The study was conducted at the Lipki Agricultural Experiment Station in Lipnik near
Stargard Szczeciński on acid brown soil formed of light glacial sand on clay (5 Bw pgl : pgm),
which is characterised by low content of humus on Ap level (1.57–1.59%) and clay particles
(11.9–12.4%). The field experiment was set up in split-plot system in four replications, with an
area of a single plot of 12 m2. The study included two factors: I – doses of phosphorus and
potassium (P + K kg . ha–1): 60 + 120 and 90 + 180, II – doses of nitrogen (N kg . ha–1): 0, 40, 80
and 120. The experiment was established in 2010 by sowing Dactylis glomerata seeds of
‘Tukan’ variety (8 kg . ha–1) in spring barley harvested for grain. The study included two years of
seed collection (2011 and 2012). The study determined plant density in the years of full use,
number of generative shoots per plant, inflorescence length, number of spikelets and seeds per
inflorescence as well as seed and straw yield. Biometric observations were conducted in
25 randomly selected inflorescences from each plot. Seed and straw yield was determined
on the area of each plot during seed harvest. Dactylis glomerata of ‘Tukan’ variety was
characterised by higher level of yields in the first than in the second year of seed collection. The
obtained results indicate, that when establishing a plantation on light soil with companion
planting in spring barley, it is advisable to use 120 kg N, 60 kg P and 120 kg K . ha–1. The
increased phosphorus-potassium fertilisation (90 kg P and 180 kg . ha–1) did not change the
studied morphological features of plants (number of generative shoots per plant, length of
inflorescence, number of spikelets and seeds per inflorescence), while fertilising with nitrogen in
doses of 40, 80 and 120 kg . ha–1 had a positive effect on increasing the above mentioned
features.
