Comparison of the production of fenugreek (Trichonella foenum-graecum) experiments in 2018-2020
11-14Views:102The aim of our study is to compare the results (content values, yield) of fenugreek (Trigonella foenum-graecum L.) experiments in 2018-2020. Fenugreek is an annual herbaceous plant belonging to the legumes (Fabaceae) family. It is a multifunctional crop for use in domestic and farm animal feeds, wild fodder, herbs and spices. During the study period, nutrient supply treatments were applied to increase the production values of the plant. The weed suppressing ability of fenugreek in the post-emergence period (1-3 weeks) is very poor, so we had to use chemical weed control. During the experiment, the T. foenum-graecum stock was irrigated. The plant was harvested 80-90 days after sowing. The study was carried out in Kecskemét in 2018-2019, at the Demonstration Garden of John von Neumann University, Faculty of Horticulture and Rural Development. The 2020 experiment was set up at the University of Szeged, Faculty of Agriculture.

Effects of ceasing mowing and grazing on the vegetation of wet grasslands of Badacsonytördemic
23-32Views:146During the work we examined the vegetation of a wet area near Badacsonytördemic. The grassland has been mowed and grazed intensively by Hungarian grey cattle until 2010, and it was abandoned afterwards. We surveyed three sample areas: the continuously grazed pasture, the mowed grassland and the additional pasture, which was grazed for one month each year.
Records were made in June 2010 and 2020. We utilized 4×4 m quadrats, and gave the cover of species in percent. Relative nitrogen values (NB), soil moisture values (WB), Social Behaviour Types according to Borhidi, nature conservation values (TVK) according to Simon were also used.
Based on the results, the vegetation of the area degraded greatly in ten years, its diverse nature disappeared, weeds and invasive species became dominant and species with good foraging value declined. No aggressive competitors were found in 2007, but Solidago gigantea appeared with great cover by 2020. In addition, many weed species appeared, and the ones which were already present in 2010, have increased their cover. Cirsium arvense was a newly appearing weed. Dead biomass also increased greatly.
To avoid further degradation, we suggest to reintroduce the management to these areas again. To set back weeds and invasive species, regular mowing would be efficient. It would be important to carefully set the date of mowing so that it prevents the spreading of seeds. Mowed plants must be removed from the area as soon as possible. -
Recovery of grasslands in former croplands using the combination of seed sowing and hay transfer
5-11Views:54In accordance with general trends in agricultural and natureőconservation practice in Europe, grassland restoration and traditional grassland management has gained increased importance in Hungary. In grassland restoration using of low rates of seed (less than 30kg/ha) and hay cover is suggested. In the present paper the effect of hay cover combined with low rate of seed (25 kg/ha) is studied in early grassland recovery. We aimed at to answer the question whether or not the speed of grassland recovery can be increased with a combined use of seed sowing and hay cover. The establishment of Festuca species was favoured by hay cover combined whit seed sowing. The emergence of shortlived weeds was significantly lower on most of the fields treated with hay cover and seed sowing. The species richness and diversity of early weeds did not differ significantly in fields sown only and fields treated both with seed sowing and hay cover. Our results suggest that the combination of seed sowing and hay cover is successful in fields, where high rate of weed invasion is possible, thus intensive post-restoration management is necessary.

Impact of a change of use on extensive grassland yields
29-34Views:84The impact of converting overgrazed extensive grassland to mowing was investigated in Karcag between 2017 and 2020. At the beginning of the experiment, the plant composition of the overgrazed grassland community, which had been overgrazed for 3 years, showed a high and continuously increasing cover of unconditionally weeds avoided by sheep, which presented clearly higher quantitative indicators in terms of yield values. However, in the grassland communities that were converted to mowing, the cover of unconditioned weeds decreased steadily at the end of the experimental period and the cover value of grassland components valuable for animals increased, thus stopping degradation and recultivation by conversion was successful.

