Effects of cultivation practices and hybrid selection on endofusariosis and mycotoxin contamination in maize
69-78Views:388The aim of this study was to determine the levels of deoxynivalenol (DON) and fumonisin mycotoxins in tillage and no-till systems in 2020 and 2021. Additionally, we sought to establish the levels of internal Fusarium infection in different tillage systems. We examined four tillage systems for two years (conventional tillage (plowing), conservation tillage, reduced tillage, and strip-till). The results indicate that toxin levels varied between the two years, with fumonisin production dominant in 2021, while DON toxin production was dominant in 2020. Regarding internal Fusarium infection, the lowest levels were observed in the plowing system in 2020, whereas in 2021, the lowest levels were measured in the reduced tillage system. Like the low DON levels in 2020, the plowing-based tillage system resulted in the lowest fumonisin levels in 2021. Throughout our experiment, the toxin levels were below the permissible limits for unprocessed corn, with DON levels under 1750 μg kg-1 and combined fumonisin B1 and B2 levels under 4000 μg kg-1. However, in areas where toxin contamination is typically problematic, considering the beneficial impact of plowing on reducing toxin contamination might be advisable when planning tillage.

Current Conditions and Opportunities of Biofarming in Hungary
150-156Views:201The aim of organic farming is not to maximize income, but to achieve optimal product quality. It is completed by the tightest possible material, and energy flow within the farm. Organic agriculture significantly reduces external inputs by avoiding the use of chemo-synthetic fertilizers, pesticides and pharmaceuticals. Instead it works with nature to increase both agricultural yields and disease resistance. Total independence of external resources can not be achieved in Hungary due to the small-scale of organic animal husbandry. Some materials in limited quantities can be purchased from external resources, though the group of these materials is strictly regulated. Organic farming harmonizes with the concept of European multifunctional agriculture, because besides farming, it includes social considerations, as it helps to maintain natural resources and the relationship between people and their environment, and provides a living for those living in the region.
As regards organic farming the fertility of the soil and the health of vegetation can be influenced in various ways. Farmers have to be highly skilled and able to manage a farm with great expertise. Generally it can be stated that as the use of non-organically produced products is limited, the opportunities to correct failures made by the farmer are minimal, contrary to conventional farming. Farmers must be intent on developing the tightest material- and energy flow. This means that organic farms ideally have both animal husbandry and crop production. This energy and skill demanding system of farming is compensated by state subsidies, growing market share and relatively high prices for organic products. -

Comparison of chemical parameters of enzyme active and inactive malt types
161-166Views:371Nowadays there is an increasing emphasis on the use of raw materials. Typically, raw materials – in this study malt – are used in animal feeds and used in the brewing industry. However, in terms of quality (eg. high fibre content), these can be included in human nutrition, we have limited information on this possibility. The aim of our work was to compare different malt flours and examine the possibility of using malt in the baking industry. We were to investigate some of the most relevant parameters, such as dietary fibre content, crude protein content, fat content, carbohydrate content, dry matter content, moisture content, salt and energy content. In the future, we aim to conduct a research on some of these parameters with different malt types as the brewing industry uses novel ingredients different cereals, pseudocereals such as amaranth (Amaranthus spp.), oat (Avena sativa L.), quinoa (Chenopodium quinoa Willd.) in addition to the spring barley (Hordeum vulgare L.) or wheat (Triticum aestivum L.). Based on brewing studies, malt has a high fibre and protein content. Having these advantageous qualities, malt should be part of humans’ healthy diet. Using malt flour in the baking industry can be a new direction which can lead to creating a healthier lifestyle and healthier eating habits than suggested by the WHO (World Health Organization).

Maize nutrient dynamics: growth, yield and sustainable practices: A narrative review
83-91Views:22Nutrient acquisition is the fundamental regulator of maize (Zea mays) growth, development, and yield. The present narrative review intends to integrate existing information on dynamics of nutrient uptake in maize under scrutiny for understanding how the processes affect growth and yield. We focus on the effective absorption and utilization of macronutrients (N, P and K) and micronutrients that promote plant health, grain development, and stress tolerance. Key determinants of nutrient availability (soil type, pH, organic matter, environment) and physiological or yield impacts of deficiency are studied. Strategies to optimize uptake efficiency precision application of fertilizer, organic fertilizers, and sustainable soil management are discussed. Optimizing these dynamics is central to maize productivity, enhancement and sustainable crop production. This review provides valuable insights into optimizing maize nutrition for improved food security and sustainable crop production.

