Drip irrigation in coconut

Root zone of coconut for moisture absorption is concentrated in a circular area of 200 cm radius around the base of coconut tree up to a depth of 100 cm. Irrigating coconut trees by a set of four drippers set equidistant in a circle 100 cm away from the base of the tree and discharging water at the rate of 30 l/h for 2.5 h with a irrigation frequency of 8 days can maximize the wetting area of soils in the effective root zone of coconut.
