Short supply chains are a new approach to agricultural marketing, responding to the challenges posed by globalization and the complexity of traditional supply chains, and changing the way agrarian producers market their products and interact with consumers. This article explores the impact of short supply chains on agricultural marketing, and the results of the study show that these short supply chains bring numerous benefits. These include increased transparency, reduced costs, and strengthened relationships between producers and consumers. The study highlights that, through short chains, the efficiency of the marketing process is improved, and the actors involved benefit from better collaboration and mutual trust. The research presents a case study to highlight the trends and potential of this model in agricultural marketing. The findings highlight the need for a wider integration of short supply chains in agrarian marketing strategies, but also for improving the sustainability and resilience of farming systems.

Thermal analysis during frying operations depends on the types of materials, the pans, and the quality of the oil used. Continuous exposure to changing temperatures changes the specifications. The experiment was planned to study the thermal analyse with various pan materials properties and repeated oil frying. The pan was tested and oil frying under steady-state heating conditions. The infrared images extracted with MATLAB, and testo software also Solid Works software were used to determine the material's convection coefficient, and specific heat,. The temperature rise at each point through surface and volume parameters from 0 to 8 minutes at three frying stage of oil and each skillet. The results showing as the frying temperature begins to rise, it rises with heat transfer rate (convective) reached 1,435.32 J/Kg·K during the third stage at 8 minutes. The specific heat capacity peaked at 1,191.37 J/Kg·K during the first stage at 6 minutes. Conversely, the minimum values for these indices were 522.90°C, 1,322.35 J/Kg·K, and 1,006.89 J/Kg·K, observed during the second stage at the beginning, specifically for the wok skillet.

Environmental and anthropogenic factors, especially agricultural practices, generate a series of changes on the soil physico-chemical and biological indices. The periodic determination of quality indices is important to know the level of soil fertility, and the application of appropriate measures for crop yield. The present study analyzed the agrochemical indices of soil quality, and used multiparameter analysis (PCA) to obtain the loading of the indices on the main components, the mode of action, and the intensity of each soil index. PC1 comprised soil pH (r = -0.923), B (r = -0.883), Fe (r = 0.782), CaO (r = -0.777), NH4 (r = 0.752), K2O (r = 0.545), and Mn (r = 0.286). PC2 included Zn (r = 0.873), P2O2=5 (r = 0.786), Cu (r = 0.756), and S (r = 0.316). PC3 included Nmin (r = 0.960), and NO2=3 (r = 0.950). PC4 included MgO (r = 0.888), and Na2O (r = 0.881). In relation to the soil reaction, the 38 soil trials were classified into three categories, acid reaction (11 trials), neutral reaction (7 trials), and basic (alkaline) reaction (20 trials). Based on the PCA, the three groups were positioned differently, with an independent position in the case of the acid reaction, and with an overlap in the case of the neutral and basic reaction, as transition zones.

The study analyzed the spatial variability of the autumn wheat crop, based on remote sensing techniques. The RapidEye satellite system was used to retrieve images of the wheat crop. The images were taken during May, when the vegetation was already well represented in relation to the vegetation conditions. Based on the images, the NDVI index was calculated. The map of the NDVI index was reclassified and six classes resulted (C1 to C6). The NDVI raster image was transformed into vector format and the area (Area, ha) was calculated for each class. The area per class varied between 1.873 ha (3.81%) in the case of C1, and 12.659 ha (25.78%) in the case of C4. There were significant differences between sample medians of NDVI on the six identified classes, H (chi2) = 1.877E04, Hc (tie corrected) = 1.877E04, p = 0. According to the t Test and the Wilcoxon Test, there were significant differences (sig. diff.) between the data series C1 to C6 of the NDVI index, and the mean value, respectively the median, at the wheat crop level. The Area variation in relation to NDVI was described by a 3rd degree polynomial model (R2 = 0.999, p = 0.00104). The spatial distribution of NDVI values was most likely associated with fertilization works, which generated certain non-uniformity in the distribution of fertilizers.