Fajösszetétel és diverzitás változás kiskunsági száraz és nedves fekvésű legelőkön
15-30Views:147Investigations were carried out in wet – next to Tatárszentgyörgy, and dry grass pasture – next to Bugac, both located in Kiskunság, in the central region of Carpathian Basin. Recordings were taken every June of 2007, 2008, 2009 and 2010 from Tatárszentgyörgy – where cattle were grazed, and 1997, 2005 and 2010 from Bugac, where cattle and sheep were grazed. Coenological recordings were taken in three zones. The first zone ("A" zone) located 0-50 m near the stable, second zone ("B" zone) located 50-150 m from the stable, while the third zone ("C" zone) located farther then 150m from the stable. Analyses of ecological and environmental factors were based on Borhidi’s relative ecological indicators. Life form analyses were performed by Pignatti life form types. For statistical evaluation, R software was applied. Shannon diversity. Based on our results for both dry and wet grasslands, quadrates of "A" zone were well isolated from the rest of the zones. Overgrazing, which involves considerable trampling, vanishes differences among vegetations, thereby promotes weed and disturbance tolerant rich vegetation. The lowest species number and diversity could be found here. Recordings for "B" and "C" zones separated from recordings of "A" zone, furthermore, quadrates of wet and dry grasslands formed separate groups. From recordings of "B" and "C", zone perennial grass species (H caesp) and the emerging perennial (H wrap) species multiplied and these species were the indicators of grazing. The greatest lifeform richment were presented among "B" zone recordings. The amount of intensive grazing indicator species, such as creeping perennials (Hrep) was significant in "B" zone recordings of Tatárszentgyörgy. Grazing stabilised the local vegetation, but increased the ratio of disturbance tolerant species, which was confirmed by conservation evaluation. This is due to the conversion of grassland types, the transition from free grazing to switch grazing, which resulted in an intensive involvement of the more distant "C" zone as well. "A" zones fully converted; they changed into fully reliefs. Further located sample area vegetations were not homogenised by grazing and even helped the preservation of characteristic species. In the aspect of environmental protection, vigorous grazing led to a more valuable vegetation in "B" zone in an arid grassland (Bugac). According to the sample area, wet grasslands from the sandy areas of Kiskunság, preserve nature protection values and grass composition better moving away from stables, due to less grazing pressure. Drier backgrounds tolerate stronger grazing pressure (Bugac), while in case of wetter areas (Tatárszentgyörgy) – considering sustainability – grazing should be carried out with caution.

Comparison of vegetation of Hungarian Grey Cattle and Domestic water buffalo pastures in a sample area of the Danube-Tisza Interfluve
15-31Views:64We made a coenological study on the Kelemen-szék in the Kiskunság National Park. The coenological studies were carried out twice, in 2014 and 2015. During these two surveys, we examined in total 90 quadrats of mixed grazed and fenced control areas by domestic water buffalo and Hungarian Grey Cattle. Due to the size and heterogeneity of the studied area, we intended to investigate small homogeneous areas and respective control areas. Coenological surveys were done on lower and higher lying pastures, saline soil areas and loess areas.
The studied areas were assessed based on the Borhidi relative plant ecological indicators NB (relative nitrogen values) and WB (relative groundwater and soil moisture indicator values). The distribution of nature conservation value categories (TVK) and social behavior types (SzMT) were used to assess the areas. Cluster analysis and detrended correspondence analysis (DCA) were used to evaluate the data.
The data were assessed based on both habitat condition in terms of naturalness condition. On the other hand, relative ecological indicators of the occurred species. Our objectives were to provide a detailed description of the vegetation composition of the study areas, to assess the changes in grassland composition and their conservation impacts as a result of grazing and its abandonment, to assess the impact of grazing on the occurrence of protected species and weed species, and to assess grazing as a conservation habitat management practice.
The examination of the species composition showed that the loess and saline soil areas grazed by domestic water buffalos and Hungarian Grey Cattle provided a better composition of grassland in terms of natural condition compared to the control areas. In the dense and tall Puccinellia swards vegetation type, grazing requires more attention, because it is more vulnerable to grazing, has fewer species and is more damageable.

