A feasible and practical option is a regulated spreading of OMW into the soil. This study aimed to investigate the sustainable reuse of OMW through land application to enhance soil quality and wheat growth performance under rain-fed conditions. OMW was spread at 20, 40, 60, 80, and 120 m 3 ha −1 at two sites. Soil physical and chemical properties were measured after OMW application and after harvest. Wheat growth performance and leaf nutrient content were determined. This study revealed no deleterious influence of OMW application on soil properties and wheat growth at the two locations for all OMW application doses. The OMW land spreading improved significantly wheat growth by increasing the biological yield (BYLD) (8.4 to 36.5%), grain yield (GYLD) (20.1 to 79.4%), and harvest index (HI) (4.2 to 60.2%). Based on the measured soil chemical parameters and wheat grain yield, we can suggest that OMW application rate at 60 m 3 ha −1 could improve significantly wheat growth without significant negative impact on soil properties. In conclusion, we recommend using OMW as suggested in this study for wheat. However, still the long-term application of OMW assessment and local legislative adaptation of saving use are necessary.

To examine the effect of drought stress (DS) on germination rate and seedlings growth, the seeds were exposed to induced osmotic potentials (OP;-0.75 and-1.2 Mpa), in addition to the control. Er/Apm variety did not show any significant decrease in germination rate in response to OP. The most drought tolerant varieties at seedling stage were Morocco9-75, Yarmouk, Acsad 176, and WI2291 with minimal biomass losses. Varieties were also tested against four DS treatments: continuous DS (Dcon), early DS (Dearly), late DS (Dlate) and a combination of Dearly and Dlate (Dearly+late) treatments. Grain yield in the control treatment (continuous irrigation) was almost two times greater than Dcon treatment, while the reductions in Dearly, Dlate and Dearly+late treatments were 12.9, 26.1, and 33.6% compared to the control treatment, respectively. WI2291 and Yarmouk showed the minimal grain yield losses in response to DS at DDS and their ranks in response to DS remained almost unchanged at DDS, and consequently they could be considered as a potential source of genes for drought tolerance.

The water stress regimes are T 1-75% of available water served as the control (non-stress), T 2-25 % of available water after emergence served as Sustain water stress, and T 3-25 % of available water at booting stage served as late water stress respectively. The objective of this study was to identify drought tolerant varieties by using drought susceptibility index (DSI) under different water stress treatments to set recommendations on their possible use in drought tolerance breeding programs. Results showed that water stress reduced grain yield and its components. Sustained water stress (T 2) exhibited the highest reductions in grain yield and its components. Number of spikes plant-1 and number of kernels spike-1 were more sensitive to water stress than 100-kerrnel weight. From the concept of drought susceptibility index DSI (less grain yield losses), local landrace was the most tolerance variety because it exhibited low grain yield losses under water stress treatments. Accordingly it could be considered as a potential source of genes for drought tolerance in plant breeding.
