Opportunities during 22-24, December 2022 at ICAR-CRIDA, Hyderabad
Water lifting techniques: The difference between water lifting methods from bore well and
open source lies in the fact that bore well requires minimum suction head of 40 m whereas
open source pond require only 5 meters. The pump for pond water should have higher
delivery/suction ratio to achieve higher system efficiency.
Pump sizes: Suitable pump sizes are needed to develop by keeping in view that the capacity
of farm pond barely crosses 2000 m 3 , and hence higher capacity pump will be brought
mismatch causing low system efficiency and higher investment.
Standardization of command area under farm pond: The experience suggests that farm pond
of size 30m X 30 m X 3 will be able to provide adequate irrigation to 1 acre of land. Hence
the pumping requirement would not be more than 1.5 hp. These needs to be standardize for
different capacity of pond and respective command for optimal use efficiency.
Selection of Crop: The selection of crop is highly crucial to achieve the water productivity
and profitability.
