The aim of the study was to determine intensity and frequency of occurrence of
atmospheric drought during the development periods of spring triticale in north western Poland.
In order to realize the task, the results of agrophenological observations of spring triticale
pattern were used. The observations were carried out at 8 COBORU (Research Center for
Cultivar Testing) experimental stations located in north western Poland over 1984–2004. The
experimental material consisted also of the precipitation totals gathered at 12 IMGW (Institute of
Meteorology and Water Management) stations during the years 1965–2004. The drought
periods were identified on the basis of the standardized precipitation index SPI. It was stated
that the largest number of dry periods in north western Poland were observed in the central part
of Pomeranian Lakeland and in the Szczecin Lowland and the smallest – in the central part of
the Coast. Spring triticale was threatened most by the occurrence of drought during the periods
of emergence-tillering and heading-wax maturity. Very strong and extremely strong droughts
occurred more frequently in the period of heading-wax maturity and sowing-emergence, least
rarely – in the period of shooting-heading. According to the SPI index, periods of extreme
intensity of drought occurred most frequently in the south western part of the investigated area,
whereas they were not a threat in its eastern part and in the vicinity of Szczecin. There was no
statistically confirmed increase in frequency of occurrence of atmospheric drought in north
western Poland over the years of studies.
