The paper presents the seed production technologies of maize sown on three different sowing dates. Seeds of three maize inbred lines (L1, L2, L3) were used as a seed material in the location of Zemun Polje in 2018. The objectives of the present study was to determine the importance of different sowing dates as a method to overcome stressful conditions caused by unfavourable environmental factors, as well as to point out to a significance of the seed size in sowing. Effects of the following factors were observed in relation to emergence and the maize grain yield: sowing date (SD), seed fraction (LF, SF and PF) and genotype (L). The gained results indicate that the lowest percentage of emergence was determined in the variant L2/SD2/SF (34%), while the highest grain yield was determined in the variant L3/SD1/ PF 8.86 t/ha. The standard deviation of the yield is the largest for variants with the highest yield.
