Aquaponics is the eco-friendly system which is used for the production of food by utilizing certain concepts such as aquaculture and hydroponic. These methods ultimately help us to cultivate fish and crops without the vicinity of soil . The growth performance of a fish along with certain leafy vegeta-bles will be tested and the result will be estimated during the recirculation of the system with respect to the temperature and the effective use of the fish excretion. Arduino usually acts as the brain of the system and that being used in aquaponic helps us to receive the information from the sensors and reciprocate as instructions with respect to feedback. Later, actions will be initiated based on the systems actuator. Aq-uaponics is an inexpensive symbiotic cycle between the living organism and the crop. In this system Fish excretion (ammonia) is incorporated into the plant bed which in turn acts as the biofilter and grasps the nitrate that is crucial for vegetation. Then the fresh water is returned to restart the cycle. The Fish is fed with pellets that contains 30% of the crude proteins that enhances almost all the nutrients that are re-quired for efficient plant growth.

The article analyzes the state of water use in agriculture in Uzbekistan and examines the reasons for their waste. It analyzes the current state of water use on irrigated agricultural lands in the world and in the country, as well as programs of measures to address issues and problems of efficient use, and makes relevant proposals for their more efficient use. It also analyzes the views of experts on the recognition of water efficiency indicators in relation to key indicators, based on the fact that the same indicators cannot be applied uniformly as a result of global climate change, given the characteristics of specific and relative indicators of water use efficiency. In Namangan region, econometric models of changes in the volume of production depending on the conditions of water use in arable lands were developed and analyzed. As an indicator of water efficiency, crop yields were studied and suggestions and recommendations for water efficiency were presented.
