A drip irrigation hose includes a hose body formed of a single sheet of overlapping material. The hose includes a primary fluid chamber extending longitudinally along the hose formed within the hose body. The hose includes a plurality of secondary fluid chambers serially disposed along the hose. The secondary fluid chambers each include a plurality of inlets formed in the hose body between a first portion and the primary fluid chamber for receiving fluid from the primary fluid chamber. The secondary fluid chambers each includes a second portion including a plurality of embossed regions formed in the hose body, and an outlet formed in the hose body adjacent the second end. Each of the secondary fluid chambers includes a pair of ribs longitudinally disposed along the first and second portions for forming side walls of each of the secondary fluid chambers.

A constant-flow drip irrigation tape hose includes a primary flow path communicating water along the length of the hose. A secondary drip-flow path leads from the primary flow path to an emitter site outwardly of the hose. The hose is formed with a pair of variably spaced apart walls at least one of which is formed with a continuously-open channel defining part of the secondary flow path. A second variable-area part of the secondary flow path is defined by radial spacing of the pair of walls from one another. At least one of the pair of walls is responsive to internal water pressure in the primary flow path to open and close the variable-area part of the secondary flow path in response, respectively, to decreasing and increasing water pressure in the hose. A plurality of emitter sites are spaced regularly along a length of the hose. Consequently, the hose has at least one pressure range within which it provides a nearly constant drip-flow irrigation rate to plants of a row crop as the water pressure within the hose decreases over the length of an elongate run of hose.
