Review on the fatty acid profile and free fatty acid of common carp (Cyprinus carpio)
99-105Views:384Carp or ponty in Hungarian, is considered commercial freshwater fish, which is an adaptable species in both wild and cultured conditions. Carp has high nutritional value content, favorable taste, it is rich in protein, and low in saturated fat. The nutritional content in fish is composed of many chemical constituents and influenced by many factors. One of the components that its content may be different due to internal and external factors is fatty acids, which may vary depending on endogenous and exogenous factors. The endogenous or internal factors include the genetic, size, sexual maturity, and life cycle phase. While microclimate, water quality, quality of food or diet habit, and the amount of available food or starvation are considered as exogenous or environmental factors. Freshwater fish has the ability to convert essential fatty acid into long chain polyunsaturated fatty acid like AA, EPA, and DHA. Most results showed that palmitic acid and oleic acid were the dominant SFA and MUFA in carp both for wild and farmed carp in all seasons. The PUFA for wild carp was mainly dominated by DHA, while on farmed carp by LA. It confirmed that high LA content in farmed carp was related to the diet habit. The amount of lipid and FA were changed in line with the season. Even the statistical analysis showed no significant difference, but some studies showed a contrasting result. Moreover, most obtained results acknowledged that FA tends to decrease during the spawning period. The amount and composition of FA were affected by the total lipid content. The lipid must be broken down into simpler compounds such as FA or FFA for the metabolism of fish. The result of metabolism then transported into the utilising tissue and used as energy.

Preliminary results of the combined production of duckweed Spirodela polyrhiza and common carp (Cyprinus carpio) in an aquaponic system
83-89Views:371As a result of population growth, increasin amount of food is needed, and agriculture is under an increasing burden to meet these needs. Traditional agriculture is often attacked due to its environmental impact. We must find alternative, environmentally friendly ways to produce more food. Aquaponics is a closed system in which we can produce both fish and plants at the same time. Duckweed species are small, aquatic, floating plants belonging to angiosperms. It can potentially be an alternative protein source, due to its high protein content, good amino acid supply, and rapid growth. Under suitable conditions, it doubles its weight in 2–4 days, and can reach a yield of 30 t ha-1 year-1in dry matter. It forms a carpet on top of the water and can be found in slow-moving or still waters. Since they are resistant to a wide range of nutrient concentrations, they are also suitable for cleaning wastewater (such as eutrophicated lakes, sewage reservoirs, liquid manure storage). Fish feed is the primary nutrient source for aquaponic systems, which usually contains fishmeal. If duckweed can be used as an alternative for fishmeal in the feed, it could improve the sustainability of the aquaponic and aquaculture systems. In this study, the aim was to develop an optimal harvesting protocol for duckweed Spirodela polyrhiza under aquaponic conditions. In a four weeks experiments, four harvesting protocols were set up, a control where only biomass measurements were made, a 25% group where 25% of the biomass at the time of measurement was harvested, and a 50% and a 75% group where at the time of measurement 50% and 75% of the biomass was harvested. Three replicates were used per treatment. We weighed the biomass every week and removed the amount corresponding to the group. Based on the preliminary results, it can be said that more biomass was obtained in the groups with the 25% harvesting protocol and the control group.

A review on the trend of livestock breeds in Laos
227-237Views:653When the livestock sector is considered an essential role in farmers' livelihood, and local breeds are still the critical component of animal breeding in Laos. Thus, there is a need to review the previous, current situation and prospects for Laos' livestock production. It aimed to study the different traits among the existing dominant local and improved livestock breeds (cattle, pig, and goat) and a more in-depth study on the livestock sector's previous evolving and prospects. Our findings revealed that the general trend of livestock population in Laos increased year-by-year for over 45 years, except for 1995 to 2000. It was decreased by almost 22% due to the new national strategy on economic revolution. The first foreign breeds were introduced into Laos, i.e., Large White, Landrace, and Duroc in 1980, Red Sindhi bulls in 1998, the frozen semen of Red Brahman 2003, and Bach Thao goats between 2001 to 2003. Unfortunately, many data are still not precise for introducing other foreign breeds like Boer goats, Thai Grey and Red Brahman. There were many missing data on the improvement of livestock breeds in Laos, including the local and improved breeds' reproductive and productive performance, which needs more study and research. We conclude that the semi-complex farm operation should be applied to improve livestock breeding and their productions in Laos.

