Knowledge of plant metabolic processes is essential to have a clear insight about the ‘Science’ involved in agricultural. Realizing this need a separate department of Plant Physiology (rechristened as Crop Physiology) was carved out from agricultural botany in the year 1965. Since then the department has grown considerably. Post-graduation (M.Sc (Ag)) (Plant Physiology) was initiated in the year 1986-87 and later on the Ph.D. programme was also started in the year 2010-11. So far, 74 M.Sc students and seven Ph.D. students were passed out of the department.

The department maintains greenhouse facility and a well-equipped laboratory catering the needs of P.G students of parent department and other departments also. A separate new P.G. laboratory was established in the year 2013. Further, the department also has a well-maintained greenhouse (Crop Research) facility.
