Study of Trifolium angulatum phytomass in Karcag
31-36Views:423Our studies were conducted at the Hungarian University of Agricultural and Life Sciences in Karcag, where in 2023, due to favourable precipitation and temperature conditions, we had the opportunity to study the phytomass yields of a massively reproducing annual Trifolium species in a saline soil condition. Yield measurements (green yield, hay yield, crude protein yield, dry matter yield) showed that in all cases higher yields were measured in the Trifolium angulatum-covered grassland than in the control grassland, and statistical analysis showed a close correlation in all cases. Through our studies, we aimed to provide new data on the specific floristic events in environmentally managed grassland in the Pannonian Basin from a farmer's perspective.

Reed hay as a delicacy
3-8Views:372Comparison of yield and nutritional values of Phragmites communis and Festuca pseudovina main crops was carried out in 2022 in Karcag, in a meadow-solonyec soil condition.
In terms of yield indicators, the values for cane were demonstrably higher than for the concurrently mown lean bunchgrass in flowering phenophase.
The results of the nutrient analysis showed higher N, P, K, Zn and Mn contents in the cane than in the lean samples. However, in terms of Ca, Mg, Na, Cu and Fe contents, lean chenkase samples showed higher values than reed samples.
Of course, our results can only be considered as a first step in the refinement of the value metrics for perspective alternative fibre feeds -
Impact of mole migration on soil factor indicators of extensive grassland
25-29Views:415We investigated the effects of mole walks in extensive grassland soil, focusing on changes in soil factor indicators, 3-3 times per year, in 2022-2023, in Karcag. Based on our results, we found that the drier year 2022 had verifiably higher carbon emission values, only on an annual average, than the wetter year 2023. We found no verifiable differences in soil temperature and soil moisture conditions. Based on our data, it can be concluded that the mammal of choice for the year 2023, the mole, does not have a significant impact on the carbon dioxide emissions of the grassland soil. Further studies in other habitat conditions are definitely warranted.

Possibility of testing italian ryegrass (Lolium multiflorum Lam.) with MALDI TOF-TOF MS
7-10Views:461Lolium multiflorum seeds were tested by MALDI TOF-TOF MS using 3 extraction solvents (NaCL neutral, NaCl acid, propanol). Our aim is to develop a method for grass seed testing. Among the 3 methods, only the propanol extraction agent was able to obtain a noise-free spectrum, revealing the m/z values of the reserve protein in the italian ryegrass seed.

Follow-up of the cover value of grassland plants with different light demand in different types of grassland
17-21Views:408Changes in the cover value of grassland species over a four-year period were investigated in terms of light requirements for grassland species under different management regimes (mowing, mulching, meadow management, overgrazing). The highest cover values of light-demanding grassland plants (Trifolium sp., Achillea sp., Plantago sp.), which are ecologically and economically valuable and typical for extensive grassland with a soil condition of Solonyec, managed by the MATE Research Institute Karcag, were measured under mowing and meadow utilization. The lowest cover values of light-demanding butterfly-flowering species were found in treatments covered with leafy phytomass and overgrazed with sheep. In the overgrazing treatment, we observed invasive emergence of the light-hungry Hordeum murinum, a potential threat to sheep welfare.

Effects of gradation of common vole (Microtus arvalis) on plant composition and carbon dioxide emissions of semi-natural grassland associations
11-15Views:537We investigated the effects of the 2023 Hungarian pococodegradation on the autumn and spring aspects of a semi-natural grassland association on saline soils. We measured changes in vegetation structure due to the direct phytomass damage of the vole and the uncovered area caused by the large number of tunnels. The cover value of disturbance-tolerant plant species in the vole grassland increased, and so did the degree of degradation. Significantly higher carbon dioxide emissions were measured in the vole-damaged grassland than in the control grassland in autumn and spring. The proven higher activity of microorganisms in the soil with vole tunnels can be explained by the more favourable aerobic conditions of the saline clay soil. Due to the predicted mild winters and drier springs, our lawn management should be prepared for more frequent vole invasions, the effects of which we intended to provide data on.

The effect of wood ash on the structure of plant communities and phytomass yield in a solonetz soil grassland
33-35Views:203As a potential nutrient source, we investigated the effects of wood ash doses (10-20-30 g/m2) on a semi-natural grass community formed on saline clay soil. The impact of the wood ash doses was evident in the structural composition of the vegetation, particularly in the higher cover values of Alopecurus pratensis and Poa pratensis sp. angustifolia, which are capable of achieving greater phytomass. The green yields correspondingly followed these structural changes in the vegetation. Notably, the most favorable economically viable plant community and yield levels were measured at the 20 g/m2 dosage, while values decreased at the 30 g/m2 dosage. Our experiment raised several questions, highlighting the justification for broadening the research.
