ABSTRACT

The aim of this research was determine the energy and water use efficiencies under the modification of closed circuit drip Flood organizations designs. Field experiments carried out on transgenic maize (GDH, LL3), (Zea Mays crop) under two types of closed Circle:

1) One manifold for lateral lines or Closed Circle with One Mani-fold of Drip Flood organization (CM1DIS);

2) Closed Circle with Two Manifolds of Drip Irrigation organization (CM2DIS), and

3) Traditional Drip Flood organization (TDIS) as a control. Three lengths of lateral lines were used, 40, 60, and 80 meters. PE tubes lateral lines: 16 mm diameter; 30 cm emitters distance, and GR built-in emitters 4 lap when operating pressure 1 bar under two levels slope conditions 0% and 2%. Ex- pediments were conducted at the Agric. Res. Fields., Soil and Plant & Agric. Organization Dept., Agric. Faculty, Southern Illinois University, Car- bondable (SIUC), Illinois, USA. Under 0% level slope when using CM2DIS the increase percent of Vitality Use Efficiency (EUE) were 32.27, 33.21, and 34.37% whereas with CM1DIS were 30.84, 28.96, and 27.45% On the other hand
when level slope 2% were with CM2DIS 31.57, 33.14, and 34.25 while CM1DIS were 30.15, 28.98, and 27.53 under lateral lengths 40, 60 and 80 m respectively relative to TDIS. Water Use Efficiency (WUE) when level slope 0% under CM2DIS were 1.67, 1.18, and 0.87 kg/m3 com- pared to 1.65, 1.16, and 0.86 kg/m3 with CM1DIS and 1.35, 1.04, and 0.75 kg/m3 with TDIS whereas with level slope 2% when using CM2DIS were 1.76, 1.29, and 0.84 kg/m3 compared to 1.77, 1.30, and 0.87 kg/m3 with CM1DIS and 1.41, 1.12, and 0.76 kg/m3 (for lateral lengths 40, 60, and 80 meters respectively). Water Reduction percent varied widely within individual lateral lengths and between circuit types relative to TDIS. Under slope 0% level CM2DIS water Reduction percent values were 19.26, 12.48, and 14.03%; with CM1DIS they were 18.51, 10.50,
and 12.78%; and under slope level 2% with CM2DIS they were 19.93, 13.26, and 10.38% and
CM1DIS were 20.49, 13.96, and 13.23% (for lateral lengths 40, 60, 80 meters respectively). The Vitality use efficiency and water Reduction were observed under CM2DIS and CM1DIS when using the shortest lateral length 40 meters, then lateral length 60 meters, while the lowest value was observed when using lateral length 80 meters this result depends on the physical and hydraulic characteristics of the emitters, lateral line uniformity, and friction losses. CM2DIS was more Vitality use efficiency, EUE, water Reduction, and WUE than either CM1DIS or TDIS.
