An experiment was carried out to know the effect of seed biopriming in tomato under laboratory condition. Tomato (Solanum lycopersicum L.) seeds were subjected to biopriming with plant growth promoting rhizobacteria (PGPR) viz.,Bacillus amyloliquifaciens VB7 and Bacillus licheniformis BSC2 of different concentrations viz.,1%, 2% ,4%, 6%, 8% and 10% for 9hr soaking durations along with hydropriming and nonprimed seed formed the control. The results revealed that seeds bioprimed with Bacillus amyloliquifaciens VB7 6% recorded maximum speed of germination (6.12) seed germination (93%), root length (16.89), shoot length (5.78) and vigour index (2108) than the other treatments.
