Soybean (Glycine max (L.) Merrill) is the world's leading oleiferous plant and protein legume. In Slovenia, up to 3000 hectares of fields have been sown with soybean in recent years. Since we do not have domestic soybean varieties, we grow promising foreign varieties that need to be tested under our growing conditions. At the laboratory field of the Biotechnical Faculty in Ljubljana, we conducted experiments with 8 foreign promising varieties in 2015 and 2016 ('Aligator', 'Ema', 'ES Dominator', 'ES Mentor', 'Korona', 'Lucija', 'Naya' and 'Silvija PZO'). In both experimental years we sowed soybeans on 19 May; in the first year the crop emerged on 28 May, and on 27 May in the second year. The harvesting took place mechanically, on 30 September in the first year and on 6 October in the second year. The crop emergence was studied, and the final yield at 9% grain moisture and the absolute weight of the grain produced. All varieties exceeded the optimal yield of 60 plants/m2; the average emergence in 2015 was 76 plants/m2. The average emergence in 2016 was the same as the optimal one, although three varieties had an emergence 63% smaller on average than the optimal one. The average harvest in 2015 was 45.3% higher than the Slovenian average (2700 kg/ha), while the average harvest in 2016 was 30.5% lower than the Slovenian average (3000 kg/ha). The average harvest of both years was 2850 kg/ha. The highest average harvest in both experimental years was provided by the 'ES Mentor' variety (4118 kg/ha), which also had the highest absolute mass on average (203.5 g). In both years, the 'ES Dominator' variety stands out with a low absolute mass (158.6 g).
