This study aimed to compare the economic aspects of greenhouse tomato production under agroecological and conventional conditions in Antalya province, which ranks first in tomato production in Türkiye. The main material of this study was collected from questionnaires compiled by face-to-face interviews with 80 producers following either agroecological or conventional management for tomato production under greenhouse conditions. According to the results of the research, the average farm size was 3.97 ha, with 2.68 ha devoted to tomato production area on 5.8 parcels in agroecological farms and 1.55 ha, 1.11 ha and 4.49 parcels in conventional farms, respectively. Total production costs per hectare resulted 68,840.80€ in agroecological farms and 59,744.67€ in conventional ones. Gross production value per hectare was 139,625.34€ in agroecological production and 87,707.84€ in conventional one. Net profit was 70,784.55 €/ha and 27,963.17 €/ha for agroecological and conventional production, respectively. Profit margin resulted 0.34 and 0.18 €/kg in agroecological and conventional production, respectively. The ratio of profit margin to sales price was 50% in agroecological production and 31.83% in conventional one. In terms of profitability indicators, agroecological production was found to be more advantageous than conventional one due to a higher production value resulting from higher yield and tomato selling price.

The paper aimed to analyze the economic and technical efficiency of the spray irrigation system for maize, barley and wheat cultivated in the North-East part of Romania. In order to obtain stable and marketable products, it is necessary to optimize the amount of water indispensable for plant growth and fruiting, even when there is no water from natural precipitation or when plants cannot grow due to a lack of groundwater. In the North-East Region of Romania, by using local water sources and implementing modern irrigation techniques, it is possible to fully satisfy the water needs of plants, contributing to the improvement of irrigation efficiency. Thus, a profitable, sustainable and environmentally friendly agriculture can be achieved. The main production costs for the agricultural year 2022-2023 were about 4,000 lei for the non-irrigated maize crop and about 5,000 lei in the case of irrigation systems. For the production of wheat, increases of cca. 1,000 lei were recorded for the irrigated crop, compared to the non-irrigated one, similarly recorded in the case of the barley crop. This is mainly due to the increase in the cost of inputs price, the increase of water price and the fuel used for irrigation electricity generators. On average, the results obtained for the three investigated crops show that grain corn produces a higher profit per hectare when it is cultivated in an irrigated system (10,600 lei/ha) than when it is cultivated in a non-irrigated system (4,400 lei/ha). For the wheat crop, a profit of 3,500 lei/ha was recorded in the irrigated regime compared to the crop in the non-irrigated regime, where the profit was 20 lei/ha. Moreover, in the case of barley, a profit of 5,480 lei/ha was recorded in the irrigated system compared to the non-irrigated one.

The focus of this study is to evaluate the effects of fixed capital investments, credit availability, and net entrepreneurial income on the gross value added of Bulgaria's agricultural sector during the years 2004 to 2022. The primary goal of this research is to investigate the development of gross value added in Bulgaria's agriculture, focusing on the effects of fixed asset investments, the influence of agricultural sector financing and the relevance of net entrepreneurial income. This investigation involved the creation and testing of three distinct hypotheses. Multiple regression analysis is utilized to explore how the sector's gross value added, investment activities, credit resources, and entrepreneurial income are interrelated in terms of both direction and strength. Data from Eurostat, FAOSTAT, and the Bulgarian National Bank (BNB) are used for the study. The results allow us to conclude that these three indicators strongly correlate with gross value added and explain a significant part of its dynamics. It has been established that investments in fixed capital in agriculture and net entrepreneurial income have a strong positive impact on gross value-added growth. A positive effect has also been demonstrated regarding credit but with statistical significance at a higher confidence interval. As a result, the study suggests broadening the range of financial tools available for agricultural lending, encouraging capital investment in agriculture, implementing tax relief measures, and easing administrative procedures for small and medium-sized enterprises to foster entrepreneurship. Collectively, these actions would support the sustainable growth of the agricultural sector while improving its productivity and global competitiveness.

The study aimed to assess the impact of additional milk replacer feeding in the first week after weaning on growth, survival, feed efficiency, and economic indicators of piglets' growth. The reduction of weaning age and high multiparity of modern sows cause stratification of piglet litter by weight. This reduces their adaptability to housing and feeding conditions during growth. The inclusion of 130 g of liquid milk replacer per day in the first week after weaning provided 27.4% weight gain, 21.1% weight gain at the time of transfer to fattening, 10.3% improvement in feed conversion, 21.1% increase in piglet market value and 12.2% increase in profitability. At the same time, there was a 3.0% decrease in the cost of feed per 1 kg of gain, a 13.1% reduction in treatment costs, a 3.1% decrease in the price of 1 kg of gain, which contributed to a 2.7% increase in profitability and 6.9% higher profitability. Along with the positive results, a 13.9% increase in daily feed consumption, a 23.1% increase in its cost, 10.3% higher treatment costs, a 23.0% increase in the price of growing a piglet, and a 4.1% lower profitability of growing a piglet was recorded. Therefore, using milk replacer improves piglet productivity but requires additional costs to be considered.

