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. |

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. |
