Cahuiche (Vaccinium leucanthum Schltdl.): A berry with antioxidant, antihypertensive and antibacterial potentialOriginal Paper

Javier Castro-Rosas, Carlos Alberto Gómez-Aldapa, Edna Zaranne Martinez-Ramirez, Netzahualcoyol Calcáneo-Martíne, Reyna Nallely Falfán-Cortés

Czech J. Food Sci., 2025, 43(5):336-343 | DOI: 10.17221/218/2024-CJFS


The aim of this research was to quantify the bioactive compounds; antioxidant, antibacterial, and antihypertensive capability of different cahuiche (Vaccinium leucanthum Schltdl.) extracts in vitro. Aqueous, ethanolic, and methanolic extracts were obtained from cahuiche berries (Vaccinium leucanthum Schltdl.). Total phenols, flavonoids (quercetin and catechin), and anthocyanins contents were determined, and antioxidant activity was also determined using ABTS [2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic) acid] and DPPH (2,2-diphenyl-1-picrylhydrazyl), antibacterial activity, and antihypertensive potential, using angiotensin I-converting enzyme (ACE) inhibitor activity (%) in vitro. Methanolic extract showed the highest total phenols (1187.88 ± 87.48 mg gallic acid equivalents), catechin (372.17 ± 35.23 mg catechin equivalents), anthocyanins (578.89 ± 38.5 mg cyanidin-3-glucoside equivalents), ABTS (98.26 ± 0.00%) and DPPH (44.06 ± 3.95%) antioxidant activity, and ACE inhibitor activity of 80.20 ± 2.46%. All extracts presented antibacterial activity against Staphylococcus aureus (ATCC 25923) and Listeria monocytogenes (ATCC 19115) with inhibitor zones of > 11 and 13 mm, respectively. Cahuiche berries are potentially an ideal food or functional ingredient due to their biological activities as natural antihypertensive and antibacterial agent, and high bioactive compound contents.

Climate change and topographic variations affect infestation by Xyleutes ceramica (Walker, 1865) (Lepidoptera: Cossidae) in teak plantations in ThailandOriginal Paper

Thanapol Choochuen, Jiøí Foit, Ponthep Meunpong, Warong Suksavate

J. For. Sci., 2025, 71(6):297-311 | DOI: 10.17221/15/2025-JFS

The teak bee-hole borer [Xyleutes ceramica (Walker, 1865)] is considered one of the most serious pests of teak (Tectona grandis) in Thailand. The present study investigates climatic and topographic variables affecting the infestation of teak trees by X. ceramica in 10 plantations and predicts the risk of infestation by the species under current and future climatic conditions in Thailand. At each plantation, 48 plots evenly distributed among twelve teak stands were sampled. The infested teak trees in the plots were assessed, and the coordinates of the tree positions were recorded. The maximum entropy (MaxEnt) model was used to assess the effects of environmental factors and predict the occurrence probability of the species using current and projected (2050) climate data based on the Shared Socioeconomic Pathways SSP1-2.6 and SSP5-8.5 scenarios from multiple global climate models. According to our results, high accuracy values [AUC (area under the curve) = 0.852, TSS (true skill statistics) = 0.775] of the model prediction were obtained, and the infestation was found to be driven much more by climate than by topographic characteristics. Above all, X. ceramica was found to prefer moderate temperatures in a highly distinct seasonal climate. Additionally, relatively low amounts of premonsoon rainfall are also found to be favoured by the species. The predicted risk map revealed that the northern region is the core area of X. ceramica infestation in Thailand under current and future climatic conditions, but the severity of infestation is predicted to gradually decrease under the predicted future climatic conditions. Recommendations for management to minimise tree damage caused by X. ceramica are also presented in this study.

Increased uptake and accumulation of phosphorus and other nutrients by legumes enhance their bioavailability for non-legume speciesOriginal Paper

Peltier Aguiar, Margarida Arrobas, Manuel Ângelo Rodrigues

Plant 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.

Chau Thi Nhien, Cao Dinh An Giang, Brooke Kaveney, Jason Condon, Tran Duy Khanh, Dang Duy Minh, Nguyen Viet Long, Nguyen Van Loc, Chau Minh Khoi

Plant Soil Environ., 2025, 71(10):681-694 | DOI: 10.17221/317/2025-PSE

Vietnam’s Mekong River Delta (MRD), where rice is the dominant crop, is increasingly impacted by salinity intrusion, highlighting the need for alternative cropping options. This study evaluated the growth and yield performance of quinoa, beetroot, and maize under three irrigation salinity levels (0, 2 and 4 g/L), with and without rice straw mulch (7 t/ha), in greenhouse conditions representative of the MRD dry season. Agronomic traits, physiological parameters, and changes in soil, including electrical conductivity (ECe), soluble sodium (Sol-Na+), and exchangeable sodium percentage (ESP), were assessed. Results showed that quinoa demonstrated the greatest salinity tolerance, maintaining stable growth and yield under 4 g/L saline irrigation and soil ECe exceeding 15 dS/m. Beetroot’s yield was not significantly different under 2 g/L saline irrigation with straw mulching. Maize was highly sensitive to salinity and environmental stress, failing to complete its growth cycle under high heat and humidity, even in non-saline conditions. Across treatments, rice straw mulching significantly reduced soil ECe, Sol-Na+, and ESP, and improved crop performance under saline irrigation. Overall, quinoa and beetroot, especially when combined with mulching, offer promising alternatives for dry-season cropping in saline-prone areas of the MRD. In contrast, maize cultivation requires improved soil and environmental management under such conditions.

