The efficacy of different pesticide, fungicide and biofertilizers combinational seed treatments was tested for vigor and viability in laboratory and field experiments using fresh, one year old and two years old seeds of barley. The seeds were treated with chlorpyriphos, vitavax, Azotobacter and Phosphorus solubilizing bacteria (PSB) in different combinations and their seed quality was assessed by recording germination and seedling vigour related parameters. Results revealed that seed treated
with Azotobacter + PSB recorded maximum enhancement in seed quality as compared to control regarding all the parameters in fresh as well as old seed lots of barley. However, treatment of chlorpyriphos + vitavax + Azotobacter + PSB showed negative impact and resulted in a significant reduction in all the parameters. In general, it was concluded that application of biofertilizers as seed treatment results in better performance in terms of germination and vigour, while, the insecticide chlorpyriphos has a negative impact on seed germination if applied alone or in combination with other chemicals.
