Abstract
The field experiment was carried out in the Experiment Station Złotniki near Poznań. The influence of sprinkler irrigation (non irrigated, irrigated), cultivar (Jawor, Skrzat, Sławko) and nitrogen fertilization (0, 50, 100, 150 kg N/ha) on the oats yield, yield components and nitrogen productivity was investigated. Grain yield was influenced by interaction of irrigation and nitrogen fertilization as well as irrigation and cultivar. Irrigation increased panicle number and 1000 grain weight, N-fertilization increased panicle number and grain number in panicle for all cultivars. Nitrogen productivity was dependent on irrigation, cultivar and N-rate.
