| Summary, etc. | A field experiment was conducted at a pin private farm at Wadi El-Natrown during the summer season 2008, to study the effect of irrigation water quality, water quantity and lateral line spacing on the trickle irrigation system performance, water saving. maize crop yield. yield components. water use efficiency and net profit in sandy soil conditions. The results obtained can be summarized as follows: The emitter flow rate indicated that there is gradual decrease with gradual lowering of the operating pressure. The manufacturing coefficient of emitter variation ranged between 0.05-0.07. it could be classified r.s average. The exponent of emitter x was equal to 0.38 meaning that the flow regime is practically turbaulent. The highest emission uniformity at the 100% of ET actual were 96.50, 91.75 and 86.25% under fresh. fresh & saline and saline water, respectively . The highest values of EU and AE were found under fresh water and 100% of ET actual and the highest value of emitter clogging were found under 100% of ET actual and saline water. The average water applied of 2355, 1885 and 1415 m3 /fed, were obtained under 100, 80 and 60% of ET actual respectively. Increasing the lateral line spacing from 0.70 to 1.40 m, the irrigation water applied was decreased under all treatments. The results indicated that the average fresh water saving 877 and 1753 m3/fed compared with irrigating fresh & saline and saline water. The highest grain yield of 4.3 Mg/fed were obtained under fresh water, 100 % of ET actual and 1.40 m lateral line spacing. but the lowest values of 1.3 Mg/fed were obtained under saline water, 60 % of ET actual and 0. 70 m |
