Title: Evaluation and improvement of a low-head drip irrigation system to be used by small scale farmers in Bangladesh
Abstract: A study was undertaken to evaluate the low-head drip irrigation system introduced by ARFA Engineering in Bangladesh. The experiment was conducted at the Hydraulic Laboratory in the Department of Irrigation and Water Management, Bangladesh Agriculture University, Mymensingh. A timber framework (10.2 m long) experimental layout was assembled to support the drip lines at various land slopes (0 to 3.03%). Drip lines were positioned along the timber framework. A mini tank was used as water source and was placed at varying heads (0.5-1.0 m) from which water was allowed to flow through the rubber pipes at different emitters along the lateral lines. To collect the emitter water, catch cans were placed along the drip line directly below the emitters. Data were collected at varying water head, land slope, lateral length. Varying water head, land slope and lateral length affected the result. The experiment showed that for different heads and slopes, EU values are < 70% and FV values >20% and a CV value > 0.15 indicating that the performances of this (ARFA) drip irrigation system is very poor and not acceptable to irrigate crops in the field.
