Soil salinity is a severe and expanding soil degradation problem that affects 80 million ha of arable lands globally. Chickpea (Cicer arietinum L.) is very sensitive to saline conditions; the most susceptible genotypes may die in just 25 mM NaCl in hydroponics. Approximately 8–10% yield loss in chickpea production is estimated due to salinity stress. However, it is still not established why chickpea is so susceptible to salt affection. Salinity (NaCl) impedes germination of seeds, though chickpea varieties considerably differ from one another in this respect. Some chickpea genotypes are more tolerant in the stage of germination, tolerating even 320 mM NaCl. The reasons of this variation are unrevealed; there is a shortage of knowledge about the germination abilities of chickpea genotypes in saline conditions. Nevertheless, the effect of salt stress on vegetative growth can be analysed in hydroponics, in pot or field conditions, regardless the experimental environment, the ranking of genotypes regarding salt resistance is coherent. Chickpea genotypes can be different in their ability to retain water, maybe under salt affection; the more salt tolerant lines can maintain higher water content in the shoots, while the more sensitive ones cannot. The identification of salt tolerant chickpea landraces based on developing genetic variability is a suitable strategy to combat against salinity problems arising in arid and semi-arid areas.
土壤盐碱化是一个严重且不断扩大的土壤退化问题，影响着全球8000万公顷的可耕地。鹰嘴豆(Cicer arietinum L.)对盐水条件非常敏感;最敏感的基因型在25 mM NaCl的水培中可能死亡。据估计，由于盐胁迫，鹰嘴豆产量损失约为8-10%。然而，鹰嘴豆如此容易受盐的影响的原因仍未确定。盐(NaCl)会阻碍种子的萌发，尽管鹰嘴豆品种在这方面差异很大。有些鹰嘴豆基因型在萌发阶段的耐受性更强，甚至可以耐受320 mM的NaCl。造成这种差异的原因尚不清楚;关于鹰嘴豆基因型在盐水条件下的发芽能力，目前还缺乏相关的知识。尽管如此，盐胁迫对营养生长的影响可以在水培、盆栽或田间条件下进行分析，无论实验环境如何，耐盐基因型的排名是一致的。鹰嘴豆基因型在保水能力上可能是不同的，可能在盐的影响下;耐盐品系能保持较高的芽部含水量，而耐盐品系不能。在发展遗传变异的基础上鉴定耐盐鹰嘴豆地方品种是解决干旱和半干旱地区出现的盐碱问题的一种合适策略。

Organic soy production, particularly for feedstuff in organic animal husbandry, is needed in Hungary and the EU regions. Soybean producing crop area in Hungary has increased in the last years, however, the agroecological potential would allow for a larger soybean production area. This study presents the soybean market in Hungary, and the role of soybeans in protein supply in food and feed, summarising the critical elements of organic soybean production from variety selection to marketing. During the field research, the effects of the agronomical environment on yield potential factors were examined. We aimed to determine how different row spacing and tillage systems affect organic soybean yields of different varieties, with particular attention to the dry region, and determine the specific methods and varieties of soybean that favour these areas. We found that the tillage (plough/grubber), the spacing (wide/narrow), and the variety effects were all significant on morphological variables. The most remarkable difference was seen in plant height and the number of pods per plant, while the number of nodes was also highly impacted by tillage treatment and variety. The nutrition variables were significantly different, mainly as an effect of tillage and spacing interaction with significantly different plant responses of varieties.

The ability of wood products to store carbon allows for their significant contribution to the climate mitigation efforts and the emission reduction commitments set by the EU. In order to optimise the carbon storage capacity of wood products, it is important to take climate mitigation aspects into consideration as much as possible during their production, use and waste management. The aim of this study was to quantify the effects of product development, recycling, and waste management technologies on carbon storage and emissions. In the frame of the ForestLab project, a new model and decision support tool was developed, which is able to predict the duration of carbon storage of wood products and the evolution of emissions from them. The developed HWP-RIAL model (Harvested Wood Product Recycling, Incineration And Landfill model) uses the methodology of the Intergovernmental Panel on Climate Change (IPCC) to calculate emissions, which is also used in the National Greenhouse Gas Inventory report. It combines the IPCC waste model with equations describing the carbon storage and emissions of wood products, and the model is also supplemented with a self-developed recycling and waste routing module. This paper provides insight into the operation of the model by following the life cycle of 200,000 m3 particle board.

