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

Increasing secondary land salination, deterioration of col-lector and drainage system (CDS)

Sprinkling irrigation system for alfaalfa

A set of measures to enhance land reclamation condition (collector cleaning using special equipment, reconstruction of hydraulic engineering installations, etc.)

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:
The capital repair of inter-farm West Karmakshi Collector (WKC) is necessitated by the fact that in its current condition the Collector didn't provide for timely drainage of drainages and discharge water from cropland in the Left-Bank Massif.

Results:

Financial and economic:
Increased crop productivity, mainly rice and forage crops

Technical:
Enhanced reclamation condition of land in the Left-Bank Massif

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:
Allocation of resources for cleaning CDS proved more efficient than other target actions

Recommendations:
Regular and timely execution of running and capital collector cleaning is necessary to ensure its proper operation
