. Vegetable production necessitates nutrient supply for the middle and upper parts of Mg-deficient plants, and attention should be paid to the nutritional imbalance of Ca and K in plants under excessive Mg supply. |
Parameters of labile organic carbon as the indicators of the stability of soil organic matter under different land useOriginal PaperErika Balontayová, Juraj Hreško, Viera Petlušová, Peter Petluš, Bożena Dębska, Tomáš LošákSoil & Water Res., 2025, 20(1):52-68 | DOI: 10.17221/119/2024-SWR The labile fractions of organic carbon (OC), which are a reflection of the properties of soil and its use, appear to be suitable parameters for their use as indicators. The aim of this study was to determine the reliable and relatively simple indicators for detecting the chemical and physical stabilizations of OC, which would respond sensitively to land use. The study includes forest ecosystem (FE) and agroecosystem (AE) with different tillage intensities (reduced tillage, RT and conventional tillage, CT) on real farms. Parameters of the labile C and N were tested. For a depth of < 0.1 m in the FE, the hot water extractable organic carbon (HWEOC) for chemical stabilization and labile nitrogen (NL) for physical stabilization appear as the most suitable indicators. Higher values of HWEOC indicate the OC stabilization by decreasing decomposition, pH or by increasing carbonates, recalcitrant fractions, and higher values of NL by OC incorporation into the silt fraction and larger macro-aggregates. In the AE with RT, these are the HWEOC for chemical stabilization and carbon pool index (CPI) or index of carbon lability (LIC) for physical stabilization. Higher values of CPI and LIC indicate the stabilization by the formation of size-optimal dry-sieved (DSA; 1–3 mm) and wet-sieved (WSA; 1–2 mm) soil aggregates. In the AE with CT, it was the NL. Its higher values point to the stabilization through the carbonates, alkaline cations, size-fraction of > 0.01 mm and the formation of DSA (1–3 mm). For a depth of < 0.3 m in the AE, these are the CL (for RT), higher value of which points to the stabilization by clay and alkaline cations, and HWEOC (for CT), higher value of which indicates the stabilization in the conditions of the soil acidification. |

Control of odour and gaseous emissions from livestock buildings: Recent research and developmentsReviewRoger Jay Lamadrid De VelaRes. Agr. Eng., 2024, 70(4):181-197 | DOI: 10.17221/55/2024-RAE One major challenge in the continuous growth of the livestock industry is the increased emission of odorous gases, which is not just a nuisance but also a cause of serious health and environmental concerns. Several strategies which aim to: (i) reduce the formation of odorous gases; (ii) enhance dispersion of odour; (iii) capture odour and gases to prevent escape to the environment; and (iv) reduce odour and gaseous concentrations, are developed. These are achieved with the use or employment of one or more of: (i) diet manipulation techniques; (ii) additives and adsorbents; (iii) covers; (iv) shelterbelts or windbreaks; (v) ventilation systems; (vi) biofilters; and (vii) air scrubber. The advantages and limitations of each of these strategies are discussed in this review in order to guide the choice of which strategy to use in a specific livestock application. Moreover, this review also discusses potential researchable areas in the field of odour control in livestock facilities. |
Biochar innovations for sustainable agriculture: Acidification and zinc enrichment strategies to improve calcareous soil fertility and wheat yieldOriginal PaperSalih Demirkaya*, Coskun GülserSoil & Water Res., 2025, 20(2):105-118 | DOI: 10.17221/77/2024-SWR Calcareous soils, typically characterized by low fertility, low organic matter and nitrogen content, and often deficient in phosphorus, zinc, and iron, as well as having low microbial activity, require the development of sustainable soil conditioners to improve fertility. To address these shortcomings and promote sustainable agriculture, biochar, especially with acidic character, may offer a promising solution. This study investigates the effects of modified biochar by H2SO4 and ZnSO4 on soil properties and wheat yield under field conditions. For this purpose, biochar (B), acidified biochar (AB), Zn enriched biochar (BZn), and acidified-Zn enriched biochar (ABZn) were applied to the field at two different doses (0.5 and 1.0%) together with the control