Abstract

Laboratory experiments were conducted to determine the effect of different levels of sludge (0, 40, 80, 120 and 160 tonnes/ha) and liquid sewage (50 per cent diluted and without dilution) on the germination per cent. dry matter yield of sorghum seedlings and macronutrients uptake by adopting Neubauer technique. The study revealed that the addition of sewage wastes caused reduction in the germination of seeds and in turn affected dry matter yield. Sewage amendments significantly increased the concentration as well as uptake of nutrients like P. K. Ca and Mg by sorghum seedlings compared to control. In the different soil layers studied, the P uptake was more from first (0-5 cm) layer and K. Ca and Mg uptake were more from 3rd layer (15 cm).
