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.

A two-stage rainwater conservation technique was intervened in the farmers field of rainfed shallow low land, in which, part of the rainwater is conserved in rice field up to the weir crest level and the remaining in a refuge for rearing of fish (Catla catla, Labeo rohita, Cirrhinus mrigala and Cyprinus carpio). The conserved rainwater in the refuge is also used for giving supplemental irrigation to rice crop during rainy season and growing a light duty crop in winter season. On-farm experiment was conducted in the farmer’s field for three consecutive years to study the scope and feasibility of this technique in enhancing productivity and cropping intensity. Three different weir heights (15, 20 and 25 cm) were considered as treatments with two replications each. Refuge occupying areas of 5–8 % of the rice field with a depth of 1.75 m were constructed at the downstream side of each plot. As a result of this intervention, the mono-cropped area could be gradually brought under double cropping. The rice yield increased from 1.8 to 5.3 t/ha. Fish yield of as high as 1,693 kg/ha was obtained for a fish rearing period of about 6 months. The net water productivity increased from 3.76 to 7.38 Rs./m3. The highest net return of Rs. 63,572 was recorded in 20 cm weir height plots with a benefit cost ratio of 2.60. The system generated employment opportunity, increased income for farmers and provided nutritional security.

This study was carried out in farmers’ fields to quantify the total water and consumptive water use in grow-out culture of Penaeus monodon under recommended package of practice with two different water management protocols: T1, with no water exchange and T2, with regulated water exchange. Treatment-wise estimated total water use, was 2.09 and 2.43 ha-m 122 day 1, while the computed consumptive water use index (m3 kg 1 biomass) was 5.35 and 6.02 in T1 and T2 respectively. Lower rates of water exchange (T2) showed significantly improved (P < 0.05) crop performance in terms of performance index (19.75 0.75), production-size index (74.1 3.4), survival rate (80.13 1.7%) and productivity (2.44 0.08 t) over the zero water exchange. The shrimp pond water quality suitability index (WQSI) infers that regulated water exchange (T2) improved the overall suitability of water quality for shrimp culture. WQSI up to 90 days of culture ranged between 7.5–9.0 in T2, needs little management while in the last month of rearing, it was good with moderate management requirements. Treatment-wise sediment load ranged between 50.4–56.3 m3 t1 shrimp biomass. High intensity of water exchange and low apparent feed conversion ratio influenced in lowering the sedimentation rate. Regulated water exchange protocol (T2) performed well (higher net total water productivity and net consumptive water productivity) against no water exchange (T1). A higher OV:CC ratio (ratio of the output value to the cost of cultivation) indicated that T2 had a distinct edge over the T1 protocol.

We quantify the total water use (TWU) and consumptive water use index (CWUI) in grow-out culture of Penaeus monodon at different water and feeding management protocols using the water balance equation. Under two different water management protocols, treatment-wise TWU, was 2.09 and 2.43 ha-m 122 d-1 in T1 (no water exchange) and T2 (water exchange on ‘requirement’ basis depending on water quality), respectively. The computed CWUI (m3 kg-1 biomass), was 5.35 and 6.02 in T1 and T2, respectively. Lower rates of water exchange (T2) showed significantly improved water quality, crop performance and productivity over the zero water exchange protocol. Similarly, under three different feed management protocols, treatment-wise estimated TWU was 2.52, 2.44 and 2.41 ha-m 119d-1, while the computed CWUI was 7.28, 6.88 and 6.34 in T1 (Regular feeding, 4-times a day), T2 (2-weeks feeding followed by 1-week no feed) and T3 (4-weeks feeding followed by 1-week no feed), respectively. Higher the feed input, higher was the TWU and CWUI. It was also recorded that longer the refeeding period, higher was the growth performance and yield as in the case of T3. This feeding practice also helped in lowering the feed input (7.5% in T2 and 5.5% in T3), thus minimizes the input cost and improve production efficiency.

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, rice-tomato 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.

This study was designed to quantify the total water requirement and consumptive water use in carpprawn polyculture system under different water management protocols, using water balance model. Under different water management protocols, treatment-wise estimated total water use, TWU (9104, m3) was 3.7, 4.6 and 3.9, while the computed consumptive water use index, CWUI (m3 kg 1 biomass) was 6.62, 9.31 and 7.08, in T1 (no water exchange), T2 (periodic water exchange) and T3 (regulated water exchange) respectively. Significantly higher yield (P < 0.05) in both T2 and T3 over T1, was probably due to water exchange that improved the rearing environment. Although intensity of water exchange was more in T2, significant variation (P < 0.05) in overall growth and yield was not recorded between T2 and T3. Treatmentwise sediment load ranged between 54.6 and 71.3 m3 t 1 biomasses. Higher sediment load was recorded at lower intensity of water exchange as well as with higher apparent feed conversion ratio. Higher net total water productivity, net consumptive water productivity and OV-CC ratio in T3 infers that regulated water exchange has a distinct edge over the no water exchange protocol. Restricted water use instead of regular/excess water exchange not only improves the production performance and water productivity, but also helps in lessening the operational pumping cost.

Agricultural technology introductions were carried out and their impact was studied in two clusters of villages in the Dhenkanal Sadar and Odapada blocks of Dhenkanal District in Odisha in the eastern Indian plateau region. Ten water-harvesting structures (WHSs) were constructed in two clusters of villages in the farmers’ fields on a participatory basis. Harvested water in WHSs was used for multiple purposes, viz. agriculture, fish culture, on-dyke horticulture, vegetable cultivation, poultry, dairy and mushroom cultivation; integrated farming system (IFS) models were developed. Adequate training was also given to the farmers. The net income from the integrated farming systems varied widely between Rs. 16 100 and 251 000 ha 1 . Poultry farming in the uplands and intensive cultivation around the embankments of the ponds were found to be effective in increasing the net return from the IFS models. Impact analysis of the water resources development and technology introductions at the study sites was carried out by analysing the comparative position of physical, social, financial, human and natural assets of the farmers before and after adoption of the introductions. The overall standard of living of the study farmers increased from 13.5 to 17.1 on a scale of 5 to 25, respectively.
