Improvement of water use efficiency and per capita water storage in India
 
Field Evaluation Report:
This year during July to December, there were several stress periods of rainfall. From July 15th to Aug 13th there was no rainfall & the fields were dry. Because of stored water in Rubber Dam, irrigation could be given through diversion channel on left side of the dam to around 40 ha area for more than 100 farmers. But crop cutting was made by sampling for 19 farmers. During flowering stage of the paddy i.e. the critical stage of the crop in November there was scanty rainfall and the stored water of the dam has saved the crop. During 2nd week of December, there was unusual heavy rain & entire harvested water was saved in Dam. This became useful for Rabi pulses amounting to 60 ha. The average yield of paddy (kharif) during 2008-09 was 2.5 to 3.1 t/ha where as during 2009-10 kharif it was 4.2 to 4.9 t/ha.
 
Impact of Rubber Dams:
  • Installed Rubber Dams has given a very good impact on crop yield in surrounding areas, farmers of Bhubaneshwar and Irrigation Dept., Govt. of Orissa. Many agencies are ready to scale up the technology
  • Water stored in dams was supplied for productivity of different crops such as paddy/rice,   cowpea, cucumber, sunflower, ridge gourd, pumpkin etc.
  • There was increase in productivity of crops (60%) in surrounding areas after installation of dams than, before installation of dams
  • The overall economics of surrounding areas was increased, after installation of Rubber Dams
