Abstract
The effect of the applied irrigation system and nitrogen fertilizer sources are
two major issues for the growth and yield of potato. A field experiment was conducted
on a clay loam soil at Mansoura University Farm during the late winter planting
season of 2004. This research aimed to study three different irrigation systems
(subsurface& surface drip and furrow) and six different treatments of nitrogen fertilizer
(control, 100% mineral, 100% organic, 100% bio-fertilizer, 50% mineral + 50%
organic, 50% mineral + bio-fertilizer, 50% organic + bio-fertilizer). Results indicated
that the use of surface drip irrigation system and the application of 100% mineral or a
combination of mineral and bio-fertilizer gave better results. The use of subsurface
drip irrigation and 100% mineral fertilizer gave the highest tuber yield (15.93-
ton/feddan). Subsurface drip irrigation system proved its feasibility and applicability
for irrigating potato crop.
