  From the point of view of the lawns' current existence, use and their existence for the future, but the tasks, goals and challenges of grassland management have changed, and in line with this, we have carried out surveys and developed and modified a method for fast and efficient application.

  In practice, it is very important to know the quantitative and qualitative characteristics of the forage found in the pasture, as well as the exact economic value of the pasture. The purpose of this study is to present a cheap, fast, reliable and easy-to-apply estimation method.

  We took the previous methods into account and corrected and further developed them with the help of recent lawn management research results. Based on our tests, the corrected Balázs method can be used well to estimate the yield of grasslands and to determine the fodder value of the grassland. This method is cheap and requires no technical background. It also has the advantage, based on experience, that it takes into account the preference of species by animals.

  The data from the cenological survey and the height measurement of the plant stock can be used to estimate the yield, fodder value and economic value. Being a non-destructive method involving minimal trampling, it is also particularly suitable for monitoring the grassland habitat of protected plants and animals. The method is also presented on a sample example, which proves its applicability.

  In Keszthely, the breeding of grass species have several decades long history. Among other things, the aim of the maintenance work of the registered varieties is to preserve the ploidy levels that have been reported in the variety descriptions. Flow cytometry is a fast, modern tool for examining plant DNA content. In our pilot study, we compared the genome size of the four grass species maintained at the MATE Georgikon Campus with the data of known samples of similar ploidy levels published for the given grass species in the international database. Our results showed a high degree of agreement with the theoretically expected values, supporting the applicability of flow cytometry in plant breeding and in variety maintenance.

Later he became an active participant of agricultural research. His main line is the botanical and economical evaluation of grasslands by phytosociological records developed based upon Hurt-Sernander’s method for estimation of the vegetation cover, phytomass and quality (hay value).

  It is commonly known that the red deer population of Somogy County is of excellent quality, due to the good genetic background and habitat conditions. This article tries to point to the changing situation, as a consequence of the forced overharvest and the repeal of the so-called minus-point sanctions for the trophies (which can be evaluated as a too early harvest). The stag stock become markedly younger, the average age of the medal stags is decreasing while the female stock is aged.
