In the context of a growing population and the increasing demand for sustainable protein sources, edible insects – particularly crickets – are emerging as a highly promising alternative food option. This article focuses on synthesizing and analyzing existing research related to the nutritional composition of cricket powder from various geographical sources, such as Thailand, Kenya, and Canada. Cricket flour has been reported to contain high levels of protein (42.0–48.87%) and fat (23.6– 29.1%), along with essential minerals such as potassium (826–1 224 mg/100 g), iron (4.06– 5.99 mg/100 g), zinc (2.17– 21.8 mg/100 g), etc. — micronutrients that are vital for human health. The variation in nutritional content among samples indicates the role of the species of cricket, the feed, the rearing conditions, and the processing methods. When incorporated at substitution levels of 2–50% compared with conventional ingredients, cricket powder demonstrates great potential as both a meat alternative and a functional ingredient. Its diverse nutritional profile makes it suitable for specialized applications in the food industry. Overall, this overview clarifies the potential applications of cricket powder in the future food system, supporting directions toward sustainability, safety, and improved nutrition.

Historic gardens are important but often undervalued heritage monuments. The paper presents the development of the heritage protection of the historic gardens and parks but reminds also the importance of the nature protection in the gardens. The study area is the Krsn Dvr garden in western Bohemia (Czech Republic), which represents one of the first landscape gardens in the Czech lands. This garden is presented in European garden history context. The main focus is on the compositional analysis that has not been performed yet. Not only old maps but also historical descriptions and paintings were used to conduct this analysis. Terrain research was inevitably utilized for evidence of the present state. Krsn Dvr garden is a typical example of early landscape gardens influenced by the picturesque and anglo-chinois style. The composition consists of many closely situated and relatively small bits of scenery that usually do not appear to communicate among themselves. It was demonstrated in this study that many follies and vistas are still preserved today. The compositional analysis could serve as a basic material to inform garden presentation and reconstruction.

The effect of enriching the diets of young quails in the direction of meat productivity with dry garlic powder in different concentrations was studied. For this purpose, four groups of one-day-old quails of the Pharaoh breed were formed, each consisting of 100 birds. The experiment lasted 35 days and was divided into two periods (1–21 days and 22–35 days). During the experiment, quails were kept in single-tier cage batteries and fed a complete feed mixture that met the recommended standards according to the age of the quails. The diet differed only in the content of garlic powder. In particular, young birds of group І (control) received only a complete feed, while 0.3% dry garlic powder was added to the diet of quails of group ІІ, group ІІІ – 0.6% and group ІV – 0.9%. It was found that the introduction of dry garlic powder into the diet of young meat quails at a concentration of 0.6% provides higher growth rate by 1.1% (p < 0.05) and live weight by 5.4% (p < 0.001) without reducing the survival of the population. The quality of quail meat has also improved, namely increased in pre-slaughter live weight by 5.1% (p < 0.05), the weight of unguilted, semi-gutted and gutted carcasses by 5.4–5.8% (p < 0.05), as well as the weight of pectoral muscles by 5.0% (p < 0.05), leg muscles by 5.1% (p < 0.001), skin by 9.3% (p < 0.05), internal fat by 20.0% (p < 0.001) and liver by 0.4 g or 7.1% (p < 0.05), with an increase in the yield of edible parts by 3.1% (p < 0.05) and a decrease in bone density by 3.1% (p < 0.05). Correlation analysis confirmed that increasing the concentration of garlic powder in the quail diet is associated with improving their meat productivity and slaughter qualities. Therefore, the most effective concentration of introducing dry garlic powder into the diet of young meat quails is 0.6%.

70% of the decline in agricultural production is caused by abiotic stress factors, such as than drought and variations in precipitation. Its factors can pose problems in terms of starting the small- seeded species in the early stages of vegetation (germination) and crop informing in plant growth. Camelina (Camelina sativa L. Crantz, Brassicaceae) is an important low -yield oilseed crop consumption of inputs. Camelina East considered as small- seeded species, this setting can directly influence seedling germination, growth and development. The current research East based on the study of germination and growth of sevens varieties of camelina. Germination tests have summer conducted at the laboratory level, and growth tests have summer posed on the ground according to a completely randomized block experimental design with three repetitions. The results revealed significant differences (p < 0.05) between the different seven varieties for germination capacity, emergence, number of plants in rosette and precocity. Variety 7 is the best performing variety for the parameters studied: it has excellent germination capacity (98.66%), it produces 7 plants per 31 square centimeters, 10 rosette plants per 31 square centimeters and it is the earliest with duration of 48 days from sowing to 50% flowering.

Wild turkeys (Meleagris gallopavo L.) are considered a promising source of high-quality poultry meat. The aim of this study was to evaluate the meat yield and selected physicochemical properties of semi-wild wild turkeys, including water, protein, fat and cholesterol content, amino acid and fatty acid profiles and meat colour. The average carcass yield without head was 79.56%. The water content ranged from 69.25 (breast) to 71.39 g/100 g (thigh), the protein content from 23.19 (thigh) to 26.24 g/100 g (breast) and the fat from 0.95 (breast) to 2.03 g/100 g (thigh). Cholesterol content was lower in breast (41 mg/100 g) and higher in thigh (56 mg/100 g). Significant differences (P ≤ 0.05) in amino acid composition were found between breast and thigh muscles. Fatty acid composition was significantly different (P ≤ 0.05), especially in DHA, EPA, omega-3, omega-6, PUFA and SAFA levels. Breast muscle showed higher lightness (L* = 41.03) and lower redness (a* = 1.27) and yellowness (b* = 6.56) compared to thigh (P ≤ 0.05). The results confirm that wild turkeys raised in semi-wild conditions produce nutritionally valuable meat with desirable physicochemical properties, making them suitable for sustainable and functional poultry meat production.

