ABSTRACT: The present investigation has been made to compare "the effect of seaweed fertilizers and vermiwash on seed germination of Cyamopsis tetragonoloba (Cluster bean or Guar)". Seeds were soaked in various concentrations (0.5%, 1%, 2%, 3% and 5%) of seaweed fertilizers (liquid  & paste) and vermiwash separately at different time periods (30, 60 and 120 minutes). After 7 days, the seeds were analyzed for their germination capacity, shoot length & root length. The study infers that seaweed liquid fertilizers with the concentration of 1% showed maximum seed germination (100%) and the optimum shoot and root length was recorded as 6.04cm and 3.34cm respectively soaking whereas in seaweed paste fertilizers, 3% showed maximum seed germination 100% with the shoot & root length of 6.58cm and 3.46cm after 120 minutes. Also, the vermiwash with the concentration of 0.5% showed maximum seed germination (100%) and the optimum shoot and root length was recorded as 6.32cm and 3.52cm respectively after 30 minutes soaking.
