Abstract: This article provides an overview on role of efficient native rhizobia isolation and symbiotic nitrogen fixation by legumes. The protein element in legumes; which is among the richest source of protein worldwide relies mostly on nitrogen (N2). Symbiotic nitrogen fixation is the base for source of nitrogen in legumes. Legume rhizobium symbiosis proves more effective when the rhizobial species works efficiently under particular or sometimes extreme environmental conditions. Therefore the acclimatisation of native rhizobia to native environment for better legume rhizobia symbiosis, thereby better nitrogen fixation and thereby a more better protein source for our population needs to be isolated. The extreme environmental conditions viz. salinity, acidity, high temperature, drought and flood often stands as the major causes for yield reduction in pulses due to reduction in growth and metabolism of rhizobial species. Hence, screening of native rhizobia on their efficiency basis by various physical, biochemical as well as molecular characteristics and application of these efficient native rhizobia to legumes will improve the legume yield as well as the protein concentration in them, thereby leading to a sustainable symbiotic relationship between legume rhizobia.
