| Abstract | ||||
| A surface drip irrigation using a single lateral (SSDI) or double laterals/plant row (DSDI) , subsurface drip irrigation using single lateral (SSSDI) or double laterals/plant row (DSSDI), gated pipes (GP) and traditional surface irrigation (TSI) were applied with maize (Single Cross,10) during the summer season 2007 at Sakha Agricultural Research Station Farm , Kafr El-Sheikh Governorate, Egypt in order to study the effects of these irrigation systems on maize yield and water use efficiency. Both drip irrigation systems included 16 mm diameter drip-lines, with emitters discharging about 2L/h and spacing 0.5 m. The subsurface drip irrigation system was installed before the crop seeding, where its laterals (16 mm drip-lines), were buried 0.6 m apart at 15cm below soil surface so that they are not affected by the cultivation practices during the current growing season . The aluminum gated pipes (150 mm diameter) were located at the head of the irrigated field and connected directly with the irrigation pump. The experimental layout of irrigation systems included six replications for each of the six irrigation systems .The design of this experiment is randomized complete blocks(RCB). Water applied was obviously affected by irrigation systems . The DSSDI system was more effective since it received the lowest depth of irrigation water (55.7 cm.) followed by SSSDI (58.7 cm) and DSSDI system (60.1 cm). On the other hand, TSI system received the highest amount of irrigation water (79.4 cm) followed by GP system (72.2 cm). From the statistical analysis of the harvested maize yields, it has been found that their values are significantly different for all irrigation systems. Maize yields are high for GP and SSSDI irrigation systems and varied between 26.6 to 23.85 ardab /fed. for both systems, respectively. On the other hand , the grain yields are low with SSDI and DSSDI systems which varied between 20.14 and 19.04 ardab /fed. for both systems, respectively. The straw yield took the same trend that is found with the grain yield. Water use efficiencies expressing the maize yield per m3 water applied ranged from 0.96 to 1.355 kg/m3 water for TSI and SSSDI systems, respectively. The effect of different irrigation systems on water use efficiency took the following descending order: SSSDI > GT >DSDI >DSSDI > SSDI >TSI systems. Approximately, the same trend was found with irrigation water use efficiency which related to both grain yield and total water consumptive use. | ||||
