1. Introduction – Importance of crop physiology in agriculture.
2. Role and significance of water – diffusion, imbibition, osmosis and its significance, plasmolysis.

3. Definition – field capacity, water holding capacity of soil and permanent wilting point.
4. Absorption of water – mode of water absorption – active and passive absorption and factors affecting absorption.

5. Translocation of solutes – phloem and xylem transport.
6. Transpiration – types – Steward’s theory of mechanism – significance, factors affecting transpiration and guttation – antitranspirants.

7. Mineral nutrition – introduction – criteria of essentiality of elements – macro, secondary and micronutrients – soil less culture – sand and hydroponics.

8. Mechanism of uptake – physiological role of nutrients.
9. Foliar diagnosis – nutritional and physiological disorders – foliar nutrition- fertigation
10. Photosynthesis – requirements of photosynthesis – light, CO2, pigments and H20.
11. Mechanism of photosynthesis – light reaction – cyclic and non cyclic photophosphorylation – Red drop – Emerson Enhancement Effect.

14. Photorespiration – photorespiration process and significance of photorespiration.
15. Respiration – Glycolysis, TCA and Pentose Phosphate Pathway.
16. Oxidative phosphorylation – differences between oxidative phosphorylation and photophosphorylation. Respiratory quotient and energy budgeting in respiration.

17. Factors affecting respiration – difference between photorespiration and dark respiration – role of respiration.

18. Protein and fat synthesis.
19. Photoperiodism – short day, long day and day neutral plants – phytochrome. Role of phytochrome in flowering and regulation of flowering.
