Abstract
This study was carried out during three successive seasons 2010, 2012 and 2013 at two different experiments. The first one was carried out during 2010 seasons to evaluate the growth of Eucalyptus globulus, Casuarina equistifolia and Salix vemenalis trees grown on sewage effluent (Samatie drain) and agriculture domestic drain (Kafr Mahalet Missier). As for the second experimental was carried out at the form of Sakha Horticulture Research Station to study the effect of irrigation sources (Nile and industrial draing water), humic levels and their interaction on growth and chemical composition of C. equistifolia and E. globulus seedlings. The obtained results can be summarized as follows: as for first experiment generally, plants grown on Kafr -Mahalet Misier drain gave the highest significant values of vegetative growth parameters and higher significant mineral content in different plant parts. Concerning second experiment: 75% Nile water + 25% drainage water followed by 50% Nile water + 50% drainage water with 20% humic acid increased vegetative growth and root characters parameters and higher N, P, K, heavy metal contents and total carbohydrates in the two species under study.
