Effect of plant growth promoting rhizobacteria on soil microbial load and nodulation at different growth stages in Clitorea ternatea L. under irrigation condition

Abstract

A field experiment was conducted to assess the Effect of Plant Growth Promoting Rhizobacteria on soil microbial load and nodulation at different growth stages in Clitorea ternatea L. under irrigation condition at College of Horticulture, UHS campus, GKVK Post, Bengaluru during 2016-2017. The experiments were comprised of ten treatments and they were replicated thrice in RCBD. The maximum Bradyrhizobium japonicum (13.75 CFU) and Pseudomonas fluorescence population (14.18 CFU) was recorded with seed treatment of Bradyrhizobium japonicum + Pseudomonas fluorescence with application of full dose of RDF and number of nodules (3.51, 19.14 and 26.15), fresh weight of nodules (136.69 mg, 860.67 mg and 1196.40 mg) and dry weight of nodules (50.21 mg, 284.40 mg and 563.06 mg) are found maximum at 30, 60 and 90 days after sowing respectively, with seed treatment of Bradyrhizobium japonicum + Pseudomonas fluorescence with application of full dose of RDF.