Insect base-protein: A new opportunity in animal nutrition
129-138Views:824The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protein can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.
This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.
The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.
However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

The roles of mycotoxins in cereal crops production: A comparative study of Hungary and Tanzania
151-159Views:611Although Hungary and Tanzania's climatic, soil, and technological conditions differ significantly in crop production, cereals crop cultivation is of paramount importance; maize crop dominates the cultivated area (Hungary 1 million ha, Tanzania 3 million ha) both from a feed and food point of view. Unfortunately, in both countries, fungal species (Fusaria, Aspergilli, Penicillia, etc.) that produce various mycotoxins on cereals, including maize grains, are a growing concern. The situation is complicated because these fungal species and their toxins can appear not only on cereals but also on other crops. Despite the prevalence of mycotoxins in both countries, studies show higher exposure risks and contamination above tolerable levels for human consumption in Tanzania to Hungary, with Tanzania observing acute aflatoxicosis.

The R&D and innovation activity of agribusiness enterprises in Hajdú-Bihar County
67-71Views:207Economic changes have significantly accelarated in the 21th century. In this turbulent market environment enterprises are forced to adapt continously as they must be flexible in order to meet changing market needs. To achieve flexibility companies require innovation. The economic relevance of innovations is significant in every market sector and agriculture is no exception. Re-dynamizing agricultural innovations is a possibility for the outburst of the Hungarian agriculture. Agricultural enterprises have to face competitors as well and they should give priority to efficiency, sustainability and competitiveness in order to preserve their position in BOTH global and domestic markets. This study examines the innovation potential of the agricultural enterprises in the North Great Plain region based on own databases and case studies.

Awareness and adoption of a nurse sow management system among small-scale pig farmers in Nakuru County, Kenya
113-120Views:356This study aimed to assess the level of awareness and adoption of nurse sow management strategies among small-scale pig farmers in Nakuru County, Kenya. The research included a survey of pig farmers who visited the Nakuru Agricultural Show in July 2023. A total of 139 farmers were interviewed within 5 days of the show. The corresponding author interviewed the respondents in a face-to-face engagement, where questions on nurse sow management were initially drafted in English and translated into Kiswahili, i.e. the second language in Kenya. The obtained results indicated that farmers came from two main regions of the county: the northern part (54.7%, 76/139) and the southern part (45.3%, 63/139). Levels of awareness and adoption were insignificant between the two groups (χ2, p<0.05). A major obstacle to the adoption of this strategy was identified as feed challenge at 77.7%; (108/139) and market issue at 59.7%; (83/139). This study identified important aspects and limitations that should be considered when developing sustainable productivity development strategies for Kenyan pig farmers. To assist the sustainable growth of small-scale pig production, the authors suggest government measures that shield farmers against exploitation of feed and marketing components, as well as advocating for effective breeding to increase live born.

Effects of bioactive plant extracts on immune-related gene expression of common carp (Cyprinus carpio)
49-56Views:659In recent years, intensive fish farming has led to an outbreak of several diseases, and the health status of fish can affect the economy of aquaculture. Since fish health and intestinal health are in correlation, it may also have an impact on immunity. Accordingly, many natural feed additives are being used to improve immune functions. In our study, carotenoids, oligosaccharides, and anthocyanins were applied at 1 m/m% in feed to investigate their effects on cytokines, such as interleukin-1β (IL-1β), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and interferon regulatory factor-1 (IRF-1) in spleen and mid-intestine of 6 months old carp. Gene expression analysis was carried out to examine IL-1β, IL-8, TNF-α, and IRF-1 mRNA levels in fish spleen and mid-intestine. The gene expression level of pro-inflammatory IL-1β decreased in the mid-intestine of carotenoid-fed carp compared to anthocyanin supplemented group, but the effects of the bioactive plant extracts were not observed on the examined cytokines compared to control fish.

