SENSOR REQUIREMENTS IN PRECISION FARMING (REVIEW)
Authors: H. J. Hellebrand, H. Beuche, K. H. Dammer
Page: 114-119
English / Anglicky:
Since precision farming utilises higher spatial resolution than traditional farming, extensive soil and plant data have to be managed. Therefore, fast measuring techniques are looked for, which provide information on the state of soil and plants. Knowledge on heterogeneity of the fields is essential for precision farming. The heterogeneity can be derived from aerial image evaluation as well as by direct methods like soil mapping, harvest monitoring or different kinds of measurements of biomass distribution. Whereas fast and low cost mapping of soil texture is not solved, there are known principles for fast determination of humus, soil nitrogen, soil density and soil moisture. Advantages and shortages are being discussed. Spectral sensing and spectral imaging of crop in the visible, near infrared and mid infrared (thermal) range show the ability for fast crop surveying. Although intensive research has been performed, and imaging seems to have the best potential for weed and pest recognition, the automatic determination of crop quality is an open question till today.
Key-words: precision farming; heterogeneity; soil nitrogen; soil moisture; weed recognition; thermal imaging.

Vliv dosažené hmotnosti běhounů při zahájení výkrmu na růst a tvorbu svaloviny vykrmovaných prasat.
Authors: R. Stupka, M. Šprysl, J. Čítek
Page: 106-113
English / Anglicky:
The objective of this trial was to determine the attained live weight influence on the growth, fattening capacity and lean meat percentage production in the pigs at the start of finishing. For that purpose 72 pigs of genotype (OLW x BL) x (LW x L) at the average 24,48 kg live weight, and 73 days of age have been tested in the test station during 105 days. All pigs have been divided into 3 groups with respect to achieved live weight at the start of the test. The 1st group was the pigs weighing less 22 kg, the 2nd one was in the range from 22 to 24 kg and the 3th one was over 24kg live weight. The housing of the animals followed the methodology for testing of purebred and hybrid pigs complying with the principle of two pigs per pen (one barrow + one gilt). There were fed ad libitum using self-feeders (Duräumat) by the common feeding mixtures. The lean meat share in live animals was monitored by the help of ultrasound apparatus Sonomark SM100. As far as the results are concerned, pigs of the 1st group achieved at the finish period statistically the lowest (P < 0,01) live weight in comparison with the pigs of the 2nd and 3th groups, simultaneously the lowest average daily weight gain (795 g) in comparison group 2 + 3 (859 or 880 g, resp.). On the other hand the statistically (P < 0,01) highest (2.95 kg) or lowest (2.36 kg) daily feed consumption showed out group 3, respectively 1. The following can be concluded, that body weight in pigs at the start of finishing
- significantly influenced fattening characteristics,
- has no effect on the lean meat percentage activity.
Also the growth intensity has no effect on lean meat percentage in the finishing pigs which represents at the 105 kg or 120 kg, resp., of live weight 57 % or 54 %, resp.
Key-words: pig; weight;

FACULTY OF ECONOMICS AND MANAGEMENT: FACING THE CHALLENGES OF THE THIRD MILLENNIUM (SHORT COMMUNICATION)
Authors: J. Havlíček, J. Hron, I. Tichá
Page: 120-126
English / Anglicky:
The long-term strategy of the university (till 2010) can be created using a decision space based on three main societal/economics drivers a) Changes in knowledge transfer, acquisition, and generation; b) Transfer from European Union society to Pan-European and World-wide society; c) Global implementation of Information and Communication Technologies in organisations and households. The strategy thus combines principles of Universitas Scientia, Universitas Internatia and Universitas Virtualis. Future behaviour and competitive environment can be described in three scenarios: "A prosperous and just Europe", "A turbulent world", "Recession and reorientation". The strategist can choose among eight weighted alternatives. An overview of expected changes and factors is described in detail. These changes will influence the near future life of both the academic staff and the students, and will influence the ways the university must formulate for its long-term strategy of development.
Key-words: strategic decision; strategic management; higher education; decision space; decision alternatives; scenarios.

Působení nízkých teplot na fotosyntézu a růst u vybraných odrůd rajčat (Lycopersicon esculentum Mill.).
Authors: H. Hniličková, J. Duffek, F. Hnilička
Page: 101-105
English / Anglicky:
Pot trials were conducted to study the effect of low temperatures as affected the photosynthesis, stomatal conductivity, stomatal resistance and growth of potato (Lycopersicon esculentum Mill.) varieties - Start S F1, Monika F1 and Stupické polní rané. Plants of the control variant were placed in the glasshouse (20/16 °C day/night) and plants under stress were kept four days in outdoor unfavourable weather conditions (minimum air temperature was measured during the trial - 1 °C). Relatively short-term effect of low temperatures induced significant changes in conductance and resistance of stomata in all studied tomato varieties and rate of photosynthesis much decreased. After the return into optimum conditions stomatal conductance gradually recovered and the resistance of stomata reduced together with gradual increase of rate of photosynthesis. During four days of recovery the rate of photosynthesis returned in studied varieties on average to the level 8O % of the rate of photosynthesis of the control plants. Low temperatures reduced the dynamics of the growth of plants under stress in such a way that even four weeks after decline of unfavourable temperature conditions these plants showed the 10.5-day growth retard compared with the control (Start S F1 and Monika F1) and 15.6-day retard in the variety Stupické polní rané.
Key-words: low temperature; Lycopersicon esculentum Mill.; rate of photosynthesis; stomatal conductance to water vapour; stomatal resistence, growth.
