Abstract
As we know that earth surface is covered with 75% of water and out of that only 2.5% of water is fresh, from that we use 70% of fresh water for irrigation. From research we came to know that maximum amount of water is getting loss in agricultural field, water withdrawal rate in 2050 is 50% in developing countries like India. To solve the problem of water scarcity, we need proper water management and water efficient irrigation system. Clay pipe irrigation system is the one of the most water efficient, eco-friendly and cheapest method. In this system we use clay pipes which are buried into the sub surface of the soil and by the capillary action water sweeps out from the unglazed wall of the clay pipes due to which soil get moisturize. By this method only optimum amount of water is provided to the crops. As in this system there is no water logging on the soil surface, hence we can also solve the weed management issue and proper salt distribution in the soil. This method is so easy to manage as no high-tech work is required and it is eco-friendly also because no toxic and residual waste is used in this system. Initial cost for this system is 40,000 rupee per acre (aprox) and it is multi seasonal (this system can be use for more than 10 seasons). This is suitable for those regions where the rainfall is less than 500 mm per year. Clay pipes will have proper composition of clay and ash so that it has proper water permeability and maintained porosity. All the fibrous root crops like fibrous root vegetables can be practice by this method and they will give good yield and quality. Water saving rate from this method is 50-70% in vegetable crops. It is more viable in intensive agriculture.
