The study presents dependence of winter triticale yielding on the sum and distribution of rainfalls in the growth stages: beginning of vegetation - shooting, shooting - dough maturity and in the whole vegetation season. Winter triticale was grown on wheat and rye soils in the middle part of Poland. Based on 2437 one-year experiments from 19 experimental stations over 1981-1996, a model of yielding has been elaborated. The study allowed determining which of the studied parameters and when exerts an essential impact on the yield of winter triticale. The largest yields of ca. 7.3 t/ha was obtained on wheat complexes when rainfall was 200-240 mm. The number of days with precipitation less or equal 5 mm and the total number of days with rainfall did not significantly correlate with the yield. The largest yield (6.5 t/ha) on rye complexes was obtained at total rainfall ca. 200-260 mm, the number of days with rainfall less or equal 5 mm over 45 days and overall number of days with rainfall greater than 60 days
