TRICKLE IRRIGATION SYSTEM PERFORMANCE REUSING TREATED WASTEWATER FOR IRRIGATING JOJOBA PLANT

Abstract

All experimental field was located at the experimental farms at Al-Gabal Al-Asfar, El- Al-Khankah, Al Qalyubia Governorate 30˚12 ̏ 07.9 N, 31˚24 ̏ 39.7 E. Main plot area (21 x 25) m2 for drip irrigation system was selected for carrying out the experiments and divided into four sub-main plots. Two Sources of water (well water – treated wastewater) were used and two different of the emitter (2 l/h self-compensating, 2 l/h non-self- compensating, 8 l/h self-compensating, 8 l/h non-self-compensating). The aims of these treatments are to investigate performance by using treated wastewater and study the effect on drip irrigation system exists, soil and cultivated plant. Results indicated that the end of the experiments after six weeks by using treated wastewater flow rate for emitters (2 l/h self, 2 l/h non self, 8 l/h self and 8 l/h non self) were (1.59 – 1.28 – 6.55 -7.08) L/h, respectively. Emission uniformity was (80.81 – 68.75 – 83.17 – 89.39) %, respectively. Accumulative clogging ratio was ranged between of (2.87 – 16.64), (3.21 – 37.98), (5.04 – 11.3) and (1.3 – 19.2) %, respectively. The proportion of heavy elements in the soil not detected by using different sources of water. The proportion of micro and heavy nutrient in jojoba (Simmondisa Chinensis), (Cu – Mu - Zn – Fe – Co – Pb – Cd - Ni) were (1.79 - 8.66 - 4.32 - 10.25 - 3.45 - 1.55 - 1.58 - 1.61) meg L-1 for seeds, and (1.95 - 8.84 - 4.55 - 13.04 - 3.64 - 1.59 - 1.69 - 1.69) meg L-1 for leaves, respectively.
