Abstract EN

Field Experiments were conducted at the Experimental Farm Mayfaa-Hager at the Agricultural Research Station for the East Coastal zone Hadhramout Governorate of Yemen in two consecutive summer seasons 2011-2012 and 2012-2013 to estimate effect terms of water on yield performance highest tuber and vegetative growth of two sweet potato cultivars (Ipomoea batatas L) The two sweet potato cultivars tested were Mayfa-1 and Red Mayfa.to four irrigation interval (1 2 3 4) weeks.

The plot size was (24 m2).

The treatment combinations were arranged to a randomized complete-block design.

After six and half months, all sweet potato cultivars were harvested and yield yield quality and vegetative growth were recorded.

The Mayfaa-1 cultivar gave significantly the highest yield then Red Mayfaa.

Significant differences reaction were recorded among all tested of two sweet potato cultivars regard to factor irrigations.
