Résumé
The present study was carried out at the Weed Science Research Laboratory, The University of
Agriculture, Peshawar Pakistan (June-July 2013 and Sep-Oct 2013). To evaluate the most effective and
economical treatment for weed management in maize (Zea mays L.), the pot experiment was performed
using completely randomized design (CRD) with three replications. Allelopathic effects of Sorghum
bicolor (L.) Conard Moench., Helianthus annuus L., Parthenium hysterophorus L, and the commercial
herbicide (atrazine @ 18 g L-1) was used for comparison. The data were recorded on germination and
seedling growth of test species (Zea mays, Trianthema portulacastrum and Lolium rigidum). The data
showed that S. bicolor + H. annuus + P. hysterophorus water extract (WE) @ 33.33 + 33.33 + 33.33 (g
L-1) reduced dry biomass of T. portulacastrum and L. rigidum by 35 and 41% respectively, whereas the
commercial herbicide by 45-47%. Maize seeds were found more tolerant than the weed species tested.
Hence, it is concluded that extracts applied in mutual combination had more inhibitory effect than their
sole applications, however, the efficacy of atrazine was more effective in suppressing germination and
seedling growth of the tested species. The degree of toxicity for the various treatments can be placed in
the following array of inhibition: Herbicide > combined extracts > isolated extracts. The current study
showed that all the tested allelopathic plants contain water soluble allelochemicals which could
inhibit/retard the germination percentage and seedling growth of the tested species. Hence, the findings of
the current study suggest that it is possible to use these extracts as an alternative to synthetic herbicide (s)
for sustainable weed management in maize. However, further studies are suggested to confirm our
findings under field conditions.