Az avar rövid életű keresztesvirágú (Brassicaceae) gyomfajok csírázásra gyakorolt hatása
3-8Views:41Recruitment by seeds is essential both in vegetation dynamics and in supporting grassland biodiversity. Recruitment by seeds is feasible in suitable microsites from the seed rain and/or by establishment from persistent soil seed banks. Cessation of grassland management by grazing or mowing results in litter accumulation, which leads to the decrease of species richness by the decreased availability of open patches. Low amounts of litter are often beneficial, while high amounts of litter are detrimental for seed germination and seedling establishment of short-lived species. However, the magnitude of these effects on germination and seedling establishment in relation to litter and seed attributes are scarcely studied. This motivated us to design an indoor experiment to explore the effects of litter on seedling establishment. We germinated six short-lived Brassicaceae species (Arabidopsis thaliana, Capsella bursa-pastoris, Descurainia sophia, Erophila verna, Lepidium campestre, and Lepidium perfoliatum) with different seed mass under increasing litter cover. We found that both seed mass and litter had significant effect on germination and establishment of the sown species. Small-seeded species were significantly negatively affected by the 300 g/m2 and/or 600 g/m2 litter layers. No negative litter effect was detected for species with high seed masses (Lepidium spp.). No overall significant positive litter effect was found, although for most of the species; total seedling numbers was not the highest at the “bare soil” pots. Our results suggest that the effects of litter accumulation on the germination and establishment of short-lived species are less feasible in case of large-seeded species than on small-seeded ones.

Kaszálás felhagyás hatása helyreállított szikes és löszgyepek vegetációjára
21-29Views:68Grasslands recovered by sowing of low diversity seed mixtures are frequently managed by mowing. However only a few studies focused on the direct effects of post-restoration mowing on recovered grassland vegetation. In this study we followed vegetation changes in 13 recovered grasslands, in 5×5-m-sized exclosures with continuous and ceased mowing in Hortobágy, East-Hungary. We asked the following study questions:
(i) What are the effects of cessation of mowing on the vegetation structure of recovered grasslands?
(ii) What are the effects of cessation of mowing on the abundance of sown grasses, target and weed species?
(iii) Is yearly mowing an appropriate management for the maintenance of recovered grasslands?
Our results showed that the cessation of mowing caused litter accumulation, decrease in total cover and decrease in the cover of sown grasses compared to the continuously mown exclosures. The cover of perennial weeds was significantly higher in unmown exclosures compared to the mown ones. The species composition in mown exclosures remained more similar to reference grasslands than to the unmown ones. Our results suggest that without a regular post-restoration mowing the favourable stage of recovered grasslands can be rapidly vanished caused by litter accumulation and/or by the expansion of undesirable weedy species. We also stress that yearly mowing is solely enough to maintain grasslands recovered by low-diversity seed sowing, but cannot be considered to be enough to recover target vegetation composition.

The Role of Grassland in EU Soil Protection Strategy
3-15Views:63The three most important life quality criteria are: healthy and good-quality food, clean water and pleasant environment. All three are closely related to the sustainable management of natural resources; conservation of soil and water resources; rational land use and landscape preservation. Soils are conditionally renewable natural resources, consequently, their rational use, conservation, and the maintenance of their multipurpose functionality have particular significance both in the national economy and environment protection. The main soil functions are: integrator (transformer) of other natural resources; most important media for biomass production; storage of heat, water, nutrients, pollutants; buffer of various natural and human-induced stresses; huge natural filter (preventing groundwater pollution); detoxication media of various harmful substances; habitat for soil biota, gene-reservoir, media of biodiversity; conservator of the natural and human heritage.
The maintenance of these functions is the key-element of sustainable development on all levels of the decision-making process: Globe → continent → region → country → subregion → settlement → farm → field. The EU Strategy for soil protection focuses attention on 8 environmental threats, for their prevention, elimination or moderation:
– water and wind erosion;
– decrease in organic matter resources;
– compaction and structure destruction;
– soil sealing;
– the increasing frequency, duration and degree of extreme moisture events: flood, waterlogging – drought;
– point and non-point (diffuse) soil pollution;
– salinization/alkalization/sodification;
– decline in biodiversity (decreasing number and activity of soil organisms, narrowing their species spectra).
The EU-conform Soil Conservation Strategy of Hungary was elaborated during the last decades on the basis of long-term soil survey, soil analyses, soil mapping and soil monitoring activities. It comprises three main tasks:
– the prevention, elimination or moderation of soil degradation processes;
– the reduction of the unfavourable economic, ecological, environmental and social consequences of extreme moisture regimes;
– the control of the biogeochemical cycle of elements: optimum nutrient supply of plants; prevention of harmful soil pollution and contamination of the „food chain”.
Grassland management has to play a significant role in these actions. In addition to fodder production, rational grassland management can considerably contribute to the storage, buffer, filter and gene-reservoir functions of soil, to the improvement of soil moisture regime, to the moderation of extreme moisture conditions, and to the reduction of soil losses caused by water or wind erosion. In spite of these favourable impacts grasslands (covering about 12% of Hungary) have never been in the focus of Hungarian agriculture.
Grasslands were always restricted to marginal lands (sands, salt affected soils, peatlands, floddplains) with low and risky (highly weather-dependent) biomass production and low animal carrying capacity. Relatively productive grasslands were upturned for corn in large hilly areas (resulting serious erosion losses and landscape deterioration); the huge floodplain grasslands were used for other agricultural crops after flood control and river regulation; peatland grasslands were also considerably reduced by the drainage of these areas and used (not always successfully and efficiently) for arable crops. Huge areas became seriously degraded wastelands or „weedlnds” due to irregular grazing, lack of weed control, plant nutrition, water management. Under improper management not only the biomass production decreased considerably but the soil conservation functions of grassland were also deteriorated, sometimes dramatically. The poor and degraded grassland vegetation were not able to prevent (or at least moderate) water erosion losses in hilly areas, wind erosion losses in the dry sand regions or „over-drained” ameliorated peatlands, and even their gene-reservoir functions are sometimes threatened seriously.
Rational grassland management is an important element of both the European and Hungarian Soil Conservation Strategy. Its scientific bases are well-known. The details have to be determined by further research and scientific programs. The existing knowledge should be broadcast using all available information channels: teaching and education on various levels; demonstrations; media programs, etc. A proper system of stimulating economy regulations should be developed and formulated in various-level legal documents. But first of all an environment-friendly moral must be developed accepting the concept of sustainable grassland management.

