Abstract
Test trials were carried out in the years 1988–2000 in order to determine the effects of N-fertilization on yield, its composition as well as protein and nitrogen content of grain of new cultivars of both naked and hulled oats. Positive growth responses to doses of nitrogen fertilization were observed. At the highest dose of nitrogen fertilization, of 90 kg·ha-1, the Sławko and Akt cultivars yielded 5.02 kg·ha-1 and 3.84 kg·ha-1 grain, respectively. The number of spikelets and weight of grains per panicle were mostly affected by the increasing nitrogen fertilization. The weight and number of 1000 grains, however, didn’t change with the fertilization increase.
