The production of sugar cane increases the demand for ethanol, sugar and electricity recently influenced by population growth, resulting in expansion of cultivation to regions where climatic conditions are often not conducive to production due to drought, thus, irrigation will be essential to avoid losses due to this limitation. Population growth leads to higher volume of sewage, capable of use in agriculture, such as the use of effluent as shown abundant water resources, can be used as drip irrigation, which is important both economically by recycling nutrients and reducing the costs generated by fertilizer , and environmentally minimizing its launch in the receptor and reduce the use of surface and groundwater by keeping them for the noble uses. However, few studies addressing the reuse of treated sewage on the growth, nutrition and physiology of the culture of sugar cane and its water relations, especially in subsurface drip systems. The experiment is a randomized block with nine treatments being: without irrigation (T1), irrigation with sewage more complementary to 20 cm (T2), only drain 20 cm (T3), more sewage complementation to 40 cm (T4), only sewage 40 cm (T5), water irrigation reservoir complementation more than 20 cm (S6) only water reservoir 20 cm (7), the water reservoir 40 cm (8) and only water from the reservoir 40 cm (T9). This way, assumes that the use of different qualities of water at different depths of burial of the irrigation system may influence the nutrition, physiology and production of sugar cane. (AU)
