Abstract:

Being one of the key factor in designing and managing the drip irrigation system, moisture profile is essential for optimization of spacing of emitters as well as laterals. The experiments include surface drip irrigation system having three discharges viz., 2 lph, 4.4 lph and 6 lph conducted in farms of pump and Wells laboratory shed of College of Agricultural Engineering, Samastipur, Bihar. The experiment was managed in a metallic cylindrical tank having suitable dimensions which was full of soil. The experiments were conducted by drip emitters of different discharge rates and the tenacity of moisture in soil for different discharge was measures with tensiometer. Contour maps were plotted from the data recorded during the experiment for different discharge rates of 2 lph, 4.4 lph and 6 lph using the Surfer – 7 software. The experiment concluded that the horizontal spread of water increases with increase in discharge of emitter. The horizontal spread was observed to be about 23.3% and 43.3% more when the emitter discharge rate increased from 2 lph to 4.4 lph and 6.0 lph respectively. The vertical spread of water decreases with increase in emitter discharge rate. The vertical spread was observed to be about 18.0% and 32.0% less when discharge was increased from 2 lph to 4.4 lph and 6.0 lph respectively.


Keywords: Drip irrigation system, Moisture profile, Tensiometer, Horizontal spreading and Vertical spreading.