treatment (Ck) without biochar application. AB1.0% was determined as the most effective treatment in decreasing soil pH (0.15 units), while B1.0% was determined as the most effective treatment in increasing organic carbon and cation exchange capacity, 13% and 32%, respectively. The effect of the treatments varied for specific nutrients. The highest antioxidant enzyme activities were found in acidified biochars where the lowest yields were obtained. Compared to the Ck, the highest catalase (CAT) (32%) was determined in ABZn1.0%, ascorbate peroxidase (APX) (56%) and glutathione peroxidase (GPX) (36%) were determined in ABZn0.5%, and superoxide dismutase (SOD) (28%) was determined in AB0.5%. The highest proline (PRO), with the least decrease in yield, was found in the AB1.0% application, which is 205% more than Ck. B and BZn treatments all increased the grain yield, and the highest increase was 20% in B1.0% when compared to the Ck. |
Effects of dried fig flour incorporation as a natural additive on nutritional composition and sensory assessment of biscuitOriginal PaperBerrighi NabilaCzech J. Food Sci., 2025, 43(1):37-47 | DOI: 10.17221/187/2024-CJFS The aim of this work is to characterize the physicochemical and techno-functional properties of dried fig flour to investigate its effect on the qualities of biscuits on the one hand and to encourage the use of this aromatic and medicinal plant in the agri-food industry. During this study, figs and wheat grains were dried and subsequently ground to obtain a flour that was used in various proportions of 0%, 50% and 100%, respectively in the manufacture of the biscuit. The flours were examined for proximate composition, polyphenol and tannin levels, along with functional properties. Flour derived from dried figs showed higher levels of crude ash, sugar, fiber, polyphenol and tannin, as well as greater water absorption capacity and density. The results indicated that incorporating dried and rehydrated fruits increased the total antioxidant activity of the biscuits compared to the control sample. The detailed organoleptic analysis, conducted through a tasting test revealed that all tasters found the dry biscuits acceptable. Biscuits formulated with 50% fig powder exhibited improved sensory attributes, including attractive colour, a crispy texture, and a more pronounced flavour. The use of this aromatic and medicinal plant in the food industry, particularly in biscuit production, holds significant potential. It enhances the nutritional value while imparting a sweet taste, distinctive flavour and natural colour. Additionally, its use contributes to improving the functional attributes of biscuit products, offering a sustainable approach to valorizing dried fig flour. |
The use of silver nanoparticles in pigs – An invited reviewReviewN Hodkovicova, M Machacek, J Cahova, J Consolacion, A Siwicki, Z Pejsak, M SvobodaVet Med - Czech, 2025, 70(3):77-92 | DOI: 10.17221/101/2024-VETMED Silver nanoparticles (AgNPs) have attracted significant interest in veterinary medicine due to their unique properties, including enhanced stability, greater antimicrobial efficacy, and reduced toxicity compared to traditional silver salts. Their applications span various areas of veterinary practice, such as dermatology, wound management, infection prevention, drug delivery, and disinfection. This review explores their use in pigs, highlighting their role as feed additives to prevent diarrhoea, as antibacterial agents in semen extenders, and veterinary dermatology. AgNPs possess broad-spectrum antibacterial activity against both Gram-positive and Gram-negative bacteria, positioning them as a promising alternative to antibiotics in addressing antibiotic resistance. Additionally, AgNPs have shown antiviral potential, though the exact mechanism of action remains unclear. The review examines the antibacterial and antiviral properties of AgNPs, their utility in facility sanitation, and their potential toxicity to pigs. While AgNPs offer significant benefits in veterinary applications, concerns about their toxicity persist. Efforts to reduce this toxicity, such as surface modifications or combining AgNPs with other substances, are under investigation. Further research is essential to fully understand the potential applications and safety of AgNPs in pig medicine. |
