Abstract

Phenolic compounds and glucosinolates have been improved as natural bioherbicides for controlling weeds. So, two pot experiments were conducted. Both experiments aimed to study the allelopathic potentiality of Eruca sativa (ESSP) and Sinapis alba seed powder (SASP) on Lupinus albus and associated weeds Phalaris minor and Malva parviflora. Treatments were applied as follow: Six treatments were applied by sole incorporation of ESSP (10, 20, 30 and 40g/pot) and (SASP) at (5 and 10 g/pot). Other four treatments were applied by mix incorporation of ESSP at the aforementioned successive concentrations with SASP at (5 g/pot). Moreover, four treatments were applied by mix incorporation of ESSP at the aforementioned successive concentrations with SASP at (10 g/pot). Additionally, two control treatments of healthy and infected plants were applied for comparison. Although the recorded results improve that all allelopathic treatments minimized dry weight of the two investigated weeds, but mix incorporation is more effective than sole incorporation. Concerning to Lupinus albus mix incorporation treatments also scored the highest growth and yield parameters after the healthy control treatment. However, the chemical analysis of both investigated allelopathic plant materials ensured the presence of glucosinolates and phenolic compounds which have a bioherbicidal inhibitory effect on weeds.
