Abstract:

Emitter is the critical component of drip irrigation system through which water is delivered precisely to the plants. The moisture level assessment and its distribution play an important role in designing of drip irrigation system. A laboratory study was undertaken to study the effect of discharge rate of emitters on soil moisture distribution pattern in the sandy soil of Arunachal Pradesh, (India). Vertical front advance was measured to be more in 2 lph emitters as compared to 4 and 10 lph capacity emitters. Horizontal spread was more in 10 lph emitters as compared to 2 and 4 lph emitters. In 2 lph emitter, the rate of vertical water movement below the emitter was higher than the rate of lateral movement as compared to 4 and 10 lph emitter. As the emitter discharge increased the lateral spread of the moisture content was also increased in case of 4 and 10 lph capacity emitter as compared to 2 lph capacity emitter.
