The site is located in a semi-drought zone subject to acute shortage of water resources in summer period and land degradation

• Located in the Varzob River Basin (right-bank tributary of the Kafirnigan (Kofarnihon) River);
• Valley section of the Kafirnigan River Basin (river catchment area);
• Deep (below 5 m) ground water occurrence;
• Other peculiarities: middle loamy soils.

Extremely low water availability (supply) of pastures; the quantity of cattle in watering sites below standard; land erosion

Surface irrigation is associated with considerable water losses, uneven root zone moistening, increasing irrigation-induced soil erosion, low labor productivity of irrigators, low irrigation system efficiency, etc.

Technology of springs arrangement for stock watering

Low-pressure impulse mist irrigation system

Actions:

At first, the exact location of water outcrop was identified and cleaned from mud.  15 meters below the outcrop, 3 interconnected water tubs were installed (each 1.8 m long, 0.5 m wide and 0.5 deep).  Each subsequent tub is located lower than the preceding one, thus, allowing water flowing down in the cascade manner.

Results:

Financial and economic:

Cattle gaining weight quicker.

Technical:

Improved water supply in the area, including for cattle watering.

Actions:

- Construction of low-pressure impulse mist irrigation system (procurement of polyethylene piping, pumping unit, cassette filter);
- Installation of pumping equipment, settling pond, impulse mist sprinkling nozzles.

Results:

Financial and economic:

rational use of irrigation water; enhanced efficiency of water and land resources use; low cost ($4,164/ha) compared to the basic option ($4,326/ha).

Ecological:

no damage to atmosphere, water and soil and production of ecologically clean agricultural produce.

Technical:

the system operates under low pressure enough to ensure sufficient mist sprinkling irrigation (high-quality artificial rain) creating the necessary microclimate stimulating proper plant growth and development, ensuring even and highly uniform soil moistening; the system is easy to assemble and operate.

Social:

reduced irrigation costs on behalf of water users due to smaller volume of consumed irrigation water; increased profitability of farms due to higher crops productivity.

Lessons learnt:

Collection of water in one place had been practiced since ancient times, but was forgotten over time.  Rehabilitation of traditional practices should be welcomed.

Recommendations:

Similar practices should be scaled-up and continued as they not only benefit the local population, but also allow enhancing water availability for wild animals and expanding hayfield meadows.

Lessons learnt:

Low-pressure impulse mist irrigation system allows improving the overall conditions in greenhouses and/or lemon tree nurseries – rain-like water distribution curbs irrigation-induced soil erosion and unproductive water losses in the course of irrigation.

Recommendations:

It is necessary to widely deploy low-pressure impulse mist sprinkling systems with the aim of irrigation automation and saving irrigation water.

Project title: Low-pressure impulse mist sprinkling system for greenhouses and/or lemon tree nurseries.

Project duration: Apr 2012-Oct 2013.

Project goal and objectives: development and deployment of new low-pressure impulse mist irrigation system for greenhouses and lemon tree nurseries in the context of acute water shortage to ensure even distribution of irrigation water, exclude irrigation-induced soil erosion and unproductive irrigation water losses, thus, leading to water and power saving.

Project beneficiaries: “Ziroatkor” Farm.

Project implementer: Sh. Shotemur Tajik Agrarian University
