Development of host specific nodulation by indigenous rhizobia in five agro forestry tree species

Abstract

Nodulation in legumes provides a major conduit of available nitrogen into the biosphere. 25 geo-specific rhizobium isolates in relation to five legume plant varieties were tested with combinations under gnotobiotic conditions for improving nodulation and plant growth through inoculation in field trials for the unraveling and amelioration of sustainable plantations in barren, polluted and agriculture soils. Interestingly, strains from Bhadrachalam forest were found to be highly host specific for Albizzia lebbeck, Sesbania grandiflora and Pongamia pinnata and strains from Jakaram and Kothagudem forests were shown host specific for Gliricidia maculata and Acacia nilotica, respectively. This method can employ across the country for green revolution.
