dc.description.abstract | 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. | en_US |
