Water deficit, poor irrigation technology

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

Wheat irrigation technology based on Valley Sprinkling Machine

Technique and technology of mist sprinkling irrigation

The sprinkler is produced by the US Valley Company established in 1946 and considered one of the world leading designers and manufacturers of water-efficient irrigation and water supply equipment for agriculture, industry and municipal purposes.

Actions:

The first case of using such a large-scale sprinkling irrigation machine in Turkmenistan’s agriculture.  The machine’s operation does not require careful field planning.  The machine’s scale (extension up to 1,000 meters) allows it to irrigate up to 300 hectares of land. Frontal installation with reinforced irrigating shoulder bars moves back and forth across the field and ensures uniform watering of the whole acreage.

The government provides a 10-year soft loan with 1% annual interest rate to procure such units.

Results:

Application of water sprinklers allows the two-fold saving of water resources and higher yields. Due to its overall high quality and advantages, Turkmenistan’s agricultural producers became interested in the technology – multiple orders were placed to procure and install such smart sprinkling machines.

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:

Advantage of sprinkling machines:  

• fitting with fertilizer administration units;
• fitting with units for spraying disease, pest and weed control agents;
• capable to replace water spraying tractors;
• no need for seasonal field works;
• lower agricultural production costs.

Recommendations:

After successful testing, other candidates for the installation of irrigation machines declared their corresponding desire (Ashyk Aydyn Daikhan Association of Rukhubelent Etrap of Dashoguz Velayat that already installed a different type of sprinkling system covering 174 hectares).  Since Akhal Region is close to the capital, it is necessary to introduce more water-efficient technologies focusing on garden and cucurbit crops to address food supply issues.

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.

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.
