Performance of a rehabilitated and turned over flow based minor irrigation project with respect to
irrigation, agriculture and institutional aspects was assessed. The irrigation system was found performing
better. However, inadequacy of irrigation water availability in dry season and spatial inequity of water
distribution, even after rehabilitation and irrigation management transfer were the couple of shortcomings
which have been observed. In order to augment the water resource of the system, the feasibility
of introducing secondary storage reservoir in each outlet command was conceptualized and field tested.
Keeping in view the area required for providing secondary reservoirs, the existing water bodies in the
command of the study system were surveyed. The utility and functioning of the secondary reservoir was
field demonstrated. Utilization of the harvested water in the secondary reservoir for irrigating dry season
crop in addition to the irrigation water from the main reservoir have resulted in increasing the yield of
sunflower, tomato, brinjal and groundnut by 14.29, 14.95, 16.95 and 20%, respectively. Among the cropping
patterns considered, rice–tomato cropping pattern resulted in highest net return (Rs. 29,457 per
ha) followed by rice–brinjal cropping pattern (Rs. 22,430 per ha). Highest benefit–cost ratio of 2.09 was
obtained for rice–sunflower cropping system. The low input-based scientific fish culture in the secondary
storage reservoir has enhanced the fish yield by three fold over traditional practice.