Perception of resilience and its determinants with a focus on farm size: The case of agricultural enterprises in the Czech RepublicOriginal Paper

Ilona Svobodová, Marie ©impachová Pechrová, Milan Takáè

Agric. Econ. - Czech, 2025, 71(8):458-474 | DOI: 10.17221/479/2024-AGRICECON

The aim of the paper is to examine the resilience of Czech agricultural enterprises through the perceptions of farm managers and to assess the areas where these businesses perceive themselves as resilient and where they feel vulnerable. The analysis is based on data from a survey conducted by the Institute of Agricultural Economics and Information (IAEI) in June 2022, involving 521 Czech agricultural managers. The study focuses on six key areas: climate change and its impacts, agricultural inputs, labour force, market outlets, land prices and availability, and changes in the Common Agricultural Policy (CAP). Across all areas, managers reported that businesses were more frequently vulnerable than resilient, particularly in relation to agricultural inputs and climate change. The results also highlight differences in the perception of resilience across enterprises of varying sizes, with significant variation noted in how changes to the CAP were viewed. Contrary to the common belief that larger enterprises are more resilient, the survey found that Czech medium-sized and large enterprises (with 200 hectares or more of agricultural land) were more frequently perceived as vulnerable.

Inter-specific cucurbitaceous rootstock enhances plant growth, photosynthetic, root architecture and yield traits in grafted cucumber (Cucumis sativus L.)Original Paper

Anant Bahadur, Anish Kumar Singh, Sapana Yadav, Rajeev Kumar, Hare Krishna, Tusar Kanti Behera

Hort. Sci. (Prague), 2025, 52(3):237-249 | DOI: 10.17221/96/2024-HORTSCI

In recent years, grafting has emerged as an efficient and alternative tool to the relatively slow conventional breeding methods, aiming to increase tolerance to abiotic stresses and soil pathogens while improving yield and quality attributes in fruit vegetables. In the present investigation, six inter-specific cucurbitaceous rootstocks, viz. sponge gourd (SG), ridge gourd (RG), ash gourd (AG), bottle gourd (BG), and Summerfit (SF), an inter-specific hybrid of snap melon × acidulus melon, were evaluated for cucumber (C) cv. ‘Kashi Nutan’. Experimental findings revealed that cucumber grafted onto inter-specific SF exhibited a 14.63%, 57.5%, and 20.05% increase in vine length, number of branches, and dry matter production, respectively, compared to the self-rooted control. Photosynthetic parameters such as photosynthetic rate (Pn), stomatal conductance (gs), and maximum quantum efficiency of photosystem II (PS II) (Fv/Fm) were also higher in cucumber leaves grafted onto the SF rootstock. Compared to self-rooted plants, cucumber grafted onto SF recorded 72.3% more fruits, a 36.9% increase in fruit weight, and an 80.9% higher fruit yield. The SF rootstock also showed a 44.54% increase in total root length (TRL), a 77.11% increase in root volume, and a 27.25% increase in average root diameter over self-rooted cucumber.

Hamid Reza Gazor, Omid Reza Roustapour

Res. Agr. Eng., 2025, 71(4):213-223 | DOI: 10.17221/43/2025-RAE


This study investigated the drying kinetics of Rosa flower buds (Rosa damascene Mill) under environmental conditions (shade), as well as in direct and indirect solar dryers. The effects of 40 °C, 50 °C, and 60 °C temperatures on the drying of the buds were also examined using a laboratory cabinet dryer. The drying rate of the Rosa flower buds was compared with various mathematical models, and the parameters of these models were evaluated. The results illustrated that drying Rosa flower buds under shade required a lengthy period time of approximately 13 days. In contrast, utilising solar dryers significantly reduced the drying period time for Rosa flower buds. Also, compared to the ambient drying method, the use of indirect solar dryers had the most substantial effect on decreasing the drying period time of the buds up to 86.6%. Furthermore, applying a temperature of 60 °C in the laboratory dryer reduced the drying time of the buds by 76.2% compared to a temperature of 40 °C. The Midilli et al. model (MDM), Page model (PM) and approximate diffusion model (ADM) demonstrated a good fit with the experimental data and can be employed to represent the drying behaviour of Rosa flower buds. The effective of moisture diffusivity of Rosa flower buds during drying was found to be in a range from 6.87 × 10–12 to 1.89 × 10–10 m²·s–1 and the activation energy values were determined as 65.30 and 72.80 kJ∙mol–1 for buds which were dried in the laboratory cabinet dryer and those dried using the ambient and solar dryer methods, respectively.

