dcterms:description
Článek se zabývá vztahem mezi zemědělským suchem a výnosy jarního ječmene v České republice. The relationship between detrended district yields of spring barley (1961–2000) and meteorological drought was assessed by Palmer Z-index. We found that the seasonal water balance (April–June) significantly (P = 0.05) influences the spring barley production in 51 out of 62 evaluated districts. Coefficients of correlation varied in individual districts from 0.19 to 0.70, with the highest values being found in southern Moravia. Data analysis revealed the presence of six distinct groups of districts with a specific drought-yield relationship. The most drought-sensitive cluster included five districts in the South East of the country. On the other hand, the districts in Northern Moravia and Silesia belong among the least sensitive to agricultural drought. The study also defined threshold values of seasonal drought (sums of relative Palmer Z-index lower than –8 and –10, respectively), below which medium to severe spring barley yield reductions are very likely, regardless of the district of occurrence.
