- Abstract
Present study was conducted in laboratory conditions at Department of Weed Science, University of Agriculture, Peshawar, Pakistan during 2013 to evaluate wheat biotypes against the allelopathy of three problematic weeds. Wheat biotypes were collected from six districts viz, Peshawar, Kohat, Mardan, Mansehra, Swat and Chitral and were evaluated against the allelopathy of three problematic weeds of wheat crop including Ammi visnaga, arvensis and Galium aparine. A control treatment was also settled for the Convolvulus comparison in laboratory conditions. The results revealed that the wheat seeds collected from the area having cooler climatic conditions of Chitral, Swat and Mansehra were more sensitive to the toxicity of weeds giving a germination percentage in the range of 30-45 percent as compared to those of the hot climatic areas like Peshawar, Kohat and Mardan which exhibited 50-59 percent germination. In case of weeds toxicity the extract of Convolvulus arvensis caused more suppression in all wheat biotypes and restricted the seed germination to 8.33 percent compared to other weed species. The study suggested that the C. arvensis extract should be used against the weeds of wheat.
