Weeds have a negative impact on the productive, quality and economic indicators in the production of bird's-foot-trefoil forage. The control against them is increasingly becoming a general ecological problem, which necessitates the need to look for new approaches to eliminate them. The implementation of systems and activities for sustainable agriculture is related to control over the use of plant protection preparations. This necessitates consideration of issues related to the application of appropriate agrotechnical practices to improve soil fertility and preserve useful cultivated species in grasslands from an economic point of view. Correlation dependences and derived regression equations were calculated on the sown grass from bird's-foot-trefoil treated with the herbicides Kalam in a dose of 20 and 40 g/da and Focus ultra in a dose of 100 and 200 ml/da. It was found that imported herbicides authorized for use showed a high positive correlation between yield with gross revenues (r=1.0000) and profit (r=0.9999). Graphical models have been developed to predict the main economic indicators based on the yield obtained after treating the grass with herbicides.

The fruit-growing sector in Romania faces continuous challenges related to climate variability, production efficiency, and market competitiveness, requiring farmers to adopt cultivars with high adaptability and profitability. This study analyzes the yield performance of two plum cultivars, 'Anna Späth’ and 'Stanley’, cultivated under the agroecological conditions of the Moara Domneasca Experimental Base, aiming to provide a scientific basis for economic optimization in fruit-growing farms. The data were collected during the 2024 production season, focusing on fruit yield per tree, biometric indices (fruit weight, height, diameters), physico-chemical traits (firmness, pH, soluble solids). The results indicate that 'Anna Späth' produced smaller but sweeter fruits, with an average weight of 16.5 g, mean height of 32.2 mm, and sugar content of 18.9% °Brix. In contrast, 'Stanley’ recorded larger fruits, averaging 22.9 g in weight, 42.9 mm in height, and superior firmness (2.25 kgf/cm2), though with a slightly lower sugar content of 16.5% °Brix. Morphological traits such as fruit diameters were consistently higher in 'Stanley', confirming its better structural quality and storage potential. These findings underline clear cultivar-specific differences, with 'Anna Späth’ offering a sweeter profile, while 'Stanley’ provides larger, firmer fruits more suitable for commercial markets. The findings support decision-making processes in farm management by identifying 'Stanley' as the most advantageous cultivar from an economic perspective, thus contributing to improved resource allocation and long-term sustainability in the Romanian plum sector.

In this article, we have analyzed how innovation in agriculture is reflected and articulated in the international scientific literature, with a special focus on the role of associative forms, such as cooperatives and producer groups. The main goal was to understand how types of agricultural innovation are defined and disseminated and to what extent they are influenced or facilitated by collective farmer organizational structures. The approach was guided by two objectives: identifying the main types of innovation applied in agriculture and carrying out a bibliometric analysis that would highlight the structure and dynamics of scientific knowledge in this field. The methodology was based on querying the Scopus database, using relevant terms such as agricultural innovation, farmer associations and economic performance. The data obtained were processed using VOSviewer, to generate thematic maps that analyze networks of co-citation, keyword co-occurrence, international collaboration and bibliographic coupling. The results obtained show that, although the topic of agricultural innovation is intensively treated, the relationship with associative forms remains peripheral in the specialized literature. The bibliometric networks show a pronounced conceptual fragmentation, with thematic clusters evolving in isolation, some focused on technology and adoption, others on rural development or sustainability, without a coherent integration of the organizational dimension. In addition, the lack of common theoretical sources and insufficient standardization of terminology affect the coherence of the scientific field and its capacity to produce transferable explanatory models. The general conclusion emphasizes the need for interdisciplinary and integrative approaches, which more clearly connect technological innovation with social and institutional processes in agriculture. It is also recommended to valorize associative forms as active vectors of innovation, not just as an organizational background, in order to advance towards a more complete understanding of the transformations in contemporary agriculture.

Akçakoca is a district in Türkiye known for its unspoiled natural landscapes, historical landmarks, and rich cultural heritage. For the past 50 years, it has played an important role in tourism and is strategically located at an equal distance from two of the country’s largest cities. Alternative tourism is new opportunity for Akçakoca district besides mass tourism. The goal of this research study is to assess Akçakoca region potential to develop rural tourism. To achieve this, the perspectives of local residents engaged in rural tourism were examined. A quantitative research approach was adopted, and data were collected through face-to-face surveys. Using a convenience sampling method, responses from 175 participants were analyzed. The findings indicate that in order to enhance rural tourism in Akçakoca, greater emphasis should be placed on investment, promotion, and infrastructure. Expanding tourism activities throughout all four seasons, increasing local awareness, and distributing tourism revenues more evenly are seen as key steps toward sustainable regional development. Furthermore, collaboration among local authorities, tourism enterprises, and the community is essential for designing effective strategies. In this regard, encouraging greater participation of women and young people in tourism initiatives is expected to strengthen the positive impact of rural tourism on the local economy.

