Radha Prasanna has made significant and pioneering contributions through a strong multi-disciplinary focus and team work with more than 36 years of research experience in microbiology. Her major inputs to agricultural microbiology have been towards diversifying the role of cyanobacteria across crops and their significant role in enhancing yields and fortification, including grains /produce and enriching soil with macro/micronutrients across diverse crops and as biocontrol agents against phytopathogenic fungi in vegetable crops. She has developed several effective novel microbial multi-species and multifunctional biofilm formulations which provide nitrogen savings and stimulate growth and yields. In-depth analyses of plant-cyanobacteria interactions, as seed dressings, soil application and as foliar/soil drenches and their role in modulating the plant-soil microbiome of crop plants. She has optimized nursery potting mixes technology using cyanobacterial amendment for use in protected cultivation towards disease suppression, soil health restoration and nutrient management in vegetables and flowers.