The impact of the integration of science, technology, and finance on innovation in listed agricultural enterprises through the lens of digital transformationOriginal Paper

Fanye Kong, Huini Zhong, Nana Chai, Baofeng Shi

Agric. Econ. - Czech, 2026, 72(2):84-100 | DOI: 10.17221/22/2025-AGRICECON

Digitisation enables the integration of science, technology and finance, and this trend toward integration can in turn enhance the innovation efficiency of listed agricultural enterprises. By leveraging the quasi-natural experiment of China's 2011 pilot program for technology finance – also known as science, technology, and finance, this paper uses the difference-in-differences (DID) model to demonstrate that the science and technology finance policy positively impacts the innovation levels of agriculture-related listed enterprises. That said, the policy's effect varies across different regions and enterprise sizes. Furthermore, moderating-effect analysis reveals that the digitalisation level of agriculture-related listed enterprises is a critical factor, while the evolutionary game model elucidates this factor's underlying mechanism. Based on these findings, policy recommendations are proposed to further develop science and technology finance platforms for agricultural-related listed enterprises.

Modelling the hydration process of wheat grain  with layer-dependent diffusion coefficientsOriginal Paper

Bakhtiyar Ismailov, Abdushukur Urinboev, Khairulla Ismailov, Akmaljon Kuchkarov

Res. Agr. Eng., 2026, 72(1):25-40 | DOI: 10.17221/101/2025-RAE

This study develops and validates a multilayer diffusion model of wheat grain hydration that incorporates layer-dependent diffusion coefficients for bran, endosperm, and germ. The moisture transport is formulated using Fick’s law with two interface formulations: (i) classical continuity of the concentration and flux and (ii) an interlayer resistance formulation that permits concentration discontinuities. Diffusion coefficients and geometric parameters were determined experimentally; A 3D grain model (structured-light scanning, COMSOL Multiphysics) informed the computational domain. Numerical solutions combined eigenfunction expansions with finite-difference discretisation near the interfaces. Across eight winter wheat varieties, the diffusion coefficients spanned 11.6 – 20.5 × 10–12m2·s–1 (mean 16.27 ± 3.08 × 10–12m2·s–1 ). Relative to the continuity model, the resistance model reduced the early-stage endosperm over-prediction by ~ 0.6–1.0 % (absolute) and lowered the whole-grain RMSE by ~ 20–30% over 0–240 min. These results support the role of thin moisture-retaining films as active barriers and yield smooth, real-time-ready outputs suitable for the automated control of pre-milling hydration; the framework is extensible to full 3D transient simulations.

The suitability of macadamia trees for different climates has been shown to affect tree growth and fruit quality. In this study, the differences in tree survival rate after frost injury, tree growth, nut mass, kernel quality and yield of seven macadamia cultivars were evaluated for field production in the high altitude and high latitude climate of southern Tibet, and the suitability of macadamia cultivars was determined. The cultivars evaluated were ‘Beaumont’ (‘HAES695’), ‘HVA16’ (‘A16’), ‘Hinde’ (‘H2’), ‘Own Choice’ (‘O.C.’), ‘SSCRI-1’, ‘SSCRI-2’ and ‘SSCRI-3’. Of these, ‘Beaumont’, ‘A16’, ‘H2’ and ‘O.C.’ were Australian cultivars and ‘SSCRI-1’, ‘SSCRI-2’ and ‘SSCRI-3’ were Chinese cultivars. The results showed that all seven cultivars grew well under the high altitude and high latitude climate conditions of southern Tibet without continuous frost. ‘A16’ and ‘Beaumont’ in addition to their reasonable yield, nut mass and kernel quality, had the higher tree survival rate after frost injury. ‘A16’ and ‘Beaumont’ were well adapted to the high altitude and high latitude climate of southern Tibet, followed by ‘O.C.’, ‘SSCRI-1’ and ‘SSCRI-2’, but ‘SSCRI-3’ and ‘H2’ were unsuitable. These results indicated that it is possible to produce macadamia in the high altitude and high latitude climate of southern Tibet by planting excellent frost-resistant cultivars, with promising yields and a commercial standard of nut quality.

Dairy cows enter the negative energy balance in the early post-partum period, which negatively affects milk yield, health status and reproduction. This study aimed to determine if milk yield (MY) and fat/protein (F/P) ratio could be used as reliable indicators for predicting the quality of aspirated oocytes and their further use for in vitro fertilisation. A secondary goal was to compare different periods before oocyte aspiration to determine which period had the most significant impact on the oocyte development in donor cows. All tested Holstein cows were at their first lactation (n = 68). The first ultrasound-guided follicular aspiration in donor cows was done on average at 58.7 days in milk (DIM). Usually, a second aspiration followed a week later if no problems were detected. In total, 102 aspirations were performed. Three model equations with different F/P ratio distributions and variants of MY production were tested in statistical evaluation. On average, 3.6 oocytes were retrieved per donor per aspiration, with a minimum of 1 and a maximum of 12. The maturation rate was 62.2%, with a high probability of reaching metaphase II (90.45%). The highest number of oocytes was obtained from low-yielding cows with a low F/P ratio in all evaluated periods (P < 0.01). The quality and expansion of cumulus-oocyte complexes were unaffected by the metabolic status. However, a tendency for better quality oocytes in donors with lower MY and F/P ratios was observed in all models. Our preliminary results showed that the prediction of oocyte quality in a homogeneous group of the first-lactation cows was related to the chosen data acquisition model. Data about milk yield and F/P ratio obtained from on-farm systems provide a valuable source of information for the selection of oocyte donors.

