The increasing use of pesticides in modern agriculture has led to increased concerns about the risk of pollution of surface waters, soil and its agro-productive properties. The application of large doses of pesticides using outdated technologies and non-performing agricultural equipments, with poor application in terms of distribution uniformity and the lack of farmers’ knowledge and measures to prevent the drift phenomenon leads to their spread outside the targeted areas and implicitly to the increase of environmental pollution. In the present study, three anti-drift agents: EM260 (dodecilbenzensulfonat of calcium 50%, and butanol 18%), SC (heptametiltrisiloxan polietilenglicol) and respectively SO (surfactant non – ionic) have been tested according to ISO 22866, in the field conditions of Agricultural Research Development Station (ARDS) Caracal, Romania. The obtained results emphasized that the most valuable, among all variants, was EM260 (dodecilbenzensulfonat of calcium 50%, and butanol 18%) with smaller drift effect recorded at 1 meter distance (6.4%), followed by the second point, at 3 meters (3.1%) and at 5 meters with a calculated value of 2.1%. Also, at this variant the affected plants percent was smallest from the entire tested assortment, of 35.2%.

The article shows the productivity of piglets when they were fed from day 42 to day 70 of this period with sunflower meal (SP-45) instead of soybean meal (SP-48). The manuscript highlights the effectiveness of replacing soybean meal with high-protein sunflower meal in the final period of rearing pigs. It was established that this change in the diet of piglets during their rearing period contributed to a 1.0% improvement in the survival of piglets during the experiment, at the same time it led to a 7.6% decrease in daily feed consumption, which caused a 9.7% deterioration in the intensity of animal growth and as a result of a 6.8% decrease in live weight of piglets at the end of rearing and a 2.3% decrease in feed conversion. The replacement of soybean meal with high-protein sunflower meal in the structure of the starter feed made it possible to reduce its cost by 4.7%, which made it possible to reduce the cost of 1 kg of growth by 2.4%, and the cost of growing 1 head before transfer to fattening by 8.2%. At the same time, in the group of pigs consuming sunflower meal due to a decrease in their productivity and a decrease in their final weight, as a result, the market value of one piglet before transferring them to fattening decreased by 5.9% and the income per 1 reared head decreased by 1.7%. Whereas in the group of piglets that used sunflower meal instead of soybean meal in the starter feed recipe, the profitability of raising piglets was 3.89% higher.

The variation of some parameters of flowering, fruiting, and pepper production, in relation to the fertilization system, was evaluated. The study took place in the area of Cuied Locality, Arad County, Romania. The experiment was in a protected system, modular solar, the summer-autumn crop cycle, year 2020, with a specific technology. Two long pepper varieties of the Kapia type were cultivated (Dumbo 34 - D 34; Elephant's Ear - EE). Three products were used for fertilization, BioHumusSol (BHS), Cropmax (CroM) and Bionat (BioN), together with a control variant (C). The number of pollinated and fertilized flowers per plant (pff) varied between 5.00±0.35 (EE C) and 8.60±0.41 (D34 CroM), and the number of fruits per plant (FruNP) varied between 5.00±0.32 (EE C) and 8.00±0.49 (D34 CroM). The average fruit weight (FaW) varied between 83±13.30 g (D34 C) and 274±22.7 g (EE CroM). The average fruit production per plant (ApP) varied between 0.580±0.13 kg plant-1 (D34 C) and 1.920±0.20 g plant-1 (EE CroM). Quality I production (YQ1, %) varied between 10.20% (S34 C) and 76.00% (EE CroM), and quality II production (YQ2, %) varied between 24.00% (EE CroM) and 89.80% (D34 C). According to PCA, PC1 explained 68.383% of variance, and PC2 explained 28.917% of variance in relation to flowering and fruiting parameters; PC1 explained 65.489% of variance, and PC2 explained 34.28% of variance in relation to productivity and production parameters, respectively PC1 explained 61.09% of variance, and PC2 explained 38.91% of variance in relation to production quality. The regression analysis facilitated to describe the variation of production by quality classes (YQ1) in relation to productivity parameters.

In a society dominated by an ever-evolving transport sector and experiencing profound technological change in all areas, we cannot deny the impact of transport on the environment. This paper has examined the main environmental impacts of transport activities associated with the food sector in order to undertake a critical review of the challenges we may face in developing this sector. The main objective was to show the links between transport activities throughout the food life cycle and the environment. The paper reviewed the main studies in the field and the results identified the main ways in which transport affects the environment and identified some solutions to reduce its impact. The materials used in the research cover a wide range of information on the environmental impacts of transportation activities. Available scientific literature containing information on transportation was used, and the scientific material was analyzed theoretically. Our brief review of the environmental impacts of transportation activities related to agriculture showed that greenhouse gas emissions in this sector are increasing. Our research has shown that it is necessary to use efficient vehicles, reduce transport distances, develop cooperation in transport networks, use new types of packaging, etc.