Heat stress of cattle from embryonic phase until culling
11-22Views:643Heat stress becomes a serious problem in the livestock sector as it affects cows' performance negatively. The objective of this paper review is to investigate the effects of heat stress during the different phases of the life cycle of cows; embryos, calves, heifers, and cows. Heat stress during early maternal gestation affects the ability of embryos to develop increasing the risk of abortion and early embryonic death. Heat stress during late maternal gestation affects the performance of calves and heifers later in their life, as it reduces growth performance, conducts physiological changes, impaired immunity, changes the behavior, and reduces the length and intensity of the estrus in heifers with decreasing in milk production in the first lactation. On the level of cows, milk quality and production, meat quality, and the final body weight decrease under hot temperatures. Heat stress decreases the conception rate, alters follicle growth, and estrous symptoms. Hormones secretion and physiological changes because of the heat stress conduct to impair the immunity system, and in oxidative stress and death in some cases. Same as for calves and heifers a change in the behavior of cows was detected in order to decrease their temperature.

Theoretical schools on employment and workforce
25-33Views:161In the civil economics, like in the case of any other socialeconomic issues, there are two coexistent theories concerning employment. On one hand we have the classical-neo-classical
school based on Adam Smith’s works. On the other hand we have the teachings based on John Maynard Keynes’ views. All the later hypotheses are based on these two trends.
Monetarism, which was invented at the beginning of the 20th century, mixes certain elements of both basic theories. Those who represent monetarism agree on rejecting the economy policy
means which affect the processes of the workforce market, while they consider these above mentioned means applicable to regulate certain processes. By the end of the 1970s the neo-classical macro-economics had developed, which completely refuses these approaches. A decade later the neo-Keynesian macro-economics developed. Its hypotheses regarding especially employment and unemployment lead to some of the employment issues of globalism, which is one of the most influential phenomena of present time. -
The use of Common duckweed (Lemna minor) as a biological filter in the rearing of hybrid African catfish (Clarias gariepinus x Heterobranchus longifilis)
107-112Views:530The African catfish (Clarias gariepinus x Heterobranchus longifilis) is one of the most important fish species in Hungarian aquaculture. The larvae and juveniles are reared at high feeding rates, which can reach up to 10% of the biomass. Intensive feeding results in large amounts of effluent water, directly proportional to the intensity of fish production. The aim of this experiment was to investigate the potential of Common duckweed (Lemna minor) as a biological filter and its nutrient removal capacity during intensive fry rearing of the hybrid African catfish. In a recent study, two experimental recirculation systems, identical in water volume and design, were set up, in one of which duckweed was grown under aquaponic conditions, where the concentrations of nitrogen and phosphorus forms were monitored and the production parameters of the fish were determined. The results obtained from the experiment showed that the use of duckweed as a biological filter improves the water quality of the recirculation system. A significant amount of plant biomass was produced, which mainly reduced the nitrate and orthophosphate concentrations in the system water. As a consequence, the survival of hybrid catfish was improved, which also affected biomass growth, but had no effect on other parameters.

