A field examination was directed at the trial field of Kerala Agricultural University during March to May 2014; this study explored the Allelopathic possibilities of Acacia auriculiformis on the seed germination and seedling development of rice (Oryza sativa L.). This trial examination was led in 2 A- 3 A- 5 factorial arrangement based on CRD with five treatments. Rhizosphere soil and top soil were gathered from the woodlots and 3-5 year old Acacia stand separately, though, fresh acacia leaves were utilized for inundating field soil with cold extract and field soil mulched with dry leaves of acacia embrace five treatments. Statistical analysis (ANOVA, P = 0.05) uncovered that the treatments brought a respectable inhibition in the germination of rice seeds, the seedling shoot lengths and vigor indexas compared to the control. However, there were no significant differences in the root length and dry matter weight of rice. The maximum inhibitory effect was observed in field soil mulched with dry leaves of acacia with inhibition on the germination, seedling length, dry matter production and vigor index. Root length was more delicate to the treatments than seedling length. The results from this study firmly recommend that allelopathy may be a conceivable technique controlling the timing of rice germination and seedling formation.
