| Abstract | ||
| This study was conducted during the two seasons of 2001/2002 and 2002/2003 at Sakha Agric. Res. Station, Kafr EI-Sheikh Governorate. The aim of this work was to study the effect of the relatively new surface irrigation technique (surge flow irrigation) on consumptive use (CU), water application efficiency (Ea), water use efficiency (WUE), water utilizations efficiency (WUtE) and productivity of faba bean, under clay soil condition. Three water irrigations discharge (D): 4, 6 and 8 Us as main treatments. Four irrigation treatments were used as a subtreatments and were arranged in split plot design, as following: 11 continuous irrigation, 12 = 20 min. with cycle 10 min. On and 10 min. Off, b= 25 min. with cycle 10 min. On and 15 min. Off and 30 min. with cycle 10 min. On and 20 min. Off. Data revealed that consumptive use is higher under continuous irrigation than the other surge irrigation treatments. The average values of CU were 41.8, 40.4, 37.5 and 33.4 for treatments 1" 12, 13 and 14, while it was 36.95, 38.31 and 40.25 for 01, 02 and 03 irrigation discharges, respectively. Values of Ea, WUE, WUtE and seed yield were increased in case of surge flow under similar conditions. The best results regarding to CU, Ea, WUE , WUtE and seed yield were obtained from using 14 treatment. | ||
