The aim of the study is to evaluate the influence of selected growing factors on the production, quality, and composition of fatty acids. The field small plot experiments were stablished on research-experimental base in Dolná Malanta in 2018 and 2019. Growing factors and experimental material used in this study were hybrids Carrera, SY Gracia, Marbelia CS and Reasun DS-5 grown by Clearfield and Clearfield Plus technology, and biostimulating preparations Florone (made from hydrolyzed plant proteins formulated with NPK) and Fertisilinn (foliar fertilizer with orthosilicic acid and micronutrients). Statistical analyzes confirmed the significant influence of the year on all monitored parameters of the experiment. For achieved yield and fatty acid content (oleic acid, palmitic acid, and stearic acid) was more favorable experimental season of 2018. Experimental year 2019 was more suitable for creation of yield-forming elements, oil content, and linoleic acid content. Used hybrids significantly affected the head diameter, weight of thousand achenes, yield, oil content, oleic, linoleic, palmitic, and stearic acids. Significant differences between hybrids were achieved mainly in qualitative parameters (oil content, linoleic, palmitic, and stearic acids). The biostimulating preparations significantly affected yield-forming elements (head diameter, weight of head, and weight of thousand achenes), yield and quality (oil content, and all fatty acid composition), from which it follows that the application of biostimulating preparations affects the main production parameters, and the quality of the oil through fatty acid content. The very strong negative relationship (r=-0.9951; P < 0.01) in fatty acid composition between oleic and linoleic acid was found. In the other side very strong positive relation (r= 0.9882; P < 0.01) between number of plants and number of heads was recorded.

The purpose of the study is to estimate the frequency of bulls of the Ukrainian black-and-white dairy breed that are carriers of the recessive allele of the CD18 locus of cattle and to propose measures to reduce its prevalence. The analysis showed a high frequency of the recessive BLAD (BL) in the Ukrainian bulls belonging to Holstein-derived breeds. Lack of control over the spread of this hereditary congenital disorder has led to the uncontrolled use of BLAD carrier bulls. The the bovine CD 18 locus was conducted on 30 bulls of the Ukrainian Black-and-White dairy breed. It was found that 90% of bulls had the unaffected genotype at the CD18 locus (TL/TL), and 10% were heterozygotes (TL/BL) and could potentially spread the disease. As a result of studying the pedigrees and genotypes of animals, the authors propose measures to control the spread of the BLAD mutation in the dairy herds of Ukrainian Black-and-White dairy breed.

In this study, we present the first data on the sexual dimorphism and diet of a typical desert lizard species, Scincus scincus, in the region of El-Oued, southeastern Algeria. The objective was to characterize the types of prey in the diet and determine whether there is a correlation between prey size and body size in males and females. The results obtained reveal that out of the 115 individuals captured (43 males and 72 females), sexual dimorphism is observed. Males tend to be larger than females, with males exhibiting relatively larger snout-vent length, head height, head length, and jaw length compared to females. However, no difference is recorded in terms of head width. The analysis of stomach contents allowed us to identify 485 prey items distributed among 9 prey categories, all attributed to insects. Coleoptera was the most commonly ingested prey category, accounting for 61.54% of stomachs, 59.79% of total prey items, and 62.41% of total volume. A similar diet was observed between females and males of S. scincus, with a high diet overlap (O = 0.99) and a low diversity of prey types ingested by both males (Ba = 0.17) and females (Ba = 0.19). Coleoptera represented the most dominant order in the skink's diet, followed by the Hymenoptera order. Generally, the remaining seven taxa were consumed in low proportions by both sexes. Additionally, we observed no significant difference between the number of prey consumed and the volume of prey between the sexes, and no correlation was found between morphometric characteristics, diet composition, and prey volume.

Field trials were conducted in the early cropping seasons of 2014, 2015 and 2016 at Federal University of Agriculture, Abeokuta (7° 20‘ N, 3° 23‘ E) Nigeria to evaluate intercropped cucumber and jackbean as supplements to pre-emergence herbicides on growth and yield of maize. The treatments were arranged in a split – plot arrangement fitted into Randomized Complete Block Design (RCBD) with three replications. The six main plot treatments consisted of maize at 100 × 37.5 cm intercropped with cucumber, maize at 100 × 37.5 cm intercropped with jackbean, maize at 75 × 50 cm intercropped with cucumber, maize at 75 × 50 cm intercropped with jackbean, sole maize at 100 × 37.5 cm, sole maize at 75 × 50 cm, completed the treatments as controls. Eight treatments were assigned to the sub – plot. Data collected were subjected to Analysis of Variance while significant means were separated using Duncan`s Multiple Range Test (p <0.05). Sole maize at 75 × 50 cm and the intercrop with jackbean consistently produced significantly higher (p <0.05) shoot dry matter, compared to other cropping patterns while maize intercropped with cucumber depressed the aforementioned parameter. Propaben at 1.6 kg a.i·ha-1 followed by (fb) supplementary hoe weeding (SHW) resulted in higher stand count, vigour score, shoot dry matter and maize cob yield relative to other weed control methods. Therefore, maize should be planted at 75 × 50 cm with or without jackbean and sprayed with Propaben at 1.6 kg a.i·ha-1 fb SHW as this gave the maximum values.

