The trials were carried out in the regular production of the seed maize ZP 680 at the agricultural estate "Nova Budućnost" Žarkovac during 2001 and 2002. Sowing densities (71,400, 85,500, 99,900 plants ha"1) affected varying of yields (4.01, 4.38. 4.40 t ha"1). The 1000-seed weight decreased over increased densities (305.6, 2912, 282.5 g). Germination was even over densities (95.0, 94.9, 94.7 %). A greater number of germinated seeds per area unit (13,122,000, 15,022,000, 15,569,000) was obtained in greater densities. The percentile share of fractions in the weight was uniform over all sowing densities
