Bulgarian agriculture is traditional and very important for developing rural areas. Over the years, the agricultural sector has been transformed by processes and policies that affect its changes. The Common agricultural policy significantly facilitates the transformation of Bulgarian agriculture regarding farm development and redistribution of activities. In this regard, the article aims to track the development of the main agrarian structures in Bulgaria from 2010 to 2020. The materials provide the most recent statistical data for the analytical period, during which we examined the evolution of Bulgaria's main agricultural systems. We used regional-level indicators such as farm numbers, utilized agricultural areas, farms by economic size classes, standard output by economic size classes, and farm specialization. The study takes into account production volume discrepancies between regions and the Country. The South-Eastern region has the most significant economic contribution, producing more than EUR 250,000 Standard Output while having the fewest farms. Conversely, the South-West and South-Central areas have the lowest economic share, making less than EUR 2,000 Standard Output while having the most farms. This zoning presents a complete picture of farm economic conditions, which impacts agricultural growth in Bulgarian rural areas. Finally, regarding GDP distribution in key economic centers and mechanical movement, Sofia (the Capital), Plovdiv, Varna, Burgas, and Kardzhali show the most significant contrasts.

Uncleaned and ungraded onions stored in sacks command low prices, a significant share of farmers' income. Manual cleaning and grading of stored onions are labor intensive, tedious, and provide inconsistent results. This study sought to develop a dry-scale cleaner cum grader for stored onion bulbs to simplify operations, reduce labor costs, minimize operation losses, and generate more income for the onion farmers. The design of the machine parts was computed based on the onions' average physical (shape, size, surface area, density, colour, and weight) and mechanical (hardness, compressive strength, impact, and shear resistance) properties. The study used locally available materials to fabricate the machine and conducted a preliminary performance test to ensure functionality and optimum machine speed settings. Based on the results, machine cleaning and grading speed of 71 rpm and 17 rpm can remove dry scales and grade them according to standard sizes at a rate of 493 kg/hr at 73 % efficiency. The machine reduced manual labor utilization from 3 man-day/100kg to 0.08 man-machine-day/100kg. Mechanical damage (2%), including slight bruises in the bulbs, and the noise level (82 dB) were lower than the maximum threshold of 3% and 92 db. The machine costs ₱125,000 with an operating cost of ₱40/100kg and power consumption of 14.41W-hr. It can break even after cleaning and grading 33,263 kg of stored onion bulbs at a custom rate of ₱1/kg per year. The study successfully developed the onion cleaning cum grading machine suggesting group ownership for utilization.

The advent of Industry 4.0, marked by the integration of cyber-physical systems, the Internet of Things (IoT), and advanced data analytics, is revolutionizing the logistics industry. The paper proposes to use a survey developed and provided by the Research group Logistics and Alliances of the HAN University of Applied Sciences (the Netherlands). The survey was edited in March and April of 2023 and used from April 2023 to February 2024. Participants were from six partners in Europe (Finland, Spain, Ireland, Croatia, Romania, Austria) and one in Argentina. Students from all partnering universities interviewed their chosen case companies. The questions were categorized in the next sections: Background questions; Organization questions; Competencies; Tools and applications; Ranking; Company’s performance compared to others. Results shows that the digitalization process in companies has started, with significant improvements in companies profit and customer satisfaction. From an organizational point of view, about 10% of companies consider themselves "Analytics as a business vision" and 20-25% are in the "data-driven organization" phase. Excel remains the most used tool for data processing, but there are preparations for integrated ERP applications in the digital management of companies. The results of the study are also confirmed by other analyses carried out by other institutions such as the Digital Maturity Assessment (DMA) tool of the European Digital Innovation Hubs Network, KPMG or BDC, and underlines the opportunity and importance of integrated digitization efforts of companies, as well as the need for standardized applications both in the field of local data processing and in international logistics chains.

In the international food market at the global level, one of the major task and strategic goal of any country is to sustain technologically and financially food security. The goal of this research work is to quantify the reserves for increasing agricultural production and to set up the directions for its sustainability. The study emphasized the opinions of foreign and Russian scientists who were dealing with the sustainability of rural areas. The dynamics of the pace of agricultural development in leading foreign countries is empirically studied, and the trends in innovative development are substantiated. The directions for sustainable growth of production potential are improved taking into account environmental factors: development of innovation and investment mechanisms to stimulate the introduction of digital technologies in agricultural production, development of scientific and educational centers to build up digital competencies, formation of a system of package solutions ready for implementation in agricultural production of digital technologies. For evaluating the efficiency of the presented activities, there were used specific indicators. The criteria reflecting the efficiency of the implementation of digital technologies regard the degree of their distribution, the increase of crop yields, the reduction and optimization of the production costs related to farm inputs. The practical value of the results is in the development of a strategy for sustainable development of rural areas.

