The field experiment was performed on the brown soil with slight-acid to neutral soil reaction and medium content of Nan in locality of Velké Ripňany. Impact of natural drying of soil samples on Nan content in the soil and sunflower seed yields was investigated. The relationship between determined Nan content and production characteristics (achene yields, thousand seed weight), respectively, w ...

The dynamics of root accumulation and root increment of seminatural grassland utilised by three cuts was investigated in the middle Slovakia region (Banská Bystrica, Suchá dolina, elevation 460 m). The amount of root biomass (0-100 mm) was determined in the spring and autumn period, as well as at the three cuts during growing period of the years 1991-1998. The average amount of root system was ...

The aim of this paper was to estimate influence of different pedigree completeness on intensity of inbreeding in reference population of Slovak Arabian Horse. There were used pedigrees of 76 animals, pedigree file contained 866 ancestors. Average values of inbreeding coefficient were estimated from all pedigrees (Fc=3.66%), using only three (F3=0.37%), five (F5=1.70%), ten (F10=3.63%) generati ...

Effect of polymer-coated fertilizer on aboveground and root biomass of strawberry (variety of Clery) was investigated in pot experiment with brownsoil in 2009. In addition, yield of mature strawberry fruits and content of vitamin C in them were determined. There were examined three treatments in the experiment: 1st treatment-unfertilized control, 2nd treatment-application of 1.65 g N per pot i ...

The botanical composition of 4 turfgrass mixtures was evaluated by the method of reduced projective dominance in field conditions on the clay-floam fluvisoil in the Demonstration and research base of the Department of grassland ecosystems and forage crops, SAU in Nitra, during 2007-2009. The seeding species from a mixture were significantly manifested in the early stages of turf development. T ...

Streamsediments are considered a qualitative indicator of the environment from the environmental point of view. According to the methodology used in the study area, the Čaradice stream represents an area that has been permanently threatened by two sorts of contaminants, the physical and the chemical ones as well. The most important is the interaction between the water of the sediments and inap ...

The aim of this study was to monitor the amount of inbreeding and generation interval in the Czech draft horse populations. The inbreed procedure was used for calculations (SAS, 2005). The foals born in the period 1990-2007 and registered as Silesian Noriker (SN-917), Noriker (N-1986), and Czech-Moravian Belgian horse (CMB-2323) were used as the reference populations. The average value of coef ...

The research evaluated direct effect of population structure in breeding programme and influence of selection intensity on increase of inbreeding per generation. The impact of strategy change and intensity of selection, or the change of mating strategy with the aim to minimize increase of inbreeding was analyzed by the Monte Carlo stochastic simulation, according to the existing population str ...

The Old Kladruber horse is an original Czech breed, included among the genetic resources of the Czech Republic. Typical coat colours are grey and black, but different coloured individuals (bays and chestnuts) may also occur. The coat colour in horses is the result of the action and interaction of several different genes. This paper briefly describes basic genes for dark coat colours (black, ba ...

This paper confirms the decreasing trend in the population size of the Slovak Pinzgau cattle, if this tendency continues and the forestallment is absent, the risk status of the breed in Slovakia can increase. The evaluation of the Pinzgau cows and bulls is currently based only on the milk production, despite the dual purpose character of the breed. One possibility of more complex evaluation is ...
