“…Evaporation losses can be minimized by 50% when the soil is kept at saturation under leveled field conditions. Higher the transpiration higher the yield (a normal crop of 4.5t/ha (tones/hectare) with an irrigation period of 100 days consumes 6 mm/day by transpiration [6]. 1.4 mm/day the yield decreases to 1t/ha when it increases 10.5mm the yield of crop will be increased upto 7.5 t/ha).…”

Abstract:The farmers working in the farm lands are solely dependent on the rains and bore wells for irrigation. Even if the farmland has a water-pump, manual intervention by the farmers is required to turn the pump ON/OFF whenever needed. Therefore using an Android application which helps the farmer to ON/OFF the motor without his physical presence in the field. This paper has real time sensing and control of an irrigation system. When the condition of water in the agricultural farm is abnormal then the system automatically switches OFF. Based on the soil moisture, through relay the pumping motor will be automatically switch on or off which saves the water and on the other hand the plant can get most appropriate water level which increases the productivity of the crop. Using GSM (Global System for Mobile communication) technology which is used to inform the user about the exact condition of the field. This information is passed onto the user request in the form of SMS (Short Message Service). The proposed system provides uniform and required water level for the agricultural farm and it avoids water wastage.

“…Stand alone controllers measure climatic variables (temperature and solar radiation) on site and then determine a cumulative daily ET value. Signal based controllers receive ET data from a wireless connection while historical ET controllers rely on historical ET information for the area (Davis and Dukes, 2010). Three ET controllers evaluated in southwest Florida by Davis et al (2009) reported an averaged water savings of 43% over time-based irrigation without a rain sensor.…”

“…Three ET controllers evaluated in southwest Florida by Davis et al (2009) reported an averaged water savings of 43% over time-based irrigation without a rain sensor. Davis and Dukes (2010) reported that properly programmed ET controllers are more effective than manual irrigation scheduling because they can adjust to real-time weather and minimize over-watering.…”

“…Ideally they replace the water lost due to ET. There are several different types of ET controllers including standalone controllers, signal based controllers, and historical based controllers (Davis and Dukes, 2010). Stand alone controllers measure climatic variables (temperature and solar radiation) on site and then determine a cumulative daily ET value.…”

“…Systems based on ET have been developed that allow water savings of up to 42% on timebased irrigation schedule [3]. An electromagnetic sensor to measure soil moisture was the basis for developing an irrigation system at a savings of 53% of water compared with irrigation by sprinklers in an area of 1000m 2 of pasture [4]. A reduction in water use under scheduled systems also have been achieved, using soil sensor and an evaporimeter, which allowed for the adjustment of irrigation to the daily fluctuations in weather or volumetric substrate moisture content [5].…”

Farming is a major occupation for many people in countries like India, and it is the life line for entire population of the world. Water is the backbone of the farming industry. As per India is censured, lots of water gets wasted due to many reasons. Smart Irrigation System serves a way to minimize this wastage of water in agricultural fields. The system incorporates the features of IoT. The supply of water in the fields is controlled by sensing the requirement of water in the fields using various sensors and switching the pump on and off automatically according to the requirement.
