Rhizobium is an organism used as bio-fertilizer for raising soybean crop

Rhizobium is a type of bacteria that forms a symbiotic relationship with leguminous plants, such as soybeans. It is commonly used as a bio-fertilizer to enhance the growth and productivity of soybean crops.

What is bio-fertilizer?

Bio-fertilizers are substances that contain living microorganisms which, when applied to plants or soil, promote plant growth by increasing the availability of nutrients. These microorganisms fix atmospheric nitrogen and convert it into a usable form for plants, thus reducing the need for chemical fertilizers and improving soil fertility.

Symbiotic relationship between Rhizobium and soybean plants

Rhizobium forms a mutualistic symbiotic relationship with soybean plants. The bacteria colonize the root nodules of the plants, where they convert atmospheric nitrogen into ammonia through a process called nitrogen fixation. In return, the plant provides the bacteria with sugars and other nutrients necessary for their growth.

Benefits of using Rhizobium as a bio-fertilizer for soybean crops

1. Nitrogen fixation: Rhizobium bacteria have the ability to fix atmospheric nitrogen, which is then used by the soybean plants for their growth and development. This reduces the dependency on synthetic nitrogen fertilizers and helps in reducing environmental pollution.

2. Increased nutrient availability: Rhizobium bacteria also help in solubilizing phosphorus and other essential nutrients in the soil, making them more available to the soybean plants. This improves the overall nutrient uptake and enhances crop productivity.

3. Soil fertility improvement: The presence of Rhizobium in the soil enhances soil fertility by increasing organic matter content and improving soil structure. It also helps in improving water retention capacity and nutrient-holding capacity of the soil.

4. Cost-effective and sustainable: The use of Rhizobium as a bio-fertilizer reduces the cost of chemical fertilizers and promotes sustainable agricultural practices. It is a natural and environmentally friendly approach to enhance crop productivity.

Conclusion

Rhizobium is an organism used as a bio-fertilizer for raising soybean crops. Its ability to fix atmospheric nitrogen and improve nutrient availability makes it a valuable tool in sustainable agriculture. By using Rhizobium, farmers can reduce their dependency on chemical fertilizers, improve soil fertility, and enhance the productivity of soybean crops.

Rhizobium inoculant is used for leguminous crops. Azotobacter can be used with crops like wheat, maize, mustard, cotton, potato and other vegetable crops. Azospirillum inoculations are recommended mainly for sorghum, millets, maize, sugarcane and wheat. Nostoc fix atmospheric nitrogen and are used as inoculations for paddy crop grown both under upland and low-land conditions
Soybean is a legume.t therefore answer is rhizobium..
