Crop physiology deals with the study of how crop plants develop, grow, and respond to their environment at the cellular and biochemical level. It examines topics like seed physiology, optimal seedling growth, plant population, harvest index, the mode of action of herbicides, nutriophysiology, photoperiodism, plant growth regulators, water use efficiency, and post-harvest physiology. Understanding crop physiology is important for agriculture as it allows for improving areas like withstanding biotic and abiotic stresses, maximizing yields, and reducing post-harvest losses in India's predominantly rainfed agricultural system.

Literal Definition:
In Greek: physis = nature and logos = word ¡°Discourse
on the nature of plants¡±
Definition: Crop physiology deals with the study of
crop plants with its external and internal anatomy is
called as crop physiology.
OR¡°Science of how plants develop, grow, and
respond to their environment at the cellular &

Crop: it is a group of plants grown as a community in a
specific locality and, for a specific purpose.
