| Abstract | ||
| These experiments were carried out during the summer seasons of 2003 and 2004 at the greenhouse of the National Research Centre. The experiments aimed to study the effect of adding different concentrations (0 %, 5 %, 10 %, 15 %, 20 % and 25 % w/v) of aqueous extract of lupine (Lupinus termis cv. Giza 1) on the growth, yield, yield components and some chemical composition of mungbean as well as their effect on the growth of jew's mallow and purslane. The lupine seed extract were added weekly for 12 weeks after 30 days of seedling establishment of plants The data revealed that the fresh and dry weight of jew's mallow was stimulated by Lupine seed extract at 5 % concentration, while no appreciable changed occurred with 15%, whereas the higher concentration (20 % and 25 %) showed inhibitory effect. However, all Lupine seed concentrations caused stimulation in the fresh and dry weight of purslane. The data also illustrated that mungbean growth and seed yield as well as total protein were stimulated by lupine seed extract at 5 % concentration. No appreciable changes occurred with 15 %, whereas the higher concentrations (20 % and 25 %) showed an inhibitory effect. Lupine seed extract at 5 % concentration has a positive allelopathic effect due to its ability to increase plant growth and to stimulate mungbean yield production. These results suggest the possibility of the potential beneficial involvement of Lupine seed extract as crop-crop stimulator, through its application at lower concentrations after mungbean emergence. This treatment could be effective in enhancing crop production. | ||
