This paper provides an overview of the progress of tillage in Hungary. The local and international impacts on the national practice are summarized, and some adoption of the conservation tillage results is presented concerning Hungary. The interest in conservation agriculture in Hungary dates back almost 120 years; however, any significant changes only occurred in the last 50 years. Interestingly, the factors of progress and restraint in tillage have appeared simultaneously over the years. Among the factors restraining tillage progress, the most retarding were the beliefs that have existed for many decades, as soil conservation was not considered nor was the need to mitigate climate-related hazards. Progress was driven by the commitment to soil protection, the opportunity to raise farming standards, and the need to mitigate climate-related threats. Since the average yield in Hungary was usually sufficient for the domestic need, the main objective of crop production was to avoid yield loss. Long-term experimental data and monitoring results were considered for this study. The impacts of new tillage solutions, elaborated in foreign countries, on tillage modernization were reviewed. The experiences and first results in no-till (direct drilling) and strip-tillage showed that difficulties can gradually be reduced through site-specific technology solutions. The need for subsoiling is not a matter of debate nowadays but rather the timing of operation and the investigation of the duration of the effects. Due to its complex advantages, tine tillage occupies an increasing rank among soil conservation systems. The area of ploughed soils has decreased; however, improved implementation is required.

After wheat and rice, maize is one of the most significant cereal crops worldwide. However, high-quality seed materials are prerequisites for stable yields, and low-quality maize seeds significantly contribute to low yields and deteriorate over time. Therefore, the present investigation aims to investigate the effects of seed quality and hybrid types on maize germination by emphasizing seed viability and vigor and their impact on maize crops’ overall performance and productivity. The study was separately conducted in the laboratory and on a field experiment plot under the Department of Crop Production, Hungarian University of Agriculture and Life Sciences, in spring 2022. Nine parental lines, six hybrids, and a controlled hybrid were tested in this study. The studies were laid out using a complete randomization design (CRD) and a randomized complete block design (RCBD) in the laboratory and in the field. The results of the study showed that there was a statistically significant difference between genotypes and number of days and their interaction in seed vigor. The parental lines showed better performance in terms of germination percentage and radicle elongation, whereas single-cross hybrids (SC) produced better plumule length. The radicle and plumule length also expanded significantly as incubation days increased. In field evaluations, as expected, hybrid lines produced better performance than parental lines, and SC hybrids were more prevalent than the other hybrids. In addition, the number of rows per ear, number of kernels per ear, 1000-kernel weight, and ear weight directly affected the final grain yield. However, further research is needed on new approaches that can assist researchers in advancing their work by considering biotic and abiotic factors to address seed-quality issues and enhance yield production.

Agriculture faces a significant challenge in maintaining crop production to meet the calorie demand of the ever-growing population because of limited arable land and climate change. This enforces a search for alternative multifarious agricultural-based solutions to meet the calorie demand. In search of alternatives, agricultural soil management has been highlighted and is expected to contribute to climate change mitigation through soil carbon sequestration and reduce greenhouse gas emissions through effective agricultural management practices. The addition of biochar to the soil significantly improves the soil nitrogen status, soil organic carbon, and phosphorus, with greater effects under the different tillage systems. This symbiosis association could further change the bacterial structure in the deeper soil layer which thus would be important to enhancing productivity, particularly in vertisols. Biochar also has an environmental risk and negative consequences. Heavy metals could be present in the final food products if we use contaminated raw materials to prepare biochar. However, there is a need to investigate biochar application under different climatic conditions, seasons, soil tillage systems, and crop types. These indicate that the positive effect of proper biochar fertilization on the physiology, yield formation, nutrient uptake, and soil health indicators substantiate the need to include biochar in the form of nutrients in the crop production sector, especially in light of the changing climate and soil tillage systems.

