|Title||Using low-pressure impulse mist irrigation system for watering agricultural crops|
|Category of tools||Sprinkling system|
|Field of application||
Use of water resources
|Usability of practice for adaptation to climate change||High|
|Implemented by||Sh. Shotemur Tajik Agrarian University
Province: Districts of Republican Subordination
|Practice usage period||
Start date: 01.04.2012
End date: 31.10.2013
|Problem solved through this practice||
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.
|Tools used in the practice||
Low-pressure impulse mist irrigation system
|Description of the practice and its results||
- Construction of low-pressure impulse mist irrigation system (procurement of polyethylene piping, pumping unit, cassette filter);
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).
no damage to atmosphere, water and soil and production of ecologically clean agricultural produce.
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.
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 and recommendations made||
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.
It is necessary to widely deploy low-pressure impulse mist sprinkling systems with the aim of irrigation automation and saving irrigation water.

|Brief information on the project||
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