Mastitis 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.

For thousands of years, chili pepper has been used in cooking intensifying the aroma, colouring, and even flavouring with its pungency. Today ,it is also of interest for the various food and pharmaceutical industries due to its intrinsic characteristics. These characteristics of pepper and its yield can be affected by both the variety and the temperature fluctuation throughout the harvest period. The current work's objective was to investigate the effect of harvest time on vitamin C of different varieties of chili pepper C. frutescens and C. annuum cultivated in Hungary, as well as the yield of pepper in different harvesting periods. Vitamin C was determined by HPLC protocols. The differences between harvest times and varieties were analysed using Tukey post hoc test at 5%. All varieties showed fluctuation of vitamin C level, depending on the given harvest date. At the last harvest, all varieties had higher vitamin C content. All varieties had the same yield trend throughout the year but with different yields between each. Variety Hetényi Parázs had the highest vitamin C content and yield: 3720.53 µg g-1 vitamin C and 18.63 t ha-1 average yield, respectively.
几千年来，人们一直用辣椒来烹饪，用它的辛辣味来增强香气、着色，甚至调味。今天，由于其固有的特性，它也引起了各种食品和制药行业的兴趣。辣椒的这些特性及其产量会受到品种和整个采收期温度波动的影响。本研究的目的是研究不同采收期对匈牙利不同品种辣椒C. frutescens和C. annuum维生素C含量的影响，以及不同采收期辣椒产量的影响。采用高效液相色谱法测定维生素C。采用5%的Tukey事后检验分析了采收期和品种之间的差异。所有品种的维生素C含量都随采收日期的不同而波动。在最后一次收获时，所有品种的维生素C含量都较高。各品种全年产量趋势一致，但各品种间产量差异较大。品种hetsamunyi Parázs维生素C含量和产量最高，分别为3720.53µg g-1维生素C和18.63 t ha-1平均产量。

Greening crops play an essential role in Hungary's agriculture. Weeds can also cause many problems during the development of greening plants. Our research aimed to evaluate the weed control properties of greening crops sown with different germination rates. Analysis of the effect of crop rotations on weed density. Comparison of weed growth in control, fertilised and greened areas. In October of 2021, a weed survey was carried out in lupin (Lupinus albus L.), common vetch (Vicia sativa L.), oil radish (Raphanus sativus var. oleiferus L.) and buckwheat (Fagopyrum eculentum Moench). During the weed survey, we determined the different weed species and their abundance. In terms of seed rates, the higher seed rates for lupin, oil radish, and buckwheat may be worth choosing for weed suppression. Plots in rotation III had the lowest weed incidence of all greening crops. The probable reason for this finding is that there was no prior greening in rotation III. For greening, the choice of buckwheat and oil radish will result in higher weed pressure. The most important weeds were the cereals sown before the greening crop. Fertilised plots had minimally fewer weeds than control plots. Research results show the difficulties of weed control in herbicide-free greening crops.

