This study was designed to evaluate the synergistic effect of 6 different weeds (Chenopodium album, Avena sativa, Lathyrus sativus, Cirsium arvense, Rumex dentatus, and Phalarus minor) on the growth and related attributes of three cultivars (Faisalabad1, Sahar6 and Galaxy) of wheat (Triticum aestivum L.). Current study aims to exploit the allopathic potential of weeds on germination efficiency, growth dynamics and biomass accumulation. Aqueous extracts of weeds roots and shoots were prepared in different concentrations. Experiment was carried out in sterilized petri dishes and also in field (control environment). Roots and shoots extracts exhibited unalike effects on the same cultivar at same concentration. Roots extract (5%) promoted the radical length of 2 weeks old seedling (Sahar6 cultivar) 1.5 times (8.64 cm) as compared to the control. Plumule lengths of sahar6 and galaxy cultivars were positively effected by 5% of both extracts. Fresh weight of Sahar6 cultivar has been increased 1.4 folds (0.82 g) while dry weight has been increased 7 folds (0.78 g) as compared to control by treating with 5% of roots extract. Weed extracts supported the plant height and leaves number in first 2 weeks while a decline have been observed in both height and leaves number from week 3 onward. Based on current study, it can be suggested that phytochemicals in weed extracts contains the allelopathic potential and can promote the growth parameters of wheat crop when used in optimum concentration.
