2.1 Short description of the Technology

Definition of the Technology:

Drip irrigation using polyethylene sheeting and intermittent cloth strips.

2.2 Detailed description of the Technology

Description:

Drip irrigation with polyethylene film was used in areas with extreme conditions who have poor irrigation water available for the cultivation of vegetables. The polyethylene film covers vegetable patches and is filled with water. Every plant is watered with the use of cloth strips which soak up the water. Roots of the plants are watered on a regular basis.

Purpose of the Technology: South of Khatlon lacks water, which is mainly used to irrigate the cotton plantations. Land users stored water in the tanks and used it for drip irrigation. The overall goal of the technology is to use water efficiently, to reduce evaporation and to prevent soil erosion. The technology is used to grow vegetables and tree plants.

Establishment / maintenance activities and inputs: Ploughing, digging patches, planting the plants, covering the patches with polyethylene sheet, filling with water. Every plant is watered with the use of cloth strips which soak up the water. This technology requires polyethylene sheeting, and cloth strips for drip irrigation.

Natural / human environment: Annual plants are grown under extreme climatic and unpredictable weather conditions, in saline soils and with poor irrigation water available
