Interactions involving plants roots
Rhizoplane – The surface of the plant root, root hairs present large surface area (>6m2 for an average wheat plant). Only 4-10% of the Rhizoplane is in direct contact with soil microbes.
Rhizosphere – The area of the soil directly infuluenced by plant roots (extremely variable). Soil that remains after shaking off roots.
Rhizosheath – Some plants excrete a mucous-like material that cement sand grains together around the root. Most common in dry soils
R/S radio - indicates the importance of the root system to the microbial community.
  • R - The number or biomass of microbes in the rhizoshphere.
  • S - The number or biomass of microbes in the root-free soil.
  • R/S typically between 5 & 20, can be >100
In the rhizosphere(relative to root- free soil)
  • abundance of Gram-negative rods is higher.
  • abundance of Gram- positive rods and cocci is lower

Our Laboratory is engaged in research on various aspects of Biofertilizers and their applications.
In the first phase of study, Mycorrhizal was used as biofertilizer. Studies were conducted in order to exploit potentiality of mycorrhizal fungi in reclamation of saline wastelands of Indian Thar desert particularly Luni and Pachpadra basin. For this purpose native as well as exotic plant species were transplanted in saline areas with the help of mycorrhizal fungi. It was very interesting to note that an exotic plant species namely Acacia colei (a native of Australia) was successfully transplanted in these saline belts. Mycorrhizal fungi helped the plant for its survival and establishment under natural saline wasteland habitats.
In the second phase of study joint application of different biofertilizers were made to improve nutrient content and productivity of some leguminous plants of this region. Biofertilizers like Rhizobium, Azatobacter and Pseudomonas along with mycorrhizal fungi resulted in increased nodulation and productivity of common legumes of this region.
