Alternative irrigation and productivity of sweet sorghum [electronic resource].

Includes reference.

Two experiments were conducted during the summer seasons of 2002 and 2003 at Sakha Agricultural Research Station (Middle North Nile Delta) to improve surface irrigation performance, through using the other-row technique. The consequent effects of applying such method on total water applied, water distribution efficiency, yield and field water use efficiency, for sweet sorghum were considered. Irrigation treatments were: traditional furrow irrigation (EFI, trt. A), III irrigation fixed (AFI, tft. B) and 1/1 irrigation exchange (AFI, trt. C), obtained results showed that: . The highest value of stripped stalk yield (20.40 ton/fed. i.e. 48.96 ton/ha) was obtained under the traditional or every furrow irrigation i.e. treatment A. While the highest yield of juice and syrup were resulted from AFI (Ill exchange) with mean values of 8.98 and 2.25 ton/fed. i.e. 21.55 and 5.4 ton/ha, respectively. Whereas the extraction percentage of juice and syrup were the highest with values 46.7 and 11.7% under API (Ill exchange). On the other hand, the highest T.S.S. of 11% was resulted from the traditional irrigation. . Average seasonal water applied to sweet sorghum, was ranged between 2415.7 m3/fed. (57.5 cm) for treatment B to 3186.6 m3/fed. (75.9 cm) for treatment A. This amount included sowing irrigation, which equalized an average of 399.0 m3/fed. or (9.5 cm). . Average crop consumptive use (C.D.), could be arranged in descending order as: 3099.6 (73.8 cm) > 2530.3 (60.3 cm) > 2324.0 (55.3 cm) m3/fed. for treatments A, C and B respectively. The corresponding. rate of consumptive use, could be arranged as: 0.55, 0.45 and 0.41 cm/day for the same treatments, respectively.
