Pea (Pisum sativum L.) having capability to harbor plant growth promoting rhizobacteria.The experiment was conducted to examine, the effect of plant growth promoting rhizobacteria (PGPRs) single or in addition with L-tryptophan, a precursor of auxin on production of Pisum sativum L. Experiment was conducted at the vegetable area, Delma Island United Arab Emirates. Seeds of Pisum sativum L.) cultivars viz. Meteor, Alina Pak, Climax and Pea- 2009 were treated with FF-34 (Pantoea sp.), (Burkholderia phytofirmans), FF-34+L-Tryptophan, PsJN PsJN+L-Tryptophan, water (positive control) whereas untreated seeds assisted as control. Data were collected concerning various parameters such as plant emergence percentage, plant height, branches number plant-1, chlorophyll content, days to 1st flowering, days from flowering to 1st pod maturity, number of pods per plant, pod length, seeds number pod-1, fresh and weight of dry plant, harvest index and hundred seed weight. Pea varieties Pea-2009 and Climax excelled over all other varieties for some traits. Among seed treatments FF-34 exhibited better results for maximum parameters. Results signify the role of PGPRs in Pea growth and productivity.
