Abstract

The purpose of the study is to evaluate the efficiency of surface irrigation systems with a modified perforated pipe system technique. (trailing perforated pipes) (T2), irrigation lengths beneath various furrows lengths and land slope 0.1% under the same condition and Treatments comparing with the traditional irrigation methods (T1). The experimental field was used for the growing season 2021–2022 clay soil on maize yield on the special farm on Kafr Taha – Shepin Elqanater – Qalupia. A plot of experimental area measured around 3.6 feddans. Two 1.8 feddan sub-plots were made from the experimental area plot. There were three treatments (L75) 75 m, (L100) 100 m, and (L125) 125 m for each sub-plot. At every treatment, the field test's breadth measured 18 m. Results showed that: increased crop production by using modified perforated pipe irrigation as compared with traditional irrigation techniques. Obtain the highest value of water application efficiency and water use efficiency under treatment L75 due to accurate leveling by Laser Land Leveling technique 0.1% slope and good water irrigation distribution by T2 system.
