Abstract
Groundnut (Arachis hypogea L.) is a highly demandable leguminous crop, which is rich nutritious and regular consumed on various processing ways and it could be enhance the soil fertility in tropical and subtropical regions. However, this crop production was low due to ecological and commercial factors. In ecological aspects, several alternatives were suggested by the researchers to improve the groundnut productions, among the alternative methods bioinoculants are suitable to ecological and social feasible. In the present study, two diazotrophic bacteria of Rhizobium and Azospirillum were treated with groundnut plants under nursery condition on individual and combined applications. The treated plants were harvested in different time intervals like 30, 60 and 90 days after inoculations. The harvested plants morphometric, nodule number and dry weights, leaf area and chlorophyll contents, soil and plant tissue nitrogen content, leghaemoglobin content and formation of nuts numbers were recorded. The present study results were suggested to possibility by better chances of survival and yield in the field conditions.
