A laboratory experiment was conducted to assess the allelopathic effect of aqueous extracts of sorghum and sunflower on germinating seedlings of Phalaris minor and wheat. 10% (w/v) aqueous extracts of sorghum and sunflower were applied on the seed of Phalaris minor and wheat and the parameters like germination percent, relative germination ratio, speed of germination, mean germination time, days to 50% germination were calculated. In all the calculated parameters it was found that the aqueous extracts of both sorghum and sunflower are highly allelopathic to Phalaris minor and they have a very little effect on wheat. | Allelopathic potential assessment of sorghum and sunflower on germination characteristics of Phalaris minor and wheat
