Present study recommends an option to overcome the limited water availability in
surface irrigation system through provision of secondary reservoirs in the command.
The harvested water can be utilized for irrigation in the dry season, short duration
fish culture, etc. Approximately 10% of the command area is required for the
secondary reservoir with assumption of 50% capacity of the main reservoir will be
available for irrigating dry season crops. The demonstration of use of water from
the secondary reservoir in addition to the water from main reservoir has resulted
in substantial crop and fish yield. The gross and net returns from various cropping
patterns considered using irrigation water from main reservoir (MR) and from main
and secondary reservoir (MR+SR). Among the cropping patterns considered, ricetomato
cropping pattern resulted in highest net return of INR 29,457/ha followed
by rice-brinjal cropping pattern (INR 22,430/ha) with benefit cost ratio of 2.07 and
1.79, respectively. Highest benefit-cost ratio of 2.09 was obtained for rice-sunflower
cropping system due to relatively lower cost of cultivation of sunflower. The highest
incremental value of net returns of 3710 `/ha was obtained with rice-tomato cropping
system. The low input-based scientific fish culture in the secondary reservoir has
enhanced the fish yield by three fold over traditional practice increasing the gross
return from the system. The economic analysis also revealed that the intervention is
economically viable
