Poor technical condition, operation and maintenance of the irrigation system

Irrigation-associated soil erosion, low efficiency of applied watering techniques, poor phytosanitary condition of land used for vegetable growing

MASSCOTE methodology

Technique and technology of mist sprinkling irrigation

Actions:

Mapping of the system and services depending on canals’ purpose.

Results:

Financial and economic:

economically effective, fair and sustainable water resource management.

Ecological:

integrated protection of key environmental elements, including prevention of raising ground water level and secondary soil salination as well as irrigation-induced soil erosion, etc.

Technical:

improved technical characteristics of municipal water supply to different stakeholders.

Social:

enhanced welfare of farm employees due to increased income.

Actions:

A sprinkler (artificial rain irrigation) system installed consisting of 50 mm diameter polyethylene pipes assembled from 10-12 meter segments (5022 SD sprinkler; 3.5 bar pressure; 3.5 mm nozzles; water consumption of 0.87 m3/hour; water distribution area per 1 sprinkler – 12 m).

Results:

Financial and economic:
Compared to ridge-and-furrow watering method, sprinkler irrigation led to a yield increase for the following crops:
• carrots – 15.64%,
• cabbage – 12.78%,
• sweet pepper – 14.19%.

Technical:
• up to 20% reduced irrigation water consumption,
• prevention of irrigation-induced soil erosion,
• improved phytosanitary condition of vegetable fields.

Lessons learnt:

Express assessment based on MASSCOTE methodology allows to improve the planning of upgrading efforts to ensure better servicing of diversified water uses requiring higher supply flexibility and cost reduction.

Recommendations:

It is necessary to widely deploy the MASSCOTE methodology of express assessment of the condition of irrigation systems and enhancing their operation.

Lessons learnt:
The practice demonstrated the possibility of effec-tive water use, reducing labor costs, and increasing yields of several horticultural crops simultaneously.

Recommendations:
Widespread introduction of sprinkler-based mist irrigation systems along with drip irrigation and other advanced water-efficient technologies is necessary. In order to ensure that, water users should have strong financial incentives to facilitate water saving.

Project title: Using MASSCOTE methodology for express assessment of the condition of Vakhdat municipal irrigation system.

Project duration: 2016.

Project goal and objectives: designing the irrigation system upgrading and management plan based on MASSCOTE methodology of process diagnostics and assessment of irrigation system performance.

Project beneficiaries: land and water users.

Project implementer: UN FAO.

The PhD thesis “Efficiency of mist (sprinkler) irriga-tion technology for vegetable crops in southeastern Kazakhstan” describing a vegetable (cabbage, carrots, sweet pepper) cultivation technology based on fine sprinkling irrigation developed for the first time for soil and climatic conditions of foothill zone in southeastern Kazakhstan, including an optimal mode of vegetables irrigation via fine overhead sprinkler-based irrigation was developed, as well as analyzing the effects of sprinkler irrigation on biomass formation and crops capacity.
