Azotobacter chroococcum\'s potential for use in crop production and the impact of air pollution on leaf chlorophyll content


Frank P Tverdek*

Comparative investigations have been conducted in the current inquiry to determine the impact of air pollutants produced by industry and automotive exhaust on the chrorophyll content of leaves. Azadirachta indica, Nerium oleander, Mangifera indica, and Dalbergia sissoo leaf samples were gathered from locations that may have greater and lower air pollution levels. Chlorophyll a, Chlorophyll b, and carotenoids were measured as photosynthetic pigments. leaves of plants growing in more polluted areas have less photosynthetic pigments than those growing in unpolluted or less polluted areas. The importance of Azotobacter chroococcum spp. in crop production has emerged via research, as has its role in plant nutrition and soil fertility. A significant increase in crop output has been seen in agriculture due to the potential use of Azotobacter chroococcum in research studies as a microbial inoculant through production of growth compounds and their effects on the plant. Because they are soil bacteria, Azotobacteria produce auxins, cytokinins, and GA-like compounds, which are the main factors regulating the accelerated growth. The closely related higher plants are impacted by these hormonal chemicals, which come from the rhizosphere or root surface. Finding appropriate partners, such as a specific plant genotype and a specific Azotobacter strain, is required to ensure the high efficacy of inoculants and microbiological fertilisers (Piccardi M et al., 2004).
