| 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. |
