Fertigation management under subsurface drip irrigation system for imroving tomato yields and agricultural environment [electronic resource].

Includes references.

Field experiments were carried out for two successive growing seasons (2005 and 2006), at the Experimental Farm of Faculty of Agriculture, Ain Shams University, which located in EL-Bustan Region, Beheira Governorate (which represents sandy soils conditions of Egypt), to clarify the role of fertigation technique management for tomatoes yields improvement. Results revealed that the application of the total tomato plantsfertilizer requirements (l00 kg-N per feddan) with bi-weekly fertigation interval and injecting fertilizers within the second-third of the total irrigation time may be an effective technical package of fertigation management under subsurface drip irrigated sandy soils for improving tomato yields and enhancement of the agricultural environment under drought ecosystem conditions.
