The adjustment of educators and pupils to the technological modifications enforced on the educational process during the epidemic is a crucial factor for forthcoming educational reforms. So, the primary objective of this study was to assess the perception of teachers and students in the pre-university setting regarding their adaption to technology during the period of 2020-2022. The data was collected in 2022 by administering questionnaires to a sample of 100 teachers and 100 students. It is important to note that 53% of the teachers and 59% of the students surveyed come from rural areas. The results revealed significant disparities between the participants (teachers and students) in terms of their utilization of IT resources and their level of engagement in online coursework (7 out of 11 items). Disparities were also identified between the instructors and the students originating from urban and rural regions. The findings illustrate the impact of respondents' IT skill and engagement in the learning process on their technological response patterns from 2020 to 2022.

This article uncovers relationships between the wine export and production in Armenia. Wine industry is a strategically important economic sector in Armenian. The importance of its development is strongly supported by the fact that alcoholic beverages from grape processing are products with high customs value exported from Armenia (in 2020 the share of alcoholic beverages in the entire export structure was about 8.4%). Within the framework of this study, a detailed analysis of the wine production was performed. By applying econometric analysis, we assessed the impact that the increase of wine export has on wine production. Also, the empirical analysis of the impact of USD and RUB exchange rates on wine industry was performed. Overall, the econometric analysis indicated that export volumes and USD exchange rate significantly affect Armenian wine industry. This study provides enough evidence for us to conclude that the export of Armenian wine must be heavily promoted by Government policies and the same time the export directions must be diversified. The results of this study can be basis for scientific substantiation of sectorial strategies developed by the Government of Armenia.

The article studied the productivity indicators, the effectiveness of the use of feed and medical and preventive means, as well as the economic indicators for the rearing of piglets using dry feeding (from self-breeders), wet feeding (from automatic feeders), liquid feeding (prepared in containers for a building for rearing) and portioned liquid feeding (prepared at each individual automatic feeder). Better indicators of piglet productivity were found with liquid feeding and portioned feeding of piglets by hydration during feeding in the automatic feeder. In liquid feeding, piglets had 4.34–20.62% better average daily and absolute growth, 3.42–15.24% higher weight at the end of the period, but were 0.03–0.53% worse in terms of preservation than analogues using dry and wet feed. When using a liquid feeding system with feed mixture in containers designed for one room, the productivity indicators proved to be lower compared to feeding with portion feeding systems, but they outperformed the animals with dry feeding by 15,6% in terms of average daily and absolute gains and by 11.43% in terms of weight at the end of rearing, and they outperformed analogues consuming moistened feed in the feeder by 10.77% in terms of average daily and absolute gains and by 7.81% in terms of weight of piglets at the end of rearing. Piglets consuming wet feed during rearing were inferior to their liquid-fed counterparts in terms of key productivity indicators, but showed better productivity levels than their dry-fed peers.

As a solution to mitigate the effects of climate change, scientists have been looking for more environmentally friendly energy production alternatives, so, since the 2000s, renewable energy production has increased across Europe. Climate change has a negative impact on our planet, with increased emissions of greenhouse gases contributing to global warming. In this context, biogas has become a promising solution for reducing greenhouse gas emissions and improving environmental quality. The purpose of the study is to review the evolution of research and development in this field, identify trends and gaps in existing knowledge, and assess the impact and significance of published research. In this sense, a bibliometric analysis was carried out, based on the topics "renewable energy" and "biogas", in which VosViewer software was used to create maps. The research results show that existing policies worldwide encourage transfer and synergy between researchers from different countries, achieving important results. Practically, researches and examples of good practise show that biogas can be a viable solution to mitigate the effects of climate change, and in the coming decades, under the conditions of the population growth estimates materialization, we will most likely witness an intensification of agriculture to ensure the population's food needs.

