Romania's biodiversity is a natural treasure, offering a vast array of species and ecosystems, but faces increasing threats from human activities and climate change. Education, awareness and conservation of biodiversity are key to protecting this priceless biological diversity. In this article, through statistical methods of analysis, we aim to explore the role of education and awareness in the conservation of Romania's biodiversity, highlighting initiatives and efforts to promote public understanding and commitment to protecting the environment and unique species. This analysis allowed us to identify relevant patterns, trends and conclusions related to biodiversity education, awareness and conservation in Romania. Protecting Romania's biodiversity is therefore not only a necessity for the environment, but also for society, the economy and human well-being. Biodiversity conservation is essential for our well-being and the health of the planet, and it is our responsibility to act on it. We will explore the importance of education in schools and universities, the role of NGOs and government actions, and their impact on biodiversity conservation in the country.

The aim of the study was to study the effectiveness and provide an economic assessment of the use of various insecticides against pests on alfalfa seed crops in the second year of the grass stand. The research was conducted during 2019–2021 at the experimental field of the Institute of Irrigated Agriculture of the NAAS. Treatment with insecticides was carried out: the first – in the phase of the beginning of budding, the second - before the beginning of flowering. The use of insecticides reduced the number of pests on the grass stand. The most effective in the fight against pests (with the exception of Aphis craccivora Koch) was the preparation with the active substances Chlorpyrifos, 500 g/l and Cypermethrin, 50 g/l and the consumption rate of 1.00 l/ha. The highest seed yield was obtained in the first treatment with an insecticide preparation with the active substances Chlorpyrifos, 500 g/l and Cypermethrin, 50 g/l and the consumption rate of 1.00 l/ha, and in the second treatment with preparations with the active substances Chlorantraniliprole, 200 g/l and Lambda-cyhalothrin, 50 g/l at a rate of 0.17 and 0.15 l/ha, respectively. When irrigated with this variant, the seed productivity was 635.2 kg/ha, which was higher than the control variant by 115.3 kg/ha. Under conditions of natural moisture, the seed yield was 452.5 kg/ha, and was higher than the control by 74.3 kg/ha. The lowest cost price of 0.66 €/ha and the highest conditional net profit of 1702.87 €/ha was obtained on the option: the first treatment - Chlorpyrifos, 500 g/l and Cypermethrin, 50 g/l, the second – Chlorantraniliprole, 200 g/l and Lambda-cyhalothrin, 50 g/l.

The paper aimed to study the effectiveness of corn cultivation under different irrigation methods on the experimental field of the Askanian State Agricultural Research Station, which is located in the semi-arid, steppe, arid climate zone of the Southern Steppe of Ukraine, in the Kakhovsky irrigated massif. The investigation pointed out the effectiveness and provided an economic assessment of the use of different irrigation methods in corn cultivation. Two methods of irrigation (sprinkling and subsoil drip irrigation) were studied, with the maintenance of the humidity of the soil layer 0–50 cm at the level of 80% LMC and corn hybrids of different maturity groups. Under subsoil drip irrigation, the irrigation rate was lower on average by 24% than when sprinkled, on the other hand, the yield was higher on average by 40.9%, which significantly affected the cost price of the obtained corn grain. Subsoil drip irrigation yielded a net profit of 62% higher than sprinkler irrigation. and the profitability accordingly increased by 78.8%.

Biological treatment is the technological process by which organic impurities in wastewater are transformed by a culture of microorganisms into harmless degradation products (CO2, H2O, other products) and new cell mass (biomass). The microorganism culture is then dispersed in the reaction volume of the sewage treatment plant, forming activated sludge. The aim of this work was to present the efficiency of wastewater treatment from the food industry using the operating principle of a biological activated sludge treatment plant in a meat processing plant. The methods of determining the indicators that highlight the quality of wastewater from the meat processing unit were those according to the STAS in force, and the determinations were carried out in the laboratory of the Călărași Environment Protection Agency. Following the analysis of the 5 wastewater samples taken in the period March-July 2023, it could be remarked that regardless of the volume of wastewater entering the treatment plant and the amount of kg of meat processed per day, the treated water leaving the treatment plant meets the requirements for discharge into the natural outfall according to NTPA - 001, except for the indicator total phosphorus, which at concentrations higher than 35 mg/L in the wastewater before treatment cannot be brought below the maximum permitted value of 1 mg/L for discharge into the natural outfall. The efficiency of the treatment plant, analyzed for 10 indicators is good, ranging from 70.22 - 99.63%. So, biological treatment with activated sludge is an efficient treatment technology in such a unit, inexpensive, clean and environmentally friendly.

The present work studied the role and efficiency of internal communication in the production activities within the agricultural structures in the Western Region of Romania. Internal communication can be a key element in addressing and solving the major challenges posed by the current competitive environment in the field.This research provides a comprehensive analysis of communication processes within organisations with an agricultural profile, addressing a knowledge gap in the research literature in this field, enhancing the understanding of the role of communication in agriculture. In this context, the main aim of this researchis to investigate various factors like flow, coordination, barriers, communicational efficiency, actuality, frequency, and the effectiveness of communication channels in the context of Western Romania’s agricultural holdings. The present study employs a quantitative approach, surveying 503 respondents from 40 agricultural holdings, and uses network analysis and correlation matrices in order to understand communication patterns and the relationships among these factors. The findings highlight the need for customized communication strategies to accommodate differences in age, education, and professional backgrounds among staff. They also stress the importance of using multiple communication channels for timely information exchange, the impact of channel choice on information flow, and the importance of addressing communication barriers. Overall, the study underscores the significance of strategic communication in agriculture for efficiency and coordination among employees, suggesting potential future research in this area.

