Field trials were conducted during the years 2009-2010, at a private farm in Puttaparthi, Anantapur District, India, to study the effect of biological agents as effective seed treatment substitutes over commonly used chemicals on ground nut plants,Arachis hypogea. The biological agents (BA) tested for this purpose involved, BGA,Azotobacter and Azospirillum. Seeds were treated prior to sowing with each of these 3 agents both individually and in combination. Commonly used chemical for seed treatment, was used as the control. The treated seeds were sown on the soil combination, 3:1 FYM: NPK. BGA proved to be the best among the 3 biological agents. The effect of Azotobacter was marginal when used alone. However, the same was augmented in the presence of BGA. Azospirillum seemed to have a negative effect on growth and yield, when applied alone and in combination with BGA.