Sunflower is the most important oil crop practiced in Romania, in terms of the constituent indicators of the primary supply, but also by the fact that sunflower seeds have a surplus trade balance at national level. Culture has a high productive potential, it comes to exploit the existing opportunities on the market, in terms of existing opportunities nationally and internationally. Over time, Romania has been a dynamizing factor of scientific research in the field, highlighting the concerns of researchers from National Institute of Agricultural Research and Development (INCDA) Fundulea for the creation of a quality genetic material. It should be noted that the favorability of sunflower cultivation is quite pronounced at EU level, both due to the pedoclimatic conditions and due to the existing traditions in certain areas (less tradition in the extreme Southern part of the EU), for the practice of other crops providing raw materials for obtaining oil or consumption habits of the population (olive - in the Mediterranean area). The topic of this paper was approachd based on the existing global and continental context for the period 2007-2019. The results showed that in this period 2007-2019, Romania cultivated (on average) 3.81 and 5.39 of the world and European area respectively (966.84 thousand ha compared to 25,325.47 and 16,298.01 thousand ha respectively), achieved 4.62 and 6.79% of the total production (1,919.96 thousand tons compared to 41,548.57 and 28,296.81 thousand tons). The importance on the international market is highlighted by the fact that Romania held 22.52 and 26.97% of the world and continental volume of exports (1,070.99 thousand tons compared to 4,755.42 and 3,971.52 thousand tons), and for imports, the shares were 3.96 and 6.05% (183.47 thousand tons compared to 4,629.84 and 3,220.90 thousand tons respectively). Romania is not an important player in the market of this product at European and global level, especially since sunflower seeds can reduce the deficit of the external trade balance, given the appropriate use of the specific national potential.

Alfalfa is the most widely grown perennial forage legumes that are planted frequently for hay, pasture, and silage worldwide, due to its extremely nutritious forage and wide range of adaptability. High yield and economic efficiency of alfalfa (Medicago sativa L.) are important in determining the effective distribution of new cultivars to farmers. The present study was conducted to explain alfalfa yield variation induced by environmental conditions and genotype. Forage yield, aboveground phytomass, stems elongation, internodes number, growing rhythm, economic performance was assessed for a set of 10 Romanian alfalfa genotypes experienced at ARDS Caracal, Romania, in each of three years (2019-2022). Stem elongation values ranged between 131.4 cm for alfalfa line F2909-2 and 138,8 cm for alfalfa line F2910, while the average internode number ranged between 24.6 for F 2908 and 27 for F2906. Variation in stem elongation was associated with variation in the number of internodes and was positively correlated (r = 0.4448). Also, the fastest growing rhythm was observed to the genotype F2905 and the lowest to F2910. The most economic efficient and profitable was the genotypes F 2907, F2908 and F 2910. Alfalfa production offers a compelling case for both economic efficiency and sustainable agriculture.

The paper studied the impact of integrated plant nutrients management strategy (IPNM) on the agricultural return during current Syrian crisis through the application of camel manure and chemical fertilizers on the black cumin quantitatively and qualitatively. The fertilization treatments were denoted as T2 [N120-P30-K30], T3 [N120-P30-K30], T4 [5 t. ha-1 camel manure], and T5 (½ [T3 + T4]), respectively. The no-fertilizer treatment (T1) was considered as control. Soil fertility, irrigation water use efficiency (IWUE), and oil content were considered. Results have showed that organic manure(camel dung)decreased soil pH and OC/ON ratio and increased the availability of nutrients in the soil. What led the black cumin to respond by significantly increasing the following productive parameters: plant height, roots depth, number of primary and secondary branches,..etc. The treatment T5 recorded the highest IWUE values (5.2 and 6.2 kg.ha-1.mm-1) and the best oil content (33.3% and 34.2%) in the two seasons, respectively. Furthermore, the applied IPNM strategy had remarkably increased fertilization efficiency and economical feasibility (profit/ total costs) in the order of T5>T4>T3>T2 compared to T1.

