Shortage of precipitation and restricted irrigation water resources is the major defy for agricultural dilating policies and strategies. On the other hand, there is an elevated apprehension to rise the area of wheat farming in require to convention the growing regional consumption. The great defy is to raise wheat output using same or lower quantities of irrigation water. an Experiment was carried
out through two winter sequential seasons of 2020/2021 and 2021/2022, at a special ranch in El- Salhia El-Gedida area, El- Sharqia Governorate, Egypt, to investigation the effectiveness of two irrigation systems floppy sprinklers (FSS) and center pivot (CPS) at various irrigation water levels (IR=100, 90, 80, 70, and 60% studied depends on crop evapotranspiration) and three chemical fertilizer rates (MFR=100, 80 and 60% of recommended chemical fertilizer N, P, K rates) on the marketable yield (MY), crop goodness standards, seasonal actual evapotranspiration (ETa), water use efficacy (WUE) and irrigation water use efficiency (IWUE) for wheat bread (Triticum aestivum L.) were investigated. The experimental purpose was a split-split plot design with three replicates. The discussion reported that; 1) the crop yield and crop goodness standards of winter wheat gave the maximum values at FSS irrigation system, IR=100% and MFR=100 treatments for both seasons. 2) Seasonal ETa gave the minimum values: 159.19 and 155.72 mm for both seasons, respectively, under FSS irrigation system, IR=60% and MFR=60 treatments. 3) The highest values of wheat WUE and IWUE were 5.38 and 3.21 kg m-3; 5.56 and 3.29 kg m-3 for both seasons, respectively, at FSS irrigation system, IR=70% and MFR=80 treatments. This study concluded that the cultivation of winter wheat at FSS irrigation system, IR=70% and MFR=80% treatment could be saved about 38% of added irrigation water, 20% of the total chemical fertilizers rates additive and increased yield of the winter wheat about 11.33 and 10.85% for both seasons, respectively, compared with that under the control treatment (CPS irrigation system, IR=100% and
