Abstract

The paper presents the results of maize grain yield with different sowing systems in 2021 at the Tenja trial site of the Faculty of Agrobiotechnical Sciences Osijek. Five hybrids were sown in double rows (twin row) at a distance of 22 cm, and in the standard way with a row distance of 70 cm. In standard sowing, hybrid H2 achieved the highest average grain yield kg ha-1 (13 610), while in twin row sowing, a yield of 14 927 kg ha-1 or +1317 kg more (9,67 %) was recorded. The lowest grain yield in standard sowing was recorded at hybrid H1 of 11,088 kg ha-1. The same hybrid, when sown in twin rows, achieved a grain yield of 12 496 kg ha-1, which represents an increase of +12,70 % or +1410 kg ha-1. With hybrid H3 in twin rows, a yield of 12 748 kg ha-1 was recorded, which is an increase compared to standard sowing of +1676 kg ha-1 or 15,14 %. Hybrid H4 in standard sowing achieved a grain yield of 12,088 kg ha-1, which is less compared to sowing in twin rows of -1499 kg ha-1 or 12,40 %. The average yield increase in twin row sowing for all 5 hybrids is 12,51 % (1504 kg ha-1). Analysis of variance revealed that there is a high significance between the factors "hybrids" and "sowing method" on grain yield as well as grain weight per cob. The mentioned factors did not have a statistically significant effect on the realization of the set of plants in sowing. Differences in grain moisture were also statistically significant only with the factor "hybrids"
