Výskyt poľnohospodárskeho sucha a jeho vplyv na vybrané poľné plodiny
 Leskovská, Natália
Agricultural drought in recent years severely caused losses on the yields of cultural crops. In this thesis was assessed the dependence between drought indicators and yields of two important crops in the Czech Republic (winter wheat and spring barley). As drought indicators were selected precipitations and actual evapotranspiration, observed in 2000 – 2017 from March to June, which are the most important for the production of biomass crops. Episodes of drought were studied across the gradient profile of the South Moravian Region, Olomouc Region and Vysočina Region. From the monitored period from 2000 – 2017, the years with the lowest yields were selected in the resulting regression analysis of the correlation relationship. The highest dependence of the precipitation and yield of winter wheat was from April to May in 2007, when the coefficient of determinant reached 0.82, which means that yield variability was affected from 82% by the indicator of precipitations.
