Trend výnosů ječmene setého v kontextu vývoje klimatu
 Procházková, Andrea
With an agro-meteorological model AVISO (Agro-meteorological Computing and Information System) was computed water reserve in the soil which is utilizable by roots of the plants, for 16 trial stations ÚKZÚZ (Central Institute for Supervising and Testing in Agriculture) in the vegetation period 1975 -- 2010. Yield series of ÚKZÚZ stations, for spring barley (Hordeum vulgare L.), were correlated with values of water reserve which were expressed in % of available water holding capacity (% AWHC). Statistically conclusive relation between barley yield and % AWHC of the soil was determined in some stations, but not in an average in production areas. When the monitored period was divided into two stages (1975 -- 1990 and 1995 -- 2010) the decrease of % AWHC was confirmed in all production areas in the second period, except mountain area of production. For area Olomouc was carried out a long term air temperature analysis and precipitation amount in the period 1961 -- 1990 and for scenario periods 2021 -- 2050 and 2071 -- 2100. An evaluation of temperature rate is based on size of a standard deviation from normal and in precipitation rate on division of data file into percentiles. From comparison of periods is evident increase of months with above normal temperatures and of precipitation extreme months -- both under and above normal.