Bactrocera cucurbitae, commonly known as the melon fruit fly, stands as a formidable threat to global agriculture, particularly in the cultivation of cucurbitaceous crops. The adaptability, high reproductive capacity, and broad host range of B. cucurbitae make it a persistent challenge for growers worldwide. Conventional control methods, often reliant on chemical pesticides, pose environmental and ecological concerns, necessitating the exploration of alternative strategies for sustainable pest management. Invasive plants often exert deleterious effects on ecosystems, and the castor bean plant, Ricinus communis, is no exception. To explore the efficacy of R. communis, a methanol extract was tested to find the toxicity effect against B. cucurbitae. In this study, different bioactive compounds were isolated from R. communis. The crude extract of R. communis was subjected to fractionating using different organic solvents in an increasing order of polarity, where the fraction indicating maximum activity was then taken for the isolation of the bioactive compounds using various chromatographic and spectroscopic techniques such as column chromatography, thin layer chromatography (TLC), gas chromatography-mass spectrometry (GC-MS). The concentrations of R. communis extracts at 0.5, 1.0, 1.5 and 2% methanol were used. Pure methanol was used as the control. The experimental conditions were maintained at 28 + 20 ºC and 65 + 5% relative humidity. The experiment was laid out in a complete randomised design having five replications. A probit analysis was used to find the LC50 and LC90. The results showed that, as the concentration of the plant extracts increases, the mortalities of B. cucurbitae also increased. After a 72 h exposure period, the crude extracts exhibited the lowest LC50 at 0.30% and LC90 at 0.60%. This study investigates the potential of methanolic extracts derived from various parts of R. communis to serve as a biopesticide against B. cucurbitae which can be easily available, economically feasible, socially acceptable and environmentally friendly.

Zengjiao Wang, Yin Zhang, Deheng Zhang, Shenghao Zhang, Hongxiang Zhao, Zhen Liu*, Geng Li, Tangyuan Ning

Soil & Water Res., 2025, 20(3):153-163 | DOI: 10.17221/123/2024-SWR

To evaluate the effects of organic fertilizer and microbial agents on soil water and salt distribution, microorganisms, and crop yield on coastal saline-alkaline land, eight treatments were established, i.e., two maize varieties (Dajing Jiu 26 (J) and Quchen Jiu (Q)) and four organic fertilizer and microbial agent application methods (no organic fertilizer or microbial agent application (O0M0), single organic fertilizer application (O1M0), single microbial agent application (O0M1), and combined organic fertilizer and microbial agent application (O1M1)). The soil water content in the 40–50 cm soil layer under JO1M1 was 3.35% greater than that under JO0M0 at the mature stage. The soil organic carbon (SOC) and soil total nitrogen (STN) in the 0–10 cm soil layer under JO1M1 were 16.69% and 21.37% greater, respectively, than those under JO0M0 at the jointing stage. The actinomycete content was 58.79% greater in QO1M1 than in QO0M0. The urease activity was greater in O1M0 than in the other management practices. Compared with that in JO0M0 and QO0M0, the alkaline phosphatase activity in JO1M1 and QO1M1 was 47.36% and 33.97% higher, respectively. Compared with those of JO0M0, the catalase activity and sucrase activity of JO1M1 were 57.62% and 22.78% higher, respectively. Compared with JO0M0 and QO0M0, JO1M1 and QO1M1 increased the grain yield by 20.69% and 16.42%, respectively, and increased the biomass by 23.36% and 26.45%, respectively. In summary, organic fertilizer and microbial agents provide a scientific model for the rational use of saline soils and the development of their potential.

Contribution to the turbidimetric method for sulphur determination in arable soilsOriginal Paper

Olya Surleva, Katrin Chavdarova, Vilyana Kazanlaklieva, Lyudmila Angelova, Andriana Surleva

Plant Soil Environ., 2025, 71(10):695-707 | DOI: 10.17221/250/2025-PSE

Sulphur (S) plays an important role in agriculture, being the fourth major contributor to improved quality of crops and increased yields. The applied methods for the estimation of different forms of S in soil aimed at assessing the sulphur availability to plants in various conditions. Nowadays, the wider spreading of regions with sulphur deficiency imposes optimisation of the soil testing procedures in order to increase their availability for laboratories. This study contributes to improving the analytical performance of the turbidimetric method in determining water-soluble sulphate in soil after leaching with the CaCl2 reagent. The modified testing protocol showed: method limit of quantification of 5.0 mg/kg; precision as relative standard deviation less than 3%; recovery of fortified soil samples 103 ± 18%. The expanded uncertainty was 2.3 mg/kg SO42–-S (K = 2, norm.). The proposed testing protocol was inexpensive, fast, used simple equipment and procedures, easily adoptable in regular laboratories, and showed characteristics suitable for the estimation of water-soluble sulfate in arable soils. A set of 546 soil samples was tested, and 74% were found to be sulphur deficient with SO42–-S < 10 mg/kg and sulfur availability index < 6.0. Thus, the availability of laboratory analysis to a broader group of farmers could contribute to effective fertilisation programs, as the newly proposed fertiliser blending technologies are based on adequate estimation of sulfur availability in arable soils.

