The effect of irrigation with raw and treated sewage water on Balady orange plants grown in clay and sandy soil [electronic resource].

Includes references.

A pot experiment was. conducted during 2009 and 2010 seasons in Horticulture Research Sation in Alexandria, Egypt to study the effect of irrigation with raw and treated sewage water on the vegetative growth and leaf mineral composition of Balady orange plants grown in clay and sandy soils, as well as, the effect on soil chemical characteristics. The obtained data showed that growth rate, fresh and dry weight of top and, root of plants were increased with raw and treated sewage water treatments. Leaf and root minerals contents (N, P, K, Na, Fe, Mn, Zn, Cu, Pb, Cd, Ni and Cr) increased by irrigating with raw and treated sewage water for plants grown in both clay and sandy soils. Also, leaf and root proteins contents showed a marked increase as a result of the different treatments. Values of EC, pH, soluble ions, total N available P, K, Fe, Zn, Mn, Pb, Ni. Cd, and Cr were increased in both soils type irrigated with raw and treated sewage water. The clay soil indicated more positively trends than the sandy one.