The study aimed to assess the economic efficiency in pig fattening using a new feed ration based on a low-digestible protein and adding the amino acid supplement AminoPro. For this purpose, the experiment included different levels and degrees of protein digestibility in diets supplemented with amino acids. In this way, it was possible to evaluate the fattening qualities of hybrid pigs. The experiment was conducted at the "Ryabushkivsky Bacon" pig complex in the Sumy region with F1 hybrid pigs (VBxL sows x PIC-337 boars). Six groups of 20 pigs, divided by live weight and sex, were fed diets with varying protein digestibility. After a 30-day equalization period, five pigs with extreme weight gains were excluded, leaving 15 animals per group. Over 16 days, pigs were fed either quickly or poorly digestible protein diets with the AminoPro supplement. Dry compound feed was used throughout the experiment. Lightweight piglets on conventional diets with easily digestible protein achieved a final weight of 2.10 kg (1.56%) higher than those with AminoPro. Medium-weight pigs on conventional diets outperformed the experimental group by 2.60 kg (1.84%). Absolute weight gain in pigs fed AminoPro diets was 4.60 kg (6.03%) higher than those on conventional diets. Average daily gains increased by 53 g (6.04%) in medium-weight pigs consuming AminoPro. Feed conversion rations improved in lightweight pigs on conventional diets by 0.07 kg per gain, while medium-weight pigs on AminoPro consumed 0.27 kg less feed per kg of gain. Pigs fed AminoPro diets demonstrated higher fattening quality indices across all weight groups, with significant correlations between initial and final weights. The findings provide valuable insights for optimizing feeding strategies, improving growth performance, and reducing feed costs, contributing to greater profitability in pig production.

The paper aimed to assess the economic efficiency in sows reproduction using artificial insemination in industrial production conditions. For this purpose, the post-cervical method was used to inseminate the sows, and this proved to be the most efficient method compared to other insemination methods. The results showed a tendency to increase the farrowing rate by 0.68% in sows in which semen was introduced by the post-cervical method. There was also a tendency to increase the total number of piglets born in sows using the intravaginal insemination method. At the same time, no difference in multiparity was found between sows inseminated with different methods. It was found that due to the improvement of artificial insemination techniques and the introduction of the post-cervical method, the number of doses of semen required to inseminate a sow per year decreased by -13.0%, the volume of a dose of semen decreased by 44.4% and the total amount of semen decreased by 51.7%. The total amount of semen used to inseminate a sow per year decreased by 7, which proportionally reduced the cost of inseminating the entire breeding herd, the amount and cost of semen diluent, main catheters and semen disinfectant used decreased by 13.0% and the number of boars decreased by 44.0.

Forage production from mixed grasslands is closely related to their productivity and quality. In this context, the correct selection of components in grass mixtures ensuring an environmentally acceptable grass association is essential, linked to the realization of cost-effective grass forage under sustainable management of natural resources. The object of the analysis is the characteristics of the main economic indicators in a scientific research experiment involving the following grass species: bird's foot trefoil + cock's foot; bird's foot trefoil and red fescue; bird's foot trefoil+ timothy; bird's foot trefoil + cock's foot + red fescue + timothy. The agrotechnical measures used and the costs involved are relevant to the amount of gross income, cost and profit of forage production. The high economic efficiency of the mixture of bird's foot trefoil + red fescue (82.65%) makes it the most suitable for hay in mountain regions. The realized forage production from it has the lowest production costs (19.57 BGN/da) and the lowest cost (0.018 BGN/kg). The high coefficient of economic efficiency makes it extremely profitable and suitable for practical application.

This research aims to comparatively analyze the economic resilience of the European Union member states, in the context of successive economic shocks, by constructing composite scores that synthesize the adaptation and recovery capacity of each economy. The main goal was to highlight the structural and dynamic differences between economies, in terms of internal stability and response to crises, thus providing an integrated tool for evaluating and substantiating public policies. The objectives pursued included: (1) measuring structural resilience in the pre-crisis period, 2015–2019, (2) assessing post-shock resilience in the period 2020–2024, (3) comparing performances through standardized scores and (4) identifying the determinants of economic resilience in the EU. To achieve these objectives, a quantitative methodology was used, based on the aggregation and standardization of four main indicators: GDP per capita, unemployment rate, annual inflation (HICP) and total exports, with data from official sources (Eurostat) for all 27 EU Member States. The results show clear differences between economies, both in terms of structural fundamentals and post-crisis adjustment capacity. Germany, Ireland and the Netherlands stand out with high overall scores, while Greece, Spain and Estonia are at the bottom of the ranking, indicating persistent vulnerabilities or recent heightened pressures. Romania is in a middle position, with a balanced profile, but with clear needs for institutional consolidation and macroeconomic stability. The proposed scores provide a synthetic picture of resilience and can contribute to guiding development strategies and the efficient allocation of European resources.
