ABSTRACT To study the effects of intercropping different sugar beet cultivars with soybean, Moldavian balm and proso millet in an organic production system on the yield and quality of sugar beet, a factorial experiment was conducted in 2016 and 2017 in West Azarbayjan, Iran. In 2016, the sugar beet-soybean intercropping resulted in the highest Na and α-amino-N concentrations in the sugar beet (2.384 and 2.879 meq. 100 g−1 beet respectively), but in 2017 the concentrations of these compounds were not significantly different between the intercropping patterns. For all intercropping patterns the land equivalent ratio (LER) was greater than one. In 2016, the highest LERT, based on white sugar yield, was obtained in the sugar beet–soybean intercropping system (1.27 for cv. Vaclav), but in 2017 the highest LERT based on white sugar yield, was obtained in sugar beet–Moldavian balm intercropping (1.24 for cv. Vaclav). Among the sugar beet cultivars, Ghazira had the highest sugar concentration and white sugar yield. It was concluded that the sugar beet–Moldavian balm intercropping system could be used in organic production systems to achieve high land productivity.

间作甜菜 (Beta vulgaris L.) 与小米、大豆和摩尔多瓦香脂对有机生产系统产量和品质的影响

摘要 为了研究不同甜菜品种与大豆、摩尔多瓦香脂和小米在有机生产系统中对甜菜产量和品质的影响，于 2016 年和 2017 年在伊朗西阿扎尔巴扬进行了一项析因试验。2016 年，甜菜-大豆间作导致甜菜中的 Na 和 α-氨基-N 浓度最高（分别为 2.384 和 2.879 毫克当量。100 g-1 甜菜），但 2017 年这些化合物的浓度并不显着间作模式之间的差异。对于所有间作模式，土地当量比 (LER) 均大于 1。2016 年，基于白糖产量的最高 LERT 是在甜菜 - 大豆间作系统中获得的（cv. Vaclav 为 1.27），但在 2017 年，基于白糖产量的最高 LERT，是在甜菜-摩尔达维亚香脂间作中获得的（cv. Vaclav 为 1.24）。在甜菜品种中，Ghazira 的糖浓度和白糖产量最高。得出的结论是，甜菜-摩尔达维亚香脂间作系统可用于有机生产系统，以实现高土地生产力。
