Irrigation is the artificial application of water to the land. Irrigation is used for growing of agricultural crops, maintenance of landscapes, and re-vegetation of soils in dry areas during periods of inadequate rainfall. There is an urgent need to develop improved irrigation strategies for sustainable use of water resources. Drip irrigation is also known as trickle irrigation or micro irrigation or localized irrigation. It allows water slowly to the roots of plants, through a valves, pipes or emitter. Drip Irrigation prevents soil erosion, saves water and fertilizer. Farmers can produce higher yields while saving on water as well as fertilizers. Water and nutrients are delivered across the field in pipes called ‘drippers’. Each dripper emits drops containing water and fertilizers, resulting in the uniform application of water and nutrients direct to each plant's root zone, across an entire field. Wireless sensor network system consists of large numbers of wireless sensor nodes which are distributed across agricultural environment in order to make sure high precision and reliability of data acquisition. A sensor network is an emerging field with increasing applications day by day. Wireless monitoring of field not only allows user to reduce the human power, but it also allows user to see accurate changes in it. It is cheaper in cost and consumes less power.
