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

Shortage of irrigation water;
Poor yields;
Low irrigation efficiency;
Eroded soil;
Low income of farmers.

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

Corn drip irrigation system

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:

• Project design and budgeting, procurement of drip irrigation system;
• Installation of drip irrigation system, corn planting and cultivation, crop care;
• Accounting of water and resources.

Results:

Financial and economic:

increased labor productivity and farmer incomes, reduced production costs.

Ecological:

production of ecologically clean goods; prevention of water losses and soil erosion as well as improving soil ecological and reclamation condition.

Technical:

twofold (52%) increase of corn yields compared to furrow irrigation, 51% saving of irrigation water.

Social:

increased wellbeing of local residents due to better agricultural yields; reduced hard manual labor.

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:

Application of drip irrigation ensures higher corn productivity and water saving as well as allows improving soil structure, watering efficiency, etc.

Recommendations:

It is necessary to widely introduce drip irrigation systems to build up the efficiency of water and land resources, reduce manual labor costs and save irrigation water.