Precision sustainable agronomic practices are crucial for achieving global food security as well as mitigating climate change. A field experiment was conducted at the Hungarian University of Agriculture and Life Sciences in Gödöllő from 2023 to 2024. The study aimed to evaluate the effects of soil tillage and foliar nutrient supplementation on winter barley yield, associated characteristics, and soil CO₂ emissions. Employing a split-plot design with three replications, the experiment included four nutrient treatments (control, bio-cereal, bio-algae, and MgSMnZn blend) and two soil tillage type (i.e., plowing and cultivator). The study found that soil CO₂ emissions were influenced by the crop growth stage across both tillage treatments throughout the growing seasons, but the tillage system itself did not have an effect. Similarly, the leaf chlorophyll content was not affected by tillage and nutrient treatments. Plant height, the leaf area index (LAI), and thousand kernel weights (TKW) were significantly affected by nutrient treatments across the growing seasons. Both nutrient and tillage treatments also had a notable effect on the number of productive tillers in winter barley. Moreover, nutrient and tillage treatments consistently influenced grain yield across the two growing seasons, and their interaction significantly impacted both grain yield and thousand kernel weights. The bio-cereal nutrient treatment combined with plowing tillage yielded the highest values for most parameters throughout the growing seasons. Therefore, it can be concluded that the combination of bio-cereal nutrient treatments and plowing tillage can boost winter barley yields. Notably, soil CO₂ emissions peak during the crops’ reproductive stage, surpassing levels from early growth.

The granary weevil Sitophilus granarius L. is a pest causing substantial damage to stored wheat worldwide, against which the elaboration of sustainable control methods has recently been gaining importance. Our objective was to assess the efficacy of a rapid atmospheric convection heat transfer method against S. granarius under laboratory conditions. We examined the changes in adult mortality and progeny survival triggered by heat and the effect of this on the quality parameters of treated wheat items. The insecticidal efficacy, achieved by the treatment of infested grains, was also analyzed at 37, 47, 67, 87, and 107 °C for 5, 6, and 7 min under 40% and 60% rh exposure to atmospheric heating with the progeny production assessed 45 days after the treatment. The quality parameters of the treated wheat were analyzed by a germination test and NIR grain analysis. Our findings showed that adequate eradication of S. granarius was obtained at 107 °C for 5 min of exposure under suboptimal (40% rh) relative humidity values. At 60% relative humidity, mortality averages were more dispersed, and efficacies above the expected 95% occurred over longer exposures. The progeny-suppression effect from short-term heating was affirmed. The atmospheric convection heat transfer method, under the applied temperature and exposure time combinations, did not induce detectable changes in the quality parameters or the germination ability of the treated wheat. Overall, our findings indicated that the use of short-term heating for the post-harvest protection of cereals is feasible, which may contribute to the realization of residuum-free pest management and provide an effective and sustainable technique in integrated pest management.

This investigation scrutinized the yield, starch, and protein content of five distinct potato genotypes (Desiree, Borostyán, Piroska, Rubinka, and Rózsa) over 5 years of repetitive replanting. The experiment aimed to compare different potato genotypes and examine the yield reduction resulting from possible genetic deterioration over the years. The research took place in Zirc, Hungary’s temperate deciduous forest zone, at 450 m elevation from 2017 to 2021, on a 100 m² plot. Potato dry matter was measured according to MSZ 6369-4:1987, and starch content followed MSZ 6830-18:1988 standards. Tubers’ total nitrogen was gauged using the Kjeldahl method, while crude protein analysis employed the Dumas method. Pure protein evaluation adhered to the trichloroacetic acid precipitation technique, all consistent with WBSE-131:2018. Observed variations in starch content revealed Borostyán as the genotype with the highest mean starch content (75.41%) and Desiree with the least (74.98%). Protein content also varied among the genotypes; Borostyán exhibited the highest average level (10.99%), while Desiree had the least (5.52%). The remaining genotypes, Piroska, Rubinka, and Rózsa, exhibited comparable mean protein levels between 8.15 and 8.82%. Findings also noted a positive correlation between yield and starch and protein content. However, certain genotypes demonstrated a negative correlation, highlighting the impact of genetic factors and management practices such as nitrogenous fertilization and crop rotation on these associations. Additionally, the findings suggest that not only the standard Desiree variety but also the Borostyán variety can be reliably recommended for use in potato research and breeding initiatives. Conclusively, this study provides insights valuable for potato breeding and selection programs and the potential development of high-protein potato products. Further investigation is recommended to elucidate the mechanisms and genetic determinants that impact these observed relationships.
