The development of thermophilic vegetables grown in the Czech Republic in relation to climate

This Master's thesis deals with the yield and quality parameters of thermophilic vegetables according to the risk occurrences of extreme weather events in the Czech Republic. This thesis is also focused on the impact of climate change and extreme weather events on development of vegetable crops, and possible cultivation of thermophilic vegetables outside of typical growing areas. The major part of vegetable production is affected by agro-climate, biological, technical and economic aspects. The main tasks of this study are follows: (i) to combine daily meteorological variables with annual yield datasets, (ii) to provide basic statistical analysis of yield of thermophilic vegetables and weather events, and (iii) to identify days with heat stress (both the spring frost and tropical days) during the growing cycle of thermophilic vegetables for the period from 2005 to 2015. This thesis also contains detailed research of phenological phases of tomatoes (Lycopersicon esculentum) during each farming year and impact of different weather extreme events on plant development and yield. Results based on the analysis of historical meteorological observations and descriptive statistics of yield parameters indicate that the positive factors are higher temperatures, optimal rainfall in combination with irrigation and higher intensity of global solar radiation. Conversely, frosts days during planting and increased intensity of rainfall in all phenological phases are detected as negative factors
