Practice usage period

Start date: 01.01.2014

End date: 31.12.2016

Problem solved through this practice

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

Tools used in the practice

Technique and technology of mist sprinkling irrigation

Description of the practice and its results

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 and recommendations made

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.

Information sources

The PhD thesis “Efficiency of mist (sprinkler) irrigation 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.
