Název v původním jazyce

Relationship between Agricultural Drought and Yields of Selected Crops at Regional Scale within the Czech Republic

Popis výsledku v původním jazyce

The main objective of submitted study was to assess whether an occurrence of a seasonal agricultural drought has any quantifiable influence over the production of selected crops which included spring barley, winter wheat, maize, potato, winter rape, oats, rye and hay from permanent meadows. Analysis was carried out in 77 districts of the Czech Republic (mean district area 1000 km2) for the period from 1961 to 2000. In each crop specific analysis only districts with sowing area higher than 0.5% of totalnational acreage within at least 2/3 of evaluated years were considered. Based on the previous research and results of other authors we selected the Palmer's Z-index as the most appropriate indicator of agricultural drought. The Z-index is derived usinga soil moisture/water balance algorithm that requires a time series of monthly air temperature and precipitation data and information on the maximum soil water holding capacity (MSWHC) in the rooting zone. The Z-index is a measure of the
