Study of temperature and wetness climate of the sedge-grass littoral during the vegetation season
RANDLOVÁ, Monika
Work is focused on studying thermaly-hygric clime sedge overgrowth concerning to his produce parametres and cubic heterogeneity. In construed baccalaureate work i focused on relation of production above-ground biomass slim sedge (Carex acuta L.), with dampness and thermal clime. Slim sedge (Carex acuta L.) is dominant plant in flood part of damp grass fields. Work lie in destructive following overhead biomass along vegetative season. Highest performance live above-ground biomass was analysed in July 1820 g × m-2, but as compared to next takings to be almost constant, in August was analysed 1670 g ×m-2 and in September be signed growth of live above-ground biomass on 1789 g ×m-2. Dry matter overhead biomass decrease with toward the end of vegetative season. In July value of weight dry matter come to 801 g, in August 676,6g and in September were to be signed lowest value 530 g. Weight measured in September was considerably effected downstream that the persisted from second half of August. With those values relate and diminishing value of LAI that the reached values in July 2,44 m2/m2, in August 1,24 m2/m2 and in September 0,59 m2/m2. Work primary lie it measuring thermal and hygric values. Temperature and dampness differ in growth and above growth. Temperature in growth reached lower values than above growth with whereby bears measured higher values dampness in growth. Baccalaureate work was processed in terms of experimental intention agricultural faculty MSM 600*7*665806 ? permanent tenable management techniques of agricultural economy in foothills and mountain regions focused on making harmony between produce and non-produce use".
The quality of wheat for food and feeding
MACHOVCOVÁ, Dana
The quality of wheat meant both for food industry and for feeding is evaluated with all deliveries from co-operative farms, concerns and private farmers every year. Factors which can influence quality of grain, criteria for evaluation of the wheat grain quality, their practical use in working conditions of the concern ZZN Pelhřimov (former Grana, a.s.) detached post Záhoří and results of accomplished tests compared with statewide average were described. Average values of the wheat in 2007 - 2010 demonstrated variability in each characteristics both in the chosen concern and in statewide average. Weather conditions influenced the quality of most parameters. Considerable difference in the quality of grain could be found with particular distributors. The proper agricultural engineering and good seed corn are essential preconditions of first-rate production.
The comparison of several types of microclimates in enclosed places of livestock production
KORÁL, Michal
The thesis is focused on the comparison of several types of microclimates in enclosed places of livestock production, aimed at beef-raising. The goal is a making the comparison of final results of microclimate elements at two sorts of stabling. Stanchion housing versus opened housing.
Factors determining soil respiration rate in herbaceous wetland ecosystem
STARÁ, Alžběta
Annotation: Soil respiration represents an important flow of CO2 between atmosphere and soil. Carbon bounded in the process of photosynthesis may be fixed in soil, but also may be released back to atmosphere in the form of CO2. An accurate evaluation of global carbon balance is a key for the estimation of future development of atmospheric concentration of CO2 and prediction of climate changes. The soil respiration of selected wetland biotopes with graminoid vegetation was studied in relation to concentration of soil carbon, nutrient availability, soil moisture and soil temperature during the vegetation season 2008. The observed wetlands included a locality located near the village of Hamr with mineral soil and the nature reserve Záblatské meadows with organic soil. Soil respiration was measured as CO2 release from soil with the use of the equipment LiCor 6400 with soil chamber. The influence of fertilizer application on CO2 release was not proved for either locality. A relationship between soil respiration and soil moisture was found on Záblatské meadows, where the CO2 release declined with increasing soil moisture.
Influence changes weather and microclimate stable on milk efficiency dairycows in choice company.
HÁNA, Bohumil
The topic of my bachelor´s thesis consists in the evaluation of the impact of the changes in the weather and the stable microclimate on the milk efficiency of dairy cattle. The measurement of the basic external and microclimatic elements is executed at the selected plant of the company Pivkovice a.s., seated in Netonice. The evaluation of these elements´ impact on the milk efficiency of dairy cattle is subsequently carried out.
EFFECT OF ENVIRONMENT ON THE BEHAVIOR OF CALVES
HAISOVÁ, Dita
The aim of this work was monitored by video recordings made in the ZD Krásná Hora nad Vltavou, 6 different types of outdoor hutches and individual one on the basis of different behavior of calves to evaluate the suitability of different types either for breeding dairy calves in the period. Investigations were carried out in winter and summer, was used in recording AVI Windows Media Player with a length of 1-minute intervals. Heifers of Czech Spotted cattle were monitored. Length of stay of individual calves in outdoor hutches was from 83-87 days. The purpose of monitoring was to evaluate the length of stay of calves within each individual outdoor hutches and length of stay outside. In each hut were installed sensors, reported the values of internal temperature and relative humidity at intervals of 15 minutes. Given that microclimate should be in different climatic conditions to create an optimal environment for the calves, the criteria have been satisfied welfare length of stay inside the shed. The average outdoor temperature during the reporting period of the winter fell to -2.54° C. In this period, the individual VIB measured average indoor temperature of -0.04 ° C to -1.43 ° C. During the follow up period was recorded in summer average daily temperature of 19.79 ° C. Summer temperatures average in each of the VIB was 21.14 ° C - 22.27 ° C. These data were no statistically significant temperature differences (P ? 0.05) between the VIB in winter and in summer. The average relative humidity in the microclimate in the winter of VIB reached values ranging from 79.57% to 86.76% in summer from 59.59% to 63.55%. In the winter when evaluating indicators of microclimatic relative humidity between VIB was a statistically significant difference P?0.05 (1:2, 2:3, 2:4, 2:5, 2:6). In winter, the length of stay within the VIB calves ranged from 73.96% - 88.96% of the reference time. Differences between the lengths of stay within the VIB calves were statistically significant (P?0.05 to P?0.001). Over the summer period, length of residence either within the calves ranged from 65.68% - 80.85% of the reference time. Differences between the lengths of stay during the summer period were significant (P?0.05 to P?0.001). Total for the period was the top-rated wooden shed ZD Krasna Hora nad Vltavou.
Effect of stable microclimate on the welfare of livestock in a selected company.
HÁNA, Bohumil
The theme of my thesis is focused on assessing the impact of changes in the microclimate of the stable welfare of dairy cows. Measurement was done in selected company called VOD Hrádek in it´s stable VKK Tedražice by measuring the basic external features and microclimate and it all was resulting in assessment of their impact on welfare of dairy cows.

KALÍŠEK, Jan
The survey aims to evaluate the microclimate in stables, belonging to a National stud farm in Kladruby nad Labem, depending on outdoor climate.
Evaluation microclimate in dairy farming in chosen enterprise and proposal for improvement.
VACUŠKA, Josef
The substance of this bachelor work is mainly to evaluate microclimate in dairy farming and to suggest ways for it{\crq}s improvement. Dairy farm is located in chosen enterprise. The work describes characteristics of temperature, moisture, wind{\crq}s speed in chosen stable and it{\crq}s impact on animals. Next step was to propose the ways which could that microclimate adjust on values, in which animals are felling well.
THE PASS JUDGMENT ON THE CLOSEC MICROCLIMATE SPACES LIVESTOCK PRODUCTION
KORÁL, Michal