Effects of water deficit on the growth and yield formation of maize (Zea mays L.)
143-148Views:303Maize (Zea mays L.) is the most important consuming cereal crop in the world after rice and wheat. This requires an understanding of various management practices as well as conditions that affect maize crop performance. Water deficit stress during crop production is one of the most serious threats to crop production in most parts of the world and drought stress or water deficit is an inevitable and recurring feature of global agriculture and it is against this background that field study of crops response to water deficit is very important to crop producer and researchers to maximize yield and improve crop production in this era of unpredicted climatic changes the world over.
A pot experiment was carried out to determine the effects of water deficit on growth and yield formation of maize. Two maize cultivars were used Xundan20 and Zhongdan5485. Three levels of soil water content were used in two stages of water control levels at two stages of the maize plant development
1. The JOINTING STAGE: A. CONTROL (CK) soil water content: from 70% to 80% of soil water holding capacity at the field, soil water content: from 55% to 65% of soil water holding capacity at the field, soil water content: from 40% to 50% of the Soil water holding capacity at the field.
2. The BIG FLARE PERIOD: A. CONTROL (CK) soil water content: from 75% to 85% of soil water holding capacity at the field, soil water content: from 58% to 68% of soil water holding capacity at the field, soil water content: from 45% to 55% of the soil water holding capacity at the field.
This research mainly studied the effects of water deficit on physiological, morphology and the agronomical characteristics of the maize plant at the different water stress levels.
The importance of these results in this experiment will enable plant producers to focus and have a fair idea as to which stage of the maize plant’s development that much attention must be given to in terms of water supply. -
Effects of agrotechnical factors on the quality and quantity of yield in winter wheat production
69-75Views:378The present study was conducted to determine the effect of basic agrotechnical factors on the yield and quality of winter wheat. Two experiments were set in 2017/2018 growing season, where we studied the influence of different forecrops, fertilizing treatments and cultivars. 204 samples were measured with Single Kernel Characterization System and NIR grain analyser to determine protein (NIR-P), wet gluten (NIR-WG), Hardness Index (HI), kernel weight (KW) and kernel diameter (KD). Fertilizing had a significant effect on yield, KW, HI, NIR-P and NIR-WG, except KD. N90PK dosage was enough to realize yield potential for 6 out of 9 cultivars, but considering protein content N150PK dosage was needed. The forecrop had no significant influence on yield, KW, KD or HI, however sweet corn as previous crop had significant improving effect on NIR-P and NIR-WG compared to sunflower as forecrop. According to our data of correlation analysis, no negative relationship was found between yield and NIR-P, however HI was in medium positive correlation with NIR-P. The variety Vyckor had the highest yield, but in quality aspect, the highest NIR-P and NIR-WG values belonged to KG Kunhalom variety.

Evaluation of the use of leaf fertilizers and growth regulators in winter wheat: A review
77-82Views:225Winter wheat is a leading cereal on a global scale, however, yields remain variable due to increasing weather extremes. This review synthesizes evidence (1971–2024) on the effects of foliar fertilizers and plant growth regulators/biostimulants on wheat growth, yield and quality. Across studies, appropriately timed foliar micronutrient applications (Fe, Mn, Cu, Zn, B, Mo) tend to enhance chlorophyll content, photosynthetic activity, and grain quality traits, while selected copper- and zinc-based products frequently increase grain yield and crude protein. Biostimulants—such as amino acids, humic/fulvic acids and seaweed extracts—generally improve stress tolerance (drought, cold) and may raise grain number and thousand-kernel weight. Plant growth regulators (e.g., lodging control agents) can reduce plant height, strengthen stems and improve stand stability, thereby contributing to yield security. Evidence magnitude varies with soil supply, cultivar, and phenophase-specific timing. We summarize practical windows of application, expected responses, and limitations, and highlight research gaps in standardizing doses and reporting effect sizes. Overall, foliar nutrition and growth regulation are promising tools to increase yield stability and quality under increasingly variable growing conditions.

The effect of β-glucan, carotenoids, oligosaccharides and anthocyanins on bacteria groups of excreta in broiler chickens
15-20Views:706This study was conducted to examine the effect of natural compounds, such as β-glucan, carotenoids, oligosaccharides, and anthocyanins in the diet on bacteria gropus of excreta in Ross 308 broiler chickens. Chickens were fed 5 diets: control (basal) diet, a diet supplemented by β-glucan at 0.05%, and diets supplemented by carotenoids, oligosaccharides, or anthocyanins at 0.5% of each compound. On experimental day 19, excreta were collected to determine the proportion of Lactobacillus, Bifidobacterium, Campylobacter, Clostridium, and Escherichia coli. Samples were collected aseptically and snap-frozen in liquid nitrogen. Bacterial DNA was isolated from samples, then polymerase chain reaction using primer pairs designed to the 16S rDNA of bacterial groups were applied to define the proportion of the mentioned bacteria. Another universal primer pair was used to amplify a region of 16S rDNA of all the examined bacteria. Proportion of each bacterial groups was determined relatively to the intensity of universal PCR product band by gel documenting system and ImageLab software. Based on the results, carotenoids and anthocyanins increased the proportion of Bifidobacterium, which might imply the beneficial effects of the mentioned compounds on the bacteria composition of excreta.

