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.
Deoiled cakes of Neem and Jatropha served as source of diversified nutrition for Pseudomonas flourescens when used as substrate for mass culturing of antagonist. The present investigation were undertaken to test the suitability of neem and Jatropha cakes for liquid Concentration and longevity of Pseudomonas flourescens in vitro. Increasing the dilution of stock of initial inoculums resulted in decrease of total viable counts of Pseudomonas flourescens was comparatively highest population (64.67×10 5 ) and (201.67×10 5 ) lesser after 15 days than after 7 days of inoculation on Neem and Jatropha cake concentration respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
