Seed yield, its contributing characters and subsequent quality of Barley (Hordeum Vulgare L.) as influenced by the pre-sowing microbial seed inoculation

To examine the effect of pre-sowing seed inoculation either singly with Pseuodomonas fluorescens and Trichoderma harzianum or combination with both bio-inoculants @ 4g, 6g, 8g per kg seed of singly or @ (2+2) g, (3+3) g, (4+4) g/kg seed with mixture on growth yield and subsequent seed quality of barley. The results revealed that the effect of pre-sowing seed bio-inoculation was significant to each and every treatment over un-inoculated control for the field germination, root length, plant height, ear length, number of seeds per ear, 1000-seed weight and seed yield/ha under field trial and also for subsequent seed quality i.e. germination, radicle, plumule and seedling length, fresh and dry weight of seedlings and vigour index (I&II) under laboratory experiment. Seed yield and its contributing characters as well as subsequent seed quality were increases as the amount of P. fluorescens and T. harzianum increases from @ 4 to 8 g/kg either singly or in combination of both bio-inoculants. The bio-inoculants mixture showed greater influence on seed yield and quality over seed treated either with P. fluorescens and T. harzianum and both bio-inoculants mixture @ (4+4) g/kg seed had maximum influence on characters studies under field as well as laboratory experiment.
