Dr Karthikeyan, A.
Working as Scientist F in the Institute of Forest Genetics and Tree Breeding, Coimbatore India. Undertook research on Frankia (N fixing bacteria) for improvement of Casuarinas, Rhizobium on leguminous tree crops and also on other Nitrogen fixers such as Azospirillum and Azotobacter.
- Bio fertilizers
- Forest pathology
Current N-related Projects:
- Identification of superior strains of Rhizobium and AM fungi for improving planting stocks of Pterocarpus santalinus
