Choose the correct answer
By flooding the entire field
Directly to root zone via emitters at low pressure — highest efficiency (90–95%), minimal losses
By spraying from above the crop canopy
By ponding in furrows only
Correct Answer
B. Directly to root zone via emitters at low pressure — highest efficiency (90–95%), minimal losses

Drip (trickle) irrigation: water delivered directly to root zone through emitters at low pressure (0.5–2 bar). Application efficiency 90–95% (very high — negligible evaporation and runoff). Suitable for fruit orchards, vegetables, plantations. Requires filtered, clean water to prevent emitter clogging. Used in water-scarce regions.
