EFFECT OF THE SOWING METHOD, DATE AND ROW SPACING ON THE YIELDING OF ┤STADION┤ PERENNIAL RYEGRASS (LOLIUM PERENNE L.) CULTIVATED FOR SEED

ABSTRACT


The aim of the present research was to evaluate the yielding of perennial ryegrass (Lolium perenne L.), 'Stadion' lawn cultivar grown for seed, depending on the sowing method, date and row spacing. The research was carried out at the Experiment Station for Cultivar Testing at Chrz╣stowo, in the vicinity of Bydgoszcz. The experiment was carried out over 1998-2002 in three series; each of them included the sowing year and two years of full use for farming purposes. The experimental factors included: I - sowing method/date: autumn pure stand, spring pure stand, undersown perennial ryegrass in spring barley cultivated for green matter and undersown perennial ryegrass in spring barley grown for grain, II - row spacing: 12 cm - narrow, 24 cm - average wide, 36 cm - wide and 48 cm - very wide. In the first year of full use for farming purposes, the seed yields were lowest when ryegrass was sown in autumn. Furthermore the yield of perennial ryegrass sown in spring in pure stand was s
