Abstract

Drip irrigation, because of its high efficiency on SLOPING LANDS is a suitable irrigation system in most countries around the world. WETTING PATTERN recognition formed by a source point which is called “wetting pattern is very important in drip irrigation. The WETTING PATTERN depends on the soil texture and structure, the volume of applied water, the discharge of emitters and the land slope. In this research the effects of slope and irrigation time on WETTING PATTERN were assessed for constant discharge equal to 4 liters per hour. Experiments were performed on lands with 0, 5, 15 and 25 percent slopes with silt –loam soil texture in three irrigation times of 2, 4 and 6 hours, in 3 replications. So based on the results of experiments and the measurements, table 6 and 7 were presented for designing of drip irrigation system in silty-loam soils. According to results of table 6 on SLOPING LANDS in silty-loam soils, applying 6 hours of irrigation time and locating the emitters 56 to 65 centimeters apart from each other, from the point of view of wetted area overlapping gives an appropriate result. Table 7 results show that using the double row arrangement for laterals on SLOPING LANDS give high wetting area. If drip irrigation system is used for cultivating on SLOPING LANDS with the slope of 5 to 25 percent the place of planting should be done 10 to 25 centimeters below the place of emitter was achieved.
