Exploring the Significant Function of Nitrogen - Fixing Cyanobacteria in Rice Crop Improvement

E. Komala [2]


Abstract: The primary focus of this research is to analyse the significant part that nitrogen - fixing cyanobacteria play in boosting the development and production of rice crops. When it comes to agricultural soils, nitrogen, which is a necessary component for plant development, is frequently a factor that is restricting. To alleviate nitrogen deficits in rice fields, cyanobacteria, which are well - known for their exceptional capacity to fix nitrogen in the atmosphere, provide a solution that is both sustainable and environmentally beneficial. Unraveling the complex mechanisms that nitrogen - fixing cyanobacteria employ to contribute to the development of rice crops is the primary objective of this research. The study investigates the symbiotic interaction that exists between cyanobacteria and rice plants using a series of controlled experiments as well as field trials. In the process of colonizing the rhizosphere, cyanobacteria develop a mutually advantageous partnership with rice plants by supplying them with bioavailable nitrogen in return for root exudates generated by the rice plants. In addition, the research investigates the influence that this nitrogen - fixing capability has on the physiological and biochemical characteristics of rice plants. The improvement of nitrogen content, chlorophyll production, and general plant development are all topics that are investigated in this study. The findings provide light on the potential of cyanobacteria as a natural and sustainable supply of nitrogen, therefore lowering the reliance on synthetic fertilizers and minimizing the environmental consequences that relate to nitrogen runoff. Acquiring knowledge of nitrogen - fixing cyanobacteria and making use of their advantages is becoming increasingly important as worries about food security and sustainable agriculture become more widespread across the world. The insights that were gathered from this research led to the development of environmentally friendly agricultural techniques that increase rice crop yields while simultaneously promoting environmental sustainability. The research highlights the relevance of using the intrinsic biological nitrogen - fixing capabilities of cyanobacteria as a viable technique for the development of rice crops in a sustainable manner.