Homoki gyepek spontán regenerációja kiskunsági parlagokon
5-12Views:42Bár a spontán szekunder szukcessziós folyamatok vizsgálata kiemelt téma az ökológiában, mégis kevés publikáció vizsgálja a módszer alkalmazhatóságát a gyeprekonstrukcióban. Jelen vizsgálatban, kiskunsági homoki parlagokon gyepek spontán vegetációfejlődését tér-idő-helyettesítéses módszerrel vizsgálva az alábbi kérdésekre kerestük a választ:
Hogyan változik a különböző funkcionális csoportok aránya a szukcesszió során?
Milyen célfajok települnek be sikeresen a parlagokra?
Megadható-e a spontán gyepregeneráció sebessége és értékelhető-e a sikeressége?
A Kiskunságban összesen 12 homoki parlagot vizsgáltunk. A parlagokat három korcsoportba soroltuk:
10 év alatti (fiatal)
10-20 éves (középkorú)
20-40 éves (idős) parlagok.
Korcsoportonként négy parlag növényzetét mértük fel. Referenciának három nyílt és három zárt homokpuszta gyepet választottunk. A növényfajok százalékos borításbecslését öt darab 2×2 m nagyságú kvadrátban végeztük egy kora májusi és késő júniusi időpontban, 2012-ben. Kimutattuk, hogy a szukcesszió folyamán az évelő lágyszárúak borítása növekedett, míg a rövidéletű fajok borítása csökkent. Az invazív fajok borítása szignifikánsan nagyobb volt a fiatal parlagokon, mint az idősebb korcsoportokban. A célfajok többsége már a fiatal és középkorú parlagokon is megtelepedett kisebb borításértékekkel, de szignifikánsan nagyobb borításuk az idősebb parlagokon volt. Megállapíthatjuk, hogy a kiskunsági homoki parlagok esetében viszonylag gyors és sikeres spontán gyepesedésre számíthatunk, a homoki gyepek fajkészlete már a szukcesszió első 10-20 évében regenerálódhat. Számos célfaj spontán betelepülése azonban még a rendelkezésre álló magforrások mellett is csak korlátozott. Ilyen esetben a célfajok megtelepedéséhez célzott propagulumbevitelre is szükség lehet. A spontán szukcesszió akkor lehet a legsikeresebb, amikor a célfajok már a szukcesszió első néhány évében megtelepednek a felhagyott szántókon.

