An improvement in allelopathic potential in rice will have a great impact on both low-input and high-input management *** alone is not likely to replace other weed control practices,but it surely functions as a component of integrated weed management *** reduced use of herbicide over time will provide significant economical benefits to farmers and will also reduce adverse effects on the environment.

The negative impacts of commercial herbicide use on the environment make it desirable to diversify weed management *** investigations have been attempted to exploit allelopathy of plants for weed control purposes in a variety of agricultural settings,since allelopathy is regarded as the direct influence of an organic chemical released from one living plant on the growth and development of other plants.

*** sterilization and germination *** seeds were surface sterilized in 70%ethanol for 15 min,2%NaClO added 1 drop of Tween 20 for 25 min and then rinsed in four to six volumes of sterile water. Approximately 200 seeds were placed in round Petri dishes(90 mm×25 mm) containing 0.1% Noble *** plates were sealed with parafilm,placed at 4℃for 2 days to stimulate germination,and then transferred to a 16℃growth incubator under a light condition. Germination occurred 10-14 days after sowing.
