Italian ryegrass cv. Tetraflorum sown at different inter-row spacings and seeding rates was examined under agroecological conditions of Macva (Serbia). The study tested a hypothesis that Galium aparine growing in Italian ryegrass seed fields reduced the growth of established species and consequently decreases seed yield. Four established methods were tested: narrow and broad row spacings (20 and 60 cm) in combination with low and high seeding rates (5 and 20 kg/ha). Control treatments were sprayed with the herbicide Starane-250 (1 l/ha) to eradicate Galium aparine. Italian ryegrass was affected by G. aparine in three of the four cultivation methods. In this experiment, seed yield reached 973 kg/ha in control treatments and 956 kg/ha in the presence of Galium aparine. Italian ryegrass straw yield was in linear correlation with seed yield.
