| Problem solved through this practice |
Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton |
Low efficiency of furrow irrigation; deficit of irrigation water; poor alfaalfa yields; eroded soil; low income of farmers. |
| Tools used in the practice |
Tubular water outlet flowmeter |
Sprinkling irrigation system for alfaalfa |
| Description of the practice and its results |
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:
- Project design and budgeting, procurement of sprinkling nozzles;
- Installation of sprinkling irrigation system, alfaalfa planting and cultivation, crop care.
Results:
Financial and economic:
increased farmer incomes due to better alfaalfa hay yields; enhanced labor productivity; reduced production costs.
Ecological:
improved ecological and reclamation condition of irrigated land; production of ecologically clean goods; significantly reduced unproductive water losses and soil erosion.
Technical:
increased alfaalfa hay yields (29 t/ha) compared to furrow irrigation (on average 18 t/ha); 40% saving of irrigation water.
Social:
increased wellbeing of local residents due to better agricultural yields; reduced hard manual labor. |
| Lessons learnt and recommendations made |
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:
Deployment of sprinkling irrigation systems allows increasing alfaalfa productivity and water saving as well enhancing soil reclamation condition and structure, watering efficiency, etc.
Recommendations:
It is necessary to widely introduce sprinkling irrigation to enhance the efficiency of water and land resources, reduce manual labor costs and save irrigation water. |
