Possibility of testing italian ryegrass (Lolium multiflorum Lam.) with MALDI TOF-TOF MS
7-10Views:355Lolium 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.

Conflicts between farming and nature reservation in grassland managements
31-34Views:187In the last few years important changes occurred in the grassland usage and in the grassland framing, which changes revised the farming circumstances of the grassland farmers. These changes come to the fore leading in the environment friendly, agricultural environment friendly programs, and drove farmers into a corner. The unfavorable economic conditions impressed the whole agriculture, because the grass hay user ruminant stock depressed drastically, farms with small animal stock and the herds ended countryside. The economic process did not serve animal husbandry recovery. Farmers see way out for the grassland sector, but on the marked factors we saw the impresses of the negative effects. We say this because they marked complementary seeding and reseeding as primary factors. Aims of the agricultural environment protection programs and the farmer’s cost-of-living will generate more conflicts. On these conflicts could ease rethinking the aims of the agricultural environment protecting programs, with lighten the strict directions of the nature conservation provisions and with ecological grassland farming.

The role of sheep grazing in nature reservation
95-100Views:127Economic and social changes in the last two decades reduced the grazing animal systems more or less to the nature reservation areas. The main objective of these grazing systems on these areas is the preservation of natural treasures herited from the past. Beside that, grazing systems have social (employment) and economic (production) roles as well in some areas of the country. In this paper connections between sheep grazing and the maintenance of different grassland associations of Hungary are investigated from the point of nature reservation friendly farming systems. In general sheep grazing have more positive effects on nature reservation grasslands than its negative effects. It is not difficult to identify the negative effects and to apply proper practical methods avoiding or reducing these effects. Sheep grazing is a proper tool to handle the fragmentation of some of the national grassland areas so it must be kept on as a critical method in the natura friendly farming practices.

Botanical survey of a permanent buffalo pasture
23-29Views:300A botanical survey of a buffalo pasture of Dunaszeg was carried out on 14 May 2024. The study area was a French buffalo meadow (Arrhenatheretum). The results of the cenological survey were evaluated according to Borhidi's Social Behaviour Types and ecological indicator values (water demand, nitrogen demand, light demand), and the degree of degradation of the area was determined. The dominant plant species in the area was French perennial (Arrhenatherum elatius), classified as a disturbance-tolerant species with 36.09% cover. The degree of degradation of the area is close to 1 (DF: 0.99), indicating the degradation of the area due to the constant grazing every day of the year for the 3rd year. In the study area, reducing grazing pressure and occasionally introducing natural seed dispersal into the grassland management technology could be a solution to regenerating the vegetation.
