The factors affecting the duty of water in irrigation are as follows: 

i. Soil Characteristics: 

If soil of canal bed is porous and course grained, → more seepage loss, → low duty 

If soil of canal bed is alluvial, → less seepage loss, → high duty

 

ii. Climatic condition: 

High temperature, → more evaporation loss, → low duty 

Vice versa.

 

iii. Rainfall

Rainfall during crop period is sufficient → more duty

 

iv. Type of crop 

Water requirements for various crops are different. 

Varies from crop to crop.

 

v. Topography of agricultural land 

Uneven land → low duty 

Plain land → High duty

 

vi. Method of ploughing 

Ploughing by bulls → Low duty 

Ploughing by tractors → High duty

 

vii. Method of irrigation

Perennial Irrigation system → high duty 

Inundation Irrigation system → low duty. 

 

viii. Method of cultivation

Correctly ploughing up to specified depth → Soil holds more water → high duty
