• The factors affecting the duty have been explained in previous article of this chapter.
  • If these factors are somehow made less effective the duty of water can be considerably increased.
  • Methods of improving duty have been enumerated as follows:
  1. By selecting such method of applying water.
  2. which would cause least wastage by way of seepage, percolation, and evaporation.
  3. Land should be properly ploughed and levelled so that a thin sheet of water may evenly be spread over it.
  4. The fields should be frequently ploughed.
  5. This measure reduces loss of moisture specially.
  6. when ground water is within capillary reach of the ground surface.
  7. Fields should be divided into small kiaries.
  8. Smaller the size of kiaries more will be the duty of water.
  9. Area to be irrigated should be located as near the canal as possible.
  10. This reduces coveyance losses and duty is increased.

Methods of improving duty

  1. In other words idle length of the canal should be minimum.
  2. Volumetric method of assessment should be adopted.
  3. Only that much land should be given to the farmers as they can carefully look after.
  4. Farmers should be given training for judicious use of water.
  5. All the canals, water courses should be lined.
  6. The alignment of canal either in sandy soil or in fissured rocks should be avoided.
  7. Severe punishments should be awarded for those who get irrigation water by unlawful means.
  8. Deliberate canal cuts should be prevented by resorting to effective patrolling of canals by the staff.
  9. Water tax should be increased. This measure will force farmers to use water more economically.
  10. Research stations should be established in adequate number and research in regard to moisture conservation, and economical use of water should be continuously carried out.
