Abstract
The limitation of water resources and the remarkable increase in population should be forced research workers to find ways for saving water without significant reduction in yield. The objective of this paper is to study the interaction effect of deficit irrigation and raised bed on wheat yield, water productivity and water saving in north Nile delta, Egypt. Two field experiments were conducted at Sakha Agricultural Research Station, Kafr El-Sheikh governorate during the two successive seasons of 2012/2013 and 2013/2014. A split plot design with four replications was used. Irrigation treatments occupied the main plots, while planting methods arranged in sub-plots. Three planting methods were flat (traditional method, F1), bed 70cm wide  (F2)  and raised bed 140cm wide (F3). Four deficit irrigation treatments were irrigated  every 21 days (farmer treatment, I1); the second one after 60% (I2) , the third  one  after 70% (I3) and the fourth one after 80% (I4) depletion of available soil moisture (ASMD).
Results showed that mean of amount of irrigation water applied for DI1, DI2, DI3 and DI4  were 4759.2, 4497.6, 3808.8, and 3360.0 m3/ha., respectively, and means of water table contribution to ETc were 559.2 and 765.6 m3/ha. for I3 and I4 , respectively. Means of irrigation water applied were 4524, 4034.4  and 3763.2 m3/ha. for  F1,  F2  and F3,   respectively. F3 and F2  saved 17% and 11% of irrigation water compared with F1, respectively. F3 significantly increased grain and straw yields by 16 and 18% compared to F1. The interaction between DI2 and F3  and between DI1 and F1 resulted in higher grain and straw yields.  Means values of water productivity were 5.7, 6.1 and 6.1 L.E /m3 correspond to 1.2 , 1.18 and 1.5 kg grain/m3 water applied for F1, F2 and F3 respectively .
