Effect of plant growth promoting rhizobacteria on soil microbial load, chemical properties of soil and economics in Clitorea ternatea L. under rain fed condition

Abstract

A field experiment was conducted to assess the Effect of plant growth promoting rhizobacteria on microbial load, chemical properties of soil and economics in Clitorea ternatea L. under rain fed condition at College of Horticulture, UHS campus, GKVK, Bengaluru, during 2016-2017. The experiments were comprised of ten treatments and they were replicated thrice in RCBD. The maximum Bradyrhizobium japonicum (13.17 CFU) and Pseudomonas fluorescens population (11.58 CFU) was recorded with seed treatment of Bradyrhizobium japonicum + Pseudomonas fluorescens with application of full dose of RDF and higher nitrogen and phosphorous content of the soil (242.16, 51.46 kg ha-1 respectively) was obtained with seed treatment of Bradyrhizobium japonicum + Pseudomonas fluorescens with application of full dose of RDF. Whereas, the potassium in soil was found higher (170.82 kg ha-1) with control. The higher B: C Ratio was found with seed treatment of Bradyrhizobium japonicum + Pseudomonas fluorescens with application of full dose of RDF.