Botanical and grassland investigations in a pasture grazed by Hungarian grey catte in Badacsonytördemic in 2008
73-78Views:62Sample areas can be found in the Tapolcai Basins. Phytosociological samples were collected: 32 ha grassland stand with low intensity grazing (under-grazed pasture), 38 ha overgrazed pasture, 34 ha meadow (hayfield) and the stand where animals drank. The areas were suitable for following up the changes of vegetation and production during the grazing season of the year. 5 replicates of 2×2 m phytosociological samples plots were examined on each grasslands according to the Braun- Blanquet method (1964) in April, May, June, August and September 2008. 118 Hungarian Grey Cattle were grazed on the pastures. 14 species were common in each saple areas, wich are dominant species of natural grassland associations (Agrostis stolonifera, Festuca arundinacea, Deschampsia aespitose) in the region. The overgrazed pasture had only low nutritive value and contained high number of weed species. About one month per year grazing time in the undergrazed area was not enough to achieve a better state of species diversity, although the forage production of the area remained high. The number of species and the 32 ha grassland was high (58) weeds was due to the high number of weeds, however the nutritive value of this grassland was poor. The species number of the hayfield was lower (31) than and grassland, however species composition was better and the nutritive was higher. It seemed that management was suitable and the hayfield.

Comparative investigations of biomass composition in differently managed grasslands of the Balaton Uplands National Park, Hungary
49-56.Views:77Phytosociological and biomass samples were collected in two territories of the Balaton Uplands National Park (Hungary) dominated by grassland habitats. Samples in the Tihany Peninsula had been taken in a pasture of Hungarian Grey Cattle. Studies were broadened to four areas of the Tapolcai Basin, Badacsonytördemic (undergrazed and overgrazed pastures, hayfield, control area). The areas were suitable for following up the changes of vegetation and production in every grazing season of a year. We evaluated the changes of species composition and ground cover, the measure of possible regeneration or degradation, and the changes of these factors from the viewpoint of feeding value. Covering rates of the grassland associations have doubled and species composition has improved in the Tihany Peninsula, however, forage value has not increased, due to the change in land use in favour of the natural area that is converting into grazing field. In case of the Taplocai Basin, low number of species (20 to 30) was detected in the undergrazed pasture and the control area. About one month per year grazing time in the undergrazed area was not enough to achieve a better state for species diversity, and the amount of forage remained high. The overgrazed pasture carries a low forage value and contains a high number of weed species, despite the spectacularly high total number of plant species (38 to 39), consequently, grazing pressure has to be decreased. Although the number of species is lower in the hayfield (26 to 28), species composition and ability for forage supply is much better, showing that the proper management of the area is taken here.

