| 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. |
Усиливаются процессы вторичного засоления земель, отмечено ухудшение работ коллекторно-дренажных систем (КДС). |
| Tools used in the practice |
Low-pressure impulse mist irrigation system |
Комплекс мер по улучшению мелиоративного состояния земель (механизированная очистка коллектора, реконструкция гидротехнических сооружений и др.). |
| Description of the practice and its results |
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. |
Мероприятия:
Необходимость капитального ремонта межхозяйственного Западно-Кармакшинского коллектора (ЗКК) вызвана тем, что существующее его состояние не обеспечивало своевременного водоотвода дренажно-сбросных вод с посевных площадей с Левобережного массива.
Результаты:
Финансово-экономические:
Увеличилась урожайность сельхозкультур – в основном риса и кормовых культур
Технические:
Улучшилось мелиоративное состояние Левобережного массива |
| Lessons learnt and recommendations made |
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. |
Уроки:
Вклад средств в очистку КДС намного эффективней других мероприятий.
Рекомендации:
Нужно регулярно и своевременно проводить текущие и капитальные механические очистки коллекторов |

| 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 |
