Problem solved through this practice

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

Shortage of irrigation water;
Poor yields;
Low irrigation efficiency;
Eroded soil;
Low income of farmers.

Tools used in the practice

Tubular water outlet flowmeter

Corn drip irrigation system

Description of the practice and its results

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 drip irrigation system;
  • Installation of drip irrigation system, corn planting and cultivation, crop care;
  • Accounting of water and resources.

Results:

Financial and economic:

increased labor productivity and farmer incomes, reduced production costs.

Ecological:

production of ecologically clean goods; prevention of water losses and soil erosion as well as improving soil ecological and reclamation condition.

Technical:

twofold (52%) increase of corn yields compared to furrow irrigation, 51% 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:

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:

Application of drip irrigation ensures higher corn productivity and water saving as well as allows improving soil structure, watering efficiency, etc.

Recommendations:

It is necessary to widely introduce drip irrigation systems to build up the efficiency of water and land resources, reduce manual labor costs and save irrigation water.
