Abstract

It is known that P. niruri is a member of family Euphorbiaceae. In the previous studies the allelopathy, leachtes of P. niruri have been prepared from root, stem and leaf and their chemical changes have been also recorded. Further studies have been carried out to observe the effect of these leachates on seed germination and seedling growth of rice crop plant. It was observed that there is change in pH value of stem, leaf and root leachtes from first day to six day and different dilutions. The pH value of water is significantly affected by allelochemicals of root during the continuous flow of water and this crop present field to be effected by the water of consisting changed pH value. The effect of these weed on the seed germination and seedling growth of rice crop have been studied and it was found that leachates treatment inhibits the seed germination and seedling growth of crop plants. In the allelopathic study we can show that the root extract of P. niruri Linn. is more effective that of stem and leaf extracts.
