A field experiment was conducted to study the horizontal and vertical movement of moisture front under point and line source of trickle irrigation system by operating system up to three hours. Emitter of 2, 4, 8 lph discharge were used for studying the moisture movement under point source and 4, 5, 8 and 10 l/m/hr discharging emitter for the wetting pattern under line source. The effect of antecedent moisture content on Radial as well as Vertical movement was also considered in this field Experiment. The relationship between Radial movement and Vertical movement with respect to irrigation time, both can be described by a power function. Result revealed that vertical movement was found more in line source as compare to point source while more horizontal movement was observed in point source than line source irrigation. | Soil wetting pattern under point and line source of trickle irrigation
