    Abstract

    Screening of Rhizobium of Sesbania bispinosa, a legume weed from rice growing areas of Kamarajar District, Tamilnadu was done. About 650 plants were uprooted, rhizobia were isolated and they were tested for nitrogenase activity. Out of these the most highly positive isolate, on the basis of nodulation data and nitrogenase activity, DMB R 001 @ DMB R 002 were selected and studied further for vasious climatic factors including different pH, temperature and salinity. The observations indicated that the strains could grow well with the wider temperature range of 28-44o C salinity range of 0-600 milli molar and pH of 4-11. These results showed that the strains could harvest a good amount of N2 for legumes in soil
