The department of Botany was established in the year 1967. Currently, the department has four professors, one reader and three lecturers excluding one on leave. About 600 research papers and scientific articles have been published in national and international journals of repute. The department has produced more than 70 Ph.D. students so far. The department has successfully completed several research projects. Major areas of research in the department include physiology and microbial biochemistry, genetics, experimental botany, plant and microbial ecology, system analysis and plant pathology. Many faculty members visited abroad for advanced training in their respective areas and for participation in international conferences/congresses. Besides they have held membership of various national and international association and societies. The department maintains a library for students and a small Botanical Garden. At present there are several full-time research scholars working on different areas of research and they are obtaining scholarships from the university/other agencies. Many of our students passed NET/SET/GATE examinations successfully and have completed research from this department. A large number of our students are occupying teaching and other positions in the country. The department was chosen to organize refresher course in Botany thrice on a national level. There are several eminent personalities from various other universities/institutions who have been visiting this department and also delivered lectures useful to our students time and again. The department has very healthy academic atmosphere and a congenial teacher-taught relationship.