The purpose of this study was to determine whether short-term consumption of 100% sea buckthorn juice (SBJ) affects serum lipids and body composition in hypercholesterolemic women. The study included 31 non-medicated adult women aged 40 to 56 years (average age 49.86 ± 5.98 years). In this intervention study, volunteers received 50 mL of 100% bio commercial SBJ every day for 4-week period. Anthropometric and biochemical parameters were monitored before and after 4 weeks of consumption of SBJ. Body composition was determined using an multifrequency analyzer InBody720. Routine biochemical analyzes were performed by standard methods in an accredited laboratory of the University Hospital by automatic biochemical analyzer BioMajesty JCA-BM6010/C. Supplementation with 100% SBJ increased high-density cholesterol (P <0.05) and decreased low-density cholesterol (P >0.05). There was also a positive decrease in the LDL-C/HDL-C ratio (P <0.01) and C-reactive protein (P <0.001). We observed a significant weight loss (P <0.05), body fat (P <0.01), body mass index (P <0.05) and visceral fat area (P <0.01). The obtained results show that the daily consumption of SBJ for 4 weeks represents a possible prevention of risk factors for cardiovascular diseases (CVD) in hypercholesterolemic women without pharmacotherapy.

The aim of this work was to identify and quantify the relationships between dry matter content and key energy nutrients (water-soluble carbohydrates and starch) in silage maize hybrids ( Zea may s L.) during vegetation development in the foothills of Slovakia. This work summarises the results of 9 experiments carried out at three locations (2016 to 2021: 140 different hybrids; 1,320 measured samples). Dry matter content was determined by a combination of gravimetric determination and measurement of water content in dried samples using the NIRS method (prediction model R 2 0.987). We also determined the content of water soluble carbohydrates (prediction model R 2 0.994) and starch (prediction model R 2 0.978) in dry matter using the NIRS method. Using 3 rd and 4 th degree polynomial models, we evaluated the contents of these nutrients at a dry matter content level of 300 g.kg -1 , which we can consider as a basic starting point for reaching maize silage maturity. Across individual years, and across groups of hybrids grouped according to silage maturity determined by dry matter content, water soluble sugar content reached 140 g.kg -1 of dry matter and starch content reached 280 g.kg -1 of dry matter at a dry matter content of 300 g.kg -1 . We found the lowest variation coefficient (7.53%) when evaluating the relationship between dry matter and the sum of water-soluble carbohydrates together with starch. We suggest using this parameter as a second criterion for determining silage maturity, and also for classifying hybrids in silage maturity groups with rounding to a ten day period.

The value of soybean varieties in terms of general combining ability (GCA), constants of specific combining ability (SCA) and their variances in terms of productivity elements in two-tester top-cross crossings were determined. Differentiating ability of Hoverla and KyVin testers was revealed. The degree and frequency of positive transgressions in hybrid populations were established.There were established high effects of general combining ability by plant height and height of attachment of lower beans in Sawyer 2-95 variety and KyVin tester; by the number of productive units in Sawyer 2-95 variety and Hoverla tester; by pod number per plant in Sawyer 2-95 and Kyivska 97 and Hoverla tester; by seed number per plant in Kyivska 97 and Medea varieties and Hoverla tester; by 1,000 seed weight in Sawyer 2-95 and Kyivska 97 varieties and Hoverla tester; by seed weight per plant in Medea and Kyivska 97 varieties and Hoverla tester; in terms of yield in Medea variety and Hoverla tester. It was found that additive effects of genes were dominating in genetic control of the traits of plant height, height of attachment of lower beans, number of productive nodes, pod number per plant, seed number per plant, 1,000 seed weight, seed productivity and yield, the share of non-additive effects of the gene interaction was lower, however, it was also reliable. Analysis of dominance indicators revealed combinations of crosses that were distinguished by overdominance of these traits and had significant breeding value: Sawyer 2-95 × Hoverla, Kyivska 97 × Hoverla, Medea × Hoverla.

Bacterial wilt disease caused by Ralstonia solanacearum is a devastating plant disease on potato plant. This study aimed to screen endophytic bacteria isolated from potato roots planted in middle latitude areas and confirm their antagonistic potential against R. solanacearum. Endophytic bacteria were isolated from healthy potato roots (Granola cultivar) grown in the middle latitude area (500–700 m.a.s.l.) in Bumiaji Sub-District, Batu City, East Java, Indonesia. In this study, 130 endophytic bacteria were isolated. As a result, eight endophytic bacterial isolates were found as potential antagonists against potato wilt diseases (R. solanacearum) i.e., E1, E5, E6, E104, E117, E120, E121, and E129. Based on in vivo test, E1 isolate reduced the bacterial wilt disease in potato by 20.74% and significantly increased plant growth (plant height and plant dry weight). The ability of the endophytic bacteria to produce the antibiosis substance against the R. solanacearum and their ability to reduce bacterial wilt disease in vivo suggests that those bacterial isolates have the potency to be developed as the candidates for biocontrol agents against bacterial wilt disease caused by R. solanacearum. However, it is necessary to identify the molecular bacteria isolated in this study to determine which species can suppress wilt disease and increase the growth of potato plants.

