Q = St × Sm × I / 360


Q = discharge of 1 sprinkler in l/s


Sm = spacing between the lines


St = spacing between two sprinklers

Crop yield and productivity?

Crop yield = Yield in Quintal/Ha or Tonnes /Ha


Productivity = Crop yield per mm of water applied.

a) The infiltration capacity of the soil(b) The prevailing wind velocity


wind velocity


wind velocity (c) The quantity of water available(d) Sprinkler irrigation
