The longest spikes were obtained in the variant with all three nutrients used in highest amount. Number of fertile spikelets were low in treatments without nitrogen applied, and absolutely lowest on variant only with P2. The largest number of fertile spikelets obtained on the triple fertilization variants with increased nitrogen rate. The smallest weight of grains per spike was obtained in a single fertilization with P and K, as well as the control treatment, and was the highest in the variants with most intensive fertilization with all nutrients. Also, the weight of 1000 grains was highest in balanced fertilization with all nutrients (N2P2K2), but similar values were obtained in all treatments where nitrogen was applied. Spike index and harvest index did not show special regularity at different levels of fertilization, but the values of both parameters were higher in treatments fertilized with all nutrients. The highest yield was achieved in the variant N3P2K2 (6.10 t/ha), although the high yield of more than 5 t/ha was obtained and the other triple treatments where nitrogen is applied in the maximum amount, as well as variants with moderate doses of all nutrients.
