Проблема, которая решается применением практики |
Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton |
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. |
Примененные в практике инструменты |
Tubular water outlet flowmeter |
Low-pressure impulse mist irrigation system |
Описание практики и ее результаты |
Actions:
- Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles); - Installation of tubular water outlet flowmeter along temporary sprinklers.
Results:
Financial and economic:
saving of irrigation water; low cost of irrigation system automation (total kit cost: $500/ha) with the service life of 5 years.
Technical:
simple design allowing a more even distribution of irrigation water stream among furrows, thus, ensuring the prescribed water supply mode.
Social:
improved working conditions of irrigators; lower labor needs/costs; enhanced mutual trust among farmers and water users. |
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. |
Какие уроки и рекомендации можно извлечь из практики |
Lessons learnt:
Installation and deployment of tubular water outlet flowmeter allows to improve the uniformity of irrigation stream’s distribution among furrows and conduct irrigation water accounting.
Recommendations:
It is necessary to widely use the small-scale irrigation automation means like the tubular water outlet flowmeters which have simple design, are convenient to operate, are low-cost and mobile and ensure supply of the prescribed amount of irrigation water. |
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 duration: Apr 2010-Oct 2011.
Project goal and objectives: development and deployment of a crop watering technology for dekhan farms of the Republic of Tajikistan allowing to significantly increase the efficiency of water use.
Project beneficiaries: members of “Istikol” WUA (Water User Association).
Project implementer: Institute of Water Issues, Hydropower and Ecology of the Academy of Sciences of the RTj |
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 |