Does livestock manure recycling among acquaintance networks decouple crop and livestock production? Evidence from rural ChinaOriginal PaperYing Wang, Guanghui Jiang, Jisheng MinAgric. Econ. - Czech, 2025, 71(9):512-525 | DOI: 10.17221/219/2024-AGRICECON Livestock manure serves as a vital source of organic fertiliser, with efficient utilisation being crucial for sustainable agricultural development. However, with the development of specialised high-input agriculture, livestock manure recycling (LMR) is currently inefficient and leading to the imbalance between surplus manure and croplands. This study theoretically and empirically investigates whether LMR among acquaintance networks influence the crop–livestock integration (CLI) production. Based on survey data of swine farmers in rural China, the estimates indicate that LMR among acquaintance networks enhances the degree of CLI but may result in over-application of manure. Conversely, LMR with outside villagers or organisations is more likely to reduce the degree of CLI, possibly leading to under-application of manure. The motivation behind farmers' LMR plays a crucial role. Furthermore, the study indicates that formal institution can break the constraints of acquaintance networks on LMR and restructure the crop-livestock relationship beyond the household level. Our findings emphasise that LMR within rural China's acquaintance networks are in a transition phase, exhibiting both relational and market orientation characteristics. It is currently essential to maintain the balance between crop and livestock production, advance the development of LMR social services when designing LMR policies, and to leverage the complementary roles of informal and formal institutions. |
A review on crop improvement strategies and breeding methods in ornamental annualsReviewR Priyadharsini, K R Rajadurai, A Beaulah, M Madhan Mohan, K Venkatesan, S RajeshHort. Sci. (Prague), 2025, 52(1):15-32 | DOI: 10.17221/31/2024-HORTSCI The availability of a broad variety of cultivars in many ornamental species has increased recently, in particular for attractive annuals, which are valued commercially for their use as cut flowers, potted plants, loose flowers, and in landscape gardening. The breeding of ornamental plants in the current scenario is a challenging endeavour with constantly evolving new obstacles. Modern genomic technologies provide prospects for improved precision breeding and selection for characteristics that are more difficult to determine. Traditionally, ornamental breeding has been focused on increasing resistance to biotic or abiotic stress, novelty, yield, and quality. However, accomplishing these objectives necessitates tedious cross-breeding, and exact breeding methods have been noticed to be not applied constantly. Though the purposes of ornamental crop breeding may vary, the process generally does not differ from the breeding of other crops. Furthermore, vegetatively propagated ornamentals constitute most of the crops. The expanding interest in ornamental crops that are produced by modern crop breeding methods such as genome editing, chromosome manipulation, molecular marker-assisted breeding, mutation breeding, and exploiting somaclonal variations, particularly in relation to altering desirable plant features and producing new ornamental traits of the crops which is the main objective of crop improvement practices. Hence, it has become obligatory to evaluate the current state of any technology created following an in-depth study carried out by several research organisations. |
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. |
Physiological and biochemical responses to cold stress in sesame (Sesamum indicum L.) during the early growth stageOriginal PaperAhmed A. Abbas, Muez Berhe, Habtamu Kefale, Somaya A. Hussien, Rong Zhou, Ting Zhou, Huan Li, Yanxin Zhang, Zhongbo Guan, Chris O. Ojiewo, Jun You, Linhai WangPlant Soil Environ., 2025, 71(5):293-307 | DOI: 10.17221/79/2025-PSE Cold stress significantly impacts sesame during its early growth stages, with varying responses observed among different genotypes. Ten genotypes were evaluated for phenotypic response to various temperatures during germination. Cold stress at 10, 12, 14, and 16 °C inhibited germination, with zero germination at 10 °C. At 14 °C, genotypes showed significant germination variation, and it was selected as the threshold temperature for assessing cold tolerance in sesame. Four genotypes were grouped into two, and each group with extreme germination responses (high and low) were selected for further biochemical and