From fast-growing plants, Miscanthus is a promising alternative energy source exploitable at regional level. The climatic conditions in the region also have a significant impact on the biomass production and also on the economic efficiency. The aim of the paper was to evaluate the influence of selected climatic parameters on the total production of the above-ground biomass of two Miscanthus genotypes in the Nitra region in the Slovak republic for the years 2015-2018. The method of monitoring climatic parameters and the destructive method of determining the biomass yield of the above-ground organs were used. Based on an analysis of the total Miscanthus biomass production, it is possible to confirm a statistically significant difference in production in the monitored years. The influence of air temperature fluctuations in the spring months and the lack of precipitation at the time of the cumulation of shoots growth on the overall biomass production were also confirmed. The year 2015 was warm and dry, the year 2016 was cooler, but with enough precipitation. The year 2017 was cold with enough precipitation and the year 2018 was warm and humid. The climatic parameters affected a total biomass production in mentioned years. [ABSTRACT FROM AUTHOR]

This paper evaluates the abnormalities in monthly, half-year and annual rainfall totals in the Western Tatras Mts for the period 1994 to 2013, issuing from the values recorded at the precipitation stations Bobrovec situated at 632 m a.s.l., Zuberec at 763 m a.s.l. and Červenec with an elevation of 1,500 m a.s. l. These stations have also different exposures as for the dominant wind flow: Bobrovec is situated on the leeward side, Zuberec on the windward side and Červenec in the summit part of this mountain range. These three stations were chosen to study the influence of exposition and altitude on the precipitation amount and distribution. These precipitation stations do not yet have their precipitation normal (30-year-observation series). Thus the abnormalities of precipitation totals were assessed by comparing our annual sums with long-term average precipitation values calculated based on the monthly sums of vertical precipitation provided by the Slovak Hydrometeorological Institute (stations Bobrovec, Zuberec) and the Institute of Hydrology Slovak Academy of Sciences (station Červenec). At the Zuberec precipitation station, we recorded an average rainfall total of 998 mm, whereas at Bobrovec station of 735 mm. Station Červenec has an average rainfall total of 1471 mm. For each station, the course of percentage difference from the long-term average annual total was represented graphically. [ABSTRACT FROM AUTHOR]