Indonesia, as a leading coconut producer, generates a substantial amount of coconut pulp from coconut milk extraction, which can be further processed into low-fat desiccated coconut. However, the drying process induces browning, reducing its whiteness and overall quality. Sodium metabisulphite is commonly used to prevent browning, but excessive use raises health concerns. In this study, the optimisation of the drying temperature and sodium metabisulphite concentration was conducted to minimise the browning while maintaining the quality of low-fat desiccated coconut. Using Response Surface Methodology (RSM) with a Central Composite Design (CCD), responses such as the browning index (BI), whiteness index (WI), moisture content, yield, free fatty acids (FFAs), ash, fat, protein, total phenolic content (TPC), and crude fibre were examined. The results showed that both the drying temperature and sodium metabisulphite concentration significantly influenced the physicochemical properties. The optimal conditions were identified at 62.505 °C and 380.059 ppm sodium metabisulphite, resulting in a whiteness index of 87.219, browning index of 5.1025, yield of 43.125%, moisture content of 2.3%, and free fatty acid content of 4.45%. These findings highlight an effective strategy for reducing the additive dependency while maintaining the physicochemical quality of low-fat desiccated coconut.

Plant Soil Environ., 2025, 71(11):770-781 | DOI: 10.17221/310/2025-PSE

The effect of mineral, organic (manure or straw + intercrop) and combined fertilisation on the development of soil nutrient contents over time and their mutual ratios was evaluated in a long-term field trial, IOSDV (established in 1984 at two sites), differing in the soil-climatic conditions. Three cropping cycles, from 2016 to 2018, 2019 to 2021, and 2022 to 2024, were studied in the following crop rotation: winter wheat-winter barley-root crop (sugar beet at Ivanovice na Hané and potatoes at Lukavec). Potassium and phosphorus in mineral fertilisers have not been applied since the year 2020 due to their high content found in soils after dry years with low yields. Consequently, their content decreased, most in the third rotation, both by the Mehlich 3 method and especially the exchange fraction extractable with NH4-acetate (Ivanovice: P 5–14%, 32–40% and K up to 12%, 9–20% determined by Mehlich 3 and NH4-acetate, respectively; Lukavec: Mehlich 3 – P increase: 5–16%, K decrease: 0–8%; NH4- acetate decrease – P: 10–13%, K 8–23%). The mutual ratio of nutrients equivalents K : Mg : Ca was lower than required values 1 : 2–3 : 10–15 at both sites and all studied treatments, however a slight increase was observed during the studied period, above all in system with only mineral fertilisation (Ivanovice: K : Mg : Ca from 1 : 1.2 : 5.6 to 1 : 1.4 : 6.8, Lukavec: from 1 : 1.0 : 7.7 to 1 : 1.0 : 9.6). A correctly balanced ratio of nutrients in the soil is important for maintaining soil fertility. In this long-term field experiment, the increase in nutrient levels in soils over reasonable levels was observed, highlighting the necessity of regular nutrient testing in agricultural soils, especially when multiple types of fertilisers are used simultaneously.

The response of carabid beetles to extensive livestock farming and vegetation structure in two traditionally managed 'dehesa' ecosystems was investigated. From March 2011 to January 2012, sampling was done, using pitfall trapping, on two forestry farms located in the Sierra de Hornachuelos Natural Park (Córdoba, Spain), both with hunting use, but one of them also with a heavy livestock load. On each forestry farm, two sampling plots were selected according to the vegetation structure. Faunal differences were proved through the ecological indices, and the faunal uniqueness was checked by the Coldwell and Coddington Complementarity Analysis. To identify the most influential factor on the carabid biodiversity, a Generalised Linear Mixed Model (GLMM) was performed. Results show that abundance and richness are higher in the plots with open vegetation, similarly like the number of recorded tribes. Nevertheless, the ecological indices do not reflect any significant differences. The complementarity between different vegetation structures exceeds that of the exploitation types. In fact, the GLMM analysis indicated that the livestock itself does not have a significant effect on the fauna. In addition, all exclusive, rare or endemic species came from the closed vegetation plots, suggesting that these areas may act as a reservoir of unique species in terms of biodiversity.

To enhance the biomechanical database of plant root systems for soil reinforcement and erosion control in arid and semi-arid regions, and to provide a scientific basis for selecting superior native shrub and herb species in forestry and grassland measures for desertification control in central and western Inner Mongolia, this study investigated the root-soil interfacial friction characteristics of five typical native plant species – Caragana korshinskii and Hippophae rhamnoides, the semi-shrub Hedysarum mongolicum, and the perennial herbs Medicago sativa and Astragalus adsurgens – in two widely distributed non-zonal soils: loessial soil and aeolian sandy soil. Single-root pull-out tests were conducted on indoor-prepared root-soil composite samples to examine their responses to varying soil moisture levels. The results showed that within a soil moisture range of 4.6% to 20.6%, the single-root pull-out resistance and shear strength of all five species in both soil types followed a quadratic model Yax2 + bx + c (with all multiple correlation coefficients > 0.5), initially increasing and then decreasing with rising moisture content. Peak values occurred at 8.6% moisture, with consistently higher values observed in loessial soil than in aeolian sandy soil. This indicates an optimal soil moisture level for maximising root-soil interfacial friction resistance. Among the species, Hippophae rhamnoides and Medicago sativa exhibited superior pull-out performance in both soils, with Hippophae rhamnoides showing greater sensitivity to environmental variations in loessial soil. Redundancy analysis identified soil type and moisture content as key factors explaining variations in root pull-out shear strength. These findings demonstrate that mixed-species plantations, leveraging complementary root traits, can form more complex and stable root-soil structures, thereby enhancing surface soil mechanical stability. Further research is needed to elucidate the adaptive mechanisms linking plant traits, environmental conditions, and biomechanical characteristics.

