Tools used in the practice

Corn drip irrigation system
Description of the practice and its results

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:

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.
