The brinjal seeds were bio primed with liquid biocontrol agent Psuedomonas fluorescens in five different concentrations viz., 5, 10, 15, 20 and 25% by adopting seed to solution ratio of 1;1 by volume by volume basis for 6 h (already standardised) and evaluated for seed and seedling quality characters along with hydroprimed and nonprimed seed. The results revealed that, seeds bioprimed with P. fluorescens at 15% concentration for 6h increased the speed of germination by 12.8 percent, germination by 10 percent, root length by 11.1 percent and shoot length by 29.4 percent over nonprimed seeds. The percent increase over nonprimed seed for the drymatter production and vigour index was 15.1 and 30.3 percent, respectively.
