Design of fuzzy controller based on penman-monteith equation for drip irrigation

Abstract

The agriculture sector plays vital role in overall socio-economic status of India. The involvement of Indian population in agriculture and associated activities is 54.6% (census 2011). The net cropped area is 43% of entire geographical region of India and area under irrigation is 68 million hectares. However, availability of water is an important for agriculture. The supply of water to agriculture field is known as irrigation, in traditional irrigation method there is wastage of water. The evapotranspiration (ET) is combined technique, in this wetness of soil is lost in the form of evaporation in atmosphere and plants absorbing water from soil is transferred to atmosphere. Evapotranspiration depends on uncertain parameters like radiation of solar, temperature of air, speed of wind and humidity. Thus, in this research work a smart fuzzy control water irrigation system is designed to tackle uncertain situations maintaining proper water level as per requirements of crops.
