An investigation was undertaken by taking seed samples of maize in laboratory and green house of the AICRP on Seed Technology Research, NSP (crops), at Department of Seed science and technology, Ouat, Bhubaneswar, to find out the best bio control agent using seed priming technique, under laboratory and green house condition. The experiment material consists of three biocontrol agents seven treatment with four replications that is T 1-Seed priming with Trichoderma viride(10%), T 2- Seed priming with Trichoderma viride (20%), T 3- Seed priming with Trichoderma harzianum (10%) for one hour, T4-Seed priming with Trichoderma harzianum (20%), T5-Seed priming with Pseudomonas fluorescens (10%), T6-Seed priming with Pseudomonas fluorescens(20%), T7-untreated /control with 12 hours of soaking. The treatments were also evaluated for their effect on seed quality parameters like seedling length, Field emergence seedling dry weight, seedling vigour index. The occurrence of seed rot and seedling infection was also observed in laboratory and green house condition. Seed biopriming with T. harzianum 10% for 12 hours was found best in increasing the germination, seedling length, seedling dry weight, SVI-I, SVI-II by 94%, 27.85cm, 0.316g, 2564.4 & 29.71 respectively and reducing the seed rot and seedling infection by 82% and 78% respectively. Under green house condition also, seed biopriming with T. harzianum 10% for 12 hours was best with highest field emergence 88%, plant height 28.6cm, seedling length 34.9cm, dry weight 2.75g, SVI -I 3070.4, SVI-II 241.9 and minimum seedling blight 10.3% and seedling damping off 11.25%.