Fruits are beneficial to humans in many ways. They are an essential part of a varied, healthful diet as well as a crucial one. As we know, fruits are seasonal food, and to guarantee longer-term storage and consumption throughout the year, they should be treated differently. The study evaluates economic indicators of three plum cultivars: Stanley, Top Taste, and Top 2000. They were dried using four different methods: in sun, in shade, in dehydrator, in lyophilizer. The study's methodological framework includes: a theoretical overview of plum drying methods, and an analysis of the economic indicators of prune fruits, such as gross production, net income, and profitability rate. The results show that freeze-dried plums have better indicators than the other three drying methods. However, if the freeze-drying method is excluded because the production price is ten times higher than that of sun-dried, shade-dried, and dried-in dehydrator plums, then in that case, the dehydration method shows better economic indicators than the remaining three drying methods at the three cultivars.

According to the greening index, the zero level of fertilization in crop rotation corresponds to biological agriculture, the first level to ecological agriculture, and the second and third levels to its biologisation. According to the ecological classification of cropping systems, the first and second levels of fertilization ensure an increasing, and the third intensive level of greening of the agricultural sector. The yield of crops in the crop rotation is significantly reduced in the case of chisel disc and disking tillage. Differentiated tillage slightly reduces this indicator in peas, corn, white mustard in the link with legumes and slightly increases in winter wheat and buckwheat. At the same time, the yield of white mustard increases in the link with buckwheat, but only in fertilized areas. In terms of crop rotation productivity, the mouldboard and differentiated tillage are equivalent, while the chisel disc and disking tillage are significantly inferior to the control. The highest indicators of economic and energy efficiency were obtained with differentiated tillage with the application of 6 tons of manure + N98P66K92 per hectare of crop rotation. It is recommended that in a five-field grain crop rotation, ploughing (mouldboard) should be carried out only for corn (to a depth of 25-27 cm), differentiated tillage for peas (to a depth of 18-20 cm), and disking tillage should be used for other crops (to a depth of 6-12 cm) with the application of 6 tons of manure +N98P66K92 per hectare of arable land and the use of non- marketable products as organic fertilizer.

As part of the study, the methodological toolkit for the functioning of land relations is substantiated. Using the software product STELLA, a system analysis was conducted to forecast trends in the development of indicators of agricultural enterprises. The gross output of agricultural enterprises was selected as an effective indicator, and the size of land plots was one of the influencing factors. It has been proven that forecasting is an important direction in the development of land relations in agricultural enterprises in modern competitive conditions. On the basis of the system analysis, modeling was carried out using the STELLA software product. The forecast of the production of gross agricultural products by enterprises of the Ivano-Frankivsk region until 2030 was carried out. The study shows, that among the main factors affecting the dynamic of the production of the gross products by agricultural enterprises according to its volume, the amount of mineral fertilizers applied per 1 hectare of land, the number of employees in enterprises and the number of animals in conditional expression are singled out.

The study was conducted in 2017–2019 at the experimental field of the Institute of Irrigated Agriculture of NAAS (now the Institute of Climate-Smart Agriculture of the National Academy of Agrarian Sciences of Ukraine).Based on the results of the economic analysis of winter wheat field trials, it has been established that varieties, sowing dates, and plant protection applications significantly influence the indicators of economic efficiency in winter wheat cultivation. The conditional net profit under natural moisture increased to 11,000 UAH/ha with the variety Maria sown in the first term (September 20) and the application of chemical plant protection. The maximum level of profitability (157%) was achieved with the variety Kohana sown in the third term and adhering to a biological plant protection system. The highest conditional net profit (14,800 UAH/ha) and profitability level (103.3%) were obtained by cultivating winter wheat with irrigation, sown on September 15, and using chemical plant protection. The most profitable results (11,000-11,100 UAH/ha) were obtained with the Ovidiy variety using integrated and chemical plant protection methods. The highest profitability level (75.8%) was achieved with the Ovidiy variety using plant protection involving chemical products. Additionally, high profitability at 71.7% was achieved with this variety using integrated plant protection.

The effect of the application of biostimulants in agricultural crops has not been fully studied and evaluated from an economic aspect. The purpose of the research is to assess the economic efficiency of the application of biostimulants in the organic production of spring rapeseed and oats. 2-year field trials were conducted using a block method with foliar treatment with Chitosan, Vermicomposting and nature-identical growth regulator in 2 phenological stages. The biological response of the crops at different doses of the biostimulants was investigated. The obtained primary results were used as input data for the construction of an economic-mathematical model for economic evaluation. In a methodological aspect, linear modeling is applied in order to optimize the production structure of a selected agricultural holding. It is concluded that biostimulants have a positive effect on yield and biometrics of treated crops, but the complex economic effect on farm profit is organic.
