Plant released phytotoxins (allelochemicals) have important influence on agro-ecosystem through their inhibitory effect at higher doses and stimulatory (hormesis) effects at low doses on crop and weeds. A study to investigate the reaction of wheat and associated weeds to foliar application of sorghum and moringa water extracts was conducted. Foliar application of whole plant sorghum aqueous extract (sorgaab @ 18 L ha^-1)and 3.33% moringa extract (14.9 L ha^-1) alone and in combination, water spray were foliar applied at 60 or both at 60 and 90 days after sowing (DAS). A control treatment without any foliar spray was used for comparison. Two sprays of sorgaab (18 L ha^-1) at 60 and 90DAS suppressed total weed density and dry weight by 56.7-58.4% and 59.4-61% respectively while, lambsquarters and canary grass density, fresh and dry weights by 57.8, 43.2, 73.3% and 53.1, 60.1, 77.5% respectively at 60 and 90 DAS. The highest grain yield (3.38 t ha^-1) with 35% increase as compared to control was observed where two foliar sprays of sorgaab at 18 L ha^-1 was applied at 60 and 90 days after sowing (DAS). Two sprays of sorgaab at 18 L ha^-1 alone and in combination with moringa water extract at 14.9 L ha^-1influenced the yield traits of wheat over control. Conclusion, sorghum and moringa extracts can help to control weeds in wheat that ultimately help to increase wheat yield.
