The present study was conducted to investigate the allelopathic effect of lamb’s quarter (chinopodium album) concentrations on seed germination and early growth of different wheat varieties at Seed Testing Laboratory, Department of Agronomy, Sindh Agriculture University Tandojam during 2016. The lamb’s quarter water extracts of weeds at 50 and 100% concentrations were applied to determine their effect of seed germination, shoot length (cm), shoot fresh weight (mg), root fresh weight (mg), shoot dry weight (mg), root dry weight (mg) of test under laboratory conditions. The water extract of lamb’s quarter caused harmful effect on all growth parameters of wheat as compared to control treatments. The maximum seed germination (81.6%), shoot length (19.3 cm), root length (13.7 cm), shoot fresh weight (0.9440 mg), root fresh weight (0.9307 mg), shoot dry weight (0.9307 mg), root dry weight (0.3364 mg) was observed in control treatment whereas, the plant was treated with 100% allelopathic concentration was observed minimum seed germination (44.2%), shoot length (11.8 cm), root length (8.8 cm), shoot fresh weight (0.6293 mg), root fresh weight (0.2373 mg), shoot dry weight (0.2373 mg), root dry weight (0.1132 mg).The mean for varieties showed significant response to allelopathic concentrations. The maximum seed germination (70.8%), shoot length (16.0 cm), root length (13.1 cm), shoot fresh weight (0.9178 mg), root fresh weight (1.3744 mg), shoot dry weight (1.3744 mg), root dry weight (0.5007 mg) was recorded in Mehran-89 and minimum seed germination (58.8%), shoot length (11.0 cm), root length (9.7 cm), shoot fresh weight (0.6333 mg), root fresh weight (0.1967 mg), shoot dry weight (0.1967 mg), root dry weight (0.1167 mg) was noted in wheat variety Moomal. In respect of the above finding it can be concluded that 100% lambs quarter water extract has more negative effects on the germination and related traits of all wheat varieties.
