dc.description11Abstract. Maize, one of the most important cereals species grown in Poland, use large quantities of nitrogen, but water defi-cit through the vegetation period might lead to yield reduction and diminish nitrogen uptake. The aim of the study was to char-acterize the productivity of the crop, depending on its nitrogen and water use efficiency. In two locations, in Western and Eastern Poland, eleven-year field experiments with maize grown for grain were conducted. Maize was fertilized with increasing rates of ni-trogen: 50, 100, 150, 200 i 250 kg N ha-1. It was found, that grain yields of maize raised statistically significant up to 8.03 tha-1 under 150 kg Nha-1. Such a dose guaranteed: nitrogen uptake 182 kg Nha-1, nitrogen use efficiency 121%, nitrogen surplus -32 kg Nha-1, water use efficiency 14.5 kgha-1 mm-1, and nitro-gen utilization efficiency 43 kgkg-1. Increasing nitrogen doses over the years was not justified because maize productivity was limited by water availability under higher nitrogen rates.en-US