The sustainable management of endogenous resources is a complex and current theme of global interest that promotes a territorial diagnosis model to highlight the specificity of the studied area and develop relevant strategic options for the development of the rural economy. The actuality of the research has a counterpart in the requirement of the development of the rural economy by the achievement of the modernization criteria and the preservation of the natural and anthropic heritage, and the complexity is highlighted by the orientation towards innovation in the sense of the adoption and implementation of technologies with low impact on the environment. Specifically, the research aims at the strategic diagnosis of Vaideeni commune in order to identify the endogenous resources and developing relevant strategies for their sustainable exploitation. Vaideeni commune is located in Vâlcea county and represents a remarkable area recently declared a tourist resort of local interest, rich in traditions and customs preserved unaltered. For the strategic diagnosis, the PESTEL model was used, the usefulness of which is recognized, because it allows highlighting the particular aspects of the studied community. The results of the PESTEL model allow the adoption of relevant measures to correct the rural economy and improve its resistance to the increasingly frequent changes occurring in the environment. Next, the SWOT analysis was used, doubled by the realization of a focus group with key local factors and specialists, concerned with the development of the rural economy. The general conclusion derived from the results obtained when applying the PESTEL and SWOT analysis models highlights that the sustainable development of the rural economy is closely related to the territorial specificity and is supported by the community that gives life to and maintains the territory that belongs to it.

In recent years, the meat processing sector in Romania has experienced rapid development, at the level of all existing regions. This was possible thanks to access to non-reimbursable European funds. It can be said that following the investments made, this sector has developed, resulting in a modern meat processing industry, where there is a permanent concern for food safety and quality. The present study was carried out to highlight the evolution of the production capacities of meat processors who accessed non-reimbursable funds in the South-West Oltenia Development Region. Investment value, processing capacity and the profit from the project set up by meat processing companies operatinng in teh region swere used to determine the investment efficiency in terms of specific invetment, investment pay back and coefficient of economic investment. In this region, between 2016 and 2020, 4 projects were financed, where the total increase in meat processing capacity, through the contribution of the National Rural Development Program, was 15,884 tons/year.

The yield of hard cheese depends on the amount and ratio of milk components. Moreover, the yield of cottage cheese is significantly influenced by genetic variants of milk protein and other genes. The goal of this study is to examine the effect of variants A and B of beta-lactoglobulin and variants A and B of the PIT1 gene on cheese yield and its individual qualitative indicators. It has been found that the genotype of cows based on the beta-lactoglobulin gene affects the yield of cheese produced from their milk. The highest yield is obtained from milk of animals with the BB genotype. At the same time, a higher content of essential amino acids is characteristic of cheese made from milk obtained from animals with the AA genotype by beta-lactoglobulin. The PIT1 genotype has also affected the yield of cheese made from milk. Cheese samples made from milk of heterozygous animals (AB) have the best average values. The amount of essential amino acids in cheese prevails in samples made from milk of homozygous (BB) cows. Forming herds with the desired genotypes based on the studied genes for cheese production requires establishing contractual relations between milk producers and milk processing plants.

Fertility and soil balance cannot be maintained without the presence of organic matter and the addition of new quantities of plant residues or chemical and organic fertilizers, as plants extract significant amounts of nutrients from the soil each year. Therefore, the application of manure can be considered a good source for increasing the potential fertility of the soil. This study addresses on the fertilization with manure derived from cattle and sheep farming activities on the typical chernozem soil from the Romanian Plain. The effects of using these organic fertilizers are mainly observed in the behavior of nitrogen (N) and phosphorus (P) in the soil, as they are the main nutrients that influence agricultural crop yields. Potassium (K) has a secondary role, but along with pH and other macronutrients, it improves the physical and biological properties of the soil, as evidenced by the appearance and formation of a positive humus balance and an improvement in the NPK content of the soil. Following the application of manure over a period of more than five years, changes in the physical-chemical indicators are observed, such as the bulk density of soil which decreases from 1.28 g/cm3 to 1.17 g/cm3, or the humus that increases from 2.07 % to 2.57 %, after five years of manure action.

The wine sector has a significant importance in the economy of the European Union, contributing to the increase of exports, the preservation of traditions and the generation of jobs in rural regions. Romania, recognized for its wine-growing tradition, ranks sixth in Europe in terms of wine-growing area and benefits from considerable support through the Common Agricultural Policy (CAP). The paper analyzes the support and protection measures of the Romanian wine sector within the rural development programs of the two programming periods, 2007-2013 and 2014-2020, which Romania went through after joining the European Union. The allocated funds supported the restructuring and reconversion of the vineyards, the modernization of the viticultural infrastructure and the promotion of exports. At the same time, measures were implemented to adapt to climate change and improve sustainability. In conclusion, it emphasises the need to continue European support for maintaining the competitiveness of Romanian wine on international markets, considering the climate challenges and global competition.
