| 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. | ||||