physiological studies. Genotypes V5 and V7 exhibited higher cold tolerance, better germination percentage, and seedling parameters under low temperatures, while V8 and V9 showed significant reductions, indicating cold sensitivity. Biochemical analyses revealed that cold-tolerant genotypes had enhanced activities of antioxidant enzymes, including catalase, superoxide dismutase, and peroxidase, as well as higher proline accumulation compared to sensitive genotypes. These antioxidants played a crucial role in mitigating the oxidative stress induced by cold, as evidenced by lower levels of hydrogen peroxide and malondialdehyde in the tolerant genotypes. Cold-tolerant genotypes also accumulated higher soluble sugars and protein levels, contributing to osmotic regulation and membrane stability. The findings highlight the importance of enzymatic and non-enzymatic antioxidants in cold stress tolerance, suggesting these biochemical markers could be used to identify and develop cold-resistant sesame cultivars. The results offer valuable insights into the mechanisms underlying cold tolerance and provide a foundation for breeding efforts to improve sesame cold resistance. |
Changes in the concentration of CO2 in forest soils resulting from the traffic of logging machinesOriginal PaperLuboš Staněk, Jindřich Neruda, Radomír UlrichJ. For. Sci., 2025, 71(5):250-267 | DOI: 10.17221/6/2025-JFS The aim of the study was to find out whether and how the forest soil compaction resulting from the traffic of forest logging machines results in the increased soil air concentration of CO2, occurring over a longer period of time and in different seasons of the year. Changes in the soil air CO2 concentrations were monitored in two periods: in winter (cold period) and in summer (warm period). CO2 concentrations were measured in compacted and non-compacted soil using a certified measurement. In addition to the soil concentration of CO2, air temperature, soil temperature and soil moisture content were measured. The research was conducted in the Czech Republic. The obtained data was subjected to statistical analyses (Student's t-test; correlation analysis). The results of the study confirm the long-term influence of soil compaction by the traffic of forest machinery on the CO2 concentration in soil in both seasons (cold and warm). The concentration of CO2 in the air of compacted soil was always significantly higher in both periods than the CO2 concentration in the air of non-compacted soil (control). Thus, the negative influence of soil compaction was clearly demonstrated as a result of a single pass of forestry machines over the soil surface. |
Increased uptake and accumulation of phosphorus and other nutrients by legumes enhance their bioavailability for non-legume speciesOriginal PaperPeltier Aguiar, Margarida Arrobas, Manuel Ângelo RodriguesPlant Soil Environ., 2025, 71(6):409-425 | DOI: 10.17221/85/2025-PSE Legumes are promoted in agroecosystems for their ability to fix atmospheric nitrogen (N), thereby reducing or eliminating the need for N fertilisation while also contributing N-rich organic residues, which non-legume species can subsequently utilise. In phosphorus (P)-poor soils, certain legumes appear to access less available forms of P, converting them into organic P and facilitating its use by non-legume species. This study evaluated seven legume species/cultivars and one grass species (as a control) in a trial conducted in low-fertility soils under four different growing conditions (location × year). The objective was to investigate the role of legumes in P and other nutrient uptake and accumulation in plant tissues. Some lupins and broad beans accumulated up to 30 kg/ha of P in their biomass, even without accounting for P in the roots. Calcium (Ca) and magnesium (Mg) concentrations in plant tissues were also significantly higher in legumes than in grass. In addition to concentrating certain nutrients in their tissues, legumes produced substantially more biomass due to their access to atmospheric N, resulting in considerably higher nutrient accumulation. Ca and Mg in some legumes exceeded 100 and 40 kg/ha in aboveground biomass, respectively, whereas in grasses, they remained below 4 kg/ha. Thus, when legumes are cultivated as green manure, these nutrients are returned to the soil in organic form, which can subsequently become available to non-legume crops through the mineralisation process of the organic substrate. Therefore, cultivating legumes not only enhances N availability for other species but also improves the cycling of other essential nutrients. |
