Sprinkling irrigation of alfaalfa in the conditions of Central Tajikistan

 

Title Sprinkling irrigation of alfaalfa in the conditions of Central Tajikistan
Category of tools Sprinkling system
Field of application
  • Use of water resources
  • Use of land resources
Usability of practice for adaptation to climate change High
Implemented by GU “TajikNIIGiM” (“Research and Development Insti-tute of Hydraulic Engineering and Reclamation of Tajikistan” State Enterprise)
Used by

Country: Tajikistan

Province: Districts of Republican Subordination

District: Rudaki

Settlement: Khosilot Farm
Local specifics
  • Ground water occurrence below 5 meters;
  • Typical gray soil, surface slope – 0.04.
Practice usage period

Start date: 01.01.2013

End date: 31.12.2015
Problem solved through this practice

Low efficiency of furrow irrigation; deficit of irrigation water; poor alfaalfa yields; eroded soil; low income of farmers.
Tools used in the practice

Sprinkling irrigation system for alfaalfa
Description of the practice and its results

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.
Lessons learnt and recommendations made

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.