The aim of this research was to evaluate the decomposition and release of nitrogen, phosphorus, and potassium in the biomass of two green manures: Canavalia ensiformis (L.) and Mucuna deeringiana (Bort) Merr. After incubation in the soil, they were treated with mountain microorganisms (MM). An experiment was proven in the experimental agricultural field of the Faculty of Agronomic Sciences of the Autonomous University of Chiapas, Mexico, in Villaflores, Chiapas. The decomposition bag technique was used, and the following treatments were evaluated: C. ensiformis+MM, C. ensiformis- MM, M. deeringiana+MM, and M. deeringiana-MM. A randomized block design with a factorial arrangement was used; each bag with 10 g of dry matter inside was buried 15 cm deep in the soil. Three bags per treatment (six samplings) were removed every two weeks from the soil. The material was recovered, and the remaining dry biomass was quantified by difference. N was determined by the Kjeldahl method, P by colorimetry and K by atomic absorption spectrophotometry. Significant differences (p < 0.05) in the evaluated variables showed a gradual decomposition and nutrient release trend. C. ensiformis+MM showed higher decomposition with 97.68% and 93.02% in C. ensiformis-MM, while M. deeringiana+MM, and M. deeringiana-MM obtained 83.94% and 82.82%. The release of N, P, and K, irrespective of treatments, showed ranges of 44.77-253.97, 8.13-44.49 and 4.75-27.35 mg/10 g green manure, respectively. The application of MM in green manures accelerated their decomposition, and release of nutrients to the soil.

This study examines the influence of seasonal conditions and hybrid selection on the yield-forming parameters, seed yield, and oil content of sunflower (Helianthus annuus L.). The research was carried out as a field experiment on the plots of AGRO SAP s.r.o., located in the village of Nenince, Slovakia. Four sunflower hybrids (ES Poetic, ES Electric, SY Talento, Marbelia CS) were selected to monitor the variability of the selected parameters during the growing seasons 2020-2022. The statistical analysis of the collected data confirmed a highly significant effect of the studied factors on productive traits of sunflower. Over the study period, the average yield of sunflower was 3.48 tonnes per hectare (t/ha), with an average oil content of 38.92%. Among the climatic factors analyzed, precipitation distribution had the greatest influence on oil content, while temperature fluctuations were the key factor affecting seed yield. The seasonal conditions of 2020 was the most favorable for yield-forming parameters, recording the highest head diameter (176.6 ± 0.82 mm), head weight (182.83 ± 8.46 g), and thousand seed weight (TSW) (64.58 ± 2.23 g). However, 2021 provided optimal conditions for seed yield (3.79 ± 0.24 t/ha) and oil content (40.51 ± 0.51%). Among the hybrids, Marbelia CS excelled in yield-forming traits by head diameter (168.5 ± 1.51 mm), TSW (64.33 ± 2.34 g), while ES Poetic showed the highest seed yield (3.69 ± 0.36 t/ha) and ES Electric recorded the highest oil content (39.43 ± 1.15%). These findings highlight the importance of seasonal climatic conditions and hybrid selection in sunflower cultivation, providing essential insights for optimizing yield and oil production.

The aim of this study was to evaluate the composition of the protein complex and some other selected values (e.g. the representation and proportion of amino acids in crude protein) of linseed cake from the flax (Linnum sativum) variety 'Kostanay 11', which is widely grown in the Republic of Kazakhstan. The values were chosen to assess the suitability and benefits of including 'Kostanay 11' in livestock and poultry feed. This cake composition of the 'Kostanay 11' variety was then compared with the 'Northern' and 'Golden' flax varieties, which are more widely grown in the area. The amino acid composition of linseed cake was further compared with other cakes used for feeding livestock and poultry. For example, soya and sunflower products, which are the most popular worldwide. Only for this new variety of linseed - Kostanay11 (and only for linseed cake) was the chemical analysis carried out directly in the Institute's laboratory. The values obtained were then compared with those given in the standards used by the feed industry. All the research and subsequent data comparison leads us to the conclusion that the linseed cakes of the new Kostanay 11 variety are fully sufficient as one of the components of feed for animal nutrition. According to our findings, its nutritional value is not only equal to that of other flax varieties grown in Kazakhstan, but in many parameters, it even reaches the quality of the most desirable soybean cakes.

Fennel seeds in poultry feed positively affect productivity and health. To determine the optimal dose of fennel seed powder in complete feed mixtures for meat-type quails, a scientific and economic experiment was conducted on Pharaoh quail chicks. Four groups of one-day-old quails, each consisting of 100 birds, were formed for the experiment. The control group was fed a basic feed mixture, while the experimental groups received the same mixture with 1-2% fennel seed powder. After a seven-week experiment, it was established that the doses of fennel seeds used positively influenced the productivity and slaughter characteristics of the quails. However, the highest indicators of average daily body weight gain, slaughter weight, and yield were achieved with the inclusion of 1.5% fennel seed in the quail feed. Therefore, incorporating 1.5% fennel seed into the feed for meat-type quails aged 1-42 days can be considered optimal.

The article presents three Carex nothospecies new to the flora of the Czech Republic found in 2024 directly in the field and through revision of specimens in the larger Czech herbaria. We found Carex felixii (= C. acutiformis C. elata) at two localities and five more records by revising herbarium specimens. Carex prahliana (= C. lasiocarpa C. rostrata) was found at three sites, and Carex viadrina (= C. buekii C. cespitosa) is now also known from three localities. In addition, we publish here six more records of Carex alluvialis, a hitherto missing hybrid in the Czech Republic, which we found at two localities, while the other records are the result of a revision of herbarium specimens. The text of the article is accompanied by photographs of plants found in the field.
