Dear Dr Balbir Singh, We are ...

Dear Dr Balbir Singh, We are in to the business of micro irrigation. With the crops such as cereals, Pulses and Oil seeds ( as mentioned in your mail low water consuming crops), the daily water requirement in case of  micro irrigation can be assumed at 3-4 mm per day ( which is equivalent to 30- 40 m3/ha/day). Total water required in a season thus would be 40 x 120 = 4800 m3/ha.  In this, evaporation losses can be added and you can arrive at the volume of the pond. You may have to leave some free board. I think it would be better to keep the depth more than 1 m, say 3-4 m would be ok. Do you agree with me ? Thanks and regards Somnath Jadhav,  Jain Irrigation Systems Ltd
