Sažetak

The paper presents the results of the achieved corn grain yield under different sowing systems in 2016. at the Slovinska Kovačica experimental field (45°45ʹ44.85ʺ N; 17°0ʹ21.43ʺ E). Sowing was done in double rows with a spacing of 22 cm (twin row technology) and in the standard way with a row spacing of 70 cm. Two maize hybrids, P0023 (FAO 420) and P0412 (FAO 520) sown in four different set of plants, were used. Analysis of variance showed that the sowing system and set of plants had a statistically significant effect on the achieved grain yield (kg ha-1). In standard sowing, the hybrid P0023 in an average of 64 116 plants ha-1 achieved a grain yield of 13 374 kg ha-1, and in the sowing in twin rows, the grain yield was increased by 5,12 %. The highest yield of the same hybrid in standard sowing was achieved with 94 466 ha-1 plants (14 264 kg ha-1), while in twin row the yield was 15 004 kg ha-1 or 5,19 % higher. Increasing the average set to 103 741 and 104 931 ha-1 plants in both sowing systems led to a decrease in grain yield to 13 237 and 14 143 kg ha-1, while sowing in double rows and in these conditions resulted in an increase in yield of 6,84 %. Hybrid P0412 with 95 935 plants ha-1 in twin row achieved a grain yield of 14 994 kg ha-1 or 5,82 % more, while with 105 143 ha-1 plants in twin rows higher yield was also recorded by 4,56 %. The best result in the experiment with hybrid P0023 was achieved by sowing in twin rows with 95 389 plants ha-1 and hybrid P0412 also by sowing in twin rows with 76 133 ha-1 plants. In the twin row sowing system, slightly lower grain moisture was found at harvest time in both hybrids.
