| Abstract: This study was conducted to evaluate the effect of leaf and seed water extracts of Moringa oleifera at different concentrations (0, 1.25, 2.5 and 5%) on the growth and flowering of Narcissus tazetta L as well as the growth of associated weeds. This study was achieved under greenhouse conditions at the National Research Center, Egypt, in the two winter seasons of the years 2014/2015 and 2015/2016. Leaf and seeds water extract of Moringa oleifera reduced the growth of both Beta vulgaris (broad weed) and Phalaris minor (grassy weed) as compared to the control. On the other hand, fresh and dry weights of leaves of Narcissus tazetta L., bulbs as well as flowering increased significantly by leaf and seed water extract over untreated control.... |

| Two pot experiments were carried out during two successive winter seasons of (2016 / 2017) and (2017 / 2018) at the green house of National Research Centre (NRC), Giza, Egypt. The experiments were conducted to compare the allelopathic effect of Beta vulgaris (shoot and root aqueous extracts at 3, 6, 9%) to chemical herbicides (clodinafop-Propargyl and Basagran at recommended dose (140 g/fed and 1.5 l/fed, respectively) in controlling weeds (Phalaris minor and Malva parviflora) associated with Lupinus albus plants. Results showed that all applied aqueous extracts caused reduction in two weeds biomass under investigation. Meanwhile, root aqueous extract was more effective than shoot aqueous extract in controlling weeds. It is worthy to mention that phenolic... |
