ABSTRACT
Allelopathic potential of Tinospora cordifolia (Willd.) Hook. f. and Thoms was tested on seed germination and seedling growth of Brassica campestris L. Brassica oleracea L. Oryza sativa and Zea mays L. Aqueous extract of Tinosporacordifolia leaveswas made by soaking shade-dried leaves in distilled water for 24 hours at room temperature. Sterilized seeds were subsequently treated with extracts at concentrations of 2%, 4%, 6%, 8%, and 10%. Every day, the seeds that germinated were counted to determine the average germination time. It has been discovered that when concentration increases, germination takes a significant amount of time. Additionally, it was shown that germination percentage, root length, shoot length, and seedling vigour value were reduced at concentrations higher than 2% as compare to the control group. The strongest growth inhibiting effect on seedlings growth was demonstrated by the 10% aqueous extract of leaves of Tinosporacordifolia extract demonstrated potent inhibitory effects on seed germination and seedling growth in the current study.
