Abstract

In this paper, the results of maize grain yield (kg ha-1) sown in standard and twin row technology are shown. The research has been conducted at the experimental field of Faculty of Agrobiotechnical Sciences, near location of Tenja (45°31’1.83” N 18°46’3.5” E) in the period 2016-2018. Maize hybrids H1 = FAO 290, H2 = FAO 380, H3 = FAO 410, H4 = FAO 450 and H5 = FAO 590 were sown using standard sowing (row spacing at 70 cm) and twin row sowing (22 cm spacing between double rows). In standard sowing, hybrid H1 had the highest grain yield of 11,450 kg ha-1, whereas in twin row sowing it had 12,243 kg ha-1, which was higher by 3.77-9.66% than the standard, depending on the cultivation year. Hybrid H2 in twin row sowing had grain yield 6.46-10.97% greater than standard sowing. Hybrid H3 in standard sowing had average grain yield of 11,731 kg ha-1, whereas in twin row sowing, it was 12,763 kg ha-1 (greater by 3.45-9.95%). The highest grain yield difference between sowing technologies has been observed at H4 hybrid, with 11.72% greater yield at twin row sowing. At hybrid H5, the smallest differences were observed between sowing technologies, so in 2018, twin row sowing produced a lower yield by 0.59% relative to standard sowing.
