Pheno-morphological and biochemical characterization of root nodules and associated root nodulating bacteria from <i>Pongamia pinnata</i> (L.) Pierre in the arid regions of India.

ABSTRACT:

Introduction

Pongamia pinnata (L.) Pierre is a resilient leguminous tree valued for its biofuel potential and ability to flourish in marginal soils due to symbiotic nitrogen fixation by root-nodulating bacteria (RNB). Understanding the phenomorphological, soil, and biochemical characteristics of its associated RNB is essential for enhancing productivity in arid regions. This study aimed to characterize RNB isolates associated with P. pinnata and assess how soil properties and nodule biochemistry influence plant growth in the arid ecosystems of western Rajasthan.

Methods

Twenty RNB isolates (PP-01 to PP-20) were collected from P. pinnata nodules across arid sites. Rhizospheric soil samples were analysed for physico-chemical parameters, including pH, EC, o
