ABSTRACT

Field trials were conducted 2010–2012 in soybeans (Glycine max (L.) Merr.) to investigate cultivar choice, suitable seeding dates and row distances for cropping in Sweden. The cultivar trials showed that commercially available varieties of the 000-group can be used for cropping in Sweden. Yield typically amounted to 1500–2500 kg ha⁻¹ of dry marketable seeds. Cultivars introduced to Sweden should be tested in the field before large-scale production as the 000-classification not fully is valid for Swedish conditions. Row distance (12.5; 25 and 50 cm) had no overall statistically significant impact on yield, but 25 or 50 cm are recommended as these distances are suitable for physical weed control such as row cultivation or torsion weeding. Seeding in the period May 15–30th is recommended to secure germination and yield. The outcome of the trials was supported by results from field demonstrations and commercial cultivar trials in 2013–2014.

摘要

2010-2012 年在大豆 (Glycine max (L.) Merr.) 中进行了田间试验，以研究瑞典的栽培品种选择、合适的播种日期和行距。栽培品种试验表明，000 组的市售品种可用于在瑞典种植。产量通常为 1500–2500 kg ha ^-1干燥适销对路的种子。引入瑞典的品种在大规模生产前应进行田间试验，因为 000 分类不完全适用于瑞典条件。行距（12.5；25 和 50 厘米）对产量的总体统计上没有显着影响，但建议使用 25 或 50 厘米，因为这些距离适用于物理杂草控制，例如行栽培或扭力除草。建议在 5 月 15 日至 30 日期间播种，以确保发芽和产量。试验结果得到了 2013-2014 年田间示范和商业品种试验结果的支持。
