Abstract: Field experiments were carried out in 2005 and 2006 at two localities: Lipnik near Stargard Szczeciński and Kruszyn Krajeński near Bydgoszcz. The experiments were designed by split-plot method in 3 replications. Two factors were considered: irrigation (control, sprinkler irrigation) and nitrogen fertilization (0, 40, 80 and 120 kg N ha -1). Yields of non-irrigated true millet grown on the soil of the V quality class dependent on rainfall amount during the vegetation period. Lower yields (1.46 t ha-1) were noted in the year characterized by lower rainfall (161 mm from May 1 to August 31). Higher yields (2.45 t ha-1) were obtained in the year with higher rainfall (229 mm). Water needs of true millet during the vegetation period (May-August), estimated as optimal rainfall according to Klatt and Press, were higher on the very light soil (V quality class) at Kruszyn Krajeński (278mm and 294 mm, respectively) than those – on the light soil (IVb quality class) at Lipnik (260 and 256 mm, respectively). Highest rainfall deficiency during the vegetation period of true millet – estimated as a difference between optimal rainfall according to Klatt and Press for a particular month and the rainfall total in this month – was noted in July. Production results of irrigation dependent on the soil complex. Sprinkler irrigation significantly increased grain yields of true millet cv. ‘Jagna’ by 1.9 t ha-1 (97%) on the very light soil (Kruszyn Krajeński). Under conditions of the light soil (Lipnik) sprinkler irrigation increased the grain yield by 0.6 t ha-1 (17%). Under conditions of sprinkler irrigation, increased nitrogen fertilization doses (from 0 to 120 kg N ha -1) caused a significant grain yield increase of true millet to the amount 4.53 t ha-1 and 4.07 t ha-1, on the soil of the V quality class and that of IVb quality class, respectively.
