Abstract: An experiment comprising bio priming with Trichoderma viride @ 5g/kg seed, Pseudomonas fluorescence @ 5g/kg seed and solid matrix with sand was conducted in 3 genetically diverse and promising cultivars viz.,NDR-2064, Shusk Samrat and Shabha Sub-1of rice for 12 and 16 hrs during Kharif 2017 and 2018 in order to explore their possibilities for seed enhancement. All the priming treatments showed significant enhancement in seed germination (%), speed of germination, root length (cm), shoot length (cm), seedling length (cm) and vigour index in all the varieties in comparison to their respective control. The bio priming was appeared superior as compared to solid matrix. Thus, the seed priming with either Pseudomonas fluorescence or Trichoderma viride @ 5g/kg seed and solid matrix with sand for 12/16 hrs depending upon the genetic architecture of the trait/ seed could be exploited as cost effective/economic, non-toxic and eco-friendly sources for enhancing the seed quality parameters in rice.
