Abstract
This study aimed to : Wheat crop is one of the most main crops in Egypt. Water resources are limited in Egypt and about 85 % of these resources are used for the agricultural sector. Therefore the objectives of the present work were : 1-Study the effect of raised bed as a planting method and deficit irrigation on the wheat yield and its attributes. 2- Study the effect of raised bed and deficit irrigation water on water productivity. 3- Evaluate how the deficit irrigation water and raised bed method affect some soil physical and chemical properties A split plot design with four replications was used. Planting methods occupied the main plots, while Irrigation treatments were arranged in the sub-plots. The planting method were flat (traditional method, F1), raised bed 70 cm width (F2) and 140 cm width (F3). Sub plots were devoted to deficit irrigation treatments were irrigation every 21 days (farmer treatment, (DI1) ; at 60 % depletion (DI2), the third one after 70 % depletion (DI3) and the fourth one after 80 % depletion (DI4) of the available soil moisture (ASMD).The obtained results could be summarized as follows : The mean grain yields for the two seasons obtained by DI1, DI2, DI3 and DI4 water regimes were 6741.3, 7232.0, 6381.3 and 5882.7 kgha-1 in the first season while it was 7400.0 , 7954.7 ,7020.0 and 6469.3 kgha-1 in the second season .respectively. Mean yields with F1, F2 and F3 were 6304.8, 6306 and 7237.9 kgha-1in the first season while they were 6735.0 , 6936.0 and 7962.0 kgha-1 in the second one, respectively. The overall average of the amount of water productivity for the two seasons were 1.62, 2.05, and 2.16kg (grain yield) m-3, respectively for DI2, DI3 , and DI4 While it was 1.45kg (grain yield) m-3under the control treatment (DI1). This indicates that deficit irrigation increased WP by about 32.8% compared to the farmer practice.Effect of deficit irrigation and plant method and the interaction on Some chemical and physical soil properties. Soil salinity Values of EC before planting ranged from 1.18 to 2.22dSm-1 while it ranged from 1.52 dSm-1to 2.25 dSm-1 after harvesting crop. The soi can be regarded as a normal non saline and non alkaline. Soil reaction (pH)The obtained results showed that soil pH values slightly increased after harvesting relative to those before planting Soil Bulk density Bd and Total porosity TP The values of Bd were significantly increased at harvesting time, compared with these before planting. total porosity had the opposite trend of the bulk density .i.e increased upon the decrease of the Bd. It could be concluded that : The use of deficit irrigation and raised bed techniques reduced irrigation water application, and improve water productivity.