This investigation has been conducted to determine the fluctuations in the real prices of melon, watermelon, and grapes cause volatility in their own and other markets in Turkey. Diagonal-Bekk Garch (1,1) model was used under the Full-rank constraint with 101 monthly data for the period 2010M01-2022M08. The results of the research have put out that the shock or uncertainty experienced in the melon and watermelon market has increased the uncertainty both in its own market and in the watermelon and grape markets. Shocks in the grape market have only increased the uncertainties in its own market. In addition, it has been determined that the shocks in the melon and watermelon markets are permanent in these markets in the short and long term, but the shocks in the grape market do not have a permanent effect in the short and long term. As a result, it may be necessary to reduce the negative effects of this situation on consumers and to regulate and renew policies that will minimize the risk for producers and consumers in the face of high price volatility.

The study evaluated the vegetative propagation of geraniums, Pelargonium peltatum, under the influence of some bioactive substances. 10 products with biostimulatory effect were tested, along with a control variant: V1 (control, water treatment), V2 (Radifarm, 0.2%), V3 (Radistim, powder - cuttings treatment at planting), V4 (Ecopan-1, 1.5%), V5 (Legume extract 1, 1.5%), V6 (Aromatic plant extract, 1.5%), V7 (Legume extract 2, 1.5%), V8 (Ecopan-2, 1.5%), V9 (Bionat Plus, 1.5%), V10 (Dill Essential oil, 1/50), V11 (GMO Essential oil, 1/100). The uniform geranium cuttings, 10 cm long, and with a pair of leaves at the top, were placed on a peat-based rooting substrate. The rooting process was evaluated in terms of the roots number (RN) and the roots length (RL). The planting took place on February 20, and the determinations were made on March 6 (T1), March 13 (T2), March 20 (T3) and April 2 (T4). The variants V2 and V3 were highlighted, as roots number (RNV2=18.5±1.21, respectively RNV3= 11.5±1.21), and variants V10 and V6 as root length (RLV10=17.20±0.20 cm, respectively RLV6=16.10±0.20 cm). Strong, positive correlations were identified between RN-T3 and RN-T2 (r=0.795**), between RL-T3 and RL-T2 (r=0.801**), and between RN-T4 and RN-T3 (r=0.756**), in statistical safety conditions (** p<0.01). Based on PCA, PC1 confirmed 42.128% of variance, and PC2 confirmed 33.487% of variance. The values of the parameters RN and RL at the T4 moment (considered the end of the rooting process) were evaluated in relation to intermediate values (T2, T3) by regression analysis and equations were obtained in statistical safety conditions (R2 = 0.992 for RN, respectively R2 = 0.981 for RL, p <0.001 in both cases).

Rural tourism provides an environment where rural people meet different cultures, prevents immigration to already crowded city centers, becomes an element of rural development, creates income diversity and protects the environment as well as natural, cultural and historical aspects of regions. The aim of this study is to examine effects of COVID-19 pandemic on rural tourism-potential and rural planning using Cizre District, Turkey, which incorporates distinct geographical, cultural and historical elements in a rural environment. Data were collected using primary and secondary sources in the region. SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis was used to analyze data which shows an increase in migration to rural causing environmental pollution. Positive effects include increase in commerce and housing demand strengthening the economy following normalization. Findings should help to review and improve sustainable planning and policy strategies supporting new economical environment in rural. The development strategies need to focus on rural and urban being partners rather than rivals.

Genotyping of 47 stud bulls of Brown breeds was carried out by the gene CSN3. The results of scientific studies indicate that both Brown purebred and cross-breed cattle bred in Ukraine are characterized by a significant difference in the frequency of genotypes by this trait. The genetic equilibrium established by us corresponds to the global trends of breed populations. The creation of the desired micro-populations with the desired homozygous BB genotype by kappa-casein makes it possible to improve the quality of milk as a raw material for milk processing enterprises specialized in cheese making. Therefore, the increased frequency of the BB genotype by kappa-casein may contribute to the preservation and distribution of Brown cattle in Ukrainian farms.

In recent decades. rural areas have been facing numerous problems. such as an ageing population. lack of jobs, migration of young people, poor infrastructure which negatively affect the quality of life of rural inhabitants. The aim of the study is to observe the economic and social evolution of the Romanian countryside over the last 10 years, taking into account the disruptive phenomena that have occurred during this period. The study is based on a quantitative and qualitative analysis of data provided by the National Institute of Statistics. In both urban and rural areas, the population tends to decline. In the case of the urban population. there was a 4.09% decrease over the period analyse, from 10.9 million to 10.46 million inhabitants. In contrast, the rural population decreased by 4.57% during the period, from 9.3 million to 8.87 million. Among the main reasons for this decrease, we can mention the high mortality rate (high degree of ageing). but also the migration of the population to Western European countries. a phenomenon that was accentuated with Romania's accession to the European Union in 2007.