The effects of fertilization on a 6 years old established grassland
19-30Views:42The effect of different N, P and K supply levels and their combinations were examined in the 33rd year of a long-term fertilization experiment on the yield and mineral element content of a 6 years old established all-grass sward in 2006, with seed mixture of eight grass species. The trial was established on a calcareous chernozem soil. The soil of the growing site contained around 3% humus, 5% CaCO3, 20-22% clay in the ploughed layer and was originally moderately well supplied with available K, Mg, Mn and Cu and poorly supplied with P and Zn. The trial included 4N×4P×4K=64 treatments in 2 replications, giving a total of 128 plots. The fertilizers applied were Ca-ammonium nitrate, super phosphate and potassium chloride. The groundwater table was at a depth of 13-15 m and the area was prone to drought. The 1st cut was made on 08th June, the 2nd one on 11th September. During the vegetation period of 8.5 months in 2006, the site had a total of 397 mm precipitation. The lay-out, method and main results of the trial were published earlier (Kádár, 2004, 2008; Kádár és Győri, 2004, 2005). Main conclusions of this study are as follows:
- The 1st cut hay yield gave the ¾ of the total yield. Highest yields were reached with the 200 kg/ha/year N-fertilization on soil well supplied with P (Ammonium-lactate soluble P2O5: 214 mg/kg). The yield of NP control plots increased from 1.5 t/ha to about 7.5 t/ha as a function of the N×P positive interaction. The rising P supply alone was not able to enhance the yield, however the N fertilization gave 3.5 t/ha hay surplus even in the P-control treatments. N and P fertilization together resulted in 6.0-6.5 t/ha yield surpluses. The effect of K fertilization also reached 1 t/ha on the NP levels where the ammonium-lactate soluble K2O content fell below 150 mg/kg.
- The 2nd cut hay gave 0.5 t/ha on the NP-control plots unfertilized for 33 years, and 2.5 t/ha on the 300 kg/ha/year N treatment with well P-supply. The two cuts together resulted in yield levels between 2-10 t/ha according to the extreme NPK supply. In this year, with relatively good amount of precipitation, the hay yield surpluses for 1 kg N were 47-33-23 kg for the 100-200-300 kg/ha treatments.
- The C/N ratio of the 1st cut was narrowed (from 52 to 24) with N-supply and the concentration of N as well as most of the cations increased with the rising N fertilization. In the low yield of the 2nd cut the elements, metals were accumulated. The P, S and Sr were enriched in hay as a result of rising P supply, as superphosphate contains these elements. Antagonistic effect of P predominated in the uptake of other elements, metals (Na, Zn, Cu, Mo, Cr, Co). K content of the hay was lifting while other elements were dropping with the increasing K fertilization partly as a result of dilution effect (N, P, S) and mainly because of cation antagonism (Ca, Mg, Na, Sr). K-B antagonism also appeared.
- The N×K interactions resulted in 2-fold Sr and 18-22 fold Na content changes while N×P caused 18-22 fold changes in Mo contents, especially at the 2nd cut. As it can be seen, fertilization can have drastical effects on soil and crops. The induced element deficiencies or oversupplies can lead to diseases, disturbances in the metabolism of animals, so the soil and fodder analyses are necessary.
- Considering the leaf diagnostical data, the satisfactory level will be at 200 kg/ha/year N supply and 150 mg/kg ammonium-lactate soluble P2O5 and K2O level or above. The S, Ca, Mg, Fe, Mn supply were satisfactory even at the control plots, while the Zn, Cu and B levels showed deficiency. The P/Zn and K/B ratios became adversely wider in some treatments, as well as the narrowing of the Cu/Mo ratio denotes Cu deficiency and Mo oversupply.
- The amount of elements uptaken by hay as a sum of the two cuts and as a function of the supply/yield varied between the following values in kg/ha: 17-163 N; 36-122 K; 9-48 Ca; 6-17 P; 4-15 S; 3-14 Mg; 0,3-8,0 Na; 0,2-1,4 Fe; 0,2-0,9 Al and Mn. The other elements showed the following uptake: Zn 33-194, Sr 28-141, Ba 5-46, Cu 5-39, B 5-26, Mo 3-6 g/ha.
- The botanical composition was drastically modified by the aging of the grass and the nutrient supply. Only three species remained out of the eight sown species and one immigrated. Coverage of the tall fescue was between 21-70% according to the N×P supply and 44% as average; coverage of cocksfoot varied between 4-24% depending on the treatment and 18% as an average; coverage of crested wheatgrass was between 0-28% and 9% as an average; the immigrant smooth brome covered 0-24% and 9% as an average; Weed cover was 3-4% as an average at the 1st cut. Weeds thrived mainly on those areas where the grass thinned away (extreme NP-deficiency or oversupply). The total plant coverage on NP-deficient soil was about 50%, while on treatments well supplied with NP it amounted 95-97%.

Degradation degree evolution under different grassland management
35-44Views:96The objective of this manuscript is to clarify the changes in vegetation structure of an extensively managed grassland association under different land use practices. In the grasslands of the Hungarian Great Plain, the westernmost part of the Eurasian steppe, the largely decreasing grazing livestock numbers and the almost disappearing pastoral grazing make the topic very topical. We analysed the last 4 years of the study period 2009-2020 and found that the lowest degradation rates were measured in the meadow utilisation management, with values ranging from 0.277-0.463 in the 11th year of the experiment. And the highest degradation values were measured in the treatment with the overgrazing mode, with degradation degrees 3.43-5.0 in the 11th year of the experiment. In the treatment demonstrating the effect of overgrazing, we measured a high increase in the cover value of the weed Hordenum murinum, which is very dangerous for sheep, between 2017 and 2020, with an average of 107.6%.

Parasite control with Red Chicory extract
27-29.Views:141Authors conducted studies in 2021 at the sheep farm of Karcag Research Institute. Searching for methodologies to reduce endoparasitosis. Traditional medical application of weed roots, with a focus on tannin and inulin content were tested. Extracts from Cichorium intybus and Cichorium intybus var. foliosum were made and administered to infected ewes. Strongylus sp. eggs significantly reduced after treatment due to inulin and tannin content. Further experiments should be reveal whether dried or diluted extracts are more efficient.
