Abstract

Tomato plants grown in sterilized soil applied with Pseudomonas fluorescens grown on Jatropha cake resulted in highest recovery of P. flourescens from soil. Combined application of two bio-agents in the rhizosphere of tomato in sterilized soil resulted in comparatively lower recovery of P. fluorescens and Trichoderma harzianum but was found better for root growth, shoot growth and fruit yield enhancement than their single application. Combined application of bio-agents grown on any of the cake to the sterilized soil resulted in “three time” increase in root length, 1.5 times increase in shoot length and “five time” increase in fruit yields of tomato crop.

 

Key words: Compatibility, Pseudomonas fluorescens, Trichoderma harzianum root length, shoot length and yields of tomato crop.
