Irrigation using the perforated pipes system is a way for furrow and border irrigation, and it has been perhaps one of the simplest and most effective ways of improving the flexibility and efficiency of water supplies. The main objective of this work is to study the possibility of utilizing plastic microfilm as a perforated tube for irrigation. Also, studying some factors that affect water uniformity distribution along perforated plastic microfilm tubes (PPMT). Plastic microfilm tubes with different diameters of 190, 254, and 320 mm were investigated to use as perforated tubes for irrigation with orifices diameters of 20, 40, 60, and 80 mm. The obtained results of the tube diameter of 190 mm generally showed that the pressure head dropped gradually in the perforated plastic microfilm tube and this dropping trend ended after that increased gradually until the tube ended. The pressure head variation (Hvar) along the tube was about 31.25% and 25.81 % for orifices diameters of 20, and 40 mm, respectively. The actual discharge (Qact) of the orifices were closely varied along the tube length. Meanwhile, the theoretical discharge (Qth) dropped gradually in the tube. The discharge variation (Qvar) along the tube was about 40.49% and 12.06% for orifices diameters of 20, and 40 mm, respectively. The pressure head variation value ranged from 25.81 to 64.71% and the discharge variation ranged from 12.06 to 58.66% for investigation conditions.

“…Modern surface irrigation methods and practices can achieve significantly higher performance levels than existing methods and practices, (Strelkoff et al, 1999). Gated pipe irrigation is a type of irrigation in which conventional head ditch and siphons are replaced by an above-ground pipeline (El Awady et al, 2009). The app1iction through the irrigation system of plant nutrients (fertigation) or other chemicals (chemigation) has recently expanded because of efficiency and convenience (Breslar, 1977;Elfving, 1982;Papadopoules, 1985).…”

The experimental fieldwork was carried out in sugarcane production areas in Upper-Egypt at Qena Governorates during growing season 2010-2012. Sugar cane is the major source of sugar production in Egypt. Insect pests are limiting factors affecting its production. One of which, is the soft scale insect, Pulvinaria tenuivalvata (Newstead) (Hemiptera: Coccidae). As a new pest, it threatens sugar cane cultivation in Egypt. High scale densities cause significant reduction in sugar cane weight and juice quality, particularly sucrose content. To avoid the sugar cane infection with the soft scale insect, (Pulvinaria tenuivalvata), it is necessary adding diesel fuel through irrigation water. But in the cultivated areas using gated pipes system, irrigation water flowing through closed pipes from branch canals to the fields. It is difficult to add diesel fuel into these canals. Therefore, this paper describes design and locally manufactured of a simple and inexpensive fertilization system suitable of small holding in Egypt called "Vacuum Fertilization System" using in both function, add diesel fuel or any chemicals and fertilization system through gated pipes or any piping closed system during irrigation operation, in spit of, their were another systems using solution fertilizer; but these systems are not available directly in this region and its expensive. Also, evaluating the performance of the designed mechanism in performing this operation. The results showed that: 1-There were a drop in the pressure head measured at the first portion of the gated pipe due to accumulative friction head losses effect and then there were a gradual increase in it due to the increasing in superimposed pressure head, decreased the effect of accumulative friction head losses. 2-The slope of the curve of the actual measured pressure head (hon) along the gated pipe representing the effect of gated pipe length on the pressure head variation, and its value was about 18.2 %. 3-The outlets discharge rate along the gated pipe system were dropped at the first portion of the gated pipe due to accumulative friction head losses effect and then there were a gradual increase in it due to the increased in superimposed pressure head overcome the effect of accumulative friction head losses. 4-The water distribution uniformity along the 18 meter apart of the 6 inch gated pipe before using fertigation system, was about 95.4%. But the water uniformity distribution along the gated pipe during fertigation system using fertilization system was about 93.8%. This mean that the water distribution uniformity decreased slightly during fertigation system using fertilization system under irrigation gated pipe system due to apply the fertilizer through irrigation water, consequently change in irrigation water density affecting outlets flow rates through irrigation gated pipe system. 5-The fertilizer concentration uniformity through the gated pipe system was about 98.1%. This means that, the concentration variation along the gated pipe system was about 1.3%. The reason of t...

Two field experiments were carried out at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt, to study the effect of different surface irrigation systems (basin irrigation, bed irrigation and gated pipes) and foliar application of some growth stimulants (control, amino acids, humic acid, compost tea, seaweed extract and yeast extract) on yield and grain quality of bread wheat (Giza 171) during 2019/2020 and 2020/2021 seasons. Irrigation systems significantly affected on most characters studied. Using gated pipes was superior to the other irrigation systems in yield and its components (number of spikes/ m 2 , number of grains/spike, 1000-grain weight, grain yield /fed and straw and biological yields/fed) and grain quality (protein, wet and dry gluten %) especially basin irrigation which registered the lowest ones. However, moisture, ash, fats and fiber percents in grains did not significantly affect by different irrigation systems. Foliar application of yeast extract or seaweed extract exhibited superiority in all yield and its components as well as grain quality (protein, wet and dry gluten %) in comparison with other tested growth stimulants especially control. Treated plants with compost tea and untreated plants recorded the highest carbohydrates in grains. However, moisture, ash, fats and fiber percents in grains did not significantly affect by various growth stimulants. The interaction between irrigation systems and growth stimulants was found to be significant for most characters studied. Significant increases in most effective yield and grain quality traits were detected by irrigated plants with gated pipes and treated with yeast extract or seaweed extract. It could be concluded that irrigated plants with gated pipes and treated with yeast extract was the best combination treatment for maximizing grain yield and its quality under similar environmental conditions of the experiment site.