Examination of the presence and effect of udder edema in Holstein-Friesian cattle
125-130Views:312Mastitis is the most common disease of dairy cows and the most expensive in terms of treatment. For this reason, great emphasis must be placed on its prevention. Based on literature sources, it can be said that there is a positive correlation between the prevalence of udder edema and the occurrence of mastitis. Our studies were carried out in a dairy farm in Csongrád-Csanád county. So far we have collected data from 64 cows with udder edema. The severity of udder edema was evaluated on a scale of 0–3 points one week before calving and for 3 weeks after calving. We observed that udder edema occurred in 78% of the studied cows at the time of the first calving. After calving, the length and diameter of the four udder teats were examined. Both anterior and posterior teats were shortened in severely edematous cows. When examining the diameter of the teat, we found that, depending on the severity of the edema, the anterior and posterior udder teats were 2.5 and 1.6 and 1.6 and 1.5 mm thicker respectively than those of cows without edema.

The potential use of Pediococcus spp. probiotic in aquaculture: A review
99-106Views:537Aquaculture production has significantly increased over the previous few decades. However, antibiotics have been implemented regularly and extensively to overcome outbreaks of pathogens in aquaculture to cover the human needs for animal protein, leading to the appearance of resistant strains that may cause serious damages in the environment and also human health. In the last few years, the implementation of probiotics as an alternative technique to antibiotics use in fish production has achieved promising results in aquaculture due to their beneficial impact on fish health and growth performance. Among different types of probiotics, the Pediococcus spp. bacteria stand out as a promising probiotic for their beneficial impact to aquaculture. Thus, the current study has been conducted to give an overview about the interactions between Pediococcus spp. and aquaculture. In addition, this review highlights the role of Pediococcus spp in promoting growth performance, improving feed conversion ratios and the intestinal architecture, enhancing the immune response and inhibiting fish pathogens, thereby preventing or at least reducing the use of antibiotics. Practical use of Pediococcus spp. probiotic in aquaculture as feed additives through selected case studies is also considered.

Evaluation of Lipizzaner mares’ fertility data in 10 Hungarian stud farms
23-26Views:59Despite numerous studies on the genetic background and performance traits of the Lipizzan breed, fertility characteristics of Hungarian Lipizzan mares have not been systematically examined. This study evaluates the reproductive performance of 220 Lipizzaner mares from 10 Hungarian stud farms, born during the period of 1981 to 2019, using breeding records from 1998 to 2022. The mares were grouped into 25 mare families and 24 birth cohorts. Data on successful pregnancies and foalings were analyzed with respect to age, family affiliation, and breeding year. Results show that mares aged 8–12 years had the highest fertility rates, while a gradual decline was observed after 15 years. Breeding activity increased markedly after 2011, peaking in 2022 with the highest number of matings and foals born. Fertility varied considerably among mare families: some achieved consistently high reproductive success, while others showed low or zero foaling rates despite repeated matings. Hungarian mare families generally produced better fertility results, whereas Fogaras families displayed greater heterogeneity. The study emphasizes the importance of monitoring reproductive efficiency in small mare families, as unfavorable fertility trends may jeopardize their long-term viability. These findings contribute to improving breeding strategies and ensuring the preservation of genetic diversity in the Hungarian Lipizzaner population.

