Abstract:

Allelopathic effects of different weeds’ aqueous extracts on germination and seedling growth inhibition of Maize were studied. Treatments comprised of control (distilled water), Ammi visnaga (L.) Lam. Convolvulus arvensis L., Galium aparine L. and Trianthema portulacastrum L. shoot aqueous extracts were applied and were replicated four times using a completely randomized design with factorial arrangement. The results showed a significant inhibitory effects (pGalium aparine L. while the smallest number was recorded in the Petri dishes treated with Trianthema portulacastrum L. Fresh weight of root is greatly affected by both the aqueous shoot extract of Convolvulus arvensis L. and Trianthema portulacastrum L. (0.065 and 0.112, respectively) and maximum fresh weight of root was recorded for the shoot aqueous extract of Ammi visnaga (L.) Lam. (0.300). The result recorded of fresh shoot weight for the aqueous shoot extract of Ammi visnaga (L.) Lam. is the smallest (0.197) as compared to control treatment (0.470). The dry shoot weight was affected by control treatment (0.0725) as compared to shoot aqueous extract of Galium aparine L. (0.767). And dry root weight was recorded lightest (0.052) for control and was noted the heaviest for the shoot aqueous extract of Galium aparine L. (0.302).
