Effect of Nitrogen Fixing Bacteria Azotobacter and Azospirillum on the Growth of Rosa Polyantha
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2014, Vol 1, Issue 7
Abstract
Nitrogen fixation is an important biological process where atmospheric nitrogen is converted into ammonia, which can easily be assimilated by the plants. In the present study broth containing N-fixing bacteria Azotobacter and Azospirillum were applied on rose plant (Rosa polyantha) and its effect on the growth and yield of rose plant was studied. A pot experiment was conducted to study the effect of two bacterial inoculants Azotobacter, Azospirillum and their combination on growth and yield of rose. The result showed that application of mixed inoculants (Azotobacter + Azospirillum) produced significantly maximum yield with respect to plant height, number of leaves, number of branches per plant, high chlorophyll and protein content, when compared with single inoculation and control. Azospirillum inoculation resulted in higher growth and yield parameters in comparison to Azotobacter inoculation. From this study, it can be concluded that the biofertilizer inoculation of mixed inoculants gives maximum yield of rose plant as compared to single inoculation and control.
