Abstract: Hydroponics system is used for the cultivation of horticultural crops in controlled condition with or without the use of any substrate for the good quality production. In this paper hydroponic systems developed by the research workers for cultivation of horticultural crops have been reviewed and summarized. Attempt has been made to review low cost hydroponic systems and can be easily adopted by the urban as well as rural people. There are many techniques which are used in the hydroponics systems like A-frame, U-shaped, Vertical Tower, Horizontal System with the direct circulation of water with nutrient where as in some techniques water is not directly re-circulated but used once like in case of Trough or Grow Bag techniques. On the basis of circulation of water also there are some techniques like flood and drain method, Nutrient Film Technique and Deep Flow Technique which are used in hydroponic systems. Study revealed that system developed and reported are required to be modified further for their adoption for cultivation of horticultural crops.