Thawed meat is usually of lower quality and less expensive than chilled meat, which some dishonest people may exploit by fraudulently marketing it as chilled. This study focused on methods for detecting and distinguishing frozen meat from chilled meat. The activity of the enzyme aconitase in the eluate was determined, and the mineral cations (Na+, K+, Mg2+) as well as the concentrations of organic acids (acetic, citric, and lactic) were analysed in chilled and thawed meat stored for 7, 14, and 150 days at −18 °C. After 150 days of storage, aconitase activity increased from 47.2 ± 7.2 U·L–1 to 395.3 ± 59.2 U·L–1 in pork, from 45.8 ± 11.5 U·L–1 to 133.3 ± 31.8 U·L–1 in beef, and from 17.2 ± 8.6 U·L–1 to 143.6 ± 41.5 U·L–1 in chicken. The mineral content decreased during storage in meat samples, especially Na+ and K+ cations (P < 0.05). The results for organic acids were less conclusive. Principal component analysis (PCA) of the data confirmed a clear separation between chilled and thawed meat for all species, with a high variability of nearly 72%.

The research was conducted in a long-term stationary experiment established on light grey forest surface-gleyed soil in 1965. Data presented in this study were collected during 2022–2024 growing seasons within the framework of this long-term experiment. The experiment is registered in the NAAS long-term field experiments registry (certificate No. 29) and the Global Long-Term Agricultural Experiments Network (GLTEN). The study examined the effect of growing red clover in a four-field crop rotation on nutrient balance at different fertiliser and lime doses and ratios. Red clover was used for feed and feed-green manure purposes. The research aimed to substantiate optimal methods of utilising this valuable forage crop and optimise fertilisation systems to ensure sustainable agricultural development. Growing the first cut of red clover for feed purposes and the second as green manure with fertilisation (N105P101K101 + organic fertilisers + liming) ensures a positive surface balance of 402 kg/ha of nitrogen, 150 kg/ha of phosphorus, and 204 kg/ha of potassium. These data are almost twice higher than indicators under minimal fertilisation doses. Despite the reduction in symbiotic nitrogen fixation from 217 kg/ha to 147 kg/ha when growing red clover in crop rotation with intensive fertilisation, it remains an effective phytobiological ameliorant.

The need of vernalisation, controlled by the gene VRN-1, impacts wheat adaptation and yield stability, yet field evidence on the plasticity of VRN-1 homoeologs expression is limited. We quantified VRN-1 homoeolog dynamics across two sites and two seasons in seven cultivars, by sampling their apex and leaf. VRN-A1 varied with genotype (P < 0.001***), tissue (apex > leaf; P < 0.001***), apex development (P < 0.001***), day length (P < 0.001***), and to a lesser extent, on short-term freezing exposure, quantified as a 5-day freezing-degree sum (FDS; P = 0.019*). Photoperiod class (Ppd-D1a vs Ppd-D1b) added an additional effect (P = 0.001***). VRN-B1 showed strong genotype effects (P < 0.001***), a modest effect of site on its expression (P = 0.025*), and pronounced associations with microclimate variables (day length, thermal sums, freezing exposure; all P < 0.001***). Directionally, Ppd-D1a backgrounds tended to advance the development while showing earlier apex VRN-A1 peaks. Overall, VRN-A1 expression mainly reflected developmental stage and seasonal forcing, whereas VRN-B1 might be more microclimate-responsive, indicating complementary roles for timing and stress-response plasticity. To isolate causal effects and to further explain these dynamics, targeted sequencing and tests in near-isogenic lines will be needed in future work.

