| Abstract | ||
| The present study aims to design and evaluate of Self Control Dripper”SCD”to control the water management in sand soil. The study evaluate self control dripper under different factories as rubber thickness”TH”of 3.0, 3.5 and 4.0 mm, sensor volume”V”of 25 and 75 ml, burial depth of 5, 10,15 and 20 cm, water head”H”40, 60, 80 and 100 cm and water outlet length”L”of 10, 20 and 30cm. The evaluation achieved by wetness radius of soil water,"R”cm, adding water”Q”l and adding water time”T”min. The results concluded that; the best size of sensor was 25 ml and the best rubber thickness of were 3.5 to 4 mm.The relation between mention factors and wetted radius R (cm) was: | ||
