Two field experiments were carried out at Sakha Agricultural Research Station during the two successive season 1999/2000 and 2000/2001 growing season in the North Middle Nile Delta region to study the effect of amount of applied water on some water relationships and yield of faba bean. The main treatments were irrigation depth which were D1 = irrigation till water depth reached 25 cm above soil surface, D2 = irrigation till water depth 5.0 cm and D3 = irrigation till water depth 7.5 cm, while the sub treatments were furrow width which were F1 = furrow 60 cm wide and planning on one side, F2 = furrow 120 cm wide and planting on both sides and F3 = furrow 120 cm and planting on both sides plus middle.
Increasing depth of irrigation water increased the amount of applied water in the growing season. The highest mean values occurred with 7.5 cm giving 2022 and 2041.9 m3/fed. In the two seasons, respectively. Lowest values occurred with 2.5 cm giving 1400.4 and 1453.5 m3/fed. In two growing seasons, respectively. The highest mean values for water applied were F1 giving 1527.8, 1767.3 and 2233.3 m3/fed. Under D1, D2 and D3, respectively. The highest mean consumptive use (CU) was 1819.3 and 1695.7 m3/fe. In the first and second season, respectively. Water consumptive use was higher under F1 treatment the highest CU values for D treatments were 1633.5, 1822.5 and 1924.5 m3/fed. Under D1, D2 and D3, respectively. Bean yield was highest with D2 giving 1490.0 and 1449.7 kg/fed. in the first and the second seasons, respectively. F3 gave highest yield among F treatments.
