Two field experiments were carried out during winter seasons 2020/2021 and 2021/2022 at the Research
and Production Station, National Research Centre, El-Nubaria, El-Behira Governorate, Egypt. to evaluate yield
and yield component for two bread wheat cultivars (Giza 171 and Misr 1) under sprinkler and dripp irrigation
systems with using four concentrations of water salinity irrigation. A split-plot design with three replications
was used. Wheat cultivars were randomly distributed in the main plots while, while water salinity treatments
occupied the sub-plots in both seasons. Results showed that Misr 1 cultivar recorded the highest values and
highly significance for plant height, No. spikelets spike-1
, weight of spike(g) and grain yield fed-1
. While, Giza
171 cultivar gave the highest values and highly significance for tillers number and spikes/ m-2under sprinkler
and drip irrigation system in over the combined analysis. cultivar and its components of wheat i.e. plant height
(cm) , tillers number and spikes/ m2
, No. spikelets /spike, weight of spike (g) and grain yield/fed were highly
significant affected by water salinity concentrations under sprinkler and drip irrigation system in the combined
analysis. Significant impact of interaction between wheat cultivars and water salinity was gained for plant
height, tillers number/ m2
, No. spikes/ m2 and weight of spike under sprinkler irrigation system in combined
data. Significant effect of interaction between wheat varieties and water salinity was obtained for Tillers number
m-2 and No. spikelets spike-1 under drip irrigation system in combined data. It could be complemented that
under the conditions of the experiment, planting Misr 1 cultivar with irrigated water salinity level (650 ppm)
treatment under sprinkler and drip irrigation system is recommended.
