Abstract
A field experiment was conducted in during the fall of 2016, in terms of Habbaniyah–spend khalidiyah–Anbar province in a sandy clay loam, to study the effect of stress water and irrigation management in efficient use of the water potato, where perfusion has operations at 40, 50 and 60% depletion of available water. Water added in three ways, firstly addition depth once, for added half the depth and the addition of the second half after 6 hours of the first add-on, add a three-included a division of the depth of irrigation to three sections separating them duration of 6 hours, the study treatments distributed in accordance with the randomized complete block design (RCBD) of three replicates. Potatoes were planted on 13-09-2016, Use American evaporation pond Class A at the irrigation time. Calculated total yield and the efficiency of water use.Study has been showed that an increase in the average total yield reached 22.73 Ton h -1, when depletion 40 % of available water and averaged efficiency of water use 12.94 kg m3 when depletion 50 % of available water for any style and added. In addition, the style additive triple is distinction in giving highest value of total yield and used efficiency if it reached 23.90 Ton h -1, 14.17 kg m-3 sequentially
