Aquaponics is a combination of hydroponics (growing crops without soil) and traditional aquaculture. Nutrient from the fish waste feed the plants, and the plants filter the water to keep the fish healthy. An experiment was conducted to study and analyze the comparison between aquaponics, hydroponics for the cultivation of lettuce. GIFT was used as a source of nutrient as well as income generation in aquaponics where as in hydroponics nutrient solution was artificially prepared using various chemical combinations. The technique employed was deep water culture. Both the systems were designed and maintained properly. Fish pond was designed as 16 m3 with a bio-filter of 3m3 capacity filled with sand and pebbles as filter media as a source of nutrient for aquaponics. 500L tank filled with nutrient solution was used as a source of nutrients for hydroponics. Volume of media was 0.57m3. In order to improve the total returns of farmers the complete system was operated with solar energy and 120W solar panel connected with DC pumps were used for water circulation. In the process of performance evaluation, mean Plant height, Plant width, No. of leaves, Root length, Root spread, Leaf area index, Chlorophyll content, fish weight, yield per plant, yield per pipe, yield per system and yield per hectare was found as 6.69 and 5.15 (cm), 8.85 and 4.36(cm), 3.64 and 3.7(no.s), 4.27 and 3.59(cm), 1.74 and 0.87(cm) 0.80 and 0.42, 11.92 and 9.3(µmol/m2), 89.5(g), 62.88(g), 1194.64 (g), 2.26(kg) and 30.25(kg) for aquaponics and hydroponics respectively.
