In Today’s agriculture trees and plants plays vital role in ecosystem and it is an essential part to lead healthy human life. Various aqueous leaves extracts of Morinda tinctoria were tested for the potential exhibitory and inhibitory effects on sorghum. There were four extraction methods viz., i) Fresh leaf extract ii) alcoholic extracts iii) decoction at (1:4) and (1:6) each at 5 and 10 percent concentrations and distilled water served as control. Seed germination of sorghum was significantly exhibited by fresh leaf extracts at 5 per cent. Radicle, plumule growth, seedling vigor index I and II and other germination attributes were also increased by fresh leaf extract. It is assumed that optimum pH, EC of fresh leaf aqueous extract and also the presence of some growth promoting phytochemicals. It was at par with decoction (1:6) at 5 percent. The highest inhibition was noticed with alcoholic extract at both concentrations. It is found to have better efficiency in extracting the bioactive compound present in the tree leaves of Morinda. Further, instead of using an alcohol, it is natural way of extraction and it could be adopted easily and followed without any extra input or instrumentation or tool.
