CIRCULAR-SHAPED EMITTER AS ALTERNATIVE TO INCREASE IRRIGATION EFFICIENCY

Abstract

As respond to demand on reducing water for agricultural sector as the water usage competition is increasing between various sectors, water efficient irrigation techniques were offer in order to keep the water status at the desirable level at a production land, while avoiding loss of water and within a certain amount of water available. Automation system was applied to micro irrigation system using circular shaped irrigation emitter. The irrigation system is proven to work and keep the soil moisture at the desired condition which is field capacity, between pF 2.54 and 4.2. As the soil moisture was kept within the range percolation can be suppressed to its minimum or even halt. The system can be improved and used for dry land agriculture.
