Strniskové meziplodiny ve struktuře rostlinné výroby

This thesis deals with the production capabilities of stubble catch crops and their effect on yield of subsequent of spring barley. The field experiment was conducted on clayey-loamy fluvizem in the maize-growing region from 2006 to 2013. Experiments involved altogether ten different catch crops. Vegetation intercropping was established after the harvest of winter wheat in two periods (immediately after harvest crop and in mid-September). Spring barely was sown after these catch crops. Nitrogen fertilization was omitted to highlight the effect of catch crops on all variants in 2010. Analysis of the amount of fresh matter and dry matter stubble catch crops was conducted in the years 2006 - 2013 and the vegetation index NDVI was evaluated in the final year of monitoring. Another part belonged to classify the yield of spring barley grown after catch crops. A negative relationship between the yield of catch crop and that of spring barley was observed in the variant without nitrogen fertilization. Growing of catch crops on yield of spring barley had a positive impact in case of application of nitrogen.

The relationship between Normalized Difference Vegetation Index (NDVI) and selected agrometeorological parameters (yields of selected crops, water balance) was investigated. The source for NDVI was Spectroradiometer MODIS within satellite Terra and it was available for grids in resolution 500 x 500 m from 2000 to 2010. The analysis was conducted within 12 grids spread through Southern and Central Moravian region. The information about cultivated crops (including spring barley, winter wheat, maize for grains, sugar beet and winter rape) were collected from the farmers and water balance simulated using SoilClim model.
Assimilation of remote sensing methods and data by land adjustment
PINKAVOVÁ, Šárka
This diploma thesis covers questions of remote sensing in relation to land adjustment. On water area is showm usage of the vegetation index NDVI and the Tasseled Cap transformation. Satellite images were processed in computer software ERDAS IMAGINE.
