Low efficiency of furrow irrigation; deficit of irrigation water; poor alfaalfa yields; eroded soil; low income of farmers.

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

Sprinkling irrigation system for alfaalfa

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

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.

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.

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.

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.