The effect of two diets with different fibre contents was examined on rabbit does’ performance and parasitological infection. Diet P2 had 1% higher crude fibre, ADF and starch contents than that of diet P1. The performance of 12–12 does and litters per group were examined during two consecutive inseminations. In both dietary groups, according to a 49-day reproduction rhythm, the does were artificially inseminated 18 days after kindling. Most production traits were not affected by the diets (kindling rate, weight of does and their kits, feed intake, mortality; P>0.05). Significant differences were only found in litter sizes as the number of kits was lower in P1 diet fed group at all examined days of lactation. The significant “Diet x Reproduction cycle” interaction showed that the litter sizes of dietary groups did not differ at the first examined insemination, however at the subsequent reproduction cycle 6–8% lower litter sizes were counted in P1 fed does compared to group P2 (litter size at 4 day: 9.00 vs 9.58–9.92, P = 0.004; litter size at 11 day: 8.83 vs 9.58–9.92, P = 0.037 for diet P1 at the 2nd reproductive cycle compared to all the other cases, respectively). The two diets with different compositions did not affect most of the production results of the rabbit does and their kits, but the lower litter size of does consuming P1 diet at the second examined lactation suggests the adverse effect of P1 diet’s long-term use. From the collected manure samples not any parasites were detected which presents a very favourable picture of farm from the point of view of hygiene and animal health.
研究了两种不同纤维含量饲粮对家兔生产性能和寄生虫感染的影响。饲粮P2粗纤维、ADF和淀粉含量比饲粮P1高1%。在连续两次授精期间，观察每组12 ~ 12只公羊和窝仔的生产性能。在两个饮食组中，根据49天的繁殖节律，在点燃后18天进行人工授精。大多数生产性状不受日粮的影响(点火率、公羊及其雏重、采食量、死亡率;P> 0.05)。在所有检查的泌乳天数中，P1饲粮组的产仔数较低，仅在产仔数上存在显著差异。显著的“饲粮与繁殖周期”交互作用表明，饲粮组的产仔数在第一次检测授精时没有差异，但在随后的繁殖周期中，P1饲喂的产仔数比P2组低6-8%(第4天产仔数:9.00 vs 9.58-9.92, P = 0.004;第11天产仔数:第2繁殖周期饲粮P1与其他各组相比分别为8.83 vs 9.58 ~ 9.92, P = 0.037)。两种不同成分的饲粮对家兔及其窝仔的生产结果影响不大，但在第二次泌乳时，饲喂P1饲粮的家兔产仔数较低，说明长期使用P1饲粮会产生不利影响。从收集的粪便样本中未检测到任何寄生虫，从卫生和动物健康的角度来看，这显示了农场非常有利的情况。

Gastrointestinal 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.

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.","PeriodicalId":7365,"journal":{"name":"Acta Agraria Debreceniensis","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74064546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leaf litter decomposition is one of the main ecological material cycle processes in waterfront areas. In this microcosm experiment, the rate of decomposition of the most frequently occurring dominant waterside plants were examined in the summer months of 2022 in a class “A” evaporation pan, using litterbag technique. The study provides information about the decomposition dynamics of willow (Salix sp.), poplar (Populus sp.), reed (Phragmites australis) and different leaf litter mixture combinations. Dry mass, exponential decay coefficient and the chemical parameters of the water (pH, conductivity, NH4+, PO43-, SO42-) were determined during the 84 days long experimental period. The weight loss curves showed negative exponential pattern in every case. On average, the different samples lost ~ 57% of their initial dry mass during the experimental period. The largest mass loss was measured in case of poplar (67.2%), while reed leaves had the smallest mass loss (47.25%). Based on the results, it cannot be proven, that mixed leaf litter accelerates the rate of decomposition.

AIt is a huge challenge for farmers worldwide to successfully increase the organic matter content of their soils and improve their water balance at the same time. Therefore, the main aim of the study is to develop and test organic-based nutrient composite materials that can be successfully used by farmers to increase soil organic matter content, improve water management parameters and implement water-efficient technologies. The study was performed in the orchard of the Institute of Horticultural Science of the University of Debrecen in Hungary (Debrecen-Pallag). The experiment was set up in a ten-year-old apple (Malus domestica ‘Pinova’) orchard. In the trial, fermented poultry manure and superabsorbent polymers (SAP) were used at different doses to study their effects on soil properties and fruit quality. Applied composite materials increased the nitrate and organic nitrogen content of the soil. Treatments did not affect the sugar content of the fruits but significantly and positively affected the individual fruit weight and the titratable acidity of the fruits.