This research aims to analyze how social networks contribute to the promotion of local gastronomy in the context of contemporary Romanian tourism. In a period when tourists are no longer looking for just destinations, but authentic and culturally relevant experiences, gastronomy is becoming a central element in the process of selecting and valorizing the places visited. Social networks play an increasingly important role in this process, providing not only inspiration, but also direct influence in decision-making regarding culinary and tourist consumption. A quantitative methodology, implemented through the use of a structured questionnaire, was employed to support the analytical approach. Its goal was to record the respondents' sociodemographic traits as well as their attitudes and behaviors regarding food consumption in tourist settings and the impact of social networks. The research instrument was applied online and was completed by a number of 137 people. The results obtained show that the vast majority of respondents prefer authentic traditional food during the holidays and appreciate local restaurants, agrotourism guesthouses and regional street food. Regarding the digital environment, Booking, Facebook, Instagram and Tripadvisor are the most frequently used platforms for tourist inspiration, and the types of content considered to have the greatest impact are stories about local producers and reviews from other tourists. Over 78% of respondents say that they have chosen a restaurant or guesthouse based on the visual or narrative content found on social networks, which confirms the direct influence of the digital environment on tourist consumption behavior. The conclusions led us to the idea that the research conducted confirms that social networks represent an essential channel in promoting local gastronomy, not only from a commercial perspective, but also as a vector of cultural identity. The consumer public is increasingly attracted to authenticity, stories, the relationship between the product and the place of origin, and social networks facilitate precisely this closeness. From this perspective, tourist communication must be strategically rethought, so as to combine visual professionalism with narrative sincerity, and local gastronomy becomes an integral part of the image and attractiveness of each destination.

Food and beverages are basic physiological needs and are essential elements of a healthy diet and survival. Thus, although food prices increase, there is no significant change/decrease in the total food demand of the individuals. This study was conducted to determine the role of the food and beverage sector in Türkiye's economic structure, and to analyze the correlation between the sectoral enterprise and the Consumer Price Index (CPI). The main material of this study consists of data organised from the "Annual Industry and Services Statistics", "Foreign Trade Statistics", "Household Consumption Expenditures Statistics", and "Consumer Price Index (CPI)" of the Turkish Statistical Institute (TURKSTAT). The data were analysed in a computer-aided programme. According to the findings of the research, it has determined that the food and beverage sector has a significant share in the manufacturing industry. In the 11-year period, the export value of the sector increased by 81.8%, and reached 22 917 million USD. In the 13 years, 12.0% of the employees in the manufacturing industry were employed in the food and beverage sector. In the period analysed, the number of enterprises in the sector also increased along with the CPI. CPI increased 14.1 times, and the number of enterprises in the sector increased 1.7 times. In the study where CPI data were regarded as the independent variable and the number of enterprises in the sector as the dependent variable, and analysed with the single linear regression model, it was detected that the relationship between the variables was statistically significant. The study serves as a reference in terms of raising awareness on the economic importance of the food and beverage sector.

Unite Finite Element Analysis- FEA model has been developed containing material properties, loads, fixtures, constraints and connections among all parts, faces and edges of the suspension system components. FEA analysis showed that U-bolt is a critical component of this suspension system. Simulation study analyzed both U-bolt diameter and doubling the Quantity of U-bolts from four to eight U-bolts. Von-Mises stresses, displacements and Shear stresses have been monitored and analyzed. U-bolt diameter has gradually increased with 2mm steps from 20mm to 22mm to 24mm for a first configuration with four U-bolts and second design configuration with eight U-bolts. Taking into consideration available materials, manufacturing methods and cost in Egyptian market showed that using the first design configuration with four U-bolts of 24mm diameter decreased the maximum von-Mises stress, displacement and shear stress on the U-bolts from 775 to 547 MPa, 4 to 2.4 mm and 335 to 222 MPa respectively instead of using the same configuration with 20mm diameter U-bolts. A more durable option is using the second design configuration with 24mm diameter U-bolts which decreased the maximum von-Mises stress, displacement and shear stress on the U-bolts from 775 to 321 MPa, 4 to 2.19 mm and 335 to 108 MPa respectively. The results showed the importance of CAD software for improving the design process of the suspension system with minimum cost and time. Also, the effects of using thicker U-bolts and doubling their quantity were noticeably observed. The allowable shear stress of the U-bolt material is 254 MPa, after running FEA analysis the maximum shear stress on U-bolts has been reduced to 222 MPa and 108 MPa for both design configurations and the shear stress ratio were 0.874 and 0.425 respectively which make both design configuration safe for operation. The total cost of imported bogie suspension system worthed 3,447 US dollars. while the total cost of the local manufactured bogie suspension system for the 1st consideration and 2nd consideration were 3,257.4 and 3,358.6 US dollars respectively. The local component percentage of the local manufactured bogie suspension system for the 1st consideration and 2nd consideration were 51.602% and 53.06% respectively.

The decline in livestock numbers in the Central and Eastern European Countries (CEECs) in the last decade has affected not only the regional meat production but also the trade flows. This paper examines the evolution of livestock and meat imports in the CEECs over the past decade, a period marked by a significant rise in meat imports across most of these countries. The method is quantitative based on data sourced from ITC and Eurostat. Findings reveal that the leading livestock producing countries in the region are also major importers. Additionally, countries such as Spain, Germany, and the Netherlands — which hold a large share of the EU’s livestock — play a key role in meeting the meat import demand of the CEECs. Romania and Poland, which account for the largest share of livestock within the CEECs, along with the Czech Republic, also rank among the top meat-importing countries in the region. Excepting poultry meat sector, all the other sectors are depending on the imports from the Western Europe.
