Wheat is the most important cereal crop in Pakistan and contributes 72% daily caloric intake with per capita wheat consumption of the region. Weeds pose serious problems in crop production as weed control is ignored due to lack of education and poor financial resources of the farmers. A field experiment was conducted to assess the allelopathic effect of mulberry and sorghum water extracts at different concentrations against noxious winter weeds like Phalaris minor and AvenafatuaL. in wheat crop at the Agronomic Research Farm, University of Agriculture, Faisalabad, Pakistan. The experiment was conducted in randomized complete block design (RCBD) having four replications. All foliar treatments were applied after 30 days of sowing. Weedy check plot was kept for comparison and considered as a control. Mulberry water extract @ 36 L ha -1 was effective regarding weed density of canary grass with 58% and 57% at 45 and 60 DAS respectively as compared to weedy check. Combine application of sorghum and mulberry extracts @ 18 L ha-1 of each was good to decrease weed growth and hence the fresh weight by 59-63% and dry weight too. Mulberry water extract @ 36 L ha -1 was appeared better with 55% and 54% to control weed density of wild oat. Combine application of sorghum and mulberry extracts @ 18 L ha-1 of each produced higher number of productive tillers (343.75) per square meter and biological yield (13%) as compared to weedy check plot by discouraging the weed density and growth.
