Problem solved through this practice

Water erosion, discharge, uneven distribution of irrigation water, poor yields

Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton

Tools used in the practice

Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S)

Tubular water outlet flowmeter

Description of the practice and its results

Actions:

Deployment of the Simultaneous Impulse Sprinkling Kit (KSID-10S) allowing extremely uniform and simultaneous dispersion of irrigation water across all sections of arable pasture or hayfield meadow.  Water expenditure at the impulse device makes 0.05-0.3 l/sec and 0.25-2.0 l/sec in the irrigation pipeline, thus, reducing (3-4 times) the costs associated with the pipeline network installation compared to other sprinkling systems (kits). The pipeline network is built of 15-25 mm diameter pipes easy to transport and assemble in mountainous conditions.

Technical characteristics:

Operation modes: automatic and manual

Irrigated area: 10 ha

Water consumption: up to 100 m3/day

Average sprinkling (rain) intensity: 0.002-0.008 mm/min

EFFICIENCY: 99%

MOC: 98%

Watering automation level: 100%

 

Results:

  • Ensured water supply according to crops requirements with the account of changing weather conditions and moisture deposits in active soil layer;
  • Elimination of : 1) water-induced soil erosion, 2) puddling and 3) discharge run-off;
  • No need for water recirculation among irrigation sections.

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:

The advantages of impulse sprinkling irrigation were confirmed by the research efforts on other test sites of KAZNIIVKh in Jambyl Region that allowed increasing biological productivity of Golden Delicious apple variety by 10.1-36.8%, and commercial productivity – by 16.6-49.4% compared to conventional sprinkling irrigation systems.

Recommendations:

It is necessary to continue application of similar practices in foothill areas in Central Asia subject to power supply shortages.

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.
