Title: Utilization of treated sewage water for forage production
Author: Malik,Nasr Malik
Abstract: Worldwide, the Treated Sewage Water (TSW) reuse for irrigation purposes has been advocated since it shows substantial economic and agricultural benefits. This study investigates the potentiality and effect of the effluent of the algal sewage treatment plant south of Khartoum on forage production. About 9 million gallons are produced per day, which can be recycled. The study evaluates fodder production in locations 1, which represent long-time application of TSW and location 2 as control. Both locations received normal water and TSW for two consecutive seasons. Forages investigated belong to family Poaceae and cultivars of Sorghum bicolor “Abu Sabaien, Pioneer, Panar and Speed feed”. Irrigation by TSW resulted in relatively taller plants, plants of all cultivars looked vigorous and healthy, with less fiber content, high protein values and significantly higher dry yields compared to those irrigated by normal water at 0.05 levels of significance and no symptoms of phytotoxocity were observed. The yield of Pioneer was significantly higher than the rest of the cultivars at 0.05 levels. TSW showed no effect on soil characteristics and no serious pollution probed moreover, can be safely used for the production of fodder crops of the family Poaceae that produced higher yields and better quality.