The purpose of the study was to analyze the main indicators carried out in agriculture for assessing the contribution of agriculture to the economic development in Romania in the period 2013-2022 based on the data provided by National Institute of Statistics. The data were processed using fixed and structural indices, regression equations, determination coefficient, graphical illustrations and comparisons. The results highlighted that in the studied period, Romania's Gross Domestic Product (GDP) increased 2.21 times reaching Lei 1,409 Billion in 2022. Agriculture produced Lei 63.04 Billion GDP in 2022, and its contribution to Romania's GDP is 4.5%. Gross Value Added (GVA) increased 2.28 times in the economy accounting for Lei 1,282.3 Billion in 2022. Despite that GVA raised by 118.6% in agriculture, accounting for Lei 58.98 Billion in 2022, agriculture's contribution was only 4.6%. Gross Fixed Capital Formation (GFCF) raised in the economy by +131.55% accounting for Lei 377,2 Billion in 2022, but in agriculture it was very small, only Lei 2.65 Billion. Net Investment Rate (NIR) was 27.4% in 2022, but in agriculture only 4.5%. A decline by 8.7% in the number of employees was noticed in the economy, employment reaching 7,806 thousand persons in 2022, but in agriculture the reduction was 65.7% remaining only 878 thousand employees. Despite that both export and import value increased, the trade balance was a negative one, the deficit at the end of 2022 being EUR -34,101 Million. The agro-food export value raised by +126.32% and reached EUR 11,960 Million in 2022, which means that agriculture contributes by about 13% to Romania's exports, while the contribution to imports raised by +167.54%, accounting for EUR 13,248.6 Million. The deficit in the agro-food trade balance accounted for EUR -1,288.6 Million, Romania being a net importing country. Despite of its increased contribution to GDP and GVA, agriculture is facing a gap versus industry and services in GFCF and NIR. Without a better technical endowment and higher investment, agriculture cannot apply modern technologies to increase production and sustain internal market and export and to diminish imports.

The purpose of the paper was to analyse the role of public agricultural spending as a panacea for agricultural subsector production in Cameroon. The data were taken from World Bank development database and processed using growth model, and error correction model. Despite the agricultural sector's significant contributions to the country's economy throughout the years, the country has made little headway in reducing it. Recent interest in the relationship between government spending and economic output has not focused on the central question of whether government spending, particularly agricultural spending increases agricultural subsector output or otherwise. With instantaneous and compound growth rates of 6.7 percent and 6.93 percent, 3.03 percent and 3.08 percent, 13.66 percent and 14.64 percent, respectively, the results demonstrated stagnation in agricultural and livestock subsector production and labor. In contrast, public agriculture spending increased at a faster rate, with instantaneous and compound growth rates of 6.09 percent and 6.27 percent, respectively. In the short run, agricultural land, labor, and public agricultural spending all have a substantial impact on animal productivity. Cutting public agricultural spending by 25% is the most cost-effective way to maintain crop and livestock production in the short term. Incentives such as tax reductions and infrastructure development should be established to attract more private investors, knowledge transfer, and significant capital inflows to ensure the agricultural sub-long-term sector's viability. In the short term, privatization of the government's agricultural development projects will be critical for efficient use of public resources.

The paper explores the possibility of transport development as a factor for the rural integration of a population of over 100,000 using the example of the city of Stara Zagora in Bulgaria. The analysis showed that improving the access of the rural population to the agglomeration areas can be done through the combination of inter-urban transport that connects the villages with the nearby city The purpose of developing this process is to increase the access of the rural population to the cities and, accordingly, to bring out the problems that the people of the villages have in terms of urban transport. Based on a proposed methodology, we propose to highlight the main public transport problems of the rural population. On the other hand, to propose different views and models to achieve higher efficiency of urban transport and its implementation in rural areas. In this paper, quantitative and qualitative analysis is used and the results are also used to assess the impact of price fluctuations on vegetable marketing channels including vegetable processing enterprises. Data on vegetable prices were extracted from the tempo on line database and the analysis was also based on interviews with key stakeholders in the vegetable processing chain. The results reveal a high coefficient of variation at the farm gate stage, which is also transmitted to the distribution and commercialization stage. The analysis was also carried out at the processing level and the results also show a rather high coefficient of variation.
