Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton

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

Tubular water outlet flowmeter

Sprinkling irrigation system for alfaalfa

Actions:

- Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles);
- Installation of tubular water outlet flowmeter along temporary sprinklers. 

Results:

Financial and economic:

saving of irrigation water; low cost of irrigation system automation (total kit cost: $500/ha) with the service life of 5 years. 

Technical:

simple design allowing a more even distribution of irrigation water stream among furrows, thus, ensuring the prescribed water supply mode.

Social:

improved working conditions of irrigators; lower labor needs/costs; enhanced mutual trust among farmers and water users.

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:

Installation and deployment of tubular water outlet flowmeter allows to improve the uniformity of irrigation stream’s distribution among furrows and conduct irrigation water accounting.

Recommendations:

It is necessary to widely use the small-scale irrigation automation means like the tubular water outlet flowmeters which have simple design, are convenient to operate, are low-cost and mobile and ensure supply of the prescribed amount of irrigation water.

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.