To date, ‘Japansche Citroen’ (JC) has only been used commercially as a rootstock in Indonesia; however, the use of suitable rootstock remains challenging because of water limits in different places. The morphological, physiological, and gene expression changes of one-and-a-half-year-old mandarin cv. ‘Keprok Batu 55’  (KB) and sweet orange cv. ‘Manis Pacitan’  (MP) budded onto ‘Japansche citroen’ (JC), ‘Rough Lemon’ (RL), ‘Salam’ (S), ‘Volkameriana’ (V), and ‘Cleopatra Mandarin’ (C) rootstocks, subjected to six-week drought-stress conditions, were examined under a shade house. The experiment was conducted in Junrejo Subdistrict ( ± 990 m a.s.l.), Batu City, East Java Province, Indonesia, from January 2022 to May 2023. The experimental design was a factorial randomized block design with two factors: rootstocks as factor I and two citrus species as factor II, with three replications. A low shoot/root (S/R) ratio indicates much more root development than shoots observed in KB/C (0.89) and MP/RL (0.87) plants under drought conditions; the MP/RL plant had the greatest stomatal density (16.0/0.015 mm2) and percentage of stomatal closure (58.8%). In this condition, it had lower leaf relative water content (RWC) than the control, with comparatively high RWC ranging from 45–55% in KB/JC, KB/S, MP/C, and MP/RL. The drought did not affect cell membrane damage, although this did slightly increase the quantity of chlorophyll a, b, and carotenoids (P < 0.05). Aside from that, leaf proline and total soluble sugar levels were higher in the dryness than in the control, with the combination of KB/C (331.6 μ mol proline/g fresh weight), MP/JC, and MP/RL plants having the highest (347.9 and 337.1 μmol proline/g fresh weight). Meanwhile, the plants with the greatest quantities of soluble sugar were KB/C (35.9 mg/g dry weight) and MP/V (75.3 mg/g dry weight). Regardless of scion-rootstock interaction, KB enhanced the relative quantity of several genes such as 1-Aminocyclopropane-1-carboxylate (ACC) synthase, Chlase, ethylene receptors (ETR1), osmotin, plasma membrane instrinsic proteins (PIP1), and PIP2 allowing it to respond more effectively to drought stress conditions. In contrast, MP only increased Chlase and ETR1 ones. Under drought conditions, the KB/C and MP/RL combinations are assumed to be more adaptable than others.

Sows are selected for their prolificacy. Therefore, assessing difficulties that can be associated with large litters is crucial. This review aims to highlight the factors that can affect reproductive performance such as breed, parity, litter size, environment, and nutrition. Understanding these factors can help producers make informed decisions about sow management and other aspects. Higher within-litter variation is the result of  a  high number of piglets born. It has been determined that large litter sizes pose a risk to animal welfare in the pig industry. Moreover, large litters bring more piglets with low birth weight leading to high pre-weaning losses. Lighter littermates struggle to get enough colostrum due to the competition with heavy littermates, which lowers their chances of survival causing high mortality. Larger litters may cause greater stress and discomfort of the sow. Therefore, applying stress-free environment and treating the sow with anti-inflammatory compounds may enhance the sow performance and consequent survival of piglets. The litter size is positively correlated with the variation in birth weight within a litter, while the average weight at birth is negatively related to litter size. Producers should therefore focus on potential management strategies that can improve piglet performance, survival and welfare such as proper supervision and adequate colostrum intake. This review highlights the historical development of the pig industry and literature on the variation in piglet weight at birth within a litter, factors influencing weight at birth, and the potential effects on the piglet performance before weaning. Also, the difficulties amongst large litters and possible strategies for managing survival in large litters were also reviewed.

Addressing social sustainability, gender dynamics, strengthening educational diversity and ensuring inclusive partnership structures are all key components of promoting inclusion, not only in the agricultural sector. Diversity management is a human resource trend based on respect for inclusive culture, gender and ethnic diversity, multifaceted equality or the use of virtual teams under the right working conditions, but when not applied correctly it may produce undesired effects in agribusinesses as well as in other economics sectors. This paper aims to identify effective approaches to setting working conditions used by organisations to promote inclusion, management diversity and the development of social sustainability. The data were obtained through quantitative research using the Computer Assisted Web Interviewing method (n = 202) and processed using the chi-square test at a 0.05 significance level as well as through qualitative research involving focus groups (n = 10). The study results have demonstrated that investment in diversity education remains crucial. Not only agricultural but also other businesses have begun to use metrics to monitor their diversity and inclusion progress. Organisations are beginning to use artificial intelligence (AI) to remove prejudices in recruitment, identify inequalities in remuneration and ensure inclusion in online communication.

Effect of gypsum and potassium fertilisation on the nutritive value of legume-grass mixtureOriginal Paper

Waldemar Zielewicz, Barbara Wróbel

Plant Soil Environ., 2025, 71(2):93-108 | DOI: 10.17221/274/2024-PSE

The four-year field trial was conducted at the Rolnicze Gospodarstwo Do¶wiadczalne Brody (Brody Experimental Farm), Poznañ University of Life Sciences, Poland. This study aimed to assess how different doses of gypsum and potassium (K) fertilisers influenced the nutritive value of the alfalfa-grass mixture. The following two experimental factors were duplicated: gypsum fertilisation – two levels (0 and 500 kg/ha) and K fertilisation – four levels (0, 30, 60, and 120 kg/ha). The sward was harvested three times at the full budding phase of alfalfa. The content of nutritive components: crude protein (CP), crude fibre (CF), crude ash (CA) and water-soluble sugars (WSC) by NIRS technique was assessed. The combined application of gypsum and K significantly increased the yields obtained only in the 1st and 3rd harvests of the sward. In the case of CP and WSC, the application of gypsum and K showed no significant effect on the content of these components in the sward. At the same time, it significantly influenced the higher content of CF and CA only in the case of the 2nd harvest. Analysing the influence of only the effect of K on the results obtained, a response of increasing CF content in the sward under the influence of increasing doses of this nutrient was noted. The average potassium content of the sward increased from a K0 fertilisation level to an application rate of K60. In the case of CA content, there was a successive increase with the application of successive fertilisation rates from K0 to a rate of K120. Based on the average yield results, a similar response was observed for the increase in yields obtained with increasing potassium fertilisation rates from K0 to K120. CP content increased due to gypsum fertilisation, as did the achieved sward yields of the alfalfa-grass mixture. The biomass of the alfalfa-grass mixture without gypsum fertilisation contained more WSC than the fertilised one.

