NOVEL TECHNIQUE FOR PLANT IRRIGATION USING DYNAMIC HEAD OF EVAPORATION

Abstract

Our agriculture system now facing of severe productivity decline due to the increased cost of production. One of the major problem, this sector facing is non availability of enough water and power. The cost per unit power is increasing day by day so we introduce a novel technique to irrigate the plant with conserving both power and water. The traditional irrigation system supply fixed quantity of water to the field without considering the crop water requirement. The crop water requirement varies according to the weather and other environmental conditions. A dynamic head water supply system is essential to meet the crop water requirement and there by optimizing the productivity. Existing technology uses sensor based on/off controlled irrigation system with area varying technique. In this paper a novel technique of irrigation system is presented. Here the crop water demand is assessed by pan evaporation water level method. Which is a water head demand is communicated to supply water head system. The input parameters measured from pan evaporation are modeled and estimated the time for maintaining water required for irrigation. These results are then simulated. Data collected from CPCRI Kasaragod for the year 2012 of pan evaporation and field data is compared.
