Özet
This study was designated to determine the effect of different applied water by use of different emitter discharges on the wetting patterns of a loam or clay-loam soil under trickle source. Irrigation water was applied when the soil water depletion of 30 and 50% from available water capacity of soil in 0 - 90 depth. The discharge rates of 2 and 4 L h(-1) was selected in irrigation treatments. The parameters affected the wetted soil volume of vertical wetting front advance Z(f), lateral wetting front advance within the soil profile R(s) or at the surface R(f),were researched. The Z(f) and R(s) varied 43 to 58 cm and 54 to 60 cm, respectively. Different emitter discharges had no significant effects on Z(f), R(s) and R(f). Different water applications had significant effect on Z(f) but, had no significant effects on R(s) or R(f). The highest wetted soil volume was obtained as 122681.6 cm(3) irrigation at 50% depletion from the available water capacity of soil from by 4 L h(-1) emitter discharge use. The results showed that higher application rate favors the both vertical and lateral direction of water.
