Objectives:

The foremost objective of AED is to increase the income of the farming community. The second objective is Water Savings and the third one is labour savings. These three objectives are achieved by adopting the following methodologies.

• By introduction of Micro Irrigation System, i.e. installing Drip & Sprinkler Irrigation systems.
  
  
  • Water is applied to the root zone of the crop, at required quantity, at required interval. By this, total vigor of the crop improves and hence the Yield increases.
  • Weed growth is limited around the plant and hence expenditure on Weeding is reduced.
  • Cost of Labour for irrigation is reduced.
  
  
• By promoting innovative, novel implements, the drudgery of farm labour and the requirement of labour are reduced and hence total cost of cultivation is reduced.


• By construction of Farm Ponds in the farmer’s field to harvest the excess run off water input will be augmented / supplemented through Open / Tube wells.


• By installing buried PVC pipe line system from the sluice point to the ayacut
  
  
  • The water conveyance efficiency improves
  
  
  • Hydrants provided at the field will be interlinked to Micro Irrigation systems to improve application efficiency