Effect of soil-compost proportion on the abiotic and biotic parameters of soilplant system
99-104Views:286The environmental awareness, coming to the front in the 21st century, motivates us to supply the plant nutrient demand (in point of the plant, the environment and the human health) with natural materials.
Composting is known since the beginning of civilization. We came to know more the processes of composting as a result of last decades’ research, but numerous unexplained questions remained up to this day. The good compost is dark gray or brown, and it should not create an odor. It has aggregate structure, and it’s pH is neutral. Compost is soil-like (Fehér, 2001), nutrient-rich material, which contains valuable nutrients extracted from soil, so if we recycle this, we can decrease the chemical fertilizer and other (example: mineral energy) expenses.
The reason of that we chose the more accurate cognition of compost utilization is to do more effective the site-specific nutrient supply. This increases the average yield and the quality of yield. Besides we can decrease the harmful effects, which endanger the plant, the environment, and the human body.
During the compost utilization experiment we blended the acid sandy soil with compost in 4 different volumetric proportions (5 treatments) than we set the pots randomized. The advantage of this method is that we can provide equal conditions for plants so we can measure the effect of treatments correctly. Our experimental plant was ryegrass (Lolium perenne L.), that grows rapidly, tolerates the glasshouse conditions, and indicates the effect of treatments well. After the harvest of ryegrass we measured the fresh and dry weight of harvested leaves and the total C-, N-, S-content of the dry matter and of the soil, we examined the pH and the salt concentration of soil as well.
Our aim was to study and evaluate the relations between the compost-soil proportion and the nutrient content of soil and plant. In our previous experiments we confirmed (based on variance analyses) that the compost has a beneficial effect on soil and increases the nutrient content of the soil (Szabó, 2009). But it’s important to appoint that the compound of compost is seasonally change: in winter the selective gathered municipal solid waste contains salt that were applied for non-skidding of roads, but salt has a negative effect to the plant. We proved that in our experiment the 25/75% compost/soil proportion was ideal for the plant. This content of compost effected 6 times higher green matter weight compared to the 100% sandy soil. -
The toxicity of different selenium forms and compounds – Review
33-38Views:2223Selenium (Se) is an unusual metalloid of considerable interest from both a toxicological and a nutritional perspective, with a very narrow safe range of intake. Although there are many reports about its detoxification properties, toxicity aspects of it have also been tracked for several decades. Lots of studies demonstrated that low Se is an efficacious avail whereas high Se can induce toxicity and the significant toxicity of selenium emphasizes the need to assess the health risk of various selenocompounds as nutritional supplements. The toxicity of different forms and compounds of selenium is also summarized in this review.

Global tendencies in turkey meat production, trade and consumption
83-89Views:723Global meat production totaled 357 million metric tons in 2021. Poultry accounted for nearly 40 percent of total meat production, including 4.2 percent of turkey meat (5.8 million tons). Global turkey meat production has stagnated between 5.5 and 6.0 million tons since 2008, in contrast to the monotonous upward trend in poultry meat production. Turkey meat production generally occurs under well-integrated conditions, with some large multinational companies and smaller, regional players. The industry is exposed to a number of factors that affect supply and demand, including disease outbreaks, government regulations, consumer preferences, and economic conditions. Key factors driving market growth include population growth, urbanisation, and increasing consumer awareness of the health benefits of turkey meat over other meats. In addition, advances in processing, packaging, and distribution technology have improved turkey meat's shelf life and availability, further fueling growth. Turkey farming and production are mainly concentrated in certain regions such as North America and Europe, where industrialisation has a long history and infrastructure is well developed. Turkey meat production in these areas is sufficient to meet local demand and is often exported to other regions. However, in other regions where turkey farming is less developed, such as parts of Asia and Africa, turkey meat production is insufficient to meet local demand. This type of meat must be imported from other regions. The degree of self-sufficiency in turkey meat depends on the level of development of the sector in each region. This study investigates the factors affecting global and regional markets for turkey meat and systematised the development of global consumption, production, and trade of turkey meat.

Stevia (Stevia rebaudiana B.) yield in the case of different production technologies
71-77Views:321Stevia rebaudiana B. offers a natural alternative of sweetening, potential health promotion plant, and our country shows increased interest about cultivation in Hungary in addition to the neighboring European countries. The agricultural production system installation necessary
understanding of the needs of the plant, as well as exploring the agronomic potential. Field experiments were conducted in 2015 with the aim to highlight some of the technological production parameters and correlations between them. We have reviewed the most important agronomic factors, the spacing (50×50 cm and 33×33 cm), ground covering (agro-cloth covered and uncovered/ control), their vegetative growth (first-,second-order branch), herb yield and quality in effect.
Based on empirical evidence, that the Hungarian climates also have the opportunity of 3 cuttings during a growing season, besides of early planting, optimal climatic conditions (in October didn’t reduce the daily minimum temperature below 0 °C, after cuttings the maximum interval values remain below 40 °C), and adequate water supply and crop protection facility. The 33×33 cm spacing evaporates more than 50×50 cm spacing, because of the dense population, the continuous canopy less able to breathe, so there are serious chances to the pathogen colonization.
Based on the results of our research to the wider 50×50 cm spacing favorable appreciate the stevia optimal progress in terms of qualitative and quantitative parameters of the yield. The stevia yields produced in the Northern Great Plains field cultivation can produce similar results as stevia crop yields in warmer climates, where the primary crops. Our research experience suggest that there is a viable domestic stevia cultivation, developing the necessary technology is still growing further investigation justifies.
