Possibility of sand encroachment control using prosopis julijlora and tamarix articulata plants grown under different cultivated practices at Toshka Region [electronic resource].

Includes references.

Field experiments were conducted at Toshka region in the period 2003 to 2005. These experiments were carried out to study the possibility of sand shifting control using Prosopis juliflora (small trees) and Tamari;x articulata (high shrub) grown under different cultivation practices viz. shading with maize plants and irrigation water levels. Obtained results (in the first part) emphasized that the growth parameters ofProsopisjuliflora and Tamari;x articulata were higher in the lIeatments of irrigation water supplemented at a rate of 8 or 12 Iiter/treelbour in combination with shading by maize plants rather than water supplemented at a rate of 4 liters/hour/tree. Vice versa, light intensity gave opposite trend of results. Also, growth characters after shading period (the second part) were significantly increased with the increasing of irrigation water levels.
