Abstract

The present study aimed to evaluate the trailing perforated pipe effect on irrigation efficiency and maize production using UPVC pipe with 200 mm inside diameter. The orifices were located at 75 cm spacing (the same spacing between furrows) with a circular orifice (25mm D) attached with a 2 m plastic hose. trailing perforated pipe is a new method to be used to reduce the soil erosion, directing the exit of irrigation water towards the irrigation furrows, can be using the system on irrigating any kinds of crops planting through any furrows spacing, distribute water into furrow irrigated fields based and water. The results revealed that the average values of the water a dvance, recession and opportunity times for gated pipe and trailing perforated pipe at 0.1% lands leveling slopes and furrows lengths 100 m were 88, 268 and 180 minutes and 84, 264, and 180 minutes respectively, the highest water amount applied was found at gated pipe irrigation system (2766 m3/feddan). Water distribution efficiency were 95.8% for gated pipe and 97.2% for trailing perforated pipe. The highest value of crop production was 3695 kg/feddan/year in case of using the trailing perforated pipe. The results showed that the average values of maize water use efficiency increased at using trailing perforated pipe irrigation system of 1.37 kg/m3 than the gated pipe irrigation system by 1.32 kg/m3. From the above-mentioned results, it can conclude that, the trailing perforated pipe irrigation system is better than the gated pipe for improving irrigation efficiency and maize productivity.