Mitigation of salinity stress effects on Vicia faba L. growth and productivity using proline and salicylic acid foliar applicationOriginal PaperHossam El-Beltagi, Mohamed El-Nady, Ahmed Mahmoud Ismail, Metwaly Mahfouz Salem MetwalyPlant Protect. Sci., 2025, 61(3):222-241 | DOI: 10.17221/127/2024-PPS High soil salinity causes a negative impact on plant growth and lowers crop yields. Thus, pot experiments were conducted to investigate the impact of foliar application of salicylic acid (SA) and proline (Pro), separately and combined, on enhancing salinity tolerance in broad beans. Salinity stress (4.69 ds/m and 6.25 ds/m) significantly reduced plant growth (plant height, leaf area, number of leaf/plant, plant dry weight), chlorophyll pigment content (chlorophyll a, b or total), relative water content, K/Na ratio, seed yield per plant, and N, P, K, and crude protein content in broad bean seeds. Foliar application of Pro and SA, either individually or in combination, enhanced plant growth parameters, chlorophyll pigment content, endogenous proline levels, phenol content, and the activities of antioxidant enzymes [antioxidant enzymes including catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD)]. Additionally, these treatments enhanced plant seed yield, N, P, K, and crude protein levels in the seeds. The combined foliar application of Pro and SA was more effective in mitigating salinity stress’s harmful effects than using either substance alone. These findings indicate that foliar application of SA and Pro, either individually or in combination, alleviated the adverse effects of salinity on broad beans, with the combined application proving to be the most effective. |
Influence of the drone brood homogenate on the gut integrity and cellular immunity: A pilot study on pigsOriginal PaperV Karaffova, D Mudronova, M Levkut, L Rajcakova, Erik Hudec, R Zitnan, P PatrasVet Med - Czech, 2026, 71(3):95-105 | DOI: 10.17221/98/2025-VETMED Drone brood homogenate (DBH), a nutrient-rich bee product, has received limited scientific attention despite its potential immunomodulatory and gut-protective properties. This study evaluated the effects of a dietary DBH supplementation on the intestinal barrier–related gene expression, phagocytic activity, and lymphocyte subpopulations in pigs. Eighteen weaned pigs were assigned to three groups (control, DBH100, DBH200) and fed DBH at 0, 100, or 200 mg/kg feed for 18 days. The gene expression of tight junction markers (occludin, claudin-1) and mucosal integrity–associated proteins (lumican, OLFM4) was assessed in the ileum by qRT-PCR. Phagocyte function and peripheral blood lymphocyte subpopulations were analysed by flow cytometry. DBH200 significantly upregulated the occludin, claudin-1, lumican, and OLFM4 expression, indicating enhanced intestinal barrier support. The phagocytes from both DBH-treated groups exhibited an increased engulfing capacity and an elevated oxidative burst index, though the percentage of active phagocytes was only weakly affected. The DBH supplementation did not alter the total T (CD3+) or B (CD21+) cells; however, both DBH groups showed a significantly increased CD4+ : CD8+ lymphocyte ratio, which is consistent with immune stimulation. These findings suggest that DBH may beneficially modulate the gut barrier integrity and selected components of innate and adaptive cellular immunity in pigs. |

However, there is very little research that has looked in depth into the factors that influence tourists' consumption of this product, especially in relation to epistemic benefits and responsible tourist behaviour. This study proposes a theoretical model based on the Theory of Planned Behaviour (TPB). We conducted a survey involving 619 travellers who regularly consume wine when visiting Tenerife (Canary Islands, Spain). The results show that epistemic benefit and responsible tourist behaviour have a positive relationship with attitudes toward local wine consumption, subjective norms, and perceived behavioural control. Furthermore, the relationships proposed by the TPB are confirmed, except for the relationship between subjective norms and behavioural intention. These findings provide new knowledge on local wine consumption by tourists which will help to develop strategies to encourage its consumption in tourist destinations. |
