Soil degradation and climate change are the most destructive (human- and/or naturally induced) processes, making agricultural production more challenging than ever before. Traditional tillage methods, characterized by intensive mechanical soil disturbance (dominantly using a plow), have come under question for their role in exacerbating soil erosion, depleting organic matter, and contributing to the decline in soil biodiversity and other soil devastating processes. These practices, while effective in the short term for crop production, undermine the sustainability of agricultural systems, posing a threat to food security and environmental stability. This review examines the adoption and implementation of Conservation Soil Tillage (CST) across six European countries: Croatia, Serbia, Hungary, Slovakia, Czech Republic, and Poland. The main objective is to analyze the historical development, current status, and future prospects of CST in these countries, highlighting the challenges and opportunities in transitioning from conventional tillage methods. Conservation Soil Tillage (CST) emerges as a promising alternative platform to still dominant conventional plowing tillage approach. By reducing the intensity and frequency of tillage, CST practices aim to maintain adequate soil cover, minimize erosion, and encourage biological activity and organic matter accumulation, thus, ensuring soil productivity and resilience against additional degradation and climate variation. Efforts made by scientists and the government to go over it sometimes are not sufficient. Farmers’ expectations of benefits are the final keystone for the integration of CST as a dominant sustainable practice. Analyses from six European countries pointed to a high level of diversity in readiness and willingness to accept, as well as different levels of knowledge about the adoption of CST. Our study suggested that the adoption of CST is increasing, and it represents a key strategy for soil degradation prevention and climate change mitigation.

Winter wheat is one of the most important crops globally and also in Hungary. Hungary has excellent crop production potential including seed production. The aim of our experiment is to determine the effects of different amounts and proportions of nutrients and those of the seed size of winter wheat in laboratory seed tests on the seed parameters (germination percentage, germination power, seedling health and vigour), as well as in field tests of the seed parameters (emergence percentage and yield of next crop year). Laboratory seed tests of winter wheat variety GK Petur were conducted with seeds that underwent ten nutrient treatments and of three seed size fractions over four crop years, together with field experiments in three growing seasons. Compared to the untreated control group, N treatments significantly decreased the health of the seedlings in the next generation of winter wheat. PK treatments without N increased the germination percentage, vigour value and emergence percentage significantly, but the health of the seedlings decreased. In contrast, NPK treatments with a ratio of 2:1:1 improved all the tested parameters compared to those of the control group. The increase in seed sizes significantly increased the germination power, seedling health, vigour value, emergence percentage and the yield of the next crop year. It can be concluded that the factors of nutrient supply, crop year of the seed production and the seed size significantly influence the quality of the seed (germination percentage, germination power, seedling health, vigour and emergence percentage), thus also the yield of the next generation.

Agroecology is a discipline of science that is based on several disciplines, primarily ecology and agronomy. Although the first mention of agroecology was more than 100 years ago, it has recently been more intensely developed throughout Eastern European countries, beginning in the 1990s. Basically, such interest developed due to the intensification of agriculture in the second half of the 20th century, which was based on the premise of agricultural research, and related specifically to production. Agroecology is also strongly associated with sustainable agricultural activities, especially organic farming, which began to develop in Eastern European countries around 1990. Due to the unique environment of Eastern European countries, and a combination of several disciplines within them as well as other factors, agroecology in these differing countries can be perceived as somewhat different from one another. This overview focuses on the current state of agroecology in the Czech Republic, Poland, Hungary, Bulgaria, Romania, and Slovakia.

Intercropping is an ancient and worldwide agricultural practice expected to become more prevalent in Hungary due to the accumulating impact of climate change. In this study, the plant association of pure winter wheat (Triticum aestivum L.) and pure winter pea (Pisum sativum L.) was analyzed without weed control and with applied herbicides at different intervals (pre-emergence, early and late post-emergence) and different active herbicide ingredients. Two growing seasons, 2018–2019 and 2019–2020 were examined to compare weed composition and weed cover to evaluate the effect of the applied herbicides at different timings. To determine weed control efficiency, weed surveys were conducted six times in each growing season. The effect of cultivation methods (pure and mixed plots) on the development of plants was also measured by yield production analysis. Findings from these investigations indicate that there were significantly more weed species and occurrences of weeds in pure wheat and pure pea plots compared to mixed plots. In addition to cultivation and weed control treatments, meteorological events significantly influenced the development of the plants, and thus the yield components.

Food production and consumption have a major impact on the environment and human health. Therefore, it is important to achieve transformations towards greater sustainability in the food sector. As in other countries around the world, Hungarian organic food consumers are characterised by the fact that they consume organic food primarily for health reasons. Direct forms, including online purchase, are preferred in the choice of channels since direct contact with producers is very important due to mistrust, which is one of the barriers to the further growth of consumption. Empirical tests of well-known and frequently applied theories also shed light on the connections above. First, an examination was conducted through logistic regression to determine if there exists a correlation between organic food consumption and environmentally and socially conscious consumption traits (such as supporting small-scale producers) within the broader sample (1148), encompassing not just organic food consumers. Subsequently, concentrating solely on organic food consumers (944), factor analysis was employed to reveal connections among the analysed variables and to group Hungarian organic food consumers into clusters based on their consumption and purchasing habits. In conclusion, it is reasonable to assume that organic food consumers are more likely to be environmentally conscious, as they are more aware of the environmental impact of their food choices. Three clearly distinguishable groups were obtained using cluster analysis. These groups can be targeted with different means in order to develop the sector.

Organic tomato cultivation is growing all over the world due to its healthy functional properties and environmental concerns. Recently, some new varieties with increased functional properties, particularly high lycopene, have been developed. However, few were assessed under organic farming systems. The objective of this study was to evaluate physico-chemical properties and the main bioactive compound contents, as well as lipophilic, hydrophilic and total radical scavenging activities of a recently developed high lycopene tomato variety homozygous for hp-2^dg genes (HLT-F71) grown under organic conditions for two non-consecutive years (2019 and 2021) compared to the ordinary control ‘Nemador’ variety. The lycopene, β-carotene, total phenol, flavonoid, vitamin C, radical scavenging activity and tocopherols were analyzed by using spectrophotometric and HPLC methods, respectively. The high lycopene content variety presented suitable marketable yield, average fruit weight, pH, titratable acidity, firmness and higher °Brix, pulp color than the control. Additionally, it has significantly higher lycopene, β-carotene, total phenol, flavonoid, vitamin C and particularly considerable α-tocopherol contents, as well as radical scavenging activity. The high lycopene tomato variety with hp genes proved to be an effective sustainable variety for enhancing tomato fruit yield and functional properties even under organic grown conditions.