A rapid evaporative ionization mass spectrometry (REIMS) method combined with intelligent knife (iKnife) method was developed to explore the geographical origin and characteristic differential components of Qianbei Ma lamb. The REIMS conditions were initially refined, with the cauterization duration of 3 seconds, and the auxiliary solvent flow rate set to 100 μL·min–1 to prevent duplication. A database model was created from raw data through the proposed principal component analysis-linear discriminate analysis (PCA-LDA) in Live ID software, successfully applied to identify samples from 5 provinces in China and the real-time reliable identification rate with confidence higher than 99%. The obtained data by REIMS were used to establish the multivariate statistical models which using orthogonal projection to latent structures discriminant analysis (OPLS-DA), provided strong the discrimination power between composition and content changes of 16 specific ions such as m/z 726.3952 and m/z 744.4050, etc., including fatty alcohols, fatty acids and phosphatidylserines in mutton of different origin and the model displayed validation [R2(Y) = 0.968, Q2 = 0.924].

Has contract farming improved the green technology efficiency of vegetable growers? Empirical evidence from rural areas in Shandong Province, ChinaOriginal Paper

Qi Li, Zixuan Wang

Agric. Econ. - Czech, 2025, 71(7):378-393 | DOI: 10.17221/43/2024-AGRICECON

Contract farming is regarded as an effective strategy for smallholder farmers in developing countries to enhance their agricultural competitiveness. However, limited research exists on its potential to promote green, sustainable development. This paper investigates the impact of contract farming participation on farmers' green technology efficiency using data from a sample of 627 vegetable growers in Shandong, China and employs the propensity score matching method. Our findings are as follows: i) Under the counterfactual assumption, participation in contract farming increases green technology efficiency from 0.560 to 0.614. The efficiency of contract production bases, ranked from highest to lowest, is as follows: self-owned base, stock-sharing base, and contractual base. ii) The provision of productive services serves as a significant mediating factor in enhancing green technology efficiency, with a more substantial impact than issuing planned instructions. iii) Increasing purchase prices, as an effective means of providing motivational incentives, significantly amplifies the effect of contract farming on green technology efficiency in self-owned and stock-sharing bases. As organisational models evolve toward greater integration, the enhancing effect of price incentives on green technology efficiency strengthens. This study concludes with several public policy and agricultural management recommendations.

Forest bathing is gaining attention for its health and well-being benefits, leading to growing interest among academics, policymakers, and practitioners. While most studies have focused on its physiological and psychological effects, less is known about how different stakeholders perceive the characteristics that make forest bathing effective and meaningful. This study explored expert and non-expert perspectives on forest bathing in Italy through the Q-methodology, aiming to identify shared and divergent views on key aspects such as site features, accessibility, and perceived benefits. The results highlighted four distinct viewpoints: a scientific-health-oriented perspective emphasising medical efficacy (mainly experts); a preference for more naturalness and ecological integrity (mainly non-experts); a possible socio-economic opportunity (mainly non-experts); and a preference for a more managed forest environment with supporting structures (mainly experts). Despite differences, consensus emerged on several points, including the cultural and physical relevance of forest bathing and the importance of inclusive accessibility while preserving low-impact environments. The findings highlighted the potential of Q-methodology to capture the plurality of stakeholder voices, offering a basis for more inclusive planning and policy development in the context of nature-based well-being initiatives.

This study aimed to evaluate the effects of hop extract in the form of xanthohumol (XA) and humic substances (HS) supplementation in the rabbit diet on growth performance, carcass traits, blood biochemical parameters, and the qualitative and sensory properties of rabbit meat. Experimental material consisted of 60 Big Light Silver × Chinchilla Giant crossbred rabbits, randomly assigned to three dietary groups. Experimental groups, XA and HS, were fed pellets enriched with 1.0% XA or 1.0% HS, respectively, for 63 days during the fattening period. Control group (C), consisting of rabbits that received a basal diet without supplements. In the XA group, the higher final live weight and carcass weight were recorded at the end of the fattening period, along with increased protein content and collagen-free muscle protein (BEFFE) in the leg and loin muscles, compared to the control group. In contrast, the HS-supplemented group exhibited the lower final live weight and carcass weight, along with reduced fat content in the leg and loin muscles, as reflected in lower blood cholesterol levels. Additionally, elevated blood serum calcium and phosphorus levels were observed in the HS group. Higher values of colourimetric parameters L* and h* (lightness and hue angle) were recorded in the leg meat of the XA group compared to the control group. Moreover, the results demonstrated that supplementation with 1.0% XA was more effective in delaying lipid oxidation in meat compared to the control group on the 7th day of refrigerated storage. In conclusion, the primary benefit of supplementing rabbit diets with 1% xanthohumol is improved growth performance, positively influenced by increased protein content, reduced fat content, and enhanced oxidative stability of the meat.