The share of agricultural exports in the structure of the total export of goods from Ukraine was analyzed. The geographical structure of the export of goods from Ukraine, in particular the agro-industrial complex, was studied. Special attention was paid to the issue of the change in the structure of the export of goods in 2022. The structure of the export of products from Ukraine, in particular agricultural products, was studied in terms of partner countries. Special attention was focused on considering changes in the structure of exports in 2022 in Ukraine. In 2022, the logistics of exporting agricultural products became significantly more complicated. Neighbouring European countries felt a significant burden during the restructuring of the logistics channels for the export of Ukrainian agricultural products before the opening of the «grain corridor». Customs crossings, railway infrastructure and the infrastructure of sea and river ports of the European Union countries were fully involved. In the article, we substantiated that in order to unblock the export of agricultural products from Ukraine through the domestic Black Sea seaports, the significant burden of building export logistics flows was taken on by European neighboring countries, which fully utilized all their logistics infrastructure. In 2022, there was a reduction in the export of agricultural products, and in 2023, its further decline is predicted. Using the example of grain crops, polynomial approximation was used to forecast their gross harvest, as well as calculate domestic consumption and export potential in 2023. The study indicates that in 2023, export revenue from the sale of grain crops should be expected to be more than twice as much as in 2021.

This study aims to determine the factors affecting compliance with Sustainable Rice Platform (SRP) standards in rice production in the Mekong Delta, which is considered the largest rice granary in Vietnam and is of great importance in the world rice export market. The study was conducted based on survey data for 426 rice-growing households and implementing SRP standards in the region by 2022. The study results showed that only 6.57% of rice-growing households could fully comply the SRP standard, while the majority of households encountered certain obstacles. The analysis results from the binary regression show that some factors that positively affect the compliance with SRP standards are the education level of the household head, the size of rice land and contract farming. Meanwhile, large demographic size has a negative effect on compliance with SRP standards. In addition, infrastructure factors such as intra-field road condition and post-harvest straw collection services are community-level constraints affecting compliance with SRP standards. Based on the results of this study, some solutions and policy implications are proposed.

Rural development is the effort to ensure the economic, social, and cultural development of these communities in a democratic way, by first creating a sense of need for individuals and communities living in rural areas and making their living from the agricultural sector or similar rural occupations. For improving and optimizing Sustainable Development Goals (SDGs) approaches for rural livelihoods, it is essential firstly to monitor and evaluate the current situation on SDGs in target villages and its achievements, also to identify the challenges and opportunities in this area. The purpose of study is to conduct surveys for assessment of current situation on SDGs and identifying opinions and understandings of farmers/producers and extension providers/input suppliers on this issue in farms located in Tovuz, Agstafa, Gadabay and Tartar districts in Azerbaijan. In the study, primary clients were farmers and secondary clients were extension providers/input suppliers including different representatives from the public and private sectors. During study, we identified the main pre-conditions, such as the technical, finance and economic problems, natural resources and hazards that farmers face in agriculture, as well as main difficulties faced by farmers in accessing agricultural extension services/trainings, also annual production volume and income on the farm and other difficulties faced by farmers for achievement of SDGs in farms. In the study, data were collected by face-to-face survey method from 47 farmers and 5 extension providers selected by random sampling from Tovuz, Agstafa, Gadabay and Tartar districts. Simple statistical methods were applied in the evaluation of the data obtained, and average and percentage calculations were performed. According to the results, farmers are facing some challenges preventing the achievement of SDGs such as finance and economic problems, natural resources and hazards, and technical issues in agriculture. To eliminate the negative effects of urbanization in target villages, there is a great need to improve rural income sources and promote employment for people in rural areas.

For beekeepers, understanding the honey base in their area is crucial to producing quality honey. Placing hives in locations with adequate nectar and pollen sources can lead to honey production with area-specific properties. In addition, knowledge of the honey flora in a certain region can help identifying optimal times for nectar collection. It is also important to monitor and manage the honey flora in order to maintain bee health and ensure the availability of food sources. This research has two objectives: identification of the honey flora in Sibiel village, Sibiu county, Romania and the quality analysis of honey collected from the area. The honey bee flora was analysed according to several classification criteria: botanical, by the type of food provided to the bees, by biological and economic criteria. In the laboratory, the following quality analyses of honey samples from the four hives studied were carried out: acidity index, electrical conductivity, pH and water content determination. The results obtained show that Sibiel has a honey production base that ensures maintenance, development and even production for upcoming years, and that the honey is a natural, high quality product with high chances of certification.

The study used imaging analysis to describe and characterize a soybean crop, in terms of plant uniformity and the presence of weeds, with the formulation of intervention decisions for crop management. Images were taken in digital format (cell phone camera), which were analyzed for spectral information (RGB) and fractal geometry (D). Based on the obtained data, normalized values (rgb), different ratios (R/G, R/B, G/R, G/B, B/R, B/G), specific indices (NDI – normalized difference index, INT - intensity) and degree of vegetation cover (DVC, %), as green canopy cover. A flow diagram was developed for the study carried out in the assessment of soybean culture. From the correlation analysis, the values of the correlation coefficient (r) were obtained, in conditions of statistical safety. The regression analysis led to obtaining some equations that described the variation of DVC in relation to the considered parameters. Very high levels of precision and safety were recorded based on the R/G ratio, the corrected g value (R2=0.998, p<0.001), followed immediately by the equations based on the G/R ratio and the NDI index (R2=0.997, p <0.001). 3D models and in the form of isoquants described the variation of DVC in relation to the considered parameters. According to PCA, PC1 explained 95.997% of variance, and PC2 explained 3.9978% of variance. Cluster analysis led to the grouping of the variants based on similarity, highlighting the variants with a high degree of weeding (s8, s9), the variant with a normal state (s7) and the other experimental variants.
