Abstract
Allelopathy is the direct influence of a chemical released from one plant on the development and growth of another plant. Chemicals with allelopathic potential exist invariably in all plant tissues including leaves, flowers, stems, rhizomes and ischolar_mains. Processes such as volatilization, ischolar_main exudation, leaching and decomposition of plant residues release them into environment. Accumulation of more allelochemicals from weeds in fields causes soil sickness, reduced nitrification and nutrient uptake resulting in loss of crop yield. The present study has been conducted to examine the allelopathic effects of Grangia maderaspatena Frosk. on seed germination of three varieties of rice, i.e., Aiswarya, Kanchana and Harsha.