As a result, eight endophytic bacterial isolates were found as potential antagonists against potato wilt diseases (R. solanacearum) i.e., E1, E5, E6, E104, E117, E120, E121, and E129. Based on in vivo test, E1 isolate reduced the bacterial wilt disease in potato by 20.74% and significantly increased plant growth (plant height and plant dry weight). The ability of the endophytic bacteria to produce the antibiosis substance against the R. solanacearum and their ability to reduce bacterial wilt disease in vivo suggests that those bacterial isolates have the potency to be developed as the candidates for biocontrol agents against bacterial wilt disease caused by R. solanacearum. However, it is necessary to identify the molecular bacteria isolated in this study to determine which species can suppress wilt disease and increase the growth of potato plants.","PeriodicalId":7312,"journal":{"name":"Acta Fytotechnica et Zootechnica","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135855826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was focused on a production potential of tall wheatgrass (TW) and perennial rye (PR) grown in marginal and contrasting soil climatic conditions under the following mineral nutrition: (a) intensive nutrition of 245.0 kg/ha NPK, (b) semi-intensive nutrition of 122.5 kg/ha NPK and (c) untreated control of 0.0 kg/ha NPK. The large-scale pilot field experiments with two varieties of TW: Szarvasi-1 and Alkar as PR: Kriszta and Gergő were carried out on 4 research sites during 4 years (2016/17 to 2019/20). Despite the contrasting soil conditions, yields were variously affected by (i) nutrition, (ii) site, (iii) variety and (iv) year (the order based on their F-ratios). A dry matter (DM) yield of 5.29 t/ha on average was found, it ranged from 0.01 to 13.46 t/ha. Average - minimal - maximal variety yields were as follows: Szarvasi-1 6.01 - 1.05 - 13.46 t/ha, Alkar 5.86 - 0.62 - 12.90 t/ha, Kriszta 5.06 - 0.01 - 13.21 t/ha and Gergő 4.25 - 0.05 - 10.60 t/ha. Under intensive or semi-intensive nutrition both crops are suitable for all types of tested marginal soils. TW better tolerated unexpected water-logging that occurred on Site-2 with heavy clay soil than PR, while PR is more suitable for light sandy soil. The following average DM yields were obtained under intensive nutrition on the most productive Site-3 with heavy soil: 11.77 t/ha Szarvasi-1, 10.14 t/ha Alkar, 8.01 t/ha Kriszta and 7.75 t/ha Gergő, whereas on Site-1 with light sandy soil under intensive nutrition the following average yields were achieved: 7.74 t/ha Gergő, 7.72 t/ha Kriszta, 6.29 t/ha Szarvasi-1 and 5.17 t/ha Alkar. PR had about 148 mm less precipitation on average when compared to TW (187 vs. 334 mm) because of earlier harvest time while the average daily temperature was lower by about 1.9 °C on average (16.3 vs. 18.2 °C). As to varieties Kriszta and Gergő, it is probably one of the first original research papers published and probably the first research based on large-scale experiments of PR from the time when it was recognized as an energy crop.

1,2-propanediol (propanediol) represents an important glucoplastic substance for the nutritional requirements of highly productive cows, and its natural synthesis during silage fermentation is of great importance. The aim of this paper was to monitor the fermentation activity of two combinations of homo- and hetero-fermentative lactic acid bacteria (LAB) in two preparations (preparation 1: L. buchneri, L. rhamnosus, L. plantarum; preparation 2: L. buchneri, L. rhamnosus, L. diolivorans). Propanediol production was monitored in maize silages at the following levels: cutting technology, hybrid, vegetation development, type of silage fermentation and length of fermentation time. From the point of view of silage alternatives, preparation 1 fulfilled the declared properties and had a demonstrably positive influence on the production of propanediol in maize silages from whole plants (average content of 4.93 g.kg-1). Propanediol production in the silage alternative with preparation 2 (average content of 1.33 g.kg-1) was higher when compared to the negative control (average content of 0.11 g.kg-1). The production of propanediol decreased with increasing dry matter content, which is directly related to the advancing vegetative development of plants. The type of silage fermentation and vegetation development had a statistically demonstrable effect on the level of propanediol production in maize silages. A statistically significant difference at the hybrid level was only identified with one hybrid. No statistically significant differences were found at the level of cutting technology and length of fermentation time. The fermentation activity of the Lactobacillus buchneri strain used depended on its combination with other homofermentative and/or heterofermentative LAB strains.
