Abstract
Irrigation scheduling in terms of frequency rate and duration expresses how water is used on the farm. The technique involves two decisions: - when to irrigate (timing) and how much to apply (quantity) Ideally, they are planned so that adequate water can be delivered to the farm during the peak crop water-use period. This research aims to comparison two irrigation systems the drip irrigation and open furrow irrigation. Split area of 36m2 was designed for both irrigation systems. Onions were planted in these areas. Three moisture content levels were selected for this study namely 100 % (M1), 75 % (M2), and 50 % (M3) of the available water. The results show that the generally, the moisture content decreases at deeper soil layers or being far from the dripper or furrow systems. The electrical conductivity (EC) value increases in horizontal and vertical directions and so chloride. The data indicated that salts are accumulated according to direction of water flow. Generally, the EC and chlorides concentration increased by decreasing the quantities of water applied rates. The salinity increased in the following order: drip and furrow irrigations. Comparing the three different applications water under irrigation systems, a significant relation was remarked. Meanwhile, when the two systems irrigation is compared due to the application water, no significant relation obtained. Under drip irrigation, each k watt of power produced 273 kg of yield in the first season increasing by 73.55 and 64.56 % than the furrow system respectively.
