The paper presents dependence of winter triticale yielding on the sum and distribution of rainfall in particular growth stages and throughout the vegetation season in the southern part of Poland on wheat and rye soils. The study was based on 1413 results of experiments carried out at 12 experimental stations in the years 1981-1996. Soil quality had a significant effect on winter triticale yielding. The highest yields of ca. 7.0 t/ha on wheat complexes were obtained under the following conditions: rainfall 180-220 mm, the number of days with rainfall less or equal 5 mm - 35-45 days and the overall number of days with rainfall 50-60 days. The respective figures for rye complexes (yield 6.5 t/ha) were: 220-260 mm, over 50 days and over 60 days
