ABSTRACT Orobanche foetida is a devastating weed parasitising faba bean crops in Tunisia. Several methods have been used for controlling this parasite, but without much success. In this study, the effect of intercropping with fenugreek on O. foetida infestation and faba bean production was studied. Results showed a significant reduction in O. foetida infestation in the susceptible (Badi) and resistant (Najeh) faba bean cultivars when intercropped with fenugreek in field, pot and petri dish experiments. This reduction appeared to be related to reduced seed germination and low numbers of underground Orobanche attachments, which may have been as a result of allelochemicals released by fenugreek roots, though this was not confirmed in this study. Intercropping with fenugreek also resulted in a significant increase in the shoot dry weight and seed yield especially in the resistant cultivar Najeh. These results attest that intercropping with fenugreek can be used in an integrated strategy management to reduce broomrape infestation.

与胡芦巴（Trigonella foenum-graecum）间作提高了蚕豆（Vicia faba）的种子产量并减少了Orobanche foetida侵染

摘要 Orobanche foetida 是一种毁灭性的杂草，寄生在突尼斯的蚕豆作物上。已经使用了几种方法来控制这种寄生虫，但没有取得多大成功。在这项研究中，研究了胡芦巴间作对 O. foetida 侵染和蚕豆生产的影响。结果表明，在田间、盆栽和培养皿实验中与胡芦巴间作时，易感（Badi）和抗性（Najeh）蚕豆品种中的 O. foetida 感染显着减少。这种减少似乎与种子发芽减少和地下 Orobanche 附着物数量少有关，这可能是胡芦巴根释放的化感物质的结果，尽管本研究未证实这一点。与胡芦巴间作也显着增加了芽干重和种子产量，特别是在抗性品种 Najeh 中。这些结果证明，与胡芦巴间作可用于综合战略管理，以减少扫帚菜的侵染。
