Tubewell is a device for obtaining water from beneath the ground, consisting of a wrought-iron pipe armed with a sharp point, and having a series of perforations at the lower end above the point. The development of tube-well irrigation, supported by investment in electrification and credit provision, has been the main driving force behind irrigation expansion and productivity improvements over the past few decades, particularly in the northwest.
