Hodnocení stavu porostů obilnin s využitím spektrálních měření

Master thesis is focused on the evaluation of cereal crop stands with the use of spec-tral measurements and its implementation by crop management practices. In the literature review the basics of yield formation and crop survey are described as well as the im-portance of crop monitoring by spectral measurement for decision support in precision farming practices. Practical part of the thesis includes statistical evaluation of field expe-riment in 2017 and 2018, which were focused on the mapping of crop heterogeneity within the fields with winter wheat. In this experiment, plant samples were taken and ana-lyzed for estimation of nitrogen content and amount of above-ground biomass in various part of the field. This sampling was extended by proximal measurement of solar radiation using spectroradiometer in visible and near infrared part of electromagnetic spectrum. Da-ta processing was performed using descriptive statistics and correlation and regression analysis.The results showed high spatial variability of observed fields.Correlation and re-gression analysis evaluated the relationship between spectral measurement of the stand, represented by vegetation indices, and its laboratory estimation. As the conclusion, spectral measurements was be recommended as a complement to traditional methods of agrobiological control of cereals and could be used for delineation of management zones in site specific crop management.