Changes in the relationship between Hungarian Grey cows (Bos primigenius taurus hungaricus) and their calves in the period from calving to four months of age
85-90Views:473The ability of cows to care for their offsprings is a very important trait concerning beef cattle. Maternal instincts are highly influenced by breed, specific cow, and social and rearing environment. In 2020, at the Szamárháti farm of the Tiszatáj Public Foundation, we selected 15 dam-calf pairs and studied them for four months from the birth of the calves. We grouped calf-rearing behaviors according to strength and analyzed the related changes during the program. At the beginning of the relationship, "standing close to each other" (53%) and "suckling" (24%) characterized the pairs. After the first month, "standing or lying separated" grew by 69%, and "vocalization" by both animals fell by 66%. Even though the daily frequency of suckling decreased by 34% as the calves grew older, it remained a typical element of the relationship. Over time, the bond between the animals gradually weakened. This natural process of separation takes a month to complete.

An overview of swine production and marketing in Africa - Mini review
121-129Views:543Pigs are the oldest domesticated animals, though their ancestry is still uncertain because of a lack of archaeological and genetic evidence. Pigs serve a vital role in reducing the demand for livestock and livestock products in most parts of the world. Especially in the African continent, pigs serve as mobile cash implying how easily they can be converted into cash to sort pressing family needs. Pig production in Africa is different from advanced systems of production in temperate countries, however, it has similarities with most of the tropical low and middle-income nations. Pig production in Africa requires attention to enable it to contribute effectively to the growing African population. However, it has been orchestrated with a myriad of challenges including market access. This mini-review is designed in a manner to provide an overview of pig production contribution to livelihoods in Africa and associated challenges with possible appropriate solutions.

Routine microscopy examination of faecal samples as a tool for detection of common gastrointestinal parasites: a preliminary report from two Hungarian farms
63-66Views:344Gastrointestinal parasitism in ruminant animals is a cause of major economic loss incurred by the livestock industry. Regardless of the frequency of the adopted therapeutic and prophylactic deworming strategies, the parasitic burden in a farm should be assessed regularly. One of the most widely used techniques to do so is the microscopic faecal egg examination and faecal egg counting method. Despite the technique being almost a century old from its first adoption, the principle behind the newer techniques of faecal egg examination is the same. This technique is still being used in routine farm screening and monitoring gastrointestinal parasitic load and faecal egg count reduction testing to assess the anthelmintic efficacy of the drugs used. Thus, the tool remains a choice for preliminary screening for important parasites and the subsequent deworming strategy. Our study here was part of a larger survey on the treatment efficiency as well as a broad epidemiological study of the trichostrongyle parasites in Hungary. We present a preliminary report on the detection of common gastrointestinal parasites from two farms in Hungary, including a species-specific confirmatory microscopy for Haemonchus contortus eggs.

Remembrance to László Huzián (1923-1996)
5-11Views:231László Huzián was a determining personality of the higher education of Hungarian crop protection more precisely that of the agricultural entomology. Training of the scientific and extension specialists of Hungarian agricultural entomology from 1960 till 1983 would have been unimaginable without him. He was the builder of the agricultural entomology school established by Gusztáv Adolf Manninger, the developer of the training’s essential and organisational standard, who sacrificed his life’s work for developing the crop protection. He found, characterized many pests (E.g. Scrobipalpa ocellatella, Lixus scabricollis, Tanymecus palliatus, Mesagroicus obscurus) new for the Hungarian fauna and worked out a control technology against them. It is important to mention his activity in creating the forecasting of the big field crop animal pests mainly that of the sugar beet pests. One top of his educational work was the wonderful manual „Agricultural Entomology” written with Sándor Bognár in 1979. László Szalay-Marzsó said of this book that it was impossible to write a better one. He has been right. The magnificent crop protection library and the unique richness and accuracy of the animal demonstration material (slides, pictures, preparates, showcases, etc.) established at the Gödöllő University of Agriculture can be thanked to his extraordinary systematizing mentality and tireless efforts.

Effects of cultivation practices and hybrid selection on endofusariosis and mycotoxin contamination in maize
69-78Views:425The 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.
